Heavy metals in soil solution of lowland oak forest in croatia
The aim of the research is to prove the influence of air pollution on lowland forest and quality of soil solution in forest soils. The following heavy metals were monitored: lead (Pb) copper (Cu), zinc (Zn) and cadmium (Cd). Sampling was performed by means of funnels (throughfall) and the amount of precipitation was measured in rain gauges with a surface opening of 60 cm<2>.Rain gauges and funnels were placed diagonally by 6-9 items, each on 30mX30m plot. On a control plot, where the impact of vegetation was excluded, funnels (bulks) were placed in a random order or circularly. Plastic zero tension lysimeters were placed in the soil at the depth of 20cm or beneath the humus layer. They collected the seeped liquid (seepage) in the soil. Sampling was carried out once a month. According to the obtained data of monitoring, our forests and soils absorb more deposited heavy metals (wet and dry sedimentation) compared to the control samples in the open area.
