机动车的快速增长和持续的灰霾天气,使珠三角地区逐步受到光化学污染的威胁。光化学污染是一次污染物VOCs和NO2在阳光下经光化学反应生成,臭氧是光化学污染现象的代表性成分。由于城市之间存在着大气污染的相互影响和输送问题,臭氧污染物存在相邻城市同期达到峰值的现象。环境保护部副部长张力军表示,根据北京奥运会期间的空气质量保障工作总结的经验,我国将从“十二五”开始,将用区域联防联控治理大气污染,来代替单个城市的单独治理,可见大气污染的区域性特征已逐步成为人们共识。
The rapid growth of motor vehicles and the continuous haze weather have gradually exposed the Pearl River Delta region to the threat of photochemical pollution. Photochemical pollution is a pollutant VOCs and NO2 in the sunlight generated by photochemical reactions, ozone is a photochemical pollution phenomenon representative components. Ozone pollutants peaked in neighboring cities over the same period as a result of the interplay and transfer of air pollution between cities. Zhang Lijun, vice minister of the Ministry of Environmental Protection, said that according to the experience summed up in the air quality assurance work during the Beijing Olympic Games, China will start with the “Twelfth Five-year Plan” and will use regional joint prevention and control to control atmospheric pollution instead of individual cities Governance, visible regional characteristics of air pollution has gradually become the consensus.
