2012年6月16—22日,北京及周边地区出现了一次霾及光化学烟雾复合重污染事件.在这次污染事件中,首先由特定的气象条件引发光化学污染,主要表现为臭氧严重超标,进而通过气粒转化等作用导致PM2.5快速积累,并引起能见度下降.

@@@@There was a combination of photochemical fog and haze during 16-22 June 2012 around Beijing. In the episode, meteorological conditions played an important role in photochemical pollution, which showed high ozone concentration. PM2.5 was accumulated by gas-particles conversion and led to low visibility.
