摘要
近年来,我国频繁出现持续雾霾天气,导致民众对其关注度居高不下。PM2.5又称细颗粒物,作为雾霾天气的主要污染物不仅能较长时间悬浮于空气中,且成分构成复杂,颗粒粒径小、活性强、悬浮时间长、运输距离远,从而成为多环芳烃、重金属、致病微生物等毒物的载体,吸入人体后严重危害人体健康。鉴于中国汽车保有量激增,广大消费者日益重视汽车内部空气中PM2.5浓度的问题。本文通过检测处于四种工况下车辆内外空气中的PM2.5浓度,对目前部分市售热门车型的密闭性、车内PM2.5浓度及车内空气净化系统的净化能力进行了系统评价。
Haze weather has occurred frequently, now people in China are paying high attention to it. As a main pollutant of haze weather, PM2.5 is not only suspended in the air for a long time, but also has the characteristics of complex composition, small particle size, strong activity, long levitation time, long transportation distance. As a carrier of polycyclic aromatic hydrocarbons, heavy metals, pathogenic microorganisms and other poisons, inhalation of the human body seriously endanger the health of the body. In view of the surge in car ownership in China, the majority of consumers pay more and more attention to the issue of PM2.5 concentrations in the air inside vehicles. In this paper, the concentration of PM2.5 in the air inside and outside of the vehicle has been tested to evaluate the vehicle＇s airtightness, concentration of the PM2.5 and the purifying ability of the air purifying system in the vehicle in some popular models from market by the four operating conditions.
