摘要：Environmental pollution by heavy metals and persistent organic pollutants is an actual and serious problem. Hexachlorocyclohexane (HCH) similarly to other POPs can be released from dangerous refuse dumps, old stocks of agrochemicals and pesticide producers or by soil erosion. HCH in low concentrations was determined in both in streams and groundwater’s near to dangerous refuse dumps. Phytoremediation is one of the most environmental friendly techniques to remove POPs from the soils. Its success is dependent primarily on the selection of appropriate plant species tolerant to high concentrations of toxic compounds and producing high amount of biomass. Exposition to toxic compounds is connected to complex reaction based on proteomic changes. In this work the possibilities of mathematical processing of SDS-PAGE electroforeograms of protein extracts of maize (Zea mays L.) exposed to beta-hexachlorcryclohexane in concentrations 0, 10, 25 and 50 ng/l for 12 days are shown
