Concentrations of heavy metals, which have well-known toxic character, are often higher in urban soils than those in agricultural soils, reflecting several metal inputs arising from human activities. Among urban soils, garden soils have a specific function and significance. Gardens are traditionally devoted to cultivation of vegetables and fruits. Therefore, the urban hobby gardens and the urban vegetable gardens can be potential risky for people since unknown amount of heavy metals can be accumulated into organism of local residents due to consumption of home-produced vegetables and fruits. Our aim is to evaluate degree of heavy metal contamination in the garden soils and to determine metals enriching in the topsoils and their potential sources. Thus, the garden soils in detached houses (43 pieces) on the outskirts were studied. The studied gardens can be categorized into vegetable, fruit, flower ones. The total metal content (As, Co, Cr, Cu, Ni, Pb, Zn) was measured using an ICP-OES technique following a full digestion with aqua regia. Our results demonstrate that the increased metal concentration are typical of the urban garden soils but metal concentrations exceeding the limit value can be observed only in the case of As, Cd, Cu. In accordance with the enrichment factors, it can be established that Cu, Zn, Pb have accumulated in more significant amount in the garden soils, whereas As, Co, Ni and Cr can be considered to be geogenic since they have not accumulated in the garden topsoils.
