Horizontal 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 کاملDistribution and Abundance of resting cysts of Alexandrium tamarense and/or A. catenella (Dinophyceae) in Tokyo Bay, Japan
Sediment samples collected at 33 stations in Tokyo Bay during the autumn of 1999 were examined to determine the distribution and abundance of resting cysts of Alexandrium tamarense and/or A. catenella. Extremely low concentrations of cysts were observed in Tokyo Bay compared with previously investigated sites in the Seto Inland Sea and Lake Hamana which have almost the same marine environmental...
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 کاملA study on the composition of size-fractionated suspended particulate matter in shallow coastal waters of Chabahar Bay
Abstract In the present study, sampling and analysis of size-fractionated suspended particulate matter (SPM) in coastal waters of Chabahar Bay have been done for the first time. Sampling has been conducted on December 25 of 2018 from 5 stations in different locations of the Bay in order to evaluate the effects of natural and human activities on SPM mass and composition. With an overall average...
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...
