- Abstract
Human biomonitoring of the exposure to pesticides is usually performed in biological matrices such as urine and plasma. However, the possibility of using less invasive matrices allows the screening of large number of subjects. The objective of this study was to evaluate the body burden of the exposure to the most widely used herbicide, Glyphosate (GLY), and its main metabolite, the aminomethylphosphonic acid (AMPA), in different populations from the province of Córdoba (Argentina), and to propose the saliva as a matrix for possible implementation in biomonitoring of the exposure to pesticides. Glyphosate and AMPA concentrations were evaluated in urine, plasma, and saliva of subjects occupationally and environmentally exposed to pesticides from one of the most important agricultural areas of Argentina. Gas chromatography coupled to tandem mass spectrometry (MS/MS) was used for the identification and quantification of the analytes. Both GLY and AMPA were quantified in all matrices with higher detection frequency (DF) in the occupationally exposed group than in non-occupationally exposed individuals. Among evaluated matrices, the highest DF and concentration levels of GLY were found in saliva. Moreover, the only statistical difference between groups of subjects were found for GLY and AMPA concentrations in saliva, indicating the possible use of this non-invasive human matrix to evaluate different levels and scenarios of exposure. No significant correlation was found between GLY and AMPA levels in saliva and the traditional matrices (urine and blood) used to measure exposure to pesticides. This is the first report of the presence and concentrations of GLY and AMPA in human saliva samples. Results of the present study are relevant for future biomonitoring of the exposure to GLY, but also to pesticides in general. Saliva deserved further investigation as an alternative, easy, and economical matrix involving less invasive methods for biomonitoring and screenings of large p

- Abstract
An analytical method for the simultaneous determination of glyphosate (GLY) and its main derivative, aminomethyl-phosphonic acid (AMPA), in human urine has been developed using gas chromatography coupled to tandem mass spectrometry (MS/MS) operated in multiple reaction monitoring mode (MRM). Sample preparation involved dilution of urine with water and derivatization with a mixture of trifluoroacetic acid anhydride and trifluoroethanol. Derivatization conditions such as reaction time and temperature, derivative stability, injection solvent, MS ionization mode and MS-MS transitions, among others, were studied to obtain the highest method sensitivity. The target compounds were initially quantified by the isotope dilution method using isotopically labelled analogs of GLY and AMPA as internal standards. However, due to spectral overlap between GLY and labelled GLY in the selected quantitative transition, a quantification method based on isotope pattern deconvolution (IPD) has been developed. The instrumental limits of detection were 0.05 ng mL−1 for both compounds, while the method detection limits were 0.39 and 0.25 ng mL−1, for AMPA and GLY, respectively. The mean recoveries from urine and water spiked at different concentrations were 77 and 69% for AMPA and 90 and 102% for GLY, respectively, with mean relative standard deviations of 8–10% (urine samples, n = 12) and 3.6–4% (water samples, n = 6). Once validated, the feasibility of the method was tested by determination of AMPA and GLY in human urine samples from people living close to agricultural areas. The developed method affords the determination of these compounds at trace concentrations in complex matrices such as urine, avoiding elaborate handling and cleanup steps. Isotope pattern deconvolution has proven to be a successful alternative to calibration curve for GLY overriding the method uncertainties associated to spectral overlapping.

- Abstract
Despite potential health implications, data on the presence of Glyphosate (GLY) and other non-GLY herbicides in human matrices remain scarce. This study aimed to develop a simple and cost-effective methodology for detecting and quantifying GLY, its primary biodegradation product; aminomethylphosphonic acid (AMPA); and glufosinate (GLU) in plasma and urine of environmentally and occupationally exposed populations from the province of Córdoba (Argentina). Different alternatives of pre-treatment, derivatization with FMOC-Cl, solid phase extraction, and final sample conditioning steps were evaluated to improve the quantification of the herbicides by a high-performance liquid chromatography system coupled to a triple-quadrupole mass spectrometer. Recoveries ranged from 39 to 84% in both matrices, while limits of quantification were 3, 1, and 0.3 ng/mL and 3.6, 5.1, and 0.3 ng/mL for AMPA, GLY, and GLU in plasma and urine, respectively. In plasma samples, GLY was the most frequently detected analyte (32%), followed by GLU (10%). In urine samples, GLU was the most frequently detected herbicide (13%), followed by GLY (6%). No differences between group or matrix correlations were found. This study is the first report of GLU in human biological matrices and should be used to establish baseline values for future surveillance systems.

