Abstract
The article considers the problems of ecotoxicology, in particular, changes of the gonads in both acute and subacute toxicity of industrial dust.Dust complex chemical composition Temirtau has mutagenic effect of time-dependent effects.According to the conducted experimental studies have shown that chronic and acute exogenous intoxications industrial chemical compounds have a direct and indirect influence on the function of the gonads.Study the dust Temirtau, causes moderately expressed changes of spermatogenesis in experimental animals compared to control animals and the violation of the morphological status of spermatozoa.
