11 Hazardous to the aquatic environment Short term (Acute) Category 3
-
-
H402 P273
P501 		As for this substance, it was decided that the classification was conducted as total ammonia based on expert judgment. It was classified in Category 3 from 96-hour LC50 = 13.0 mg/L for fish (Oncorhynchus mykiss) (a converted value equivalent to total ammonia. test substance: NH4Cl, pH: 8.29) (Thurston et al., 1981). The classification result was changed from the previous classification by changing the view on which substance was targeted.
11 Hazardous to the aquatic environment Long term (Chronic) Not classified
-
-
- - As for this substance, it was decided that the classification was conducted as total ammonia based on expert judgment. If chronic toxicity data are used, then it is classified as "Not classified" due to being rapidly degradable (rapidly nitrified in aquatic environment (SIDS, 2007)), and 32-day NOEC =3.47 mg/L for crustacea (Mysidopsis bahia) (a converted value equivalent to total ammonia. test substance: NH4Cl, pH: 7.92-8.01) (SIDS, 2007).
If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained (algae, fish), then it is classified as "Not classified" due to being rapidly degradable and a low bioaccumulation estimate (log Kow = -1.14 (SIDS, 2007)), despite 96-hour LC50 = 13.0 mg/L for fish (Oncorhynchus mykiss) (a converted value equivalent to total ammonia. test substance: NH4Cl, pH: 8.29) (Thurston et al., 1981).
From the above results, it was classified as "Not classified." The classification result was changed from the previous classification by changing the view on which substance was targeted and changing how to classify it in chronic toxicity.
12 Hazardous to the ozone layer Classification not possible
-
-
- - This substance is not listed in the Annexes to the Montreal Protocol.


NOTE:
  • GHS Classification Result by the Japanese Government is intended to provide a reference for preparing a GHS label or SDS for users. To include the same classification result in a label or SDS for Japan is NOT mandatory.
  • Users can cite or copy this classification result when preparing a GHS label or SDS. Please be aware, however, that the responsibility for a label or SDS prepared by citing or copying this classification result lies with users.
  • This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
  • Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
  • A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
  • An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