Tesis - Doctorado en Ciencias de la Salud - Universidad nacional de Córdoba. Facultad de Ciencias Médicas. Secretaria de Graduados en Ciencias de la Salud, 2022 Antecedentes: el riesgo cardiometabólico implica una compleja desregulación de procesos inflamatorios y oxidativos con la modulación del sistema nervioso autonómico. La actividad física (AF) podría estar relacionada con un menor estatus inflamatorio y oxidativo mientras que el tiempo sedentario (SEDT) podría tener un efecto desfavorable, incrementando la inflamación, el estrés oxidativo y alterando la regulación autonómica aumentando el riesgo de enfermedad cardiometabólica. A la vez, potenciales factores, tal como la aptitud cardiorrespiratoria (CRF), la edad y la composición corporal podrían afectar la asociación entre AF, SEDT y los marcadores de inflamación y estrés oxidativo. Objetivos: el objetivo general del presente estudio fue analizar relaciones entre patrones de actividad física, el nivel de aptitud aeróbica y biomarcadores de estrés oxidativo e inflamación en individuos con riesgo de enfermedades crónicas no transmisibles. Como objetivos específicos se incluyeron: determinar las asociaciones entre AF, SEDT, CRF y los niveles de marcadores inflamatorios y de estrés oxidativo; analizar la asociación entre la AF, SEDT, CRF y los índices de control autonómico [variabilidad de la frecuencia cardíaca (VFC) y recuperación de la frecuencia cardíaca post ejercicio (RFC)]; establecer las asociaciones entre los índices de VFC y RFC y los marcadores de inflamación y estrés oxidativo; y establecer si existen diferencias en la asociación entre AF, SEDT y marcadores inflamatorios utilizando métodos de medición objetivos y subjetivos de AF y SEDT. Métodos: la muestra total constó de 111 voluntarios (70 mujeres y 41 hombres, edad = 52,8 8,2 años; IMC = 29,1 6,4 kg•m-2) de entre 39-70 años pertenecientes al Estudio sobre Estilos de Vida y Marcadores de Estrés Oxidativo en Individuos con Riesgo Cardiometabólico desarrollado en el Hospital Nacional de Clínicas. Una submuestra de 44 individuos (29 mujeres y 15 hombres, edad = 49,5 6,4 años; IMC = 28,1 6,2 kg•m-2) participaron del estudio sobre evaluación objetiva de la AF y su relación con marcadores de inflamación, estrés oxidativo y control autonómico. Los datos fueron recolectados entre las 7.00 y las 10.30 A.M. en ayunas y en el siguiente orden: frecuencia cardíaca de reposo para el análisis de la VFC; muestra de sangre para la medición de marcadores bioquímico-clínicos [glucosa, triglicéridos totales, colesterol total, HDL-C, LDL-C y hemoglobina glicosilada (HbA1C) y fibrinógeno], inflamatorios [proteína C reactiva (PCR) y citoquinas (IL-1β, INF-γ, TNF, MCP-1, IL-6, IL-8, IL-10, IL-18, IL-23)] y de estrés oxidativo [actividad de la catalasa (CAT) y de la glutatión peroxidasa (GPX)]. Medidas de la presión sanguínea [sistólica (PAS) y diastólica (PAD)], antropométricas [talla, masa corporal y circunferencia de la cintura (CC)]. Además, se realizó una prueba submáxima en cicloergómetro para estimar el consumo máximo de oxígeno (VO2max) como medida de la CRF y con recuperación activa para valorar la RFC absoluta (FC a los 30 s, 1 min, 2 min, 3 min, 4 min y 5 min post ejercicio) y la RFC relativa (Δ30, Δ1, Δ2, Δ3, Δ4, Δ5) así como la cinética de la RFC [constante temporal (τ) y amplitud (FCamp)]. Posteriormente, los participantes completaron un cuestionario sobre sus hábitos de AF [Cuestionario Internacional de AF (IPAQ), versión corta] y siete días de monitoreo objetivo de AF mediante acelerometría [tiempo sedentario (SEDT), tiempo de AF ligera (AFL), tiempo de AF moderada (AFM), tiempo de AF vigorosa (AFV) y la suma de AF moderada a vigorosa (AFMV)]. Los análisis de VFC, RFC, la prueba de ejercicio y el monitoreo objetivo de la AF solo fue realizado en una submuestra de 44 participantes. Para los análisis se establecieron conglomerados de edad (adultos jóvenes, adultos de mediana edad y adultos mayores), de CRF (baja, moderada y alta) y un conglomerado compuesto de riesgo cardiometabólico (bajo riesgo y alto riesgo). Resultados: en la muestra total los diferentes modelos univariados (ajustados por las covariables de confusión) mostraron que el SEDT no se asoció significativamente con ninguno de los marcadores inflamatorios y lo mismo ocurrió con la AFMV. Sin embargo, se observaron asociaciones significativas entre la AFL e IL-1β (B = -0,004; P = 0,021) y entre la AFV y TNF-α (B = -0,017; P = 0,017) e IL-6 (B = -0,018; P = 0,04). Asimismo, se halló un efecto de interacción entre la AF y el SEDT con diferentes covariables, particularmente el sexo, la edad y la CC. El análisis de la AF y SEDT mediante el IPAQ mostró diferencias significativas entre hombres y mujeres respecto de los