Concentrations and composition of polycyclic aromatic hydrocarbons in the granulodensimetric fractions of soils in Moscow parks

A comprehensive study of the contents and composition of 15 compounds from the group of polycyclic aromatic hydrocarbons in granulodensimetric fractions of soddy-podzolic soils was performed. The specificity of the accumulation of these substances in the clay (heavy-weight) and light-weight soil fractions was investigated. The levels of the soil contamination in Moscow parks with polyarenes were determined, and the assessment of changes in the degree of the soil contamination over a long period of time was made.
