公交车、出租车、轻轨和越来越多的私家车作为最便捷的交通工具,为人们的出行提供了方便,但汽车车厢的空气污染常常不被人们所重视。车厢内的空气污染首先来自汽车本身的一氧化碳、汽油挥发物HC等;其次是来自人体的CO2、体臭;第三是来自空气中的灰尘。另外,专家从车厢内的拉手、靠背、扶手、座椅等部位,均检出有各类病毒及细菌。这些有害物质会导致乘车人头晕、恶心、打喷嚏,甚至引起更严重的疾病[1]。我国在1996年颁布过车厢内细菌总数的卫生标准,但随着车厢的密封性加强和空调的使用率加大,车厢内的空气质量也随之下降,显然这个卫生标准已无法满足现代高档车的卫生检验标准。所以,汽车厂家和有关职能部门也正在修订新的车厢内空气质量标准,被誉为车内“杀手”的微生物也将因此被控制。
Buses, taxis, light rail and more and more private cars as the most convenient means of transport for the convenience of people’s travel, but the air pollution of the car compartment is often not taken seriously. Air pollution inside the car comes first from the car’s own carbon monoxide, gasoline volatile HC, etc .; followed by the body’s CO2, body odor; the third is from the dust in the air. In addition, experts from the compartment handle, backrest, handrails, seats and other parts, were detected with various types of viruses and bacteria. These harmful substances can cause motorists to feel dizzy, nauseated, sneezing and even cause more serious illnesses [1]. China issued a total number of bacteria in the car in 1996, the health standards, but with the enhanced sealing of the car and the increased use of air conditioners, air quality within the car also will decline, it is clear that the health standards have been unable to meet the modern high-end car Health inspection standards. Therefore, the car manufacturers and relevant functional departments are also amending the new air quality standards inside the car, known as the car “killer ” microorganisms will also be controlled.
