Environmental Impact 4-Aminoazobenzene may be released to the environment in wastewater during it's production and use as a dye and as a chemical intermediate. It should not bioconcentrate appreciably in aquatic organisms. However, because of the lack of experimental data, the fate of 4-aminoazobenzene in natural waters is unknown. In the atmosphere, 4-aminoazobenzene should exist primarily adsorbed to particulate matter and in aerosols and be subject to gravitational settling.
Human exposure is primarily in the workplace via dermal contact.
It may also biodegrade, with sufficient acclimation. No studies of degradation in soil samples were available. The fate of 4-aminoazobenzene in natural waters is unknown. Experimental data in environmental systems, however, are lacking. In the atmosphere, 4-aminoazobenzene would exist primarily adsorbed to particulate matter and in aerosols.
