Time trends of perfluorinated compounds from the sediment core of Tokyo Bay, Japan (1950s-2004).
Perfluorinated compounds (PFCs) were detected in sediment core samples collected in Tokyo Bay to reveal their time trends. The core sample deposited during 1950s-2004 was divided into two- to three-year intervals and the concentrations of 24 types of PFCs were determined. Perfluorooctane sulfonate (PFOS) decreased gradually from the early 1990s and its precursor decreased rapidly in the late 19...
متن کاملMass Balance of Dioxins in Tokyo Bay and Kasumigaura Lake Basins in Japan
Introduction A number of severe soil and air pollution cases around municipal and industrial waste incinerators have recently been found in Japan. It is tme that the amount of waste incinerated in Japan is very high compared with other countries; however, it must be clarified whether the incinerators are the sole cause ofthe present dioxin pollution problem. In this study, the mass balance of d...
متن کاملHorizontal and vertical distribution of estrogenic activities in sediments and waters from Tokyo Bay, Japan.
Endocrine-disrupting chemicals with estrogenic activity (e.g., alkylphenols) have been detected in coastal Japan. We aimed to determine estrogenic activity in extracts of river water, seawater, sediments, and sediment cores from Tokyo Bay by in vitro gene expression assay. Fifty-one of 57 extracts had some estrogenic activity. E2 equivalents (ng E2 equivalents per gram dry weight or per liter a...
متن کاملSpatial distribution and partitioning of polychlorinated biphenyls in Tokyo Bay, Japan.
Spatial distributions and partitioning of polychlorinated biphenyls (PCBs) in Tokyo Bay, Japan, were evaluated by measuring the concentrations of all 209 PCB congeners in surface and bottom waters and bottom sediment at 10 locations. The dissolved + particulate summed congener concentrations (SigmaPCB [sum of the concentrations of all 209 PCB congeners]) in surface and bottom waters ranged from...
متن کاملEpizootiological study of hantavirus infection among Rattus norvegicus in Tokyo Bay area, Japan.
The prevalence of antibodies against hantavirus in 413 rats (Rattus norvegicus) captured in eight regions of the Tokyo Bay area from 1983 to 1992 were examined by the indirect fluorescent antibody test. Antibody-positive rats were found in Tokyo Port in 1983 (34.8%), 1984 (25.9%), 1985 (22.0%) and 1986 (15.6%), in Kasai Seaside Park in 1989 (3.2%) and 1990 (4.2%) and in Chiba Port in 1990 (6.7%...
