Exposure of pregnant women to neonicotinoids in Wenzhou City, East China: A biomonitoring study

Environment International, Год журнала: 2024, Номер 189, С. 108811 - 108811

China produces and consumes a large amount of neonicotinoids. A non-negligible exposure to neonicotinoids might occur for Chinese pregnant women, but relevant data remain limited. To investigate the by urinary biomonitoring in women from Wenzhou City, East China. We selected 432 City 2022. total eight parent four metabolites were determined single spot urine liquid chromatography coupled mass spectrometry. Basic characteristics, physical activity, pre-pregnant body index, intake drinking water food investigated questionnaire. Health risk was assessed hazard quotient (HQ) index (HI) based on human safety thresholds derived different health endpoints. Neonicotinoids their had detection frequency between 0 % 80.1 %. At least one neonicotinoid or metabolite detected 93.5 samples. Except clothianidin (51.2 %) N-desmethyl-acetamiprid (80.1 %), frequencies other ranged 43.8 The summed concentrations all < LOD 222.83 μg/g creatinine with median concentration 2.58 creatinine. Maternal age, educational level, occupation, household income, screen time, associated metabolites. Pregnant higher consumption wheat, fresh vegetable, shellfish, milk, powdered milk Both HQ HI less than one. Overall, showed notable at neonicotinoid, although each specific generally low. Several items plants animals potential sources. low found current thresholds.

Characteristics of Neonicotinoids in Colostrum from Shanghai, China (2007–2019): Concentration Levels, Temporal Trends, and Potential Health Risk

Toxics, Год журнала: 2025, Номер 13(5), С. 366 - 366

Опубликована: Май 1, 2025

Neonicotinoids (NEOs) are widely used neuroactive insecticides with several adverse effects on human health. This study examined 186 colostrum samples collected at three time points between 2007 and 2019 from Shanghai, China to investigate the distribution temporal variations of NEOs. The median total concentration (ΣNEOs) was 136 ng/L, imidacloprid equivalent (IMIeq) 249 ng/L. N-desmethyl-acetamiprid (DM-ACE) had highest level 49.6 accounting for 43.9% ΣNEOs, followed by (IMI) (20.1 ng/L 22.1%). Thiamethoxam (THM), clothianidin, acetamiprid were also identified as important parent compounds (p-NEOs). Temporal suggested a decrease in IMIeq, DM-ACE concentrations 2013 2019; however, p-NEOs remained comparable. Distinct trends observed dinotefuran IMI. Maternal body mass index weight changes, which reflect dietary habits mothers, appeared influence IMI THM levels. No statistically significant relationships found birth parameters using full-term data 2019. estimated hazard quotients (≤0.003), far below risk threshold 1, generally indicated negligible health risks breastfeeding neonates. Nevertheless, substantial contribution warrants further investigation.
