An air pollution alert has been issued for Sydney residents as ozone levels continue to rise beyond government standards.
New South Wales Health said the ozone excess, which causes “poor” air quality on Tuesday, could affect people with respiratory conditions.
Ozone is a pungent gas resulting from chemical reactions between atmospheric gases and nitrogen oxides from car-vehicle exhausts, which can cause chest pain, coughing and throat irritation when inhaled. Hot weathers could exacerbate ozone pollution levels, a statement by NSW Health said.
Dr Ben Scalley, Director of Environmental Health Branch at NSW Health said parents are advised to keep watch on their children when ozone levels are high.
“Ozone levels are higher outdoors than indoors, so parents should limit the time their children with asthma play outside as they are more susceptible to the effects of ozone pollution,” said Scalley.
Scalley reminded that people should remain alert to the link between high temperatures and ozone pollution.
