Bei­jing to raise thresh­old for pol­lu­tion ‘red alerts’

China Daily (Canada) - - NEWS CAPSULE -

Bei­jing will raise the thresh­old for is­su­ing its high­est air pol­lu­tion warn­ings, the state news agency Xin­hua re­ported, two months af­ter smog trig­gered the city’s first ever “red alerts”.

In fu­ture, the high­est alert will only be is­sued when the daily av­er­age air qual­ity in­dex (AQI) is fore­cast to ex­ceed 500 for a day, 300 for two days in a row or 200 for four days, Xin­hua re­ported, cit­ing Bei­jing’s en­vi­ron­men­tal pro­tec­tion bureau. Now a red alert is is­sued when the AQI is fore­cast to ex­ceed 200 for at least three days.

Schools were closed and out­door con­struc­tion work was sus­pended when thick smog prompted Bei­jing to is­sued its first red alert last De­cem­ber.

China’s cap­i­tal also will al­most dou­ble the num­ber of air mon­i­tor­ing sta­tions to give a bet­ter idea about the true state of the city’s air qual­ity, Xin­hua said.
