| Abstract: | A case study was carried out to determine the bio-degradability of α-HCH in waste dumps polluted with HCH-isomers. Polluted soil was homogenized through a 2 mm sieve. The degradation of α-HCH (5300 mg kg?1) occurred under anaerobic as well as under aerobic conditions; the concentration decreased in 20 weeks with 35% and 55% respectively. Addition of glucose, glutamic acid and peptone to the polluted soil hardly affected the degradation rate of α-HCH. |
