An evaluation of the mutagenic background and mutational variability of the population in a region with a high intensity of pesticide use

: The mutagenicity of soils (on A. cepa and Tr. poludosa) and chromosome aberration level in population have been studied in two Uzbekistan areas. The obtained results are evidence of global contamination of the whole region by mutagenic and toxic chemicals. The mutation level in test objects and frequency of chromosome aberrations in peripheral blood lymphocytes in the examined persons have not been correlated. The condition of the area studied is classified by mutagenic contamination as "critical".
