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.
