Phthalates — questions of biotoxicity for the human body

Resume

The review presents the biomedical effects of polyvinylchloride plasticizers — phthalates, the most frequently used in everyday life of a modern human. These chemical components of plastic are now recognized as global environmental pollutants because of their ability to actively migrate. The widespread industrial, household use of phthalates, including the use in the medical field, in particular di-2-ethylhexyl phthalate, results in daily human exposure through parenteral absorption, inhalation and dermal contact. Numerous experimental and clinical studies have shown that phthalates possess antiadrogenic, anti-estrogenic and antithyroid properties, lead to defects in neurodevelopmental and behavioral abnormalities, impairment of sexual differentiation, and the formation of reproductive anomalies in the most sensitive stages of development: fetal > pubertal > adult (mature). Phthalates increase the risk of development of reproductive problems and the formation of hormone-dependent tumor transformation. They are a factor in the genesis of diabetes mellitus, obesity and are associated with the development of respiratory diseases, various immunodeficiency conditions, allergies and asthma. Phthalates contribute to the formation of the pathology of the endocrine, broncho-pulmonary, cardiovascular systems and the gastrointestinal tract, being the trigger of oxidative stress and inflammatory reaction. Nowday genotoxic effects of phthalates are proving, which is the substantial basis for cancerogenesis.
