Maternal and prenatal exposure to organochlorine pesticides (OCP), arsenic (As), and fluoride (F−) is a critical public health concern. The present study assessed serum OCP residues and urinary As and F− levels in mother and newborn pairs who are residents of rural areas of Durango State, Mexico, from August 2018 to February 2019. Levels of OCP, As, and F− were measured in serum and urine samples by Gas chromatography – Tandem mass spectrometry (GC – MS/MS), Hydride generation – Atomic fluorescent spectrometry (HG-AFS, and ion-selective electron analysis (ISE), respectively, in 60 binomial mothers – newborns. Dieldrin, endrin aldehyde, and endosulfan-II were significantly higher in newborns than in mothers (
p ˂0.05). Meanwhile, no significant differences were observed for As and F− concentrations between mother – newborn pairs. Differences were observed in ∑Dienes and ∑DDTs comparing newborns with normal and low birth weights and a positive relationship in ƩDienes, ƩChlordanes, and ƩDDTs between mother and newborn pairs (p ˂ 0.05). These findings highlight the importance of extensive research regarding the influence of pollution. [ABSTRACT FROM AUTHOR]- Published
