Chris Eiser from the New South Wales Department of Environment and Climate Change says the pollution readings have been off the charts for much of the day.
"Particles we measured today are the highest we measure since we started monitoring in the 1970s," he said.
"They are certainly far in excess of any levels we measured during bushfires. For example, we're measuring around 15,000 micrograms per cubic metre as a concentration.
"Bushfires would normally get around 500 micrograms per cubic metre and on a normal day that would be anywhere between 10 and 20, so certainly a significant event."
