摘要：Extractable contents of heavy metals such as Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb and Bi in soil and plant tissue samples (fruit, leaf, twig and root) collected, along
shootsa distance of 1100 m to the West, from the surroundings of a metallurgical factory producing mainly zinc, cadmium and lead were determined by flame atomic absorption spectrometry (FAAS). In addition,
datastructurethe determinations of Ca and Mg, macro nutrient elements for plants, were also performed. Three extractant solutions were ud for dissolution of soil samples, namely aqua regia (1 HNO3+ 3 HCl) for total metal analysis, 1 mol L1 ammonium 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 HNO3 and HClO4 was ud to analyze the fruit samples. The analys of the leaf, the twig, and
