Degradation of aniline, 4‐chloroaniline and 3,4‐dichloroaniline in various soilsThe degradation of aniline, 4‐chloroaniline and 3,4‐dichloroaniline was investigated in laboratory experiments with 4 different soil types and a concentration of 1ppm. The experiment time was 10‐16 weeks. Aniline was mineralized during 10 weeks from 16,2 to 26,3%, while the degradation rate was 12,3 to 17,2% with 4‐chloroaniline. With 3,4‐dichloroaniline degradation was reduced to 3,9 to 11,9%.At the end of the experiment 60% and more of the14C‐activity was bound to the soil complex and could not be extracted by different solvents. Because of the low degradation of chloroanilines and the strong sorption there should be an accumulation in the soil. Anilines are metabolites of different chemicals used in p
