Fly ash is a serious
source of air pollution since it remains air borne for a long period of time
and causes health hazards. Besides being a health hazard, fly ash degrades the
environment. Earthworms are globally accepted as a model organism in
terrestrial ecotoxicology for assessment of environment pollution. This study
evaluated the effect of different concentrations of fly ash on biochemical
responses in the earthworm, Eisenia fetida. Earthworms were allowed to grow in
different proportion of fly ash (70-30%, 50-50% and 30-70%) for 1, 7 and 14 day.
The biochemical markers viz. catalase (CAT), superoxide dismutase (SOD),
glutathione peroxidase (GPx) and malondialdehyde (MDA) level were measured. The
activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and
malondialdehyde (MDA) were significantly increased. These results demonstrate
that fly ash has adverse biological effects on the indicator organism Eisenia
fetida. - See more at:
