abstract:
In an environmental study carried out in the Lublin region in 2001-2003 cucumber 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 the ASA method. No significant influence of the plantation location in the Lublin region on the contents of heavy metals in cucumber was found. Contents of zinc and cadmium in cucumber depended most on some soil properties, contents of mercury, copper and lead – less, and nickel and arsenic – in the least degree. Contents of copper, cadmium and zinc in cucumber depended on indicated elements in the greatest degree, contents of mercury and nickel – less, and arsenic and lead – the least. Average contents of heavy metals in cucumber (0.013 mg Pb, 0.007 mg Cd, 0.141 mg Ni, 1.84 mg Zn, 0.336 mg Cu, 0.005 mg As and 0.8∙10-4 mg Hg per kilogram of fresh matter) indicates it was low and it did not exceed the norms.
