ABSTRACT
The contents of cadmium, lead, zinc and copper were determined in 64 samples of produce (19 strawberries, 16 tops of parsley, 16 dills, 13 lettuces). The produce was gathered directly from home-gardens located near Opole, Wroclaw, Legnica and Jastrzebie Zdroj. The content of cadmium found was within the limits 0.0027–0.663 mg/kg. The contents exceeding the allowable value were found in three samples of dill. The determined quantity of lead ranged from 0.0047 mg/kg to 0.588 mg/kg and the exceeding of allowable contents was found in two dill samples, two lettuce samples and one parsley (greens). The level of zinc contents was between 0.716–34.76 mg/kg. In fourteen samples (3 parsley, 2 lettuces and 9 dills) the limits established before 2004 were exceeded.The contents of copper in produce was within 0.342–17.03 mg/kg. In seven samples (3 parsley and 4 dills) the allowable quantity of Cu established before 2001 was exceeded. The highest amount of cadmium and copper was determined in samples taken near Jastrzebie Zdroj, while the largest quantity of lead and zinc was found in the produce collected in Legnica. The relatively smallest quantities of metals were found in the samples collected near Opole. A comparison of collected data with those available in the literature shows that the recorded level of contamination of the tested produce with heavy metals is close to levels determined for other industrial regions of the country but higher than the world’s standards.
