閱讀下面的材料，然后根據(jù)材料內(nèi)容回答問題。

What is to blame（歸咎于） for the smog (霧霾) hitting China? The question that has bothered people for a long time got an answer recently.

According to Wang Yuesi, a researcher at the Chinese Academy of Sciences (CAS), about 40 percent of PM2.5 pollutants in Beijing are the result of coal (煤炭) burning, from both local and outside the city.

Surrounded by Hebei, a major area for coal burning, about 20 percent of Beijing’s pollutants come from outside the city. And we know there are many steel(鋼鐵) factories in Hebei, too. According to the CAS, each year Beijing burns 23 million tons of coal while Tianjin burns more than 70 million tons and Hebei a huge 270 million tons.

“Coal burning is a primary source of sulfur oxide (SO2, 二氧化硫) which is the primary cause of PM2.5,” said Wang.

The report of the CAS says that in the Jingjinji area (Beijing, Tianjin and Hebei), coal burning is responsible(負(fù)責(zé)任的) for 9 percent of primary particles (顆粒) that make up PM2.5. The coal burning also emits (排放) 69 percent of the total SO2 and 47 percent of nitrogen oxide (氮氧化物), which will greatly concentrate (加強(qiáng)濃度) the PM2.5 particles in the air.

According to the air pollution plan, the Jingjinji area should reduce（減少） its PM2.5 concentration by 25 percent by 2017 from 2012 levels. To meet the standards, the report suggests great cuts in coal use in the area.

“This is a very great goal but it is achievable with cooperation（合作） between cities instead of cities working on their own,” said Wang.
