Summary information of human health hazard assessment of existing chemical substances (II)

Under the Chemical Substances Control Law in Japan, initial hazard information on existing chemical substances is collected by the Ministry of Health, Labour and Welfare, Japan to assess potential initial risks to human health. This hazard information includes acute toxicity, repeated-dose toxicity, genotoxicity, and/or reproductive/developmental toxicity. In an attempt to disseminate such information more widely, we have been reporting this information. In the present report, a summary of hazard information is presented for the following five existing chemical substances: 2,3,4,4′-tetrahydr oxybenzophenone (CAS: 31127-54-5); 1-propene, tetramer (CAS: 6842-15-5); 4-chlorobenzaldehyde (CAS: 104-88-1); diammonium hydrogen 2-hydroxypropane-1,2,3-tricarboxylate (CAS: 3012-65-5); and 2-nitrop- cresol (CAS: 119-33-5). Additionally, we created a dossier for the clarification and evaluation of each study in English using the International Uniform Chemical Information Database version 5.
