This project quantifies the emission of dioxins and biphenyls in burning of treated and contaminated wood to provide data on whether combustion of such materials should be regulated in Australia and whether an educational campaign needs to be mounted to make public aware of this problem. For example, our preliminary results indicate that, timber treated with copper boron azole, a non-arsenic replacement for CCA preservative, produces extremely high levels of dioxins, both in flames and in the ash. If the preliminary results are confirmed, this agent must be disallowed as a wood preservative in Australia, as it poses unacceptable risks to the Australian population and environment.

该项目对经处理和受污染的木材燃烧过程中二恶英和联苯的排放量进行量化，以提供数据，说明澳大利亚是否应管制此类材料的燃烧，以及是否需要开展教育运动，使公众认识到这一问题。 例如，我们的初步结果表明，用铜硼唑（一种不含砷的CCA防腐剂替代品）处理的木材，在火焰和灰烬中都会产生极高水平的二恶英。 如果初步结果得到证实，澳大利亚必须禁止该制剂作为木材防腐剂，因为它对澳大利亚人口和环境构成不可接受的风险。
