In the industrial zone of Obilić the thermal plants “Kosovo A” and “Kosovo B” are located, as well as a heating station, which with their emissions pollute Obilić and its vicinity. Additionally, a daily coal mine, a separation, a drier and a nitrogen fertilizer plant there are placed. This thermo energetic gigant represents a strong source of SO2, smoke and flying dust, as well as products of coal combustion. The goal of this investigation was to investigate, in the area of Obilić where air pollution exists on a higher level, the content of cadmium (which is very toxic) in lucerne and cow milk at different locations and distance from the source of pollution in 6 different localities. By the method of Absorbic Spectrophotometry it has been determined that the average presence of cadmium in the investigated samples of lucerne was 0.07 mg/kg DM and the average value of cadmium presence in milk samples amounted to 0.04 mg/l. The established values exceed regular standards so that in relation to them, milk from these areas should not be used for human nutrition, especially children.
