Abstract
Road runoff in rainy days is assumed to include sediment having organic compounds originated from mobile exhaust. We evaluated genotoxicity and ecotoxicity of these compounds by using bacterial assay umu-test, growth inhibition test with algae and acute toxicity test with Thamnocephalus.
The effluent from a sewage treatment plant receiving runoff water and runoff from a road in the rainy days were collected. The elute of their particulate and dissolved portions were found to have geno- and ecotoxicity. These toxicities were also found in dust in a collector of tunnel and on the road sediment.
