Triclosan (TCS) and triclocarbon (TCC) are bactericides used in various consumer and personal-care products. Recent studies have revealed considerable levels of these bactericides in wastewater, aquatic wildlife, and human samples. Consequently, in this study we measured TCS and TCC in influent and effluent, sludge, and pond water/sediment samples from four(More)
Perfluorinated organic compounds (PFCs) such as PFOS, PFOA, PFBS, PFHxS, PFOSA and PFDoA were determined in river water, river sediment, liver of market fish and liver of wildlife samples from Japan. Concentrations of PFOA and PFOS in water samples were 7.9-110 and <5.2-10 ng/L. Only PFOA were detected in sediment from Kyoto river at 1.3-3.9 ng/g dry wt.(More)
Wastewater treatment plants (WWTPs) are a potential of source of polycyclic musks in the aquatic environment. In this study, contamination profiles and mass flow of polycyclic musks, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[gamma]-2-benzopyran (HHCB), 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN), and HHCB-lactone(More)
The purpose of this study was to examine the contamination and bioconcentration potential of mercury (Hg) in Yellow-ocher Brittle Gills known also as Yellow-ocher Brittle Gill or Common Russula (Russula ochroleuca) mushroom. Matured fruiting bodies of this fungus and soil samples were collected at ten spatially distant unpolluted sites in the northern part(More)
Environmental exposure to lead (Pb) is known to affect the developing nervous system causing cognitive deficits in children. The diffusible nitric oxide (NO) is a biological messenger known to be involved in brain development. We examined the developmental changes of neuronal nitric oxide synthase (nNOS) in cerebellum and hippocampus of developing rat brain(More)
Residues of organic contaminants--including toxaphene, DDT, trifluralin, hexachlorocyclohexanes, polychlorinated biphenyls, polycyclic aromatic hydrocarbons (PAHs) and nonylphenol--were measured in 32 cotton field soils collected from South Carolina and Georgia in 1999. Toxaphene, trifluralin, DDT and PAHs were the major contaminants found in these soils.(More)
Effects of lead (Pb) and chelators, such as EDTA, HEDTA, DTPA, NTA and citric acid, were studied to evaluate the growth potential of Sesbania drummondii in soils contaminated with high concentrations of Pb. S. drummondii seedlings were grown in soil containing 7.5 g Pb(NO(3))(2) and 0-10 mmol chelators/kg soil for a period of 2 and 4 weeks and assessed for(More)
Discharge of effluents from municipal wastewater treatment plants (WWTPs) is a route for the introduction of certain organic contaminants into aquatic environments. Earlier studies have reported the occurrence of perfluorochemicals in effluents from WWTPs. In this study, contamination profiles of perfluorinated compounds (PFCs), including perfluoroalkyl(More)
