Ms STEGGALL (Warringah) (14:17): My question is to the Minister for Health. There's currently a proposed revision of the National Environment Protection (Ambient Air Quality) Measure to strengthen the ozone, nitrogen dioxide and sulphur dioxide national standards. Children are most vulnerable to air pollutants, as are the very frail and elderly and asthmatics. The recent Infrastructure Australia audit report found that Warringah has some of the most congested roads in Australia and that there's no regular air quality testing to notify us of the pollution and health risks caused by congestion. Health experts are recommending the expansion of the network of monitors, with daily monitoring of key pollutants and adoption of a much stricter national standard for ambient air pollution. Will you as health minister endorse these stricter health based standards for air quality?
