Total Heavy Metal Status Of Horticultural Soils In Queensland
This study was undertaken to assess contemporary levels of a range of total heavy metal concentrations in a significant representation of Queensland soils subjected to normal horticultural practices. Carefully selected soils from 191 vegetable growing sites from an earlier Queensland wide survey provided an excellent opportunity to undertake this work at relatively low cost. This report details total concentrations of eleven heavy metals, including arsenic, cadmium, cobalt, chromium, copper, mercury, molybdenum, nickel, lead, selenium and zinc, found in horticultural soils. Results from this study were comparable to other published heavy metal data on Australian agricultural soils although in many cases again at the higher end of what is only limited available information.
