Urban horticulture poses a sustainable form of food production, fosters community engagement and mitigates the impacts of climate change on cities. Yet, it can also be tied to health challenges related to soil contamination. This work builds on a previous study conducted on eleven urban gardens in the city of Vienna, Austria. Following the findings of elevated Pb levels in some soil and plant samples within that project, the present study investigates the elemental composition of soil and plants from two affected gardens 1 year after compost amendment. Inductively coupled plasma mass spectrometry (ICP-MS) analysis of skin, pulp and seeds of tomato fruits revealed minor variations in elemental composition which are unlikely to have an impact on food safety. In turn, a tendency of contaminant accumulation in root tips and leaves of radishes was found. Washing of lettuce led to a significant reduction in the contents of potentially toxic elements such as Be, Al, V, Ni, Ga and Tl, underscoring the significance of washing garden products before consumption. Furthermore, compost amendments led to promising results, with reduced Zn, Cd and Pb levels in radish bulbs. Pb isotope ratios in soil and spinach leaf samples taken in the previous study were assessed by multi-collector (MC-) ICP-MS to trace Pb uptake from soils into food. A direct linkage between the Pb isotopic signatures in soil and those in spinach leaves was observed, underscoring their effectiveness as tracers of Pb sources in the environment., (© 2024.

The COVID-19 pandemic has dramatically impacted human lifestyles across the world. Lockdowns and home confinement decreased prior opportunities for everyday physical activity. To retrospectively assess how the Austrian population coped with these aspects of the crisis, we conducted a cross-sectional online survey from March to September 2021 using a structured questionnaire in German. In total, 1214 participants (56.9% females, mean age 37.0 years) living across Austria shared self-reported information on sociodemographic characteristics, indoor and outdoor physical activity, reasons for being outdoors, and life satisfaction before and after the emergence of the virus. As a result, overall indoor physical activity significantly decreased in a before-during COVID-19 crisis comparison, although exercising at home with online instructions increased by about 63%. Exercising outdoors increased overall, specifically in periurban forests and rural areas, both by about 9%. Life satisfaction decreased significantly by 19.7% ( p < 0.001). Outdoor public places and natural environments gained importance due to restrictions affecting access to sport facilities. Further research is needed to evaluate benefits and therapeutic values of outdoor nature for physical and mental health in times of a global pandemic to maintain resilient societies, as it might impact future active living and life satisfaction.

Digitalized healthcare services offer remote and cost-effective treatment of diabetes patients. Thus, the present online study analyzed the readiness to use telemonitoring among Austrian diabetes patients. We developed and validated a German version of the patient telehealth readiness assessment tool and performed quantitative context analysis of free-text comments on perceived barriers and benefits of telemonitoring. Participants (n = 41, 42.6% females) achieved a medium average readiness level for telemonitoring. The three top benefits were intensified care, shorter travel and waiting times, and better therapy adjustment. The top three barriers were data privacy issues, loss of personal communication and focus on blood sugar, and teledoctor competence. Diabetes patients represent a suitable target group for remote treatment opportunities. However, a shift from traditional face-to-face medical care to exclusive telemonitoring treatment from diagnosis to consultation and treatment requires fundamental new legal framework conditions.

Physicians increasingly use medical applications to facilitate clinical information management. The respective effect on clinical communication and quality of healthcare provision has not been studied in the Austrian context so far. Thus, the current cross-sectional online study analyzed prevalent medical applications use and views on clinical communication competence in everyday medical practice among Austrian physicians (n = 151) and validated the survey tool. More than half of the participants used medical applications in daily clinical practice. The top three benefits of medical applications use were higher quality of healthcare, location-independent health service access, and higher efficiency in healthcare resource allocation. Moreover, study participants felt that communication competence acquired during medical studies inadequately prepared them for daily clinical practices. Medical applications use certainly affects the therapeutic alliance between patients and physician. This study supports the importance of initiating an open, constructive discussion among healthcare stakeholders and developing according to evidence-based guidelines.

