Accumulation features of some chemical elements, typical for contaminated urbanized areas, including a cluster of heavy metals and sulphur compounds, were studied in some structural stand elements of three types of pine phytocenoses. Investigations were carried out in plantations functioning in the zone of industrial pollution and in typologically homogeneous communities of the same age class (60 years) located in a reserved area. Coefficients of biological absorption were determined as the quotient of the number of elements in forest litter and the average weighed content of them in the root layer of soil
