Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 56(1), P. 78 - 97

Published: Dec. 21, 2021

Persulfate-based nonradical oxidation processes (PS-NOPs) are appealing in wastewater purification due to their high efficiency and selectivity for removing trace organic contaminants complicated water matrices. In this review, we showcased the recent progresses of state-of-the-art strategies electron-transfer regimes PS-NOPs, including design metal metal-free heterogeneous catalysts, situ/operando characterization/analytical techniques, insights into origins mechanisms. a typical process (ETP), persulfate is activated by catalyst form surface complexes, which directly or indirectly interact with target pollutants finalize oxidation. We discussed different analytical techniques on fundamentals tactics accurate analysis ETP. Moreover, demonstrated challenges proposed future research ETP-based systems, such as computation-enabled molecular-level investigations, rational real-scenario applications environment. Overall, review dedicates sharpening understanding ETP PS-NOPs presenting promising remediation technology green chemistry.

Occurrence, toxicity and ecological risk of Bisphenol A analogues in aquatic environment – A review

Ecotoxicology and Environmental Safety, Journal Year: 2020, Volume and Issue: 208, P. 111481 - 111481

Published: Oct. 23, 2020

Bisphenol analogues (BPs) have been widely applied to industry as the substitutes for bisphenol A (BPA), which detected frequently in surface water, sediment, sewage and sludge. The presence of BPs natural environment could pose risks aquatic ecosystem human health. This study outlined occurrence, toxicity manifested their potential ecological risk throughout world. As BPA was losing its dominance, while were occupying a large part, especially S (BPS), F (BPF) AF (BPAF). In some heavily polluted areas, concentration reached µg/L environment, effluent plants higher than that water. content sludge sediment more aqueous phase. All other BPS P (BPP) had moderate toxicity. current data supports exposure may adverse effects on dysfunction endocrine system such thyroid hormone concentration, enzyme activity, even cell dysfunction, gene damage chromosomal abnormalities. According quotient (RQ), BPF shows highest China, Japan South Korea, followed by BPS. occurrence bisphenols neurotoxicity organisms merit further investigation.

Concentrations of bisphenol A and its alternatives in paired maternal–fetal urine, serum and amniotic fluid from an e-waste dismantling area in China

Environment International, Journal Year: 2020, Volume and Issue: 136, P. 105407 - 105407

Bisphenol A (BPA) and its alternatives are suspected endocrine disruptors. However, prenatal exposure transplacental transfer of bisphenols (BPs is still limited. Therefore, BPA six in maternal serum (MS), urine (MU), cord (CS), amniotic fluid (AF) samples collected from 106 maternal-fetal pairs an e-waste dismantling site Southern China were determined. AF (BPAF) bisphenol S (BPS) the dominant observed MS CS, geometric mean (GM) concentration BPAF (0.013 ng/mL MS, 0.097 CS) BPS (0.01 0.03 CS was lower than that (0.5 1.2 CS). The ratios concentrations between MU (MU:MS ratio) over three times higher those (AF:CS ratio), thereby suggesting low biotransformation/metabolism fetuses. placental rates BPs (i.e., CS:MS compound-specific (BPAF 3.26, 1.94, 1.11). Results suggest can pass through barrier. positively related to molecular weight or log Kow values. This finding indicates active transport responsible for BPs.

Oxidative Stress, Endocrine Disturbance, and Immune Interference in Humans Showed Relationships to Serum Bisphenol Concentrations in a Dense Industrial Area

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(3), P. 1953 - 1963

Published: Jan. 26, 2021

Bisphenol A (BPA) analogues, used in a range of products due to health concerns regarding BPA, have emerged as ubiquitous environmental contaminants worldwide. This study aims evaluate the levels nine bisphenols (BPs) and eight biomarkers (malondialdehyde, MDA; 8-hydroxy-2′-deoxyguanosine, 8-OHdG; estradiol, E2; follicle-stimulating hormone, FSH; luteinizing LH; complement compound 3, C3; immunoglobulin M, IgM c-reaction protein, CRP) human serum (n = 353) explore their potential relationships. The detection rates (DRs) BPs samples taken from people working dense industrial area Shenzhen (Guangdong Province, China) were over 72% except for bisphenol B (BPB) (DR 27.5%). mean concentrations P (BPP), BPB, F (BPF), FL (BPFL), 4,4′-dihydroxy-benzophenone (DHBP), AF (BPAF), 4,4′-thiodiphenol (TDP) S (BPS) 42.062, 2.083, 0.765, 0.578, 0.423, 0.402, 0.191, 0.120, 0.071 ng/mL, respectively. BPA BPFL significantly correlated with level oxidative stress indices MDA BPAF, DHBP strongly endocrine disturbance E2, FSH, BPF, DHBP, BPAF apparently related immune interference C3 IgM. also suggests multiple impacts (oxidative stress, disturbance, interference) mediated by vivo.

Meat and meat products are often consumed in our daily diet, providing essential nutrients. Contamination by chemical hazards, including bisphenol A (BPA) products, is a concern continuously monitored. BPA well-known for its endocrine-disrupting properties, which may cause potential toxicological effects on reproductive, nervous, immune systems. Dietary consumption the main route of exposure, major contributor. exposure from focus this review. This review found that has been widely detected canned non-canned products. assumed to be predominantly migration can coatings. Relatively low levels observed source contamination these yet definitively identified. recent European Food Safety Authority (EFSA) draft opinion proposed lower tolerable intake 4 μg kg body weight (bw)-1 day-1 0.04 ng day-1, therefore health risks need addressed. investigated at farm, industrial processes, retail levels. Data gaps literature also identified improve future food safety industry. Also, unified risk assessment strategy proposed.
