Genotoxicity of wastewater samples from sewage and industrial effluent detected by the Allium root anaphase aberration and micronucleus assays.
The genotoxicity of wastewater samples from sewage, and industrial effluent from the Amritsar, India, area were investigated using the Allium micronucleus and anaphase aberration assays. Raw sewage samples and acetone extracts of the dehydrated sewage were use for treatment of the Allium roots. Industrial effluents were collected and stored in the form of sludge (semi-dried matter). The acetone extracts of the sludge samples were also used for treatment of the Allium roots. From the Allium root micronuclei tests on the sewage extracts, no significant increase in the number of micronuclei was found in comparison with negative controls. All the other extracts from industrial effluent showed positive responses both in the micronucleus and anaphase aberration assays.
