In an environmental study carried out in the Lublin region in 2001-2003 apple quality was assessed based on the contents of heavy metals (Pb, Cd, Ni, Zn, Cu, As, Hg). Some interdependencies between these metals and some soil or plant properties were evaluated. Heavy metals in soil and plant were indicated with AAS method, other chemical analyses according to the research procedures of the accredited laboratory of Regional Chemical-Agriculture Station in Lublin. No significant influence of the orchard location in the Lublin region on the contents of heavy metals in apple was found. Contents of nickel in apple depended on some soil properties most, contents of copper and cadmium-less and mercury, arsenic, lead and zinc-least. Contents of nickel, zinc, lead, copper and arsenic in apple depended on indicated elements most, contents of mercury and nickel-least. Average contents of heavy metals in apples from orchards of the Lublin region (0.031 mg Pb, 0.0057 mg Cd, 0.182 mg Ni, 0.453 mg Zn, 0.319 mg Cu, 0.00095 mg As and 0.00011 mg Hg per kilogram of fresh matter) indicates it was low and it can be included to human diet without limitations.
