Influence of CCA-treated pine structures on the arsenic content of soils in preschool playgrounds near Melbourne, Australia
2008
Cookson, Laurie J.
The arsenic content of soil was determined in three playgrounds at Healesville, near Melbourne, that contained copperchromium-arsenic (CCA)-treated pine structures. The highest background arsenic content of Healesville topsoil and subsoil was 9.1 and 14.6 mg/kg ovendry basis, respectively. The mean arsenic content found near CCA-treated pine was mostly similar to the control samples, although the highest reading obtained was 23.9 mg/kg. Highest arsenic contents in control samples from Warrandyte, a site 30 km from Healesville, were 31.7 and 46.4 mg/kg for topsoil and subsoil respectively.
