Petrochemical products are diverse and include derivatives of both organic chemistry processes of hydrocarbons and synthesis processes – rubbers and polymers. The study of polymer products behavior in the environment is of scientific interest due to the global problem of plastic waste accumulation as a result of anthropogenic activities. Some plastic additives, when degraded, enter the environment, are included in the trophic chains and have a toxic effect on living organisms. The main share of modifying additives is occupied by plasticizers, and among them the most common and toxic for living organisms are additives from salts and esters of phthalic (orthophthalic) acid. The article considers a group of phthalates: dimethyl phthalate (DMPhL), dibutyl phthalate (DBPhL), diethyl phthalate (DEPhL), butylbenzyl phthalate (BBPhL), dioctyl phthalate (DOPhL), bis (2-ethylhexyl) phthalate (BPhL). The results of the qualitative and quantitative analysis of the rivers in Moscow and Moscow region, comparative assessment of the state of objects under study contaminate by phthalates, potential risk assessment and biotesting of samples with the highest concentration of toxic phthalate additives are presented.
