Currently, introducing harmful substances into the environment forms a frequently discussed issue. This includes toxic metals that occur in the soil. In the Czech Republic, cultivating your own crops in allotment gardens is a widespread activity. This paper aims at assessing amounts of toxic metals occurring in the soil while determining the basic soil attributes in specific allotment garden areas; the soil include pH, ORP (oxidation-reduction potential) and conductivity as factors for the mobility of metals since such mobility is closely linked to the potential risk of transfer of toxic metals in food chains. The study also includes analysing the measured values against the applicable legal norm in the Czech Republic and identifying the level of soil contamination at specific gardening sites. The XRF analysis was used to determine metal levels in soil samples; the BASS DELTA device was used for this method. Out of the eight specified metals (As, Cd, Cr, Cu, Ni, Pb, V, and Zn), four metals (Cd, Cu, V, and Zn) were found to exceed the legal norms in terms of content. Cd was found to be the most hazardous element within the set with its level reaching 12.69 mg/kg whereas 0.5 mg/kg is provided by the legal norm. It should be noted, however, that considering the detected soil attributes, mobility of metals is expected to be low in the given settings.
