Commercial sap-displaced UK grown Scots and Corsican pine, and Sitka and Norway spruce poles were exposed in a field site at Dundee, Scotland and radial distribution profiles of CCA monitored prior to implantation and after subsequent field exposure. Results show that groundline levels of all preservative elements were higher after 1 and 2 years field exposure compared with those recorded prior to pole implantation. In addition, chemical analyses of the soils at the groundline regions of the poles showed that raised metal levels were detectable. Some of the implications of the results are discussed.
