Beijing’s neighbor Tianjin released its air pollutant analysis at the weekend, in which dust pollution was blamed as the main cause of smog.
About 100 kilometers from China’s capital, Tianjin is the second city to release the analysis of its fine particular matter, or PM 2.5 — airborne particles smaller than 2.5 microns in diameter.
Early this year, China’s environmental authority had asked the 30 municipalities and provincial capital cities — excluding Lhasa — as well as five big cities to release analysis before the end of 2014.
“By analyzing the pollutants, we can take different measures specifically in different areas to curb smog,” said Feng Yinchang, a professor with the College of Environmental Science and Engineering who oversees the research.
According to the Tianjin analysis, about 30 percent of the air pollutants was dust. Coal burning, motor vehicle exhausts and industrial production accounted for 27 percent, 20 percent and 17 percent respectively.
