This study presents findings from a qualitative study conducted in two relatively remote, primarily rural regions of the Canadian province of Quebec whose resource-based economic structures exacerbate inequalities between men and women. The purpose of this study was to understand how violence and homelessness intertwine in women's life courses in such regions. On the basis of past research showing that gender socialization around traditional roles and conservative values is particularly tenacious in non-urban areas, we conducted life-course interviews with 22 women in 13 different towns and villages of these two regions. Our content analysis of these interviews showed that specific social responses have forced women to maintain relationships with their aggressors or with people who have protected them, thus relegating these women's lives to the private sphere while reducing their opportunities for social participation in the public sphere. These social responses, together with women's economic and social disadvantages in these regions, were also the main factors that explain homelessness experienced by the participants in this study. Our analysis of these responses illustrates the patriarchal social structure of power in these regions, which is perpetuated in the interpersonal, institutional, and representational dimensions and keeps women in precarious, subordinate social positions, while ostracizing or punishing women who try to resist.

Dying with dignity is important in Western culture. The aim of this qualitative study was to explore how Asian Buddhists, exposed to Western cultures, perceive death and dying with dignity, and examine their preferences for end-of-life care. We interviewed 15 Asian Buddhists living in Montreal (Canada). Participants regarded death as inevitable, while a good/dignified death had to be natural, peaceful, and, most of all, conscious. Most preferred palliative care to medical-aid-in-dying and emphasized death preparation through daily contemplation of impermanence. Care providers' understanding and respect of Buddhist patients' perception of a dignified death might help facilitate this important transition. [ABSTRACT FROM AUTHOR]

Dating violence (DV) among youth is widespread and is now established as a significant public health problem. Yet, few studies have assessed DV experiences among youth with same-gender or multi-gender dating partners, and most failed to consider bidirectional DV. We analyzed self-reported dyadic concordance types (DCTs) among 295 youths (52% girls) who dated same-gender and multi-gender partners in the last 12 months using an adapted version of the Conflict in Adolescent Dating Relationships Inventory. Youths were classified in one of three DCTs: self-only (unidirectional perpetration of DV by the participant), partner-only (unidirectional victimization perpetrated by their partner) or both (bidirectional DV, where partners are both perpetrators and victims of DV). Overall prevalence rates of DV among sexual minority youths (SMYs) range from 11.5% for threats, to 51.2% for psychological violence, with physical and sexual violence reported by about one-fourth of participants. The both DCT was the most common pattern for psychological (59.6%) and physical (50.6%) DV across gender, while most threatening behaviors were reported as perpetrated by the partner only (47.1%). Girls were more likely to report sexual DV as partner-only perpetrated (63.6%), whereas boys reported higher rates of both (44.2%) and self-only (34.9%) perpetrated sexual violence. Because healthy intimate relationships can play a supportive and positive role in transitioning toward adulthood, it is crucial that DV prevention becomes more inclusive of sexual and gender diversity.

Attachment theory provides important insight regarding the etiology of teen dating violence perpetration (TDV-P). Attachment insecurities have been associated with TDV-P, but the mechanisms underlying this association remain unclear. Furthermore, as of now, studies have failed to explore whether the relation between attachment insecurities and TDV-P varied according to its forms (i.e., psychological, physical or sexual) or to the perpetrator's gender. This study aimed to investigate if emotion dysregulation mediates the association between attachment insecurities and different forms of TDV-P among girls and boys. Adolescents (M age = 16 years; n = 3,214; 60% girls) were recruited from a one-stage stratified cluster sample of 34 high schools in Quebec, Canada. Path analyses with probit regression models were conducted separately for girls and boys. Attachment anxiety and avoidance were associated with more emotion dysregulation. Emotion dysregulation was, in turn, associated with higher probabilities of physical TDV-P in girls and psychological TDV-P in girls and boys. Surprisingly, emotion dysregulation was not associated with sexual TDV-P. Attachment anxiety remained directly related to higher probabilities of perpetrating all forms of TDV. These findings support the hypotheses set forth by attachment theory and highlight the utility of this theory to understand and potentially prevent TDV-P. Practitioners should more specifically address adolescents' attachment anxiety, as it seems more related to TDV-P. Finally, this study underscores the necessity of considering gender and specific forms of TDV-P to understand the association between attachment insecurities, emotion dysregulation, and TDV-P.