minutos diarios de AFMV, AFV y AF total (P < 0,05). En contraposición, no hubo diferencias significativas respecto del SEDT entre ambos sexos. Cuando se compararon los niveles de AF por conglomerados de edad, se observó que los participantes pertenecientes al grupo de adultos jóvenes exhibieron mayores niveles de AFV en comparación con el grupo de adultos de mediana edad (P < 0,05), pero no con respecto al grupo de adultos mayores. En los conglomerados de riesgo cardiometabólico tanto la AFV como la AFMV exhibieron una asociación inversa con la PAS y PAD. Adicionalmente, se observó un efecto de interacción entre el SEDT y la edad sobre la concentración de HDL-C (B = -0,003; P = 0,016). El conglomerado con mayor riesgo cardiometabólico exhibió mayores niveles de PCR y Fibrinógeno (P < 0,01). Por otra parte, en la submuestra de 44 participantes se observó que, en comparación con los hombres, las mujeres exhibieron mayor SEDT (P = 0,035), con menores frecuencias en la interrupción del sedentarismo (P = 0,014) mientras que exhibieron mayores niveles de IL-6 (P = 0,02) y TNF-α (P = 0,01) con menores índices de VFC (P < 0,05). Se observaron asociaciones ajustadas significativas entre el SEDT y los niveles de CPR (B = 0,006; P = 0,001) y MCP-1 (B = 0,003; P = 0,038) y entre ciertos índices de la VFC y marcadores de inflamación/estrés oxidativo mientras que los índices de la RFC estuvieron inversamente asociados con Ln CAT [Δ3 (B = -54,7; P = 0,042), Δ4 (B = -54,1; P = 0,021] and Δ5 vs. Ln PCR [B = -19,8; P = 0,033]. El conglomerado de mayor CRF mostró menores valores de TNF-α (P = 0,02) e IL-10 (P = 0,003) y mejores índices de VFC (P < 0,05). El análisis de concordancia entre las medidas objetivas y subjetivas del SEDT resultó en un sesgo de 42 66 min con límites de acuerdo de -88 a 172 min en tanto que para las medidas de AF los resultados mostraron un sesgo de 2,2 148,0 min con límites de acuerdo de -288 a 293 min. Conclusiones: tomados conjuntamente, los resultados del presente estudio sugieren que prolongados tiempos de sedentarismo combinados con bajos niveles de AF de intensidad moderada a vigorosa pueden incrementar el ambiente inflamatorio y el estrés oxidativo. El aumento del estado proinflamatorio, a su vez, podría estar relacionado con una desmejora del control autonómico (i.e., equilibrio simpático-vagal) incrementando así el riesgo de enfermedad cardiovascular. Los resultados también muestran que la CRF es un potente modulador, no solo de la respuesta inflamatoria ante factores de riesgo cardiometabólicos sino también de la regulación autonómica de dicha respuesta. La baja concordancia observada entre las medidas de AF y SEDT obtenidas con el método subjetivo y el objetivo indican que las diferencias entre las asociaciones de la muestra completa y la submuestra se deban en parte al instrumento de evaluación utilizado. The increased use of pesticides has augmented the chances of contact between populations and these compounds, increasing consequently accident chances and expositions held over time. The aims of the present thesis were: a- To evaluate the exposure to pesticides in occupationally exposed subjects (OE; terrestrial applicators of pesticides) of the province of Córdoba, using two indexes of pesticide exposure, one indicative of the intensity level of the exposure (IIE) and another of the cumulative exposure level (IEA) and its scales, and validate their usefulness using health conditions, as well as effect and exposure biomarkers; and b- To estimate the exposure to pesticides through a dietary risk analysis in OE subjects and their controls (subjects not occupationally exposed to pesticides; NOE). Cross-sectional studies were designed to evaluate the exposure to pesticides and the health conditions of the participants, with the due approval of the Ethics Committee for Health Research. Enrolled subjects provided information on perceived symptomatology and biological samples for the determination of effect biomarkers (cholinesterase activity in plasma and erythrocytes, and markers of genotoxic damage (micronuclei (MN), sister chromatid exchange (ICH), chromosomal aberrations (AC) and comet assay (EC)), and exposure biomarkers (concentration of pesticides in plasma and urine). The perceived symptomatology and all the genotoxic damage biomarkers evaluated were significantly higher in the OE group. These resutls show that the occupational exposure to pesticides would negatively affect the health of workers. Cholinesterase activity was within the reference range for both groups of subjects, but with higher levels of activity within the OE group. In plasma, organochlorine pesticide residues of hexachlorobenzene (HCB), β- hexachlorohexane (β-HCH), α-endosulfan, dichlorodiphenyl