FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
11	Hazardous to the aquatic environment Long term (Chronic)	Not classified	- -	-	-	If chronic toxicity data are used, then it is classified as "Not classified" due to 21-day NOEC (reproduction) = 3.7 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1997); SIDS, 2004) although it is not rapidly degradable (a degradation rate by BOD: 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 2001; SIDS, 2004)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified as "Not classified" due to being not rapidly degradable (not readily degradable, a degradation rate by BOD: 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 2001; SIDS, 2004)), and 96-hour LC50 > 100 mg/L for fish (Oryzias latipes) (Results of Aquatic Toxicity Tests of Chemicals conducted by Environment Agency in Japan (Environment Agency, 1997)).
