[Biological screening of the level of anthropogenic environmental pollution and its hazard for the health of the population].

A possibility was examined to use a screening cytogenetic method for calculating micronuclei in frog blood cells as an indicator of the degree of environmental pollution and its hazard to human health. Data obtained correlate with an increased rate of reproductive function disorders in women and congenital malformations in children, living in regions where the cytologic studies of biological objects were carried out. The informational value of biogeochemical screening with the use of test objects for the assessment of the region ecological imbalance is stressed.
