For the first time dioxins (including 2,3,7,8-tetrachlorodibenzo-p-dioxin, TCDD) were revealed by high resolution chromatography-mass spectrometry in tissues of animals (rodents and fish) and abiotic samples (soil, sediment, snow) from the biotopes near the landfill with solid wastes ("Salariyevo", New Moscow). Profiles of congeners in soil samples, snow and sediment were well comparable. Parameters of "toxic equivalency quantity" (WHO-TEQ98) greatly exceeded the levels registered in Vietnam dioxin-contaminated areas (territories of ecocide) known to produce a so-called dioxin pathology among population. As to the MPC for soil the observed levels near landfill were almost 38 times higher than the standards set in Russia. The consequences of the pollutants influence on the state of animals reflected the manifestations of toxic effects on the whole organism and the chromosome apparatus, in correlations with the parameters of dioxins (WHO-TEQ98) and/or TCDD in their tissues and objects in their natural habitat. Changes of cytogenetic status of fish and rodents, morphometric parameters of fish age dynamics, the emergence of individuals with abnormal head structure - correspond to pathological processes and conditions that determine the pathogenesis of human dioxin pathology. Analysis of the data obtained illustrates the possibility of creating a universal methodical approach for screening the hazards of dioxins' low dozes for human health.
