It is the first time such chemicals were found in salmon in Japan, said the Ocean Research Institute's International Coastal Research Center that studied about 30 salmon in the Pacific coastal town of Otsuchi in Iwate Prefecture. Given that DDT has not been used in Japan following an international ban on its production and use, it is believed the chemicals are coming by air from Southeast Asia, where they are still used in some areas, the researchers said.

JAPAN - Residues of DDT and other highly toxic organic chlorine agrochemicals, which have been banned in Japan since the 1970s, were found in salmon returning to a Japanese river to spawn, researchers at a University of Tokyo institute said Thursday.
