A bulldozer demolishes synthetic sports fields at the Baiyunlu campus of Beijing No.2 Experimental School in Xicheng District, Beijing, June 17, 2016. Many students suffered from nosebleeds, dizzy spells and coughs after running on the track last month. Local authorities announced on June 12 that tests showed the sports fields and air quality met state standards but some parts of the playground will be demolished. The school will reopen on next Monday. (Photo: China News Service/Jin Shuo)
