Abstract
A technique for the direct preconcentration of bis(2-ethylhexyl) phthalate (DEHP) on a reversed-phase analytical column was proposed for the analysis of water samples by high-performance liquid chromatography (HPLC). A proced ure for determining DEHP in surface water and atmospheric precipitations in the laboratory and in the field was developed (the limit of detection is 0 .1 mu g/L, the limit of determination is 0.3 mu g/L, and the relative stand ard deviation is 20 or 6% at a DEHP concentration of 0.3 or 10 mu g/L respe ctively). The concentration levels of DEHP as a chemical tracer for the tra nsfer and migration of air and water masses were examined in Lake Baikal wa ter and in the snow cover of the Baikal region.
