Mutagenicity: No evidence found in public literature
Other Effects: Allergic reactions for sensitive individuals
Ecotoxicity: Harmful to fish and other aquatic life, disrupts aquatic food chain
Mobility: Reacts with moisture, binds to soil
Persistence: Hydrolyzes in moist environments to form phthalic acid derivatives
Bioaccumulation: Unlikely to bioaccumulate, converts rapidly to acids in water
Degradability: Decomposes in presence of moisture, but resulting acid may persist
Other Effects: Release to waterways may cause local ecosystem damage
Waste Treatment Methods: Collect solid waste in labeled, sealed containers
