摘要：The article presents the evaluation of the influence of the heavy metals content in the water from selected Strzelin Quarry Lakes located in Central Europe) on the possibility to use the water for irrigation. The guidelines provided by FAO and in PN-84/C-04635 were the basis of the evaluation. The water pH ranged from 7.1–9.0, on average 7.8. The zinc content was in the range from 0.40–29.00 µg·dm-3, on the average 14.40 µg·dm-3, while the content of copper ranged from 0.00–50.10 µg·dm-3, on average 21.13 µg·dm-3. The cadmium content fell into the range from 0.00–5.50 µg·dm-3, on the average 0.83 µg·dm-3, and the lead content ranged from 0.00–18.10 µg·dm-3, on average 3.16 µg·dm-3. The chromium content ranged from 0.00–21.00 µg·dm-3, on average 4.26 µg·dm-3 and, finally, the content of nickel ranged from 0.00–39.80 µg·dm-3, on average 6.70 µg·dm-3. The values of the analysed heavy metals were similar to the concentrations noted in natural lakes and artificial water reservoirs. As far as the heavy metal content is concerned, the water from the selected Strzelin Quarry Lakes met the requirements that allow using it for the purposes of agricultural irrigation.
