ENVIRONMENTAL HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
11	Hazardous to the aquatic environment Short term (Acute)	Category 2	- -	H401	P273 P501	It was classified in Category 2 from 96-hour EC50 = 6.2 mg/L for algae (Pseudokirchneriella subcapitata) (SIAP, Conclusions Agreed in CoCAM 4, 2013).	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
11	Hazardous to the aquatic environment Long term (Chronic)	Category 3	- -	H412	P273 P501	If chronic toxicity data are used, then it is classified in Category 3 due to rapid degradability (a degradation rate by BOD (NH3): 88% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1975)), and 50-day NOEC = 0.6 mg/L for fish (Oncorhynchus mykiss) (SIAP, Conclusions Agreed in CoCAM 4, 2013). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, there are data: 96-hour EC50 = 6.2 mg/L for algae (Pseudokirchneriella subcapitata) (SIAP, Conclusions Agreed in CoCAM 4, 2013). However, it is rapidly degradable (a degradation rate by BOD (NH3): 88% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1975)), and low bioaccumulation is estimated (log Kow = -0.38 (HSDB, 2013)). Therefore, it is classified as "Not classified." By drawing a comparison between the above results, it was classified in Category 3.

12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in the Annexes to the Montreal Protocol.	FY2013	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0))