In today's digitalized world, most parents are Internet-savvy and use online sources for child health information, mainly due to the 24/7 availability of advice. However, parents are often not specifically trained to identify reliable, evidence-based sources of information. In this cross-sectional online survey among a purposive, non-probabilistic sample of Austrian parents ( n = 90, 81.1% females), we assessed aspects of health app use and family policy benefits-related and scenario-based Internet seeking behavior. We found that the surveyed parents showed a high health app use. The participants indicated that they prefer online information seeking to any other option in a scenario describing that their child would be sick at after-work hours, with social media channels being the least preferred source of online information. Mothers and younger parents were more likely to retrieve online information on family policy benefits. With the smartphone in everybody's pocket, parents seemed to rely on mobile and online content when searching for child health information. Pediatricians are best suited to decide what treatment fits the child or their current medical condition, but nowadays they face increasing numbers of pre-informed parents seeking health information online. Provision of targeted parental education and guidance through the online information jungle could effectively empower parents and smooth personal and digital contacts in the delicate doctor-parent-child triangle.

Prior research shows that forests contribute to human health and well-being. In this sense, this cross-sectional case study, adopting the principles of citizen science, assessed the restorative potential of places in the Hallerwald, an Austrian community forest. A convenience sample of adult forest visitors (n = 99, 64% females) completed a survey during a guided 2.5 h forest tour. The German questionnaire assessed the qualities of defined places in the forest. We also investigated changes in mood states, perceived stress, restoration, connectedness, and mindfulness before and after visiting the forest. In cooperation with a local working group, we developed the new Widen One's Mind (WOM) scale, which showed good scale characteristics. All places received high scores in their potential to increase restoration and vitality and to widen one's mind. Positive affect, restoration, connectedness with nature and the forest, and mindfulness increased pre- versus post-visits, whereas negative affect and perceived stress decreased. The findings of this study suggest that in recreational forests, visitors experience beneficial mental effects such as stress reduction in addition to physical exercise. To facilitate regional development goals, we recommend evaluating places in forests regarding the potential effects on the health and well-being as well as citizen participation before initiating extensive remodeling.

With the emergence of an always-on culture and the private smartphones always within reach, professional and recreational contexts overlap. Little empirical knowledge is available on prevailing online habits among healthcare personnel and whether gender matters in this context. To investigate health technology-related preferences, we conducted an online survey among a purposive sample of employees and students at the Medical University of Vienna, Austria. In total, 905 participants (59.0%, 540/905, females) provided self-reported information on use of online services and mobile health applications (apps) as well as respective gender-specific internal and external apperceptions. Mann-Whitney U tests and binary regression analysis assessed respective gender differences. The structured German questionnaire was validated by principal component analysis. The study found a moderate familiarity with health technologies. As for gender differences, prevailing health app use was high among both male and female participants (39, 141/365, and 42%, 229/540, respectively), with apps for tracking activity and nutrition habits most commonly used. Approval for monitoring health and lifestyle parameters, eHealth and telemedicine knowledge levels, and online health information retrieval predicted health app use, whereas gender did not. Socio-demographic attributes including gender influence not only private online habits of users, but might also affect acceptance of health technologies and their professional use in a clinical setting. Thus, addressing the gender dimension already in concept stages of digital devices and services for healthcare and lifestyle could speed up private and public adoption of health technologies., (Copyright © 2019 Elsevier B.V.

Background: As part of the mobile revolution, smartphone-based applications (apps) have become almost indispensable in today's information society. Consequently, the use of medical apps among healthcare professionals has increased heavily over the past years. As little is known on medical app use in day-to-day clinical practice in Austria, the present study aims at closing this knowledge gap by assessing respective prevalence, readiness, and concerns among Austrian practitioners., Methods: We conducted a cross-sectional online survey among a sample of 151 Austrian doctors (mean age 45.0, SD 12.0, 55.0% females). We developed a German study questionnaire on the basis of the Practitioner Telehealth Readiness Assessment Tool (PRAT) to assess medical app use-related readiness and attitudes, and validated it using principal component analysis., Results: In our study, 74% of participants used medical apps on a daily basis, with clarity, ease of use, speed, and support in clinical routine mentioned as most important app features. However, the majority of participants perceived certain barriers to use medical apps. Younger participants used more medical apps, were more likely to use them during work, and yielded higher readiness scores. The most often used medical apps were Diagnosia and Embryotox (both 28.5%)., Conclusions: Nowadays, medical apps serve as an important source of information for many doctors and are especially popular among younger physicians. The omnipresence of smartphones in the smocks of healthcare workers raised awareness for potential shortcomings regarding disruption of traditional face-to-face doctor-patient interaction among all healthcare stakeholders. This study's finding thus highlight the need for initiating a public discussion on legal and social frameworks to successfully integrate mobile apps into everyday clinical.

