研究警告：新车“香味”有毒！

展厅中的新车会散发出迷人的气味，甚至令人陶醉。这种“醉人”的味道不是白来的，而是来自多种化学产品的混合物，其中一些还具有很高的毒性。

The source of the bouquet⁶ so many buyers find appealing is in the various solvents⁷, adhesives⁸, plastics, rubbers and fabrics⁹ used in car construction. Many of these contain volatile¹⁰ organic compounds (VOCs), some of which can be deadly in sufficient quantities. Others are just bad for you.

这种让众多买家感到好闻的香味源于生产汽车所使用的各种溶剂、粘合剂、塑料、橡胶和纤维。其中许多成分还含有挥发性有机化合物，如果大剂量的接触这种化合物将会致命，其他一些化合物只是对身体不好。

香味

“It’s a chemical cocktail¹¹ made up of lots of toxins,” said Jeff Gearhart, Research Director of the Ecology Center in the US state of Michigan. The Ecology Center has been monitoring and testing chemical levels in car interiors for years, and has noted¹² some improvement. But Gearhart says there is still work to be done.

美国密歇根州生态中心研究室主任杰夫?吉尔哈特说：“这是由许多毒物混合而成的化学鸡尾酒”。生态中心近年来一直在监测并检验汽车内部的化学物质水平，而且已经看到了一些进展，但是吉尔哈特称，还有不少工作要做。

“There are over 200 chemical compounds found in vehicles,” he said. “Since these chemicals are not regulated, consumers have no way of knowing the dangers they face.”

他说：“汽车内部有两百多种化学混合物。因为这些化学物质不受监管，所以消费者无从知晓自己所面临的危险”。

Just reading a list of the substances is scary enough, and makes your car’s interior sound like a hazmat hall of fame. Benzene, toluene, formaldehyde, and heavy metals are all part of the mix. And the danger of exposure is scarier still. Immediate¹³ symptoms can range from a sore throat to headaches, dizziness, allergic¹⁴ reactions and nausea¹⁵, depending on the sensitivity of an individual.

仅仅是读一下这些化学物质的名单就已经够吓人的了，你的汽车听起来就像是危险物的名品堂。苯、甲苯、甲醛和重金属都名列其中。而且，接触这些化学物质带来的危险更加可怕，可能会即刻产生咽喉肿痛、头痛、眩晕、过敏反应、恶心等症状，症状根据每个人的敏感程度而不尽相同。

According to the US Environmental Protection Agency, continued exposure to some of these can lead to hormonal¹⁶ disruption, reproductive impacts and damage to the liver, kidneys and central nervous system — or even cancer. It’s that long-term exposure that experts find most worrisome.

据美国环保署称，持续与其中一些化学物质接触可能导致荷尔蒙紊乱、生殖功能下降，对肝、肾、中枢神经系统造成破坏——甚至会引发癌症。专家们认为最值得担忧的就是这种长期接触。

“People spend over an hour a day in their vehicles on average,” said Gearhart. “Whether it’s adults, children, or pets, we’re concerned about prolonged exposure to toxic chemicals inside the vehicle.”

吉尔哈特说：“人们平均每天要在汽车内待一个小时以上。我们十分关注长期在汽车内接触有毒化学物质带来的危害，无论里面坐的是大人、小孩、还是宠物”。

The danger is greatest when the car is new, and that new car smell is most noticeable. This is when components¹⁷ are still unstable¹⁸ and prone¹⁹ to what is called off-gassing — the release of chemical vapours, which leads to the odour. Heat from a vehicle left in the sun can make matters worse, and speed up the chemical reaction. The danger is reduced over time, and experts say the worst is usually over within about six months.

新车的气味最明显，对健康的危害也最大。因为新车中的化学成分还不稳定，容易进行所谓的“逸散”——即化学气体挥发，这样就产生了气味。太阳下暴晒的汽车会使情况更糟，因为高温会加速化学反应。汽车使用时间越长，危害越小，专家称最严重的时候就是购车后的头六个月。

Experts advise the best thing that buyers can do to limit exposure is to keep car interiors well ventilated, especially during the first six months of ownership. Park in the shade with the windows open when it’s safe to do so, or at least try to air it out before getting inside — especially on hot days.

专家建议购买者最好保持车内通风良好以减少同化学物质的接触，尤其是在刚买车的头六个月。把车停在阴凉处，如果开窗安全的话，就把车窗打开，或者至少在上车前先通风换气，特别是在天热的时候。
