MOBILITY OF ARSENIC, CHROMIUM AND COPPER ARISING FROM SOIL APPLICATION OF STABILISED AGGREGATES MADE FROM CONTAMINATED WOOD ASH

Popis výsledku v původním jazyce

Stabilized cementitious aggregates (AG) were produced from wood ashes with appox. 10000 ppm As, Cr and Cu, then amended to two agricultural pasture soils. Metal(loid) leaching (column tests), mobility (pore water extracts) and uptake to ryegrass was determined, comparing raw ashes with aggregates. Risk modelling was applied to selected data to inform wider discussion of the experimental results. During prolonged leaching (12d) both aggregates were susceptible to mild dissolution or release of metal(loid)s upon acidification. Pore water sampled from the pot test indicated Cr was generally most mobile, As least so, reduced furthest by AG 2. Risk modelling, based on pot experimental data, demonstrated soil specific accumulation of As in beef muscle and milk, being furthest reduced (compared to the raw ash addition) by AG 2 in soil A, but increased in soil B by the same treatment. The results of this study indicate that a reduction in soluble As, Cr and Cu can be achieved through cementitious aggregation
