Association Between Prenatal Exposure to Per‐ and Poly‐Fluoroalkyl Substances From Electronic Waste Disassembly Areas and Steroid Hormones in Human Milk Samples

GeoHealth, Journal Year: 2024, Volume and Issue: 8(8)

Published: Aug. 1, 2024

Abstract Per‐ and poly‐fluoroalkyl substances (PFAS), which are long‐lasting environmental contaminants that released into the environment during e‐waste disassembly process, pose a threat to human health. Human milk is complex dynamic mixture of endogenous exogenous substances, including steroid hormones PFAS. Therefore, in this study, we aimed investigate association between PFAS from women living close an area. In 2021, collected samples 150 mothers within 4 weeks delivery analyzed them via liquid chromatography‐tandem mass spectrometry determine levels 21 perfluorinated compounds five (estrone, estriol, testosterone, progesterone, androstenedione [A‐dione]). We also performed multiple linear regression analysis clarify maternal exposure hormone concentrations. Our results indicated PFOA PFOS were positively associated with estrone ( β , 0.23; 95% CI, 0.08–0.39) A‐dione 0.186; 0.016–0.357) concentrations milk, respectively. Further, average estimated daily intake 36.5 ng/kg bw/day (range, 0.52–291.7 bw/day) 5.21 0.26–32.3 bw/day), Of concern, breastfeeding infants study area was higher than recommended threshold. These findings suggested prenatal process can influence milk. Increased efforts mitigate mother infant pollutants required.

Insights into PFAS contaminants before and after sewage discharges into a marine protected harbour

Per and polyfluoroalkyl substances (PFAS) their degradation products are a concern to human ecosystem health. Wastewater treatment plants not efficient at removing PFAS compounds thought be major source of these marine environments. The sewerage infrastructure in the UK, has over 20,000 combined stormwater overflows (CSOs). These CSOs relief values whereby untreated wastewater can discharge under permit from Environment Agency with exceptional rain/snowfall conditions. discharged 3.6 million monitored hours into English rivers coasts 2023. Concerns have been raised about proximity CSO discharges highly protected habitats. This study is first determine that concentrations elevated bay (Langstone Harbour, England) following recent sewage releases compared an extended period without discharge. Analysis was carried out suite 54 which only one (PFHpA) detectable above LOD prior but 8 afterwards. included banned PFOS (Linear Branched 8.6 ng/L ∓ 0.90) PFOA (2.9 0.29) were annual average EQS for inland 'other' surface waters.
