Abstract

Soil pollution and accumulation of heavy metals in the most com­ mon vegetables were investigated in the Salek Valley, where the largest Slovenian thermal power plant of Sostanj (STPP) is located. Methods were chosen according to international and Slovenian standards. Heavy metal content in soils and plants was determined by ICP-MS, ETAAS and hydride technique after appropriate diges­ tion of samples. Results revealed that garden soils in the Salek Valley are not pol­ luted in general with heavy metals. On the contrary, some plant species exceeded permitted levels of Cd. Our results showed that the most sensitive group of plants are still affected, although emissions of heavy metals markedly decreased after the desulfurisation device was built at the STPP.
