Air Qual­ity

Beijing Review - - This Week -

The den­sity of fine par­tic­u­late mat­ter (PM2.5) in Bei­jing de­creased by 10.1 per­cent year on year in the first nine months of 2016, the lo­cal en­vi­ron­ment watch­dog said on Oc­to­ber 18.

The av­er­age PM2.5 read­ing in the pe­riod was 62 mi­cro­grams per cu­bic me­ter, the city’s en­vi­ron­men­tal pro­tec­tion bureau said. In 2015, the level was 80.6 mi­cro­grams, down from 95.7 mi­cro­grams in 2012.

Air qual­ity was rated ex­cel­lent or good for 155 days, 17 days more than dur­ing the same pe­riod last year. Heavy air pol­lu­tion oc­curred on 15 days, four fewer days than in the Jan­uary-Septem­ber pe­riod last year.

Mean­while, the den­si­ties of PM10, sul­fur diox­ide and ni­tro­gen diox­ide dropped 14.9 per­cent, 28.6 per­cent and 6.7 per­cent, re­spec­tively.

Over the past three quar­ters, Bei­jing com­pleted im­prove­ments on coal-fired boil­ers, elim­i­nated 306,000 ag­ing au­to­mo­biles and phased out 224 polluting fac­to­ries.
