Limited information exists on exposure to bisphenol A (BPA) by children, adults, and pregnant women in China. In the present study, we determined BPA concentrations whole blood collected from 10 children (1–5 years), 40 (30 nonpregnant), 30 fetuses (i.e., cord blood). Further, evaluate relationship between urinary concentrations, paired specimens of urine (n = 50 pairs) were an adult population. was found 46% all samples analyzed, with a geometric mean (GM) concentration 0.19 ng/mL. 84% GM...
Organophosphate esters (OPEs) are widely used as flame retardants and plasticizers in consumer industrial products. Human exposure to OPEs raises concerns due their endocrine disruptive potentials. Till now, the effects of on thyroid hormones (THs) mediating role oxidative stress pregnant women have not been studied. In this study, prenatal urinary concentrations OPE metabolites (mOPEs), levels free triiodothyronine (FT3), thyroxine (FT4), thyroid-stimulating hormone (TSH), 8-hydroxy-2-deoxy...
For the first time, we confirmed that PS nanoplastics can enter plant root cells through endocytosis, which will provide important new insights into microplastic-induced phytotoxicity.
Liquid crystal monomers (LCMs) are a class of emerging, persistent, bioaccumulative, and toxic organic pollutants. They detected in various environmental matrixes that associated with electronic waste (e-waste) dismantling. However, their occurrence distribution indoor outdoor dust on national scale remain unknown. In this study, dedicated target analysis quantified broad range 60 LCMs samples collected across China. The were frequently (n = 48) 97; 37 sampled concomitantly indoors dust)...
Recently, evidence of aromatic amine antioxidants (AAs) existence in the dust electronic waste (e-waste) dismantling area has been exposed. However, there is limited studies investigating occupational exposure and toxicity associated with AAs their transformation products (p-phenylenediamines-quinones, i.e., PPD-Qs). In this study, 115 42 hand wipe samples collected from an e-waste recycling industrial park central China were analyzed for 19 6 PPD-Qs. Notably, median concentration ∑6PPD-Qs...
Batch experiments investigated the effects of time, temperature, and initial concentration metal ions on heavy removal by tourmaline under acidic conditions to evaluate kinetics, thermodynamics, mechanisms. The results indicated that adsorption Cd(II), Zn(II), Ni(II) depended significantly all above-mentioned parameters. kinetics closely followed pseudo-second-order model. Langmuir, Freundlich, Temkin, Dubinin–Radushkevich models well described equilibrium isotherm at conditions. maximum...
To study the uptake pathways of 3 main hexabromocyclododecane diastereoisomers (α-, β-, and γ-HBCDs) in wheat, four closed chambers were designed to expose wheat HBCDs via air and/or soil for 4 weeks. The results showed that could be absorbed by both root from leaf air. Rt values (ratio root-to-leaf translocation total accumulation leaves) ranging 14.4 29.8% suggested acropetal within was limited. A negative linear relationship found between log Kow HBCD (p < 0.05). bioconcentration factors...
Electronic waste (e-waste) is a well-known source of plastic additives in the environment. However, e-waste-related occupational exposure to organophosphite antioxidants (OPAs) and relevant oxidation products—novel organophosphate esters (NOPEs)—via different pathways still unknown. In this study, six OPAs three NOPEs were measured 116 dust 43 hand-wipe samples from an e-waste dismantling area Central China. The median concentrations ΣOPAs ΣNOPEs 188 13,900 ng·g−1 workshop 5,250 ng·m−2...
Microplastics (MPs) are emerging contaminants in agricultural soil, whereas their effects on the rhizosphere microbial ecosystems and biogeochemical nitrogen cycles during plant growth remain unknown. Here, a 70-day greenhouse experiment was carried out with black fluvo-aquic soil to evaluate influence of polyamide (PA), polyethylene (PE), polyester (PES), polyvinyl chloride (PVC) MPs bacterial communities functions soybean rhizosphere. The PA treatment consistently affected rhizobacterial...
