Оцінка екологічного стану грунтів територій Сакського Державного хімічного заводу
Paper gives the results of the environmental soils status assessment of Saki State Chemical Plant areas, which stopped operations in 1996-1998, but the area of the plant is covered with industrial waste that had been accumulated over the years of its existence. It was noted that in the analysis of soil samples more than 25 contaminants were found. The effect of the most dangerous toxic substances - heavy metals, in particular relating to the first class of danger: cadmium, mercury, lead, selenium, zinc, arsenic was studied. Ecological condition of the soil and its pollution category was evaluated respectively overall pollution index (Zc), according to the procedure E. Goncharuk. It was established that in some samples pollutant concentrations exceed the established limits by more than 2,4-43 times. It was determined that, according to the methodology used soil contamination belongs to category III (Zc = 38,67), that is dangerous. An increased environmental risk of toxicants was noted and the characteristics of their negative effects on the plants and human were shown. It was proposed to develop project of contaminated soil remediation.
