Pesticides, which are associated with endocrine dysfunction, immunological dysregulation, and cancer, widespread sources of drinking water contamination. The state Paraná has a population 11 million, is the second largest grain producer in Brazil leading consumer pesticides. In this study, we analyzed extent contamination from proven, probable, or potentially carcinogenic pesticides (alachlor, aldrin-dieldrin, atrazine, chlordane, DDT-DDD-DDE, diuron, glyphosate-AMPA, lindane-γ-HCH, mancozeb-ETU, molinate, trifluralin) 127 grain-producing municipalities Paraná. Extensive was found, including legacy such as aldrin-dieldrin (mean 0.047 ppb), DDT-DDD-DDE (mean: 0.07), chlordane 0.181), lindane-HCH 2.17). Most were significantly above maximum limits for each one currently allowed (67% alachlor, 9.44% 96.85% 100% 80.31% 91.33% 12.6% trifluralin). Ninety-seven percent presented sum all at levels (189.84 ppb) European Union preconized (<0.5 ppb). Using mean pesticide concentration (ppb), exposed municipality, benchmark cancer risk pesticides, estimated minimum number cases attributable to pesticide-contaminated during period (total 542 cases). More than 80% attributed mancozeb-ETU diuron. Glyphosate-AMPA diuron-attributable strongly correlated total same (R = 0.8117 0.8138, respectively) well breast 0.7695 0.7551, respectively). Water detected city 0.58 p < 0.0001). These findings reveal extensive suggest that may increase region.

France is the first pesticide-consuming country in Europe. Glyphosate most used pesticide worldwide and glyphosate detected general population of industrialized countries, with higher levels found farmers children. Little data was available concerning exposure France. Our objective to determine French search for an association seasons, biological features, lifestyle status, dietary habits, occupational exposure. This study includes 6848 participants recruited between 2018 2020. Associated include age, gender, location, employment information. quantified by a single laboratory first-void urine samples using ELISA. results support contamination population, quantifiable 99.8% mean 1.19 ng/ml + / - 0.84 after adjustment body mass index (BMI). We confirm men through food water intake, as lower are associated dominant organic intake filtered water. Higher confirmed working wine-growing environment. Thus, our present show glyphosate, further contribute description widespread countries.

Glyphosate infiltrates the brain and increases pro-inflammatory cytokine TNFα: implications for neurodegenerative disorders

Journal of Neuroinflammation, Год журнала: 2022, Номер 19(1)

Опубликована: Июль 28, 2022

Abstract Background Herbicides are environmental contaminants that have gained much attention due to the potential hazards they pose human health. Glyphosate, active ingredient in many commercial herbicides, is most heavily applied herbicide worldwide. The recent rise glyphosate application corn and soy crops correlates positively with increased death rates Alzheimer’s disease other neurodegenerative disorders. Glyphosate has been shown cross blood–brain barrier vitro models, but yet be verified vivo. Additionally, reports exposure increases pro-inflammatory cytokines blood plasma, particularly TNFα. Methods Here, we examined whether infiltrates brain elevates TNFα levels 4-month-old C57BL/6J mice. Mice received either 125, 250, or 500 mg/kg/day of glyphosate, a vehicle via oral gavage for 14 days. Urine, samples were collected on final day dosing analysis UPLC–MS ELISAs. Primary cortical neurons derived from amyloidogenic APP/PS1 pups evaluate changes Aβ 40-42 burden cytotoxicity. RNA sequencing was performed determine transcriptome. Results Our revealed infiltrated dose-dependent manner upregulated both plasma tissue post-exposure. Notably, measures correlated levels. primary soluble RNAseq over 200 differentially expressed genes cell-type-specific deconvolution showed enrichment key biological processes oligodendrocytes including myelination, axon ensheathment, glial cell development, oligodendrocyte development. Conclusions Collectively, these results show first time brain, expression Aβ, disrupts transcriptome manner, suggesting this may detrimental outcomes regarding health general population.

Prenatal perfluoroalkyl substances exposure and maternal sex steroid hormones across pregnancy

Poly- and perfluoroalkyl substances (PFAS) are ubiquitous persistent environmental contaminants that may act as endocrine disruptors in utero, but the specific pathways unknown. We examined associations between maternal serum PFAS sex steroid hormones at three time points during pregnancy. Pregnant women participating Understanding Pregnancy Signals Infant Development (UPSIDE) study contributed biospecimens, questionnaire, medical record data each trimester (n = 285). (including perfluorooctanoic acid (PFOA), perfluorooctanesulfonic (PFOS), perfluorohexane sulfonic (PFHxS), perfluorononanoic (PFNA) perfluorodecanoic (PFDA)) were analyzed second-trimester samples by high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS). Total testosterone [TT], free [fT], estrone [E1], estradiol [E2], estriol [E3]) measured LC-MS/MS from trimester. Linear mixed models with random intercepts used to examine log-transformed concentrations hormone levels, adjusting for covariates, stratifying fetal sex. Results presented mean percentage difference (Δ%) levels per ln-unit increase concentration. In adjusted models, PFHxS was associated higher TT (%Δ 20.0, 95%CI: 1.7, 41.6), particularly among carrying male fetuses 15.3, 1.2, 30.7); this association strengthened pregnancy progressed. PFNA 7.9, 3.4, 12.5) PFDA 7.2, 4.9, 9.7) fT, again observed only fetuses. of E2 E3 female 13.2, 0.5, 29.1; %Δ 17.9, 3.2, 34.8, respectively). No PFOS PFOA. PFHxS, PFNA, disrupt androgenic estrogenic a sex-dependent manner.

Glyphosate is the most widely applied herbicide in agriculture. Glufosinate a broad spectrum used to manage glyphosate-resistant weeds. Despite widespread use of these herbicides, biomonitoring data – which inform risk assessment and management are sparse. To identify determinants urinary concentrations herbicides their metabolites pregnancy. We measured glyphosate, glufosinate, primary aminomethylphosphonic acid (AMPA) 3-methylphosphinicopropionic (3-MPPA) single spot urine specimen collected during first trimester pregnancy from Maternal-Infant Research on Environmental Chemicals (MIREC) study. MIREC recruited about 2000 pregnant women 10 Canadian cities between 2008 2011. UItra-Performance Liquid Chromatography coupled tandem mass spectrometry (UPLC-MS/MS) with sensitive limits detection quantify analyte concentrations. examined according maternal sociodemographics, sample collection characteristics, reported pesticide use, consumption fruits, vegetables, legumes, grain products. ANOVA models specific gravity-standardized chemical as dependent variable determine associations determinants. Among biobanked samples (n = 1829–1854), 74% 72% had detectable glyphosate AMPA, respectively. In contrast, one six percent glufosinate 3-MPPA, The geometric mean (95% CI) AMPA were 0.112 (0.099–0.127) μg/L 0.159 (0.147–0.172) μg/L, observed dose-response relationship whole bread higher Season self-reported not associated increased any analyte. detected majority this predominantly urban cohort.
