PM2.5 has adverse effects on human respiratory health as well as on air visibility [2,3]. In the Beijing-Tianjin-Hebei （BTH） region of China, haze has become especially serious in recent years because of industrial expansion and traffic-related emissions [4,5] （http：//news.xinhuanet.com/english/2016-01/07/c_134987525.htm; http：// news.cenews.com.cn/html/2016-01/07/content_38614.htm）.