The purpose of this paper is to present the results of a study that draws upon a collaborative research strategy and has two main objectives: 1) Translating and adapting into French the Measure of Victim Empowerment Related to Safety (MOVERS scale) (Goodman et al. Psychology of Violence, 5(4), 355-366, 2015a); 2) Validating the French version of the MOVERS scale in a population of French-Canadian women receiving shelter services. The French-Canadian MOVERS (FCM) was administered to 189 women receiving shelter services in the province of Québec (Canada). The factorial structure, reliability and validity of the FCM were tested. This paper highlights that the FCM replicates the three dimensions found in the original version (Goodman et al. Psychology of Violence, 5(4), 355-366, 2015a), displays significant correlations with measures of depression, anxiety and stress, self-esteem, perceived social support, satisfaction with life and self-efficacy, and has overall good reliability estimates. The FCM is a valid and reliable scale to assess safety-related empowerment among women receiving shelter services. Furthermore, the scale provides interesting opportunities to shelter workers, which will be discussed in the paper. [ABSTRACT FROM AUTHOR]

Objective: Radiology residents must fulfill a standardized curriculum to complete residency and pass a certification exam before they are granted a licence to practice. We sought to evaluate how well residency prepares trainees for practice as perceived by recent graduates and their department chiefs. Subjects and Methods: Radiologists who graduated from the 4 Quebec radiology residency programs between 2005 and 2016 (n = 237) and Quebec radiology department chiefs (n = 98) were anonymously surveyed. Two electronic surveys were created, for recent graduates (74 questions) and for department chiefs (11 questions), with multiple-choice questions and open questions covering all fields of radiology. Surveys were administered between April and June 2016 using the Association des radiologistes du Québec database. Results: Response rate was 75 (31.6%) of 237 from recent graduates and 96% rated their training as excellent or good. Satisfaction with training in computed tomography and magnetic resonance imaging was high, with musculoskeletal (MSK) imaging, particularly MSK ultrasound (US), as well as pediatric, cardiac, and vascular imaging needing more training. Thirty-nine (39.8%) of 98 department chiefs answered the survey and highlighted weaknesses in the interpretation of conventional radiography, obstetrical US, and invasive procedures, as well as limited leadership and administrative skills. Recent graduates and department chiefs both reported difficulties in the ability to interpret daily volume of examinations as scheduled and invasive procedure competency. Conclusion: This survey highlights areas of the radiology curriculum which may benefit from more emphasis during training. Adjustments in the residency program would ensure graduates are successful both in their certification exams and clinical practice. [ABSTRACT FROM AUTHOR]

This article examines the legitimization and institutionalization of 'parental alienation' discourse in the Province of Quebec, Canada. It draws upon an analysis of 31 documents (legislation, research reports and articles, training documents, professional documents and media articles) and interviews with 13 key informants, who were selected based on their knowledge of 'parental alienation' in research, policies or practices. The research findings reveal that the legitimization and institutionalization of 'parental alienation' discourse is a more recent process than in other provinces and countries, but that it has now permeated child custody as well as child protection proceedings. Academic researchers and media have been instrumental in this legitimization and institutionalization process, while the role played by changes to child protection policies is more ambiguous. The findings reveal researchers' and experts' tendency to distance themselves from Gardner's controversial work on 'parental alienation syndrome' and to address the critiques by proposing new approaches and new concepts. However, the terms 'parental alienation syndrome', 'parental alienation' and 'alienating behaviours' are often used interchangeably, and assessment practices tend to rely on similar indicators.

Objectives: When the need for relatedness is frustrated, some older adults feel that life is not worth living and wish for death (WD). The aim of this study was to look at the perception of social interactions among older adults who express the WD. Methods: A probabilistic sample of 2787 French-speaking community-dwelling older adults aged 65 to 96 years (M = 73.8) took part in the Seniors Health Survey, a study on the prevalence of mental disorders which also collected information on various demographic and social variables. Results: Results showed that 5% of participants expressed WD. Participants who WD felt significantly more isolated and in conflict with their children than participants without WD. When sociodemographic variables, self-rated physical health, and depression were controlled, three social variables predicted WD in a logistic regression: being distant toward others, dissatisfaction with social life, and a lack of participation in organizations. Conclusions: Results of the present study support the interpersonal theory of suicide, which suggests that self-reported thwarted belongingness can foster WD. Clinical implications: Clinicians should consider social dissatisfaction and withdrawal as risk factors for WD and design interventions that foster social skills or meaningful connections.

