Phthalates - widespread occurrence and the effect on male gametes. Part 1. General characteristics, sources and human exposure.
Phthalates are widely present in human environment. Widespead exposure to those agents, which are compounds of numerous daily use products, is unavoidable. In the current paper following phthalates benzylbutyl phthalate (BBP), di- n-butyl phthalate (DBP), di(2-ethylhexyl)phthalate (DEHP), diethyl phthalate (DEP), di-isononyl phthalate (DINP) are described. Phthalates mainly enter to the composition of plastic goods, like boxes and containers for storage of foods, toys, medical devices, and also cosmetics, personal care products, as well as paints, vanishes, printing inks. This paper describes the occurence of individual phthalates in the environment (water, air) and in different products. During production, transportation, manufacturing of goods and improper disposal, phthalates released into soil, water and air. For example indoor air included 13 mg/m3 phthalates, where 72 % of all constitutes DEP (2.29 mg/m(3)), BBP (3.97 mg/m(3)) and DEHP (2.43 mg/m(3)). Exposure to phthalates take place mainly by ingestion or inhalation air or through the skin. Presence of phthalates were observed in numerous food products and is connected with migration of those compounds from food storage containers to preserved food. They could mirgate to salivia during sucking and chewing of toys and this way increased exposure to of children. The results of studies regarding to concentration of phthalates in human tissues and excretions are also described. The level of phthalates were measured in numerous of human biological samples. For example, DEHP, DEP and DBP were detected at levels of 5.71 mg/L in blood serum, of 0.30 mg/L in semen and of 0.72 mg/kg in fat samples.