Technological advances toward consumer-specific expectations require a sustained commitment and coordination across policy- and decision-makers. The present scenario-based study aimed at identifying prevailing perceptions regarding telehealth applications among Austrian healthcare experts. During a two-round online Delphi survey, panelists rated perceived benefits, obstacles, innovativeness, desirability, and estimated implementation date of 10 telehealth scenarios. Panelists (n = 73, 74% males) perceived that the implementation of telehealth scenarios could especially improve patients' knowledge, quality of social healthcare, and living standard. In contrast, the three top-ranked obstacles were costs, technical prerequisites, and data security. Survey participants rated innovativeness of the presented future scenarios as quite high, whereas perceived desirability was moderate. Overall, ratings suggested precautious attitudes toward technological innovations. The survey findings suggest building taskforces and enhancing communication between healthcare stakeholders to proactively shape the future of telehealth in Austria.

Digitalization affects almost every aspect of modern daily life including healthcare delivery. Successful adoption and sustainable integration of information technology-based eHealth and telemedicine concepts in clinical practice depend on constant evaluation of end user needs, proficiencies, and preferences. We therefore assessed how current and future healthcare professionals perceived health technology solutions and whether their perceptions differed. We conducted an online survey among a purposive sample of employees and students at the Medical University of Vienna, Austria. The structured questionnaire collected self-reported practices and beliefs in the context of eHealth and telemedicine among 905 participants (59.0% females), of which 48.4% were employees and 51.6% were students. Participants expressed moderate knowledge of eHealth and telemedicine concepts with higher levels among employees compared to students (both: p<0.05). Compared to employees, students were less convinced that online health information improves patient knowledge (p<0.001), but were more optimistic that telemedicine reduces healthcare costs (p<0.05). Participants doubted that telemedicine services would enhance the doctor-patient relationship and raised concerns regarding data security and privacy issues. Accordingly, quantitative context analysis of free text comments revealed that the four most frequently mentioned themes were related to issues concerning data privacy and security, questions of responsibility, doctor-patient interaction, and reliability of information. This study provides valuable insights into how current and future healthcare professionals differ in their perceptions regarding eHealth and telemedicine. These findings raise awareness of the need to bridge the gap between digital age groups and professional groups, especially in clinical healthcare delivery in a clocked-through, strenuous academic setting as found at a medical university., Competing Interests: The authors have declared that no competing interests exist.

Background: Telemonitoring services could dramatically improve the care of diabetes patients by enhancing their quality of life while decreasing healthcare expenditures. However, the potential for implementing innovative treatment options in the Austrian public and private health system is not known yet. Thus, we analyzed the readiness to use telemonitoring in diabetes care among Austrian practitioners., Methods: We conducted an online survey among a purposive sample of Austrian practitioners (n = 41) using an adapted German version of the practitioner telehealth readiness assessment tool. We assessed three readiness domains for telemonitoring in the context of diabetes care, i.e. core readiness, engagement readiness, and structural readiness, and validated the German tool using principal components analysis., Results: Study subjects perceived themselves as open to innovations and also expressed optimistic attitudes towards telemonitoring in general and offering telemonitoring-based services for their patients. Participants achieved a medium average readiness level for telemonitoring (58.2, 95% CI 53.9-62.5) and were thus in a good position to use telemonitoring, although some arguments may adversely affected its use. The top three perceived benefits of telemonitoring were enhanced quality of treatment, better therapy adjustment, and reduced travel and waiting times for patients. The top three barriers were reduced personal communication, practitioner time expenditure and equally placed poor financial compensation as well as data security and privacy issues., Conclusion: Our data revealed that Austrian practitioners showed a quite moderate readiness to use telemonitoring in diabetes care. To further advance telemonitoring readiness among all pillars of diabetes care in Austria, joint efforts among healthcare stakeholders are required to overcome existing financial, organizational, and technical obstacles.

