Ecotoxicity: Fish: Fathead Minnow: LC50 = 1618 mg/L; 96 Hr.; UnspecifiedFish: Goldfish: LC50 = 5.75 mg/L; 48 Hr.; UnspecifiedWater flea EC50 = 1.4 mg/L; 48 Hr.; UnspecifiedAlgae: EC50 = 0.16 mg/L; 96 Hr.; UnspecifiedBacteria: Phytobacterium phosphoreum: EC50 = 37.5 mg/L; 30 Minutes; Microtox test No data available.
Environmental: Biodegradation in aquatic environments is not expected to be an important environmental fate process. A 0% theoretical oxygen demand was observed for 1,4-benzenediamine in a Warburg apparatus during a 5 day incubation period. A measured pKb value of 6.2 indicates that the protonated form of 1,4-benzenediamine will exist at environmentally significant pH and this may affect the environmental fate of this compound in aquatic environments.
Physical: Vapor-phase 1,4-benzenediamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be about 2 hours.
Other: Do not empty into drains.

Section 13 - Disposal Considerations

Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3. Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classification.
