ACT Health advises that air quality has deteriorated due to atmospheric dust. People who are sensitive to air pollution, such as those with heart or lung conditions, are encouraged to minimise vigorous outdoor exercise during this period and take their medication as prescribed by their doctor. Anyone experiencing difficulty breathing, should seek medical attention. Dust levels can vary over short time periods (compared to smoke or other pollutants). Information about the health risks of dust and measures people can take to protect their health can be found on the ACT Health website.
