The application of mixed waste organic output (MWOO) to soils: Effects on metal and metalloid concentrations, distribution, bioavailability and mobility in NSW soils

Abstract

Mixed waste organic output (MWOO) has been used as a soil amendment for many years. However, concern regarding the introduction of contaminants to soil ecosystems can potentially restrict its use and there is growing need to fully understand the risk associated with utilizing this potentially beneficial resource, in particular with regard associated metal and metalloid contamination. The aim of this project was to examine the impact of MWOO application on concentration, distribution, bioavailability and mobility of seven targeted priority pollutants including As, Cd, Cr, Cu, Ni, Pb and Zn on different soils of NSW.
