Abstract
Extractable contents of heavy metals such as Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd , Ph and Bi in soil and plant tissue samples (fruit, leaf, twig and root) c ollected, along a distance of 1100 m to the West, from the surroundings of a metallurgical factory producing mainly zinc, cadmium and lead were determ ined by flame atomic absorption spectrometry (FAAS). In addition, the deter minations of Ca and Mg, macro nutrient elements for plants, were also perfo rmed. Three extractant solutions were used for dissolution of soil samples, namely aqua regia (1 HNO3+ 3 HCl) for total metal analysis, 1 mol L-1 ammo nium acetate for exchangeable metal contents, and a dilute acid mixture (0. 1 M HCl in 0.025 M H2SO4) for acid soluble metal contents. A mixture of HNO 3 and HClO4 was used to analyze the fruit samples. The analyses of the leaf , the twig, and the root tissue samples were made by dry ashing method. The detection limits of the metals were in the range of 0.04 to 0.45 mug/mL fo r all soil extracts and 0.01 to 1.50 mug/mL for the fruit samples. The reco very values for all the determinations were higher than 95 %. The results o btained from the analyses of plant tissue and soil samples were evaluated u sing linear correlation analysis and concentration factors to identify the effect of the factory near the grape-vine area.