Aim: To explore how nurses recover from night shift work during periods off duty., Background: Given the large number of affected individuals globally, detrimental health outcomes of night shift work are an important public health issue. Sufficient recovery opportunities are essential to prevent prolonged fatigue associated with demanding tasks and high workload as experienced in nurses working long shifts during the night., Method: Nurses (n = 53, 96% females) who worked in two public nursing homes in Austria completed a 5-day diary to collect data on well-being conceptualized by fatigue, distress and vigour., Results: Nurses experienced worse well-being post night shift days than during rest days. Well-being improved from post night shift day 2 to the following rest day 1 and continued improvement from rest day 1 to rest day 2., Conclusions: Nurses who work at nights are at risk for experiencing prolonged fatigue. Our results suggest that after two consecutive 12-hr night shifts full recovery needs at least three days off work., Implications for Nursing Management: Strategies for maintaining nurses' good health and caring attitudes as well as vigilance for patient safety should include fatigue management plans and optimised schedules for night shift work., (© 2018 The Authors.

New technological developments affect almost every sector of our daily lives including the healthcare sector. Successful adoption and sustainable integration of eHealth and telemedicine in Public Health strategies (also known as Public eHealth) depend on knowledge and constant evaluation of consumers' needs, proficiencies, and preferences. We therefore assessed how the general Austrian population perceived innovative Public eHealth solutions. The online survey on 562 Austrian adults (58.9% females) collected self-reported data on current and expected use of smartphone-based health applications (apps) of digital natives (35 years and younger) and digital immigrants (aged 35+). In total, 26.7% (95% CI 23.0-30.4) of participants already used health apps, especially lifestyle-associated apps for monitoring exercise habits and nutritional habits. We found substantial digital age group differences; compared to digital immigrants digital natives were more likely to use mobile devices and health apps. Health apps have the potential to improve community health and prevent lifestyle diseases cost-effectively and efficiently, and thus build an important pillar of Public eHealth. With regard to aging societies, healthcare providers could take advantage of consumer-oriented health apps by assessing individual needs of specific target groups such as elderly people.

Recreational sun exposure accounts for a large number of acute and chronic dermatological diseases, including skin cancer. This study aimed at estimating the one-year prevalence of sun exposure and skin health-associated knowledge and attitudes among Austrian citizens. The population-based UVSkinRisk survey investigated a representative sample of Austrian adults using a structured questionnaire. In total, 1500 study subjects (median age 33.0 years, 50.5% females) participated in this questionnaire survey. Among study participants, prevalence of sun exposure was 47%, with slightly higher rates in males (48%) compared to females (46%). Younger age, lower professional category, darker skin type, motives to tan, sunbed use, sunburn, and outdoor sport activity increased the odds for prevalent sun exposure. This is the first population-based study evaluating the prevailing sun exposure and recreational habits influencing skin health among Austrian citizens. Despite public media campaigns educating on the harmful effects of sunlight exposure, we found a high prevalence of self-reported sunlight exposure. The results suggest that multifaceted socio-cultural characteristics stimulate recreational sun exposure and tanning habits. Communicating individualized Public (Skin) Health messages might be the key to prevent photo-induced skin health hazards in light-skinned populations. The practical and theoretical implications of these findings are discussed.

Background: Life-style-associated exposure to sunlight is a contributory factor for acute and chronic skin damage including malign melanoma. The aim of the present study was to investigate the current gender-specific attitudes and motives regarding sun tanning and sunlight protective behaviour among Austrian residents., Methods: In this cross-sectional study, a convenient sample of 563 Austrian inhabitants participated in a self-reported questionnaire-based outdoor survey. We subjected the data obtained to statistical analysis to get insight into socio-demographic and sun risk behaviour-related inter-group differences (smoking habits as well as gender)., Results: The survey revealed significant gender differences in respect to sun protective behaviour and knowledge on adverse health effects of ultraviolet light exposure. Female participants achieved a higher knowledge score, showed higher risk awareness, and performed more sun protection (all p < 0.0001). Male participants were more likely to underestimate the dangers of unprotected sun exposure, consistently resulting in a higher frequency of reported sunburns in men (p = 0.005). Although smoking habits were gender-independent, smokers compared with non-smokers sun bathed more frequently with less sun protection (all p < 0.0001), and were less sportive (p = 0.035)., Conclusions: The study provides empirical data contributing to the development of novel approaches for target group and gender-specific Public (Skin) Health education programs and information materials. Revised strategies for improved skin health promotion and skin cancer prevention should focus on the benefits of sun light avoidance regarding long-term deterioration of physical appearance and attractiveness.

