Abstract
This work devoted to the assessment of the current level of the contamination with polychlorinated biphenyls (PCBs) in environmental objects of the city Ust-Kamenogorsk in Kazakhstan. Particularly, the territory of former Capacitor Plant in Ust-Kamenogorsk and surrounding area were explored and samples of soil, bottom sediments, water, vegetation and fish were sampled from these places. The chemical-analytical studies of PCB contamination were carried out using gas chromatography-mass spectrometry, electrochemical impedance spectroscopy.
