Phthalates (PAEs) constitute the primary components of indoor dust pollutants and significantly impact human reproductive health.

Abstract Phthalic acid esters (PAEs) are dialkyl or alkyl/aryl ester derivatives of phthalic acid. PAEs colorless, odorless, and flavorless oily liquids. the main plasticizers used in industry households. DEHP (di-(2-ethyl hexyl) phthalate) is plasticizer polymer industry, whereas DMP (dimethyl DEP (diethyl mainly as solvents fixatives cosmetics personal care products. synthetic organic compounds poorly soluble water but solvents. Into environment, they introduced during production, use degradation, packaging, transportation plastic In degraded three ways: by hydrolysis, photodegradation, microbial biodegradation hydrolysis environment very slow. pollutants soil, water, groundwater, river marine air, sediments, vegetables, biota. Due to great interest subject environmental pollution emergence new information this area, it extremely important systematically review current knowledge. presented paper, occurrence different matrices was reviewed. The toxicity plants, animals, humans also described.
