研究发现香味产品也会污染空气

The chemicals found in items you use every day - like your shampoo, perfume and cleaning products - now have as much of an impact on air pollution as vehicle emissions, according to a new study by the National Oceanic and Atmospheric Administration (NOAA).

美国国家海洋和大气管理局进行的最新研究发现，在洗发水、香水和清洁用品等人们每天使用的物品中发现的化学物质如今对空气污染的影响与汽车排放的影响一样大。

Researchers used 15 times more petroleum as fuel than as ingredients in consumer and industrial products, they said, yet the amount of chemical vapors released into the atmosphere through scented products is roughly the same as through fuel emissions.

研究人员表示，在消费者和工业产品中，他们使用的石油燃料是原料的15倍，然而，通过香味产品释放到大气中的化学蒸汽量与燃料排放量大致相同。

Those vapors are volatile organic compounds (VOCs). They react with sunlight to form ozone pollution, and the researchers found they also react with various chemicals in the atmosphere to create fine particulates in the air.

这些蒸汽是挥发性有机化合物。它们与阳光发生反应形成臭氧污染，而且研究人员发现，这些蒸汽还会与大气中的各种化学物质发生反应，从而产生空气中的细微颗粒。

"As the transportation sector gets cleaner, these other sources of volatile organic compounds become more and more important," said a NOAA scientist. "A lot of stuff we use in our everyday lives can impact air pollution."
