Heavy Metals in Soil solution of lowland Oak Forest in Croatia

The following heavy metals were monitored: lead (Pb) copper(Cu), zinc (Zn) and cadmium (Cd). Sampling is performed by means of funnels (throughfall) and the amount of precipitation is measured in rain gauges with a surface opening of 60 cm2. Rain gauges and funnels are placed diagonally by 6-9 items, each on 30x30m plot. On a control plot, where the impact of vegetation is excluded, funnels (bulks) were placed in a random order or circularly. Plastic zero tension lysimeters are placed in the soil at the depth of 20 cm or beneath the humus layer. They collect the seeped liquid (seepage) in the soil. Sampling is 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) in comparison to control samples in the open area.
