Estimated Mass Balances of Perfluorinated Chemicals in Tokyo Bay

Introduction Perfluorinated chemicals (PFCs) have been used widely as surfactants, lubricants, paper and textile coatings, polishes, food packaging, and fire-retarding foams over the past fifty years. Some of these chemicals, such as perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), are persistent in the environment and have been found in wild animal samples around the wor...

A significant net sink for CO2 in Tokyo Bay

Most estuaries and inland waters are significant source for atmospheric CO2 because of input of terrestrial inorganic carbon and mineralization of terrestrially supplied organic carbon. In contrast to most coastal waters, some estuaries with small freshwater discharge are weak source or sometimes sink for CO2. Extensive surveys of pCO2 in Tokyo Bay showed that the overall bay acts as a strong n...

Comparative study of the aerobic, heterotrophic bacterial flora of Chesapeake Bay and Tokyo Bay.

A comparative study of the bacterial flora of the water of Chesapeake Bay and Tokyo Bay was undertaken to assess similarities and differences between the autochthonous flora of the two geographical sites and to test the hypothesis that, given similarities in environmental parameters, similar bacterial populations will be found, despite extreme geographic distance between locations. A total of 1...

Source Identification of Polychlorinated Biphenyls in Tokyo Bay Sediment

Introduction To employ improved countermeasures against PCB sources and to reduce the risk to aquatic biota, it is important to identify sources and migration pathways and ascertain their contribution to PCB pollution . Thus, a wider range of studies is required to identify potential PCB sources in the environment. The objective of this study is to identify PCB pollution sources affecting Tokyo...
