Human exposure to mercury due to goldmining in the Tapajos River basin, Amazon, Brazil: Speciation of mercury in human hair, blood and urine
To obtain the basic information on human exposure to mercury (Hg) due to gold mining activities in Amazon, total mercury (T-Hg) and methylmercury (MeI Ig) were determined for human hair, blood and/or
Polychlorinated biphenyls (PCBs) exert thyroid hormone-like effects in the fetal rat brain but do not bind to thyroid hormone receptors.
It is indicated that PCBs can interfere with TH signaling in the fetal brain by direct actions on the fetus rather than by producing maternal hypothyroidism.
Identification, quantification, and synthesis of a novel dimethoxylated polybrominated biphenyl in marine mammals caught off the coast of Japan.
This novel compound is consistently one of the most abundant compounds among those analyzed, including polybrominated diphenyl ethers (PBDEs), hexabromocyclodododecane (HBCDD), and methoxylated PBDEs.
Distribution of methyl sulfone metabolites of polychlorinated biphenyls and p,p'-DDE in human tissues.
It is suggested that the distribution patterns of MeSO2-CBs and MeSO1-DDE in humans differ between liver and other tissues, and these profiles differ from those found in other mammals, such as polar bears, porpoises, and otters.
PCB and PCB methyl sulfones in mink treated with PCB and various PCB fractions
Polychlorinated biphenyls with 5 or more chlorine atoms, and lacking vicinal hydrogens in 3,4-positions, were most efficiently retained in the mink, while CBs with chlorine atoms in 2,5-position and unsubstituted 3, 4- Positions were most readily metabolized.
Simultaneous determination by APCI-LC/MS/MS of hydroxylated and methoxylated polybrominated diphenyl ethers found in marine biota.
The APCI-LC/MS/MS method provides the different LOQ ranges between hydroxylated and neutral brominated analogs, and future work could apply the method to the full range of PBDE-like contaminants present in the environment and in biota tissues.
