Times dispatch ( reporter Xu Yier Yang Qiwei correspondent ) with rapid process of industrialization, the Pearl River Delta is faced with serious regional atmospheric pollution caused by the decreased visibility problem. Yesterday, the China Meteorological Administration, Guangzhou tropical marine meteorological institute chief expert researcher Wu Dui points out : the current air quality evaluation index already cannot reflect the deterioration of air quality in the Pearl River Delta 's essence, the need for specialized project in-depth study of fine-particle aerosol pollution occurrence and development of the law, to discover the cause of decreased visibility of the main control factors, and then puts forward improved visibility of the control suggestion.

China Meteorological Bureau of Guangzhou tropical marine meteorological institute chief expert researcher Wu Dui points out, some recent research suggests that, regional and local emission pollutant transport in city two respects affect air quality, low visibility, severe particulate atmospheric pollution events often associated with Pearl River Delta regional fine-particle aerosol haze appeared on lead. Wu said the public complaints against, the" visibility deterioration and the current air quality evaluation system, the contradiction between" is due to China's current air quality evaluation system of sulfur dioxide, nitrogen dioxide, only inhalable particulate matter three kinds of index, already cannot reflect the Pearl River Delta Air quality deterioration of the essence. The Pearl River Delta atmospheric haze composition of fine particles in the" contribution" is more and more big, the current air quality evaluation system cannot describe the fine particles.