Objectives: The current digital revolution is particularly relevant for interactions of healthcare providers with patients and the community as a whole. The growing public acceptance and distribution of new communication tools such as smart mobile phones provide the prerequisite for information and communication technology (ICT) -assisted healthcare applications. The present study aimed at identifying specifications and perceptions of different interest groups regarding future demands of ICT-supported doctor-patient communication in Austria., Methods: German-speaking Austrian healthcare experts (n = 73; 74 percent males; mean age, 43.9 years; SD 9.4) representing medical professionals, patient advocates, and administrative personnel participated in a 2-round online Delphi process. Participants evaluated scenario-based benefits and obstacles for possible prospect introduction as well as degree of innovation, desirability, and estimated implementation dates of two medical care-related future set ups., Results: Panelists expected the future ICT-supported doctor-patient dialogue to especially improve the three factors doctors-patient relationship, patients' knowledge, and quality of social health care. However, lack of acceptance by doctors, data security, and monetary aspects were considered as the three most relevant barriers for ICT implementation. Furthermore, inter-group comparison regarding desirability of future scenarios showed that medical professionals tended to be more skeptical about health-related technological innovations (p < .001)., Conclusions: The findings of this survey revealed different expectations among interest groups. Thus, we suggest building taskforces and using workshops for establishing a dialogue between stakeholders to positively shape the future of ICT-supported collaboration and communication between doctors and patients.

Connectedness to nature (CN) influences motivation to have contact with outdoor natural environments. Spending leisure time in natural environments is beneficial for human health and well-being. Besides these positive effects, health risks of open-air activities are mainly related to unprotected sun light exposure-associated acute and chronic skin hazards. Thus, we conducted a cross-sectional, representative telephone survey among Austrian residents to study the association of perceived CN level with sun-exposure knowledge, tanning habits, and sun protective behaviour. In total, 1,500 study subjects (50.5% females) participated in this questionnaire survey. Although knowledge about tanning and motives to tan were similar among genders, females performed more photoprotective measures and were more connected to nature (all p < 0.001) compared to males. Older age and outdoor sport were significant gender-independent predictor variables influencing perceived CN level. Additionally, level of education was relevant in male CN, whereas non-smoking and higher knowledge were predictive of female CN. This survey provides so far unreported empirical data on the relationship between nature connectedness and skin health-relevant recreational habits of Austrian residents. The findings suggest to integrate hitherto neglected gender-specific Public (Skin) Health promotion when counselling on the manifold health advantages of outdoor activities.

Annual solar ultraviolet radiation (UVR) is mostly determined by latitude and altitude. Over the last decades, increasing UVR ground levels have been observed. Exposure to UVR is associated with a life-time risk to develop melanoma, a malign skin cancer. Thus, we hypothesized that melanoma incidence in Austria is associated with altitude of place of living and time of diagnosis. We investigated this hypothesis in an ecological study by district and year for Austrian melanoma incidence (1990-2010) and mortality (1970-2011) data. As expected, incidence rates increased with altitude (about 2% per 10 m) and year (about 2%). Additionally, melanoma incidence rates were about 50% higher in urban than in rural districts. In contrast, mortality rates decreased with altitude (for males: 0.4% per 10 m, for women: 0.7% per 10 m, respectively). The observed discrepancy between incidence and mortality data could partly be explained by melanoma diagnosis at earlier tumor stage in districts with higher altitude. Possible reasons for this finding include higher awareness of patients, better diagnostic performance of medical professionals working at higher altitudes, or slower tumor growth due to protective effects of sun light-associated vitamin D synthesis.

Objectives: WHO's Children's Environment and Health Action Plan for Europe (CEHAPE) focuses on improvements of indoor environments where children spend most of their time. To investigate the relationship between school indoor air pollutants and cognitive performance in elementary school children, a multidisciplinary study was planned in all-day schools in Austria., Materials and Methods: In a cross-sectional study (LuKi study: Air and Children) indoor air pollutants were monitored in nine elementary all-day schools in urban and rural regions of Austria. In addition, school dust and suspended particulates (PM10, PM2.5) were measured, focusing on semivolatile compounds (e.g. phthalates, phosphororganic compounds [POC]). Health status and environmental conditions were determined by parents' questionnaire, cognitive function was measured by Standard Progressive Matrices (SPM)., Results: Overall, 596 children (6-8 years of age) were eligible for the study. Cognitive tests were performed in 436 children. Analysis showed significant correlations of tris(2-chlorethyl)-phosphate (TCEP) in PM10 and PM2.5 and school dust samples with cognitive performance. Cognitive performance decreased with increasing concentrations of TCEP. Furthermore, cognitive function decreased significantly with increasing CO2 levels., Conclusions: POC are widely used as plasticizers, flame retardants and floor sealing. This is the first report of a correlation between TCEP in indoor air samples and impairment of cognitive performance in school children. As a precautionary measure, it is recommended to prohibit the use of toxic chemicals and those suspected of a toxic potential in children's environments such as schools.