dichloroethylene (pp ́DDE), endrin, β-endosulfan, dichloro diphenyl trichloroethane (pp ́DDT) endosulfan sulfate and mirex were found, without significant differences between groups, but with higher detection frequencies (FD) in the OE group. Within the OE group, the associations found between the IEA with neurological symptomatology and the IIE with the activity of plasmatic cholinesterases show the usefulness of the questionnaires used, to be propose as surveillance tools, and of the cholinesterase biomarkers to differentiate levels of exposure and to identify vulnerable groups. In urine, specific metabolites of the organophosphate (OP) pesticides pirimiphos, parathion and chlorpyrifos (2-diethylamino-6-methyl-4-pyrimidinol (DEAMPY), p- nitrophenol (PNP) and 3,5,6-trichloropyridinol (TCPY), respectively) were found, with a FD> 85%. With lower FD, malathion and diazinon metabolites (malathion dicarboxylic acid (MDA) and 2-isopropyl-4-methyl-6-hydroxypyrimidine (IMPY)) were found. Concentration levels of DEAMPY found in this population were at least two times higher than those reported in other countries. The PNP FD (100%) suggests that the population was recently exposed to the banned pesticide. Regarding pyrethroid metabolites (PYR), the common degradation metabolite of cypermethrin, deltamethrin and permethrin, 3-phenoxybenzoic acid (3-PBA) was found in 100% of the population. With a lower FD, the specific cyfluthrin metabolite, 4-fluoro-3-phenoxybenzoic acid (4-F-3-PBA) was found, with statistical higher concentration in the OE group. The dietary risk analysis showed that the daily intakes of OP and PYR pesticides are within food safe values. However, the negative correlations found between cholinesterase activity, and the metabolites DEAMPY, IMPY and PNP, indicate a possible risk to human health, even at environmental levels of exposure. This thesis is the first biomonitoring integrating the study of health conditions, levels of pesticides in biological matrices and levels of exposure in terrestrial pesticide applicators in the country. It is also the first report of concentrations of OC, OP and PYR pesticides and/or their metabolites in biological matrices of an occupationally exposed population in the country and of the control population in the study areas. On the other hand, and from the health point of view, the knowledge of the health effects, in relation to the magnitude of the use of these compounds and the regular practices in the territory, provides essential elements to improve the knowledge of the conditions of occupational and environmental exposure to pesticides, identify shortcomings that allow reinforcing good agricultural practices and generate preventive proposals. These elements become of political relevance for decision-making in health and effective and timely health intervention, for the care of vulnerable groups and the protection of the entire population. 2024-03-16 Fil: Filippi, Iohanna.

GLYPHOSATE -- Environmental aspects ,PHOSPHONIC acids ,PARTICULATE matter ,FRESHWATER ecology ,ENVIRONMENTAL toxicology ,ENVIRONMENTAL risk assessment - Abstract
Glyphosate is themostwidely used herbicideworldwide. However, there are some uncertain aspects with respect to its environmental fate. To evaluate the existence and distribution of this pesticide and its metabolite, aminomethylphosphonic acid (AMPA), their presence in fresh water, sediment, and suspended particulate matter (SPM) was measured in samples collected in a river running across a large city and through areas with intensive and extensive agriculture. The aquatic risk associated to the occurrence of these compounds was estimated using the hazard quotient (HQ) calculation for water and sediment. From the analyzed samples, overall 35% contained glyphosate, AMPA, or both compounds. Concentrations of the analytes were spread in different percentages depending on the environmentalmatrices considered, with levels ranging from12 to 20 times higher for glyphosate and AMPA in sediment and SPM, as compared with the levels found in water. The most polluted area was situated within a green belt zone of the city; while in second place were sites located in areas of extensive agriculture. Aquatic organisms inhabiting areas both inside and outside agricultural areas are threatened by water glyphosate concentrations. Benthic organisms inside the greenbelt zone and inside the lower basin are threatened by the concentrations of glyphosate in sediment. Even when the concentrations measured in water were below the levels of concern for wildlife, results showed the risk of agricultural practices to aquatic biota. An update of the limits established for freshwater biota protection is needed. [ABSTRACT FROM AUTHOR]
