Abstract

The environmental study, carried out in the Lublin region, was aimed at assessment of strawberry fruit quality based on the contents of heavy metals (Pb, Cd, Ni, Zn, Cu, As, Hg) and finding correlation between these heavy metals and some properties of soil and plant. Heavy metals in soil and fruits were determined with ASA method, other analyses according to research procedures of the laboratory of the Regional Agrochemical Station in Lublin. Region of cultivation has no significant effect on the contents of heavy metals in strawberry fruit. Some soil properties have significant effect on occurrence of mainly zinc and mercury and, to a slightest degree, also cadmium and copper in the plant. In the fruits, contents of copper and zinc and, to a slightest degree, also cadmium, nickel, mercury, and lead were dependent on occurrence of other elements in this part of the plant. The average contents of heavy metals in strawberry fruit grown in the Lublin region (0.023 mg Pb, 0.020 mg Cd, 0.091 mg Ni, 1.228 mg Zn, 0.358 mg Cu, 0.0015 mg As, 0.000 11 mg Hg kg-1 of fresh matter) indicates that it did not exceed upper threshold of products of this type.
