Mobility and bioaccessibility of trace metals in soils assessed by conventional extraction procedures and passive diffusive samplers

Popis výsledku v původním jazyce

The objective of the work was to verify the use of the diffusive gradient in thin films technique (DGT) for assessment of metal mobility and bioaccessibility in soil and comparison of results with classical extraction procedures. Non-contaminated naturalgrassland and arable land soil samples from the South Moravian district, Czech Republic, both homogenized and undisturbed were studied. While DGT applied in soil cores gave information about vicinity of the sampling probe related predominantly to the local structure and heterogeneity of the soil, measurement of mobile and kinetically labile metal species in the soil slurry could provide an approximation of average information on plant accessible metals pools in soils, several orders of magnitude lowerin comparison with results obtained by extraction procedures. The majority of DGT measured metals occurred in low molecular labile forms as demonstrated by using the diffusive gels with different pore size. Concentration of metals measure
