Urinary Level of Dimethoate, Bisphenol a and Benzo[a]pyrene in the First-year Students of Hohai University From Different Geographical Regions
AI summary Read the abstract
Researchers measured urinary levels of three environmental chemicals—a pesticide (dimethoate), benzo[a]pyrene (a carcinogen), and bisphenol A (BPA, a plastic additive)—in university students from different regions of China. BPA was detected in the majority of students, confirming widespread human exposure to this plastic-derived endocrine disruptor.
Abstract Background : The objective of this study was to detect the urinary level of dimethoate, benzo(a)pyrene (BaP), and bisphenol A (BPA) in the first-year Hohai University students of different geographic origins. Methods : First-morning urine samples were collected from 540 healthy freshmen aged 17 to 19. Toxin levels were measured using β-glucuronidase hydrolysis followed by a high-performance liquid chromatography-tandem mass spectrometry-based method. Geometric means (GM) are presented by BMI (Body Mass Index) and different locations for these three toxins in a volume-based and creatinine-standardized way. Results : GM concentration of dimethoate, BPA and BaP were 9.47 µg/L (10.80 µg/g creatinine), 3.54 µg/L (4.04 µg/g creatinine) and 0.34 ng/L (0.39 ng/g creatinine), respectively. The GM concentration of dimethoate in males was significantly higher than that in females. The BMI higher than 23.9 had a higher GM concentration of dimethoate, BPA, and BaP. The inhabitant in the Southwest of China had a significantly lower GM concentration of dimethoate, BPA, and BaP than those who live in other locations of China. Conclusion: The average level of environmental toxins accumulation in freshmen is relatively high and differs in the youth who live in different regions. Besides, obesity is correlated to higher toxins levels in youth.

Urinary levels of dimethoate, bisphenol A and benzo[a]pyrene in first-year students of Hohai University from different geographical regions
AI summary Read the abstract
This study measured levels of dimethoate (a pesticide), bisphenol A (a plasticizer), and benzo[a]pyrene (a combustion byproduct) in the urine of first-year university students in Southwest China. Students from different regions showed different chemical exposure levels, and obesity was linked to higher concentrations of some toxicants.
Bisphenol A and its analogues in outdoor and indoor air: Properties, sources and global levels
AI summary Read the abstract
This review covers the presence of bisphenol A (BPA), a hormone-disrupting chemical used in plastic manufacturing, in indoor and outdoor air worldwide. BPA exposure through air and dust is a concern because it can interfere with hormones even at low levels, potentially affecting fertility, development, and metabolism. The review is relevant to microplastics because BPA is a common plastic additive that can leach from microplastic particles, adding to human exposure through multiple routes.
