In this paper the contemporary state and the use of voltammetric methods for the determination of organic toxicants on the modified electrodes are shown. A review of works on the application of voltammetric methods for the analysis of environmental objects - water (natural, drinking, waste, etc.), published in the last 5 years, has been made. The main trends in electroanalytical control over the content of toxicants in the waters are noted. The experimental results on the expansion of determined organic toxicants are represented
