Abstract
Soil samples are of significant environmental concern because they may act as sinks for different contaminants and can be accumulated by organisms at different trophic levels. In the present study soil extracts from Kanjli wetland Kapurthala, Punjab (India) was investigated for mutagenic potential using Ames fluctuation assay. Most of the soil samples were mutagenic to the strain TA98, irrespective of the presence or absence of S9 mix. The mutagenicity of the samples increased in dose dependent mannerwith maximum effect at 1000 mg/ml of soil extract.