This article describes our qualitative sociological study of immigrant children's life experiences of violence. We conducted interviews with 42 first‐generation immigrant children from any country, aged 9–13 years old, living in the Quebec City region (Canada). Results from three main themes are presented: representations of violence and concrete violent acts experienced; perceived effects of violence on children health and well‐being; and reactions and coping strategies. Overall, the narratives show that they may experience racist peer violence in school that leads to suffering situations, and they consequently have to develop strategies to maintain their well‐being. Social implications are discussed. [ABSTRACT FROM AUTHOR]

Aim To document perceptions of circumstances spontaneously associated with the occurrence of the stroke on that particular day. Background Known triggers of stroke include birthday or negative emotions. However, specific circumstances relating to that birthday or emotion have not yet been documented. Design Phenomenological perspective where data were collected between October 2011-June 2012. Method In-depth interviews conducted 5-8 weeks post stroke with 37 participants, with a mean age of 56·3 years ( sd 11·9) and 40·5% (14/37) of whom were female. An interview guide composed of open-ended questions and developed with experts was used to explore in detail free associations surrounding the stroke. All interviews were audiotaped and transcribed. Data were rigorously analysed by two team members and discussed in team meetings until reaching consensus on essential themes. Findings Relationships emerged as being the overarching theme related to stroke triggers with the interrelated subthemes of: (1) birthday or anniversary; (2) parenting; (3) being sick seen as a benefit; and (4) alcohol or drug abuse. The stroke happened on a day which was related in some way to a relationship with a significant other affected by tension, a lack of transparency or an overinvestment of emotional/affective state. Conclusions There is a need to address individuals' beliefs as a part of secondary prevention interventions to be truly client-centred, which the phenomenological perspective allows. Relationships as a potential source of stress should be added as a theme to discuss with patients for a holistic approach to stroke prevention including psychosocial factors. [ABSTRACT FROM AUTHOR]

This paper introduces the problem of scheduling emergency room physicians. We interviewed physicians from six hospitals in the greater Montreal, Canada area, in order to understand the emergency room scheduling problem. Extracting the real scheduling problem is difficult because physician working conditions are based on informal mutual cooperation which is usually not documented. We present the characteristics of the scheduling problem and the scheduling techniques currently used in the six emergency rooms we analyzed. Using the scheduling problems of Charles-Lemoyne Hospital and the Jewish General Hospital, we show how to modify a hospital's existing scheduling rules to develop techniques which produce better schedules and reduce the time needed to build them.

Background: The role of metabolic syndrome (MetS) in prostate cancer risk is still debated. We investigated it in a large population-based case-control study.Methods: Cases were 1937 men with incident prostate cancer, aged ≤ 75 years, diagnosed across French hospitals in the Montreal area between 2005 and 2009. Concurrently, 1995 population controls from the same residential area and age distribution were randomly selected from electoral list of French-speaking men. Detailed lifestyle and medical histories, and anthropometric measures, were collected during in-person interviews. Prevalence of MetS components (type 2 diabetes, high blood pressure, dyslipidemia and abdominal obesity) was estimated at 2 years before diagnosis for cases/ interview for controls, and at ages 20, 40, 50 and 60. Logistic regression was used to estimate odds ratios (OR) and 95 % confidence intervals for the association between MetS and prostate cancer risk.Results: A history of MetS (≥ 3 components vs < 3) was associated with a reduced risk of prostate cancer (OR = 0.70 [0.60, 0.82]) after considering potential confounders. The negative association was particularly pronounced with a young age (≤ 40 years) at MetS onset (OR = 0.38 [0.16-0.89]), did not vary according to prostate cancer aggressiveness, and was only partly explained by the presence of type 2 diabetes. A risk decrease was observed with the number of MetS components, suggesting a synergistic interaction of the components.Discussion: The observed negative association, consistent with results from other North American populations undergoing regular prostate cancer screening, underlines the importance of considering PSA-testing when studying the MetS-prostate cancer association.Conclusions: Findings from this study are consistent with an inverse association between MetS and prostate cancer risk.

Numerous studies have shown that cohabitors are less likely to pool their money than married couples. The authors raise the question of whether the marriage-cohabitation gap in money pooling varies according to the level of institutionalization of cohabitation in the society. They compared 2 Canadian regions with very different demographic regimes. The francophone province Québec has the highest proportion of cohabiting couples in the world, whereas the levels of cohabitation are moderate in other Canadian provinces. Moreover, the 2 regions differ in their legal systems (civil code vs. common law) and legal regulation of cohabitation. Using data from the Canadian 2011 General Social Survey ( N = 9,852), the authors found that cohabitors in both regions are less likely to pool their money together. Nevertheless, they did not confirm the hypothesis that the marriage-cohabitation gap is smaller in Québec despite the higher levels of institutionalization of cohabitation in this region.

