Landscape fragmentation and park landscaping as factors of accumulation heavy metals in birch leaves

Heavy metals attract an attention of research workers as indicator of envi-ronment statement. Urban areas as well as industrial area are studied. The article solves the problem of an evaluate of influence on heavy metal contents two typical for city factors. They are fragmentation and park landscaping. As samples birch leaves have been collected in districts Chimky, Mytishi and Zaraysk in 2018. Each point of a collect of samples was a part of unfragmented areas (UFA), e.g. a common area which was limited to buildings and roads. Metals have been defined by atom-absorption method. The analysis was carried out using Multiple Linear Models. The concentration of each metal was a dependent variable. The character of vegetation cover (forest or park), distance to source of pollution and geometric dates were as independent variables. The results showed an important all predictors especially distance to source, the character of vegetation cover, and area.
