今年,北京的天气反复无常,从年初的雾霾到最近的乍暖还寒。当人们还在每天关注PM2,5的时候,孰不知比PM2,5更毒的空气已经被我们所忽视,那就是车内污染。车内空气污染问题,被世界卫生组织明确为人类健康十大威胁之一,被美国列入人类健康的五大危害。 This year, the weather in Beijing is capricious, from the haze at the beginning of the year to the recent warming. When people are still paying close attention to PM2,5 every day, everybody knows that the air that is more poisonous than PM2,5 has been neglected by us, that is the pollution inside the car. Air pollution in the car, the World Health Organization has been identified as one of the top ten threats to human health, the United States included in the five major human health hazards.
