The problem of anthropogenic pollution of the water environment by perchlorate (Pch) and its effect on the human health is discussed in the papers. Also, the physical-chemical methods of Pch determination, which can be used for analyses in various waters, are critically considered. The results of pilot researches on the content of studying Pch in drinking and natural waters in Kiev and some other regions of Ukraine are shown. The comparative assessment of determining Pch by indirect method of atomic absorption (AAS) and method of ion-exchange chromatography (IX) is given. The average content of Pch exceeded the ЕРА standards by 4-400 times in Kiev area and by 12-23 times in other regions of Ukraine. The preferential contamination of the water with Pch in the wells was determined. The high content of Pch in natural water of eastern regions of Ukraine was revealed. The obtained data can be used for revising hygienic standards for Pch in the drinking water.

Key words: perchlorate, physical-chemical methods, drinking and natural waters.
