2 Risk assessment and remediation of contaminated land and water environments—case studies

Soil samples were collected directly after mixing the materials in field and transported to laboratory for phytotoxicity test with dwarf beans (phaseolus vulgaris) (Vangronsveld and Clijsters, 1992), soil pore water analysis and the bioaccessibility test (Juhasz et al., 2009). Soil pore water was collected the third day and the fourteenth day of the phytotoxicity test to assess the element availability in soil. The pH and EC were measured immediately after the sampling on a small aliquot of the sample. The remaining volume was stored at 4°C until element concentration analysis using ICP-OES.
