abstract:
In the winter wheat cultivation areas in the Lublin region, samples of grain and soil were collected for analysis. The study was aimed at assessment of winter wheat grain quality based on the contents of heavy metals (lead, cadmium, nickel, zinc, copper, arsenic and mercury) and finding the correlation between these heavy metals and some properties of soil and plant. Heavy metals contents was not significantly dependent on the soil on which the plant was grown. Dependence of the contents of these metals in grain on some soil properties was slight and often of a random character. This is indicated by statistical calculations that show that determination coefficients were within the range of 4.3-38.5%. Occurrence of particular heavy metals in wheat grain was dependent to a slight degree on the contents of other analysed elements in that part of the plant. This is indicated by performed statistical calculations and, in particular, by the determination coefficients that were within the range of 10.3-25.1%. Average contents of heavy metals in winter wheat grain (0.106 mg Pb, 0.062 mg Cd, 0.425 mg Ni, 24.2 mg Zn, 2.94 mg Cu, 0.007 mg As, 0.0003 mg Hg kg-1 of fresh matter) indicate that their level was low and did not exceed upper threshold of contamination typical of products of this type.
