THE CONTENT OF LEAD IN SOILS OF ALLOTMENT GARDENS IN ZIELONA GORA, POLAND

摘要

Lead, as a heavy metal, is harmful to living organisms (both plants and animals) and it is relatively mobile in the environment. In this article we present the results of the monitoring of the lead content in local allotment gardens (Zielona Góra, Poland). We examined both the total and the phytoavailable form. Soil samples were collected in eight places in the allotment gardens, and two places in the neighbourhood of the allotment gardens. The lead content in the soil met the Polish soil ground standards (Regulation by the Minister of the Environment of 9.09.2002). The total content of lead varied from 21 to 39 mg kg1, (12-14 mg kg~(-1) at reference point) and the form potentially available for plants from 10 to 19 mg kg~(-1) (6-7 mg kg~(-1) at reference point). The content of lead does not exceed the threshold values according to Polish law.
