Environmental Context.In some agricultural areas, soils are contaminated by trace elements. This contamination of cultivated may constitute a serious problem for human health through the accumulation metals in edible parts crops. In order to assess risk associated with metal soil, we need develop simple tools like Diffusive Gradients Thin Films (DGT) predicting crop accumulation. The present study focuses on an site fallout from industrial dust and reveals that DGT could be predictive tool zinc lettuce. Abstract.Risk assessment needs address phytoavailability. technique diffusive gradients thin films has been shown promising phytoavailability wide range soils. examined ability method predict within site. Lettuce (Lactuva sativa cv Appia) was grown nine metal-contaminated differing mainly their pH. Metal concentrations (Zn, Cd) plant shoots were compared total soil free ion pore waters, effective concentrations, CE, measured DGT. Plant Zn highly related suggesting can sensitive able mildly Cd less closely signifying processes other than re-supply solid phase occur during soil–plant transfer Cd.
