Phtalates in Lithuanian environment and needs for human biomonitoring
Keywords: Phthalates, REACH registration, environmental levels, human biomonitoring
AbstractControlling chemical substances and correct evaluation of danger and risk caused by them, based on scientific research are necessary in order to keep environment and public health safe. Regulation signed by European Parliament and Council to control registration, evaluation, authorization and limitation of chemical substances (REACH) is the main juridical act from the new European Union‘s policy regarding regulation of chemical substances. Objective of this research was to gather and analyze data regarding phthalates used in Lithuania‘s industry, to present data on its environmental levels in surface water, sediments, sewage treatment plant effluents, and to discuss the needs for the human biomonitoring in Lithuania. The amount of diethylhexyl phthalate yielded to Lithuania‘s industry and market, incresed 65 times from 3,7t in 2003 to 240,81t in 2007. DEHP concentrations in Lithuania in wastewater exceeded regulated annual average maximum allowable concentrations up to 27 times and maximum allowable concentrations up to 13 times. High environmental concentrations of phthalates pointed out to the needs of establishment of permanent human biomonitoring in Lithuania.
