|We applied in vitro assays using cultured cells for the ecotoxicological assessment of various samples collected from the environment. The results of cytotoxicity assays on water samples from rivers and cooling towers correlated well with the respective water analyses.|
However, some samples induced different responses between the two cell lines employed. Extracts of solid samples revealed the order of contaminations in the phototoxicity test and mouse lymphoma mutation assay. Therefore, the in vitro toxicological assays were useful to screen test samples from the environment composed of various pollutants.
