In order to establish the current status and assess the impact of agriculture in the area planned to be included into the envisaged environmental network, we analyzed the arable soil, pasture soil and sediments for the content of heavy metals. Out of a total 38 analyzed soil and sediment samples, only 2 were found to contain heavy metals in concentrations higher than the MAC for agriculture soil. An increased concentration of copper (189.1 mg/kg) was recorded in a sample of vineyard soil and increased nickel concentrations were recorded in one sample of pasture soil (60.9 mg/kg). Further research showed that the high Ni concentrations were of the geochemical origin, while the high Cu was of anthropogenic origin. Out of a total 10 sediment samples analyzed according to Dutch criteria for threshold values, increased concentrations of Cu and Zn were found in one sample, and high concentrations of Ni were found in 4 samples. At the same time, the heavy metal contents in the analyzed sediments were much below the anticipated remediation values.