Background: Occupational mineral dust exposure is a well-known risk factor for numerous respiratory and systemic diseases. The aim of the present longitudinal study was to assess the influence of work-associated dust exposure on spirometric results. Furthermore, the impact of implementation of stricter limit values for occupational contact with quartz dust on lung function was evaluated., Methods: Anthropometric data (age, gender, BMI), smoking behavior, and lung function parameters (FVC, FEV1, MEF50) from 7,204 medical examinations of 3,229 female and male workers during the years 2002-2010 were examined following Austrian standards for occupational medicine and the guidelines of the European Respiratory Society. Analysis of data was performed using models of multiple linear regression., Results: Lung function decrease over time was associated with smoking habits and duration of occupational dust exposure. Specifically, occupational quartz exposure negatively influenced the annual lung function parameters (FVC, -6.68 ml; FEV1, -6.71 ml; and MEF50, -16.15 ml/s, all p < 0.001). Thus, an overadditive effect of smoking and work-related contact with quartz was found regarding decline in MEF50 (p < 0.05). Implementation of stricter occupational limit values for dust exposure resulted in a highly significant deceleration of the annual decrease in respiratory function (p = 0.001)., Conclusions: Individual smoking habits and occupational dust exposure had a negative impact on lung function. To reduce the risk of loss of respiratory capacity, smoking cessation is especially recommended to workers exposed to quartz dust. Moreover, stricter limit values could prevent chronic occupational damage to the respiratory system.

The dependency on carbon-based fossil energy and growing awareness of climate change issues has induced ambitious policy initiatives to promote renewable energy sources for indoor heating. Combustion of regionally available material such as wood is considered a carbon-neutral alternative for oil and gas, but unregulated revival of wood stoves may cause detrimental health effects. For the prognosis of the health impact of air pollution due to the use of wood stoves, Upper Austria served for a case study. On the basis of recent measurements of particulate matter <10 μm in aerodynamic diameter (PM10) and nitrous gases (NO(x)), we compared the air pollution attributable to present energy mix (termed scenario 1) with two alternatives: For scenario 2, we assumed replacement of light fuel oil by either fossil gas or biomass, and for scenario 3, replacement of light fuel oil by biomass only. Compared with the current exposure from scenario 1, the increased annual mean PM10 levels are estimated to lead to 101 (95% CI 56;146) and 174 (95% CI 92;257) additional deaths among 1.4 million inhabitants per year for scenarios 2 and 3, respectively. Without adequate strategies for reducing the emissions of domestic heating facilities, replacement of fossil energy sources could lead to an increased health risk.

Humans are exposed to a broad variety of man-made chemicals. Human biomonitoring (HBM) data reveal the individual body burden irrespective of sources and routes of uptake. A first population-based study was started in Austria in 2008 and was finished at the end of May 2011. This cross sectional study aims at documenting the extent, the distribution and the determinants of human exposure to industrial chemicals as well as proving the feasibility of a representative HBM study. Overall, 150 volunteers (50 families) were selected by stratified random sampling. Exposure to phthalates, trisphosphates, polybrominated diphenyl ethers (PBDE), bisphenol A (along with nonyl- and octyl phenol) and methyl mercury was assessed. Sixteen of 18 PBDE determined were detected above the limit of quantification (LOQ) in blood samples with #153 and #197 the most abundant species. Bisphenol A in urine was measured in a subsample of 25 with only 4 samples found above the LOQ. In 3 of 100 urine samples at least one of 8 trisphosphate compounds assessed was above the LOQ. These first analytical results of the human biomonitoring data show that the body burden of the Austrian population with respect to the assessed compounds is comparable to or even lower than in other European countries. Overall, the study revealed that in order to develop a feasible protocol for representative human biomonitoring studies procedures have to be optimized to allow for non-invasive sampling of body tissues in accordance with the main metabolic pathways. Procedures of participants' recruitment were, however, labor intensive and have to be improved., (Copyright © 2011 Elsevier GmbH. All rights reserved.)
