Abstract

The study was conducted on 150 farms that grow oriental tobacco from three well known tobacco regions in Macedonia (Pelagonia, Southeastern Region and Vardar Valley). The total content of lead in soil samples was measured through decomposition by HF, HClO, and HNO acids. A solution of 0.005 mol/L diethylentriaminepentaacetic acid (DTPA) and 0.1 mol/L triethanolamine at pH 7.3 was used for extraction of the element mobile form from soils. The digestion of plant samples was made with HNO and HO using microwave digestion system. Atomic emission spectrometry with inductively coupled plasma (ICP-AES) was used for the determination of Pb content in the soil and plant samples. A correlation analysis was conducted between pH, organic matter content, total and mobile form of lead in the soil, and the concentration of this element in different organs of tobacco.
