Air toxics include benzene, dioxins, lead and other metals. Major sources of these toxics include motor vehicle exhaust and some commercial and industrial processes. Knowledge of the health effects of air toxics is far from complete, but studies in Europe and North America are showing that very small amounts of air toxics may present a risk to human health and the environment.
Results of OEH monitoring to date indicate that levels of air toxics in the Sydney, Newcastle and Wollongong areas are generally low in comparison to comparable cities in Europe and North America.
For information about air toxics see:
- Ambient Air Quality Research Project (1996-2001) - With international concern turning to air toxics, which may be affecting human health and the environment through low level exposure over the long term, the NSW Government provided $1.4 million for an investigation into concentrations of these pollutants in the air in NSW. A summary report and four internal working papers are available on this research project.
- State of the Environment: The 2012 report is the most comprehensive and accessible report available on the NSW environment:
