Drosophila as a model for toxicological study is a simple and effective test-system owing to (i) availability of a wide range of accessible methods allowing the integral assessment of the negative effect of the factor under study on the vital characteristics at all levels of the organism vital activity (from molecular to population), (ii) possibility of obtaining results within a relatively short period of time (from 2 days to 2 weeks); (iii) low price of working methods, (iv) absence of specific requirements as t...

Analysis of the air environment and atmospheric emissions is an efficient method for assessing the ecological situation in cities. Assessment of the chemical composition of deposit environments (soil, snow) shows long-term contamination. The snow cover (SC), being a natural accumulating plate, reflects environmental contamination with heavy metals (HM) caused by entry from various sources. The work aims to study the three-dimensional dynamics of large city contamination with HM. Sampling (in 2019 - 100, in 2020-10...