Boreal rivers and streams are known as hot spots of CO2 emissions, yet their contribution to CH4 emissions has traditionally been assumed to be negligible, due to the spatially fragmented data and lack of regional studies addressing both gases simultaneously. Here we explore the regional patterns in river CO2 and CH4 concentrations ( pCO2 and pCH4), gas exchange coefficient ( k), and the resulting emissions in a lowland boreal region of Northern Québec. Rivers and streams were systematically supersaturated in both gases, with both pCO2 and pCH4 declining along the river continuum. The k was on average low and increased with stream order, consistent with the hydrology of this flat landscape. The smallest streams (order 1), which represent < 20% of the total river surface, contributed over 35% of the total fluvial greenhouse gas (GHG) emissions. The end of winter and the spring thaw periods, which are rarely included in annual emission budgets, contributed on average 21% of the annual GHG emissions. As a whole, the fluvial network acted as significant source of both CO2 and CH4, releasing on average 1.5 tons of C (CO2 eq) yr−1 km−2 of landscape, of which CH4 emissions contributed approximately 34%. We estimate that fluvial CH4 emissions represent 41% of the regional aquatic (lakes, reservoirs, and rivers) CH4 emissions, despite the relatively small riverine surface (4.3% of the total aquatic surface). We conclude that these fluvial networks in boreal lowlands play a disproportionately large role as hot spots for CO2 and more unexpectedly for CH4 emissions. [ABSTRACT FROM AUTHOR]

Primary objective: This study investigated clinicians' perceptions on factors linked to patient complexity in traumatic brain injury (TBI) outpatient rehabilitation. Method: Twelve clinicians from various disciplines, working in TBI outpatient programmes from three rehabilitation institutions in Montreal, Quebec, were recruited using convenience and snowball sampling. Data was collected through focus groups and individual interviews and thematic analysis was used to identify themes. Main outcomes and results: Participants identified complexity factors falling under the following themes: sequelae of TBI (cognitive/behavioural/psychological impacts), personal factors (personality traits, pre-medical state, lifestyle and age), patients' environment (architectural, social, language, cultural and financial) and therapeutic relationship (mismatch, misunderstanding and personality clashes). Clinicians also reported facilitators to optimal treatment delivery such as quality of services and working in an interdisciplinary team. Limited time, training and resources were identified as barriers to treatment. Conclusion: A substantial proportion of patients in outpatient TBI programmes seem to follow an atypical evolution and exhibit added complexity. In order to optimize quality of care, clinicians recommended increased community awareness about TBI, increased resources for rehabilitation clinicians and specialized services post-discharge. These findings are insightful for stakeholders; providing a basis for discussions on policy changes that can better meet this population's needs. [ABSTRACT FROM AUTHOR]

Anosognosia, or unawareness of one's own cognitive deficits, may cause issues when measuring perceived stress and cortisol levels in Alzheimer's disease (AD) and Mild Cognitive Impairment (MCI). The goal of this study was to examine the effects of anosognosia on perceived stress and salivary cortisol levels in normal elderly (NE) adults, MCI individuals, newly diagnosed AD patients, and long-lasting AD patients, suspected to show more anosognosia. An anosognosia index for perceived stress was computed by subtracting the score on the Perceived Stress Scale measured in the participants and their relative. Cortisol levels were measured four times a day over two nonconsecutive days. Greater anosognosia for dementia correlated with greater anosognosia for perceived stress in the group as a whole. However, no correlation between cortisol levels and either anosognosia for dementia or perceived stress was observed.Our results suggest that measuring perceived stress in AD patients may be influenced by anosognosia.

This article presents findings from a study that investigated child protection policies and practices, and focuses on data gathered in a child protection agency located in Quebec, Canada. This research project draws upon a qualitative case-study methodology, involving a documentary analysis of both national and local child protection policies, as well as semi-structured individual interviews with child protection front-line workers and front-line managers, managers and reviewing officers. Although the dominant pattern that emerged in the data suggests that child protection workers tend to focus on abused women's actions and to blame them for “failing to protect” their children, this article emphasises practices where the research participants had managed to avoid mother-blaming when working with these women. Indeed, the findings suggest that child protection workers can avoid mother-blaming when working with abused women, despite shortfalls in policies, procedures and resources. Such practices include recognising that there are two victims in domestic violence situations, building a trusting relationship, providing emotional and practical support, and balancing risk and safety. These four dimensions are interrelated and they all require a clear identification of domestic violence, as well as a good understanding of the problem and its impacts. To emphasise individual workers’ positive practices with women in domestic violence situations should not be used to minimise the importance of more structural changes in child protection policies and practices. This would include challenging the tendency to focus on women and finding more effective ways to engage with abusive men throughout child protection procedures in order to challenge their violent behaviours. However, it could lead to an approach that is more sensitive to domestic violence and that has the potential to alleviate the workers’ feelings of powerlessness and frustration in relation to their work with families where there has been domestic violence.

