It has been proved the particularity of population is a critical factor in ensuring the adaptive-compensatory responses of antistress systems to the impact of unfavorable factors, whereas the response of specific markers of toxicity adequately distinguished the effects of physical and chemical factors. Changes in antioxidant system status were grounded in oppression of its activity in the digestive gland of pulmonary mollusk and activation, especially in the gills of swan mollusks from contaminated waters. In mollusks from the contaminated areas the signs of cytotoxicity and activation of anaerobiosis, as well as from clean waters - reducing activity of glutathione were shown. Under effects of chemical factors an increase of metallotioneines content in gills tissue, activation of microsomal monooxygenase, cholinesterase, increased estrogenic activity were noted.
