title: Revision and establishment of Japanese drinking water quality guidelines for di(2-ethylhexyl) phthalate, toluene and vinyl chloride -- differences from the latest WHO guideline drafts.
abstract: The revision of the Japanese drinking water quality guidelines was established in May 2003. The WHO drinking water quality guidelines for the 3(rd) edition were also revised and the draft has been open to the public since last year. Most guideline values of each chemical in both Japan and WHO were quite similar; however, there are different overt values for three chemicals. In this short communication, we describe them and discuss the reason for taking the different toxicity endpoints and derivation method for these three chemicals, di(2-ethylhexyl) phthalate, toluene and vinyl chloride.
