Evaluating hazardous air pollutants in Australia.
Hazardous air pollutants (HAPS) have been evaluated for their health and environmental significance on a targeted and campaign basis in Australia until recently. Individual States and Territories have been undertaking targeted monitoring studies and have numerous control strategies aimed at controlling HAPS emissions with the focus largely on volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and selected heavy metals, with some limited work on exposure assessment. There has been little evaluation of the potential health or environmental effects of the monitored concentrations of these substances and few toxicological or epidemiological studies have been conducted-none in the community setting in Australia. Moreover, there has not been an agreed method for assessing risks from HAPS in ambient air, with different jurisdictions utilising different international benchmarks. Recently, the National Environmental Health (EnHealth) Council commenced developing a risk assessment methodology, which is being used in the development of ambient air quality guidelines for selected HAPS in Western Australia. In 1999, the Commonwealth Government established the Living Cities-Toxics Program, designed to assess the state of knowledge on HAPS in Australia with the aims of identifying and prioritising HAPS, identifying information gaps and informing the development of national air quality standards and national management strategies. The Commonwealth Government commenced a number of projects in 2000 to progress these aims.