Research on a captive harbor seal (Phoca vitulina) mother-pup pair showed that ingestion of milk caused a decrease in stomach temperature (Hedd et al., 1995). Herein the feasibility of stomach temperature telemetry for measuring nursing behavior was tested in wild harbor seal pups from the St. Lawrence River Estuary. Fifteen pups were outfitted with time-depth recorders, stomach temperature transmitters (STT), and stomach temperature recorders in 2002 and 2003. Twelve pups were recaptured, and seven yielded usable stomach temperature data. Excluding a mortality that lost its transmitter the day of release, transmitter retention time ranged from at least 7 to 22 d (12.5 ± 1.45 d) based on a STT signal at recapture. Pups that gained more weight had a higher frequency of decreases in stomach temperature (DST) (R2 = 0.954, p < 0.001). Depth and external temperature data showed that most DST occurred while pups were "in the water" (57%) followed by "just before or after hauling out" (19%), "just before or after entering the water" (15%), and "hauled out" (9%) (χ2 = 56.376, p < 0.001). The frequency DST did not change with age, and there was no diel pattern of DST, which also did not change with age. These findings indicate that transmitter retention times are sufficient to monitor most of the nursing period for harbor seals, that stomach temperature can be used to quantify nursing characteristics in the field, and that a telemetric technique is needed for harbor seals as most nursing events occur in the water.

Winter ice cover is a fundamental feature of north temperate aquatic systems and is associated with the least productive months of the year. Here we describe a previously unknown freshwater habitat for algal and microbial communities in the ice cover of the freshwater St. Lawrence River, Quebec, Canada. Sampling performed during winter 2005 revealed the presence of viable algal cells, such as Aulacoseira islandica (O. Müll.) Simonsen (Bacillariophyceae), and microbial assemblage growing in the ice and at the ice–water interface. Vertical channels (1–5 mm wide) containing algae were also observed. Concentrations of chl a ranged between 0.5 and 169 μg · L−1 of melted ice, with maximal concentrations found in the lower part of the ice cores. These algae have the potential to survive when ice breakup occurs and reproduce rapidly in spring/summer conditions. Freshwater ice algae can thus contribute to in situ primary production, biodiversity, and annual carbon budget in various habitats of riverine communities. [ABSTRACT FROM AUTHOR]

Purpose – Aims to examine the influence exerted by two key actors – sales person and sales manager – on the salesforce control system used by high-tech industries. First, since these industries evolve in a highly turbulent environment, external conditions can be expected to modify the relationships between the antecedents and the control system. Also seeks to study the differences in two industries' reactions to an uncertain environment. Design/methodology/approach – The investigation was empirical, and a total of 200 managers were surveyed across two industries (the computer and the electrical/electronic industries) in the province of Quebec, Canada. Findings – Results suggest that both sales person and sales manager characteristics predict the control system. Second, environment uncertainty and technological turbulence modify the relationships between most of the antecedents and the control system. Third, few differences were found in how the two industries respond to a turbulent environment. The results cannot be generalized, mainly because of the geographical context of this research, meaning that their use is somewhat limited for managers in other regions. The findings nonetheless give managers insight into which characteristics influence the control system and how environment influences the relationships investigated. Originality/value – Contributes to the marketing literature since it is the only study other than Krafft's that measures the direct effects that the two key actors exert on the control system. This research is also the first to empirically show the indirect effects attributable to environment. The results are exploratory and should be replicated in other contexts to improve their external validity. [ABSTRACT FROM AUTHOR]

