Polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) were determined in muscle, liver and eggs of freshwater fishes from the lower reach of the Yangtze River, China. The present study is the first to report HBCD concentrations in the environment of China. The concentrations of PBDEs and HBCDs in muscle of freshwater fishes from the(More)
In the present study, the bioaccumulation and reactive oxygen species (ROS) generation were studied after fish (Carassius auratus) were exposed to different concentrations (0.01, 0.02, 0.05, 0.07 and 0.1 mg/L) of phenanthrene for 4 days. The accumulation of phenanthrene in liver increased with the exposure concentration (R(2)=0.88). A secondary spin(More)
Tris(1,3-dichloro-2-propyl) phosphate (TDCPP) and triphenyl phosphate (TPP) are frequently detected in biota, including fish. However, knowledge of the toxicological and molecular effects of these currently used flame retardants is limited. In the present study, an in vivo screening approach was developed to evaluate effects of TDCPP and TPP on(More)
Several organophosphate flame retardants (OPFRs) have been identified as known or suspected carcinogens or neurotoxic substances. Given the potential health risks of these compounds, we conducted a comprehensive survey of nine OPFRs in drinking water in China. We found total concentrations of OPFRs in tap water ranging from 85.1 ng/L to 325 ng/L, and(More)
Seeds of Vicia faba. L were grown in increasing concentrations of lead (Pb)-added soils (0-2,000 mg/kg). After germination of 25 days, roots were harvested to investigate oxidative stress, defense response and indicative biomarkers based upon chemical analyses and biological measurements. The results showed that higher concentrations of Pb-polluted soils(More)
Fourteen PBDE congeners from mono- to deca-BDE were determined in breast milk of primiparous mothers from two locations in East China, i.e. Nanjing (n=9), an urban area, and Zhoushan (n=10), a semi rural coastal area. PBDEs were detected in all the human breast milk samples of the present study, indicating that general population in these two locations are(More)
Heavy metal pollution is one of the most serous environmental issues globally. To evaluate the metal pollution in Jiangsu Province of China, the total concentrations of heavy metals in sediments and fishes from the Yangtze River and Taihu Lake were analyzed. Ecological risk of sediments and human health risk of fish consumption were assessed respectively.(More)
Sorption of tetrabromobisphenol A (TBBPA) in soil influences its fate and transport in the environment. The sorption behaviors of TBBPA in two soils with different characteristics were investigated using batch equilibration experiments in the study, and the impacts of ionic strength and pH on the sorption were also evaluated. The results showed that the(More)
OBJECTIVE We explored the effects of fructo-oligosaccharides (FOS) and phytic acid (PA) on the absorption of minerals and their interaction. METHODS A 3 x 2 factorial experiment was designed to evaluate the effects of FOS (in the presence or absence of PA) on the apparent absorption rate of minerals and the mineral status (plasma, hepatic, and bone) in(More)
