Voice to request the execution of an immediate environmental investigation begins to appear also in Japan in relation to DuPont, a chemical major manufacturer in the United States, having agreed to settle a class-action lawsuit in which residents claimed the compensation for water pollution and the health damage with chemical "PFOA" used when fluoroplastics product "Teflon" is manufactured.
A researcher who had attended the 7th Japan Society on Water Environment's symposium described on September 13, "It is necessary to clarify the pollutant pathway of the chemical with a high remaining beforehand like the Perfluorooctanoic acid, or PFOA. It is because it was not possible to move at once when restricting it by the law of the future if the pollutant pathway was not understood. It is too late when launching an inquiry after toxicity was clarified".
Also in Japan, the researchers have detected a high density Perfluorooctanoic acid, or PFOA in the Kinki region such as Osaka Prefecture.
