摘要
大气颗粒物污染已经成为对中国环境质量影响的一大关键因素,调查显示,全世界约有11亿多的人口正遭受着大气污染的侵害。城市化进程的推进,使人群过敏和花粉污染现象日趋严重,花粉颗粒能够粘附大气颗粒物并与颗粒物产生交互作用,从而导致花粉致敏性加强。大气颗粒物复杂的组分加之特殊的粒径尺寸,人群很容易经呼吸道吸入这些大气细/超细颗粒物,对呼吸系统造成严重的氧化损伤,进而影响健康。鉴于飞散花粉和颗粒物危害极大,但其具体协同作用机制尚不明确,该文就国内外目前的研究现状做一总结,为进一步开展相关实验提供参考。
Atmospheric particulate matter pollution has become a key factor to environmental quality. It shows that more than 1.1 billion people is suffering from the impact of air pollution around the world. The crowd allergy and pollen pollution is becoming more and more serious with the advancing of urbanization. Pollen particles can adhere to the atmospheric particulate matter together and interact with the particles in multiple ways, leading to pollen allergy enhanced. Atmospheric particulate component is complex coupled with special size, people are easily taking these atmospheric fine/ultrafine particles by inhalation, causing serious oxidative damage to the respiratory system, and threaten people＇s health. In view of the great harm of airborne pollen and particulate matter, moreover the specific coordination mechanism is still not clear, this paper summarizes the current research status at home and abroad, to provide reference for the further development of the related experiments.
