Sydneysiders experienced 81 days of hazardous, very poor or poor air quality last year, more than the combined total for the previous 10 years, and health experts say new policies are needed for this unprecedented length of exposure to bushfire smoke.
Last year was the first time since at least 2009 that the city has had more than 18 days in a calendar year when the air quality reached poor, very poor or hazardous levels, aThere have already been 14 such days this year."The danger is now, especially if a prolonged bushfire season happens next year and into the future," Sotiris Vardoulakis, professor of global environmental health at the Australian National University said.
At its worst point last year, the air quality index reached 790 in Rouse Hill on November 19, nearly four times the threshold for hazardous conditions. In comparison, the air quality index for Beijing peaked at 175 on Thursday. "We need to reconsider air conditioning and air filtration in the school environment and make sure that facilities are well-equipped to protect [people] from smoke," Professor Vardoulakis said.

pallavisinghal Just as the greenie ideologues planned it when they deliberately prevented fire hazard preparations. They cynically knew they could use ‘emergency’ to sucker more sheeple into bleating for ‘govt’ to do something about ‘climate’ hoax. We see you all, including SMH, ABC, CSIRO, BOM
