Endocrine disruptors are widely present 1999.12.15

The Ministry of Construction summarized the results of the survey on endocrine disruptors, which were conducted in 1999 for the first-class river and major sewage facilities. In the water quality survey, five chemical substances such as nonylphenol and bisphenol A were confirmed at many points while low concentrations of hormones derived from human animals. Both the sediment survey and the sewer facility survey were detected at many points, and both tended to be similar to the 98 Year survey.
