ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - It was classified into Not classified from 96 hours LC50=164mg/L of the fish (Fathead minnows) (HSDB (2004)). In addition, methyl-1,3-phenylene diisocyanate (isomer mixture of this substance) was classified into Category 1.
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Since acute toxicity was classified into Not classified (acute toxicity is not reported within the aqueous solubility concentrations) and the bio-accumulation was low (log Kow=3.74 (PHYSPROP Database (2005))), it was classified into Not classified. In addition, the chronic toxicity of methyl-1,3-phenylene diisocyanate (isomer mixture of this substance) was classified into Category 1.
