This work presents the results of investigations of cytogenetic changes produced by pollutants of a water ecosystem (phenol, decamethrine, Malathion, Neguvon and crude oil). The changes have been measured by observing frequency of chromosomal aberrations in the tissues of gills and kidney of rainbow trout exposed to pollutants. The fish were exposed to two dose levels of the pollutants, the lowest being the legislative maximum permissible concentration in the waters of Yugoslavia, which were used as a dose‐response for the highest investigated concentrations. Exposure to the water polluted by chemical pollutants under investigation, raised the frequency of aberrations compared to the controls.