This paper presents a benchmarking study carried out on the supply departments of Quebec's health services. The paper begins with the definition of a methodology to collect the information needed, both environmental (to enable institutions to be sorted into homogenous groups) and performance related. The analysis of indicators and the data envelopment analysis (DEA) models allowed classification of each hospital's performance and explained the operational approaches used, either at a general level or for each subprocess of the supply chain. It was observed that important economies of scale may be achieved with better co-ordination and with the regrouping of the supplying activities, both for purchasing management and central store management. The study showed that the best performance of central store services comes with flexible administrative structures, by receiving packages as small as possible and by using employees from the lowest range of the hierarchy. Purchasing services should employ highly qualified and well-paid staff. Although such services are relatively small with respect to their purchase volume, they show a higher activity rate. As a result of the discovered performing strategies, the possible economies range from 20% to 30% of the actual supply-chain management cost. [ABSTRACT FROM AUTHOR]

This article describes a districting study undertaken for the Côte-des-Neiges local community health clinic in Montreal. A territory must be partitioned into six districts by suitably grouping territorial basic units. Five districting criteria must be respected: indivisibility of basic units, respect for borough boundaries, connectivity, visiting personnel mobility, and workload equilibrium. The last two criteria are combined into a single objective function and the problem is solved by means of a tabu search technique that iteratively moves a basic unit to ah adjacent district or swaps two basic units between adjacent districts. The problem was solved and the clinic management confirmed its satisfaction after a 2 year implementation period. [ABSTRACT FROM AUTHOR]

Background: Adolescents in a dating relationship can interact anytime using information and communication technologies. Yet, despite associated potential benefits, this availability of means to reach out to their partner may also exacerbate possible conflictual exchanges, including dating violence through technology. This study aimed to document the prevalence of cyber dating violence (CDV) victimization and perpetration among teenagers. It also explored self-esteem and psychological distress in participants having been perpetrators, victims, or perpetrator-victims, compared with those not having experienced CDV.Methods: The sample comprised 190 teenagers from a small urban area who completed the K10 psychological distress scale, the Self-Description Questionnaire, which measures self-esteem, and the Cyber Dating Abuse Questionnaire, which measures the prevalence of CDV victimization and perpetration.Results: Our results suggest no gender difference in the prevalence of CDV victimization (35.8%), perpetration (33.0%), or the high co-occurrence rate of victimization and perpetration (27.2%) in the last 12 months. When age and gender were controlled for, cyber dating violence was found to be associated with low self-esteem and psychological distress in teenagers. Cyberperpetration was also associated with higher self-esteem.Limitations: The cross-sectional design precludes any conclusion about the sequencing of the variables. Reliance on a convenience sample also represents a limitation of the study.Conclusions: CDV is associated with low self-esteem and psychological distress in teenagers. Dating violence prevention programs should include issues related to CDV, considering its high prevalence, conceptual proximity to psychological violence, and relationship with psychological distress and low self esteem.

Coastal rivers represent an important flux of mercury (Hg) to marine systems, but large uncertainties remain due to a lack of field data in key regions of the northern hemisphere. Given the increasing number of dams built on rivers globally and their influence on the Hg cycle, damming may affect broad-scale Hg budgets, but empirical studies on the contribution of dammed vs undammed rivers on fluxes at broad spatial extents remain scarce. Here we have compiled measurements of the concentrations, fluxes and yields of Hg, methylmercury (MeHg), dissolved organic carbon (DOC) concentration and quality at the mouth of 9 dammed and 21 undammed coastal rivers across Quebec, Eastern Canada. Total and methyl Hg concentrations were typically lower for dammed vs. undammed rivers (mean Hg of 1.40 vs. 2.79 ng L−1; mean MeHg of 0.10 vs. 0.13 ng L−1). The yields displayed the same pattern (mean Hg of 0.82 vs. 1.50 g km−2 year−1; mean MeHg of 0.05 vs. 0.07 g km−2 year−1) although dammed river fluxes were typically higher (mean Hg of 25.66 vs. 15.02 kg year−1; mean MeHg of 1.25 vs. 0.48 kg year−1) because of higher discharge. DOC fluxes were good predictors of Hg fluxes and could be used as proxies. We extrapolated these fluxes to the entire province of Quebec and provide a first order estimate of annual Hg flux of 454 ± 72 kg from dammed and of 1879 ± 240 kg from undammed rivers, compared to 33 ± 5 kg and 89 ± 11 kg of MeHg, respectively. These findings are in the lower range of current estimates for other northern regions and suggest that dammed rivers export mercury in amounts that are roughly proportional to river discharge. [Display omitted] • Hg and MeHg fluxes from Quebec rivers to marine systems were studied. • Concentrations and yields of Hg were lower in dammed vs. undammed rivers. • Dissolved organic carbon fluxes were good predictors of mercury fluxes. • Overall, Quebec rivers export 2333 and 122 kg of Hg and MeHg annually.
