新奇事件簿 警惕你的家居日用（在线收听）

Scientists say we are unaware of a massive cause of pollution that is right under our very noses. Everyday household items such as toothpaste, shaving foam, deodorant, perfume and furniture polish contain volatile compounds that help to cause pollution. Dr Brian McDonald, an air-pollution researcher at the US National Oceanic and Atmospheric Administration, conducted research into how our homes create pollution. His team was surprised to find that household items now contribute as heavily to particular types of air pollution as cars, trucks and other vehicles. Dr McDonald said that as "the transportation sector gets cleaner, these other sources...become more and more important".

科学家们表示人类还未意识到存在于我们眼皮子底下的大量污染源。牙膏、剃须泡沫、除臭剂、香水以及家具打光料等常家居用品含有造成污染的挥发性化合物。布莱恩·麦克唐纳博士是美国国家海洋与大气管理局里的一名大气污染研究人员，他对家居如何制造污染进行研究。他的团队惊奇的发现家居用品如今也和汽车、卡车以及其他车辆一样是空气污染的特殊类型。布莱恩·麦克唐纳博士说道“运输行业变得更加洁净，这些其他来源也变得越来越重要。”

The researchers focused on volatile organic compounds (VOCs) in a whole range of household items. VOCs react with sunlight to form ozone pollution. This escapes into the environment and gets trapped in our house or apartment, causing pollution in our homes. The scientists said VOCs interact with other chemicals to form tiny particles in the air. These particles can lead to lung damage. Dr McDonald said governments should regulate household products more tightly to reduce their negative impact on our health. He issued a stark warning, saying: "The things I use in the morning to get ready for work are comparable to emissions that come out of the tailpipe of my car."

研究人员主要专注于家居用品全部范围内的挥发性有机物（VOCs）。VOCs和臭氧污染中的阳光进行反应。逃入环境之中、困在我们的房子或公寓中并造成污染。科学家们表示VOCs与其他化学物质相互作用以形成空气中的微粒。这些微粒会造成肺损伤。麦克唐纳博士称政府应该对日用品加紧管控以减少它们对人类健康的负面影响。他发出严厉警告称：“早晨上班前我们所使用的物品和从我的汽车排气管里所释放出来的排放物相当。”
