Aniliini riskianalüüs (eng)

"limitedevidence of a carcinogenic effect". Animal studies have shown an increase in tumors of the spleen in rats exposed to aniline hydrochloride. EPA calculated an oral cancer slope factor of 5.7 x 10-3 (mg/kg/d) -1 and an oral unit risk estimate of 1.6 × 10- 7 (µg/L)-1. d) Genotoxicity and mutagenicity Aniline did not induce unscheduled DNA repair in primary human or rat hepatocytes. In mice, aniline induced micronuclei in several studies, but only at very high dose levels in the toxic range. Negative results have been found in the analysis of sperm head anomalies and equivocal results in the dominant lethal test. e) Other toxic effects, e.g. immunotoxicity and local toxicity - No information available. f) Ecotoxicity Toxic to aquatic organisms. Accumulates in their bodies. 6. Contact The primary method of obtaining aniline - restoration of nitrobenzene. Not found in nature.
