The Effect of Compost and Fly Ash Treatment of Contaminated Soil on the Immobilisation and Bioavailability of Lead

The study discusses changes in lead contents soil and crops after application of compost fly ash. A three-year experiment was conducted on narrow-leaved lupine (Lupinus angustifolius L.), camelina (Camelina sativa L.) oat (Avena which were grown medium fertilised with or ash (FA). amounts various combinations evaluated using sequential (BCR analysis) single (DTPA solution) methods. total selected macronutrients assessed the biomass plants. Pb plants used to calculate risk assessment code (RAC), individual contamination factor (ICF), bioconcentration (BCF) coefficient level (CCL). Lower bioavailable observed as a result FA application. Fly immobilised more effectively, evidenced by BCF CCL values. increase sequentially separated fractions plant caused applied FA. exchangeable forms decreased, whereas its residual increased.
