　　Besides inciting the occasional bout of road rage, traffic jams may have other harmful effects on thebrain, say scientists.

　　A growing body of research on traffic pollution and the brain has shown there's more to it than we think. Association studies arefinding links between higher exposure to pollution and certain cognitive problems. Researchers such as Columbia University's Frederica Perera are discovering that pollution's imprint can begin before birth, as newborns with higher exposure show permanent genetic differences from other babies. This finding, coupled with findings that kids exposed to higher rates of pollution perform worse in intelligence and emotional tests, raises questions bsgut how pregnant women and children can reduce their exposure.

　　In one experiment, Perera asked pregnant women in Poland to carry around air monitors in order to collect dataabout the quality of air the future mothers were breathing.She tracked the children after birth and found those with higherexposures lagged behind developmentally.

　　Other measurements show that older women exposed to higher levels of particulate matter had a higher chance ofdeveloping neurodegenerative problems such as Alzheimer's disease. In the United States, where industry emits moreparticulate matter than vehicles at times, it's hard to tease out other sources of emissions. For the most part, though, there's arelationship between local traffic and exposure, which has become apparent by studying mice, too.

　　It's been established that being exposed to particulate matter influences a person's chance of developing respiratoryand heart problems, but pining down trends for the brain has been difficult, mostly because researchers have to measureeffects indirectly.

　　The idea that pollution has negative health effects might seem obvious to some, but the research community is onlybeginning to explore the range of potential effects on development and cognition in the long term. So far, changesthat ease traffic一whether it be better timed lights during rush hour or placing E-ZPass systems near tollways一have beeneffective in curbing pollution levels.

　　科学家称，交通阻塞除了偶尔会引发交通暴怒行为之外，还可能对大脑产生其他危害。

　　越来越多针对交通污染和大脑的研究表明，两者之间的关联比我们以为的更强。关联研究发现，经常接触污染物会导致某些认知疾病。哥伦比亚大学的弗雷德里卡·佩雷拉等研究人员发现，与其他孩子相比，经常接触污染物的新生儿表现出的基因差异，这说明污染物的影响早在婴儿出生之前就开始了。另外，接触重度污染的孩子在智商和情商测试中都表现较差。综合考虑这两点，如何减少孕妇和儿童与污染物接触的问题就浮出水面。

　　在一项试验中，佩雷拉让几位波兰孕妇随身携带大气污染监测器，从而收集这些准妈妈们呼吸的空气质量的数据。孩子出生之后，她继续跟踪，发现那些重度污染地区的孩子们发育较为迟缓。

　　其他测试表明，年长女性接触悬浮微粒较多的环境时患阿兹海默症等神经变性疾病的几率更高。在美国，有时工业排放的悬浮微粒比汽车还多，很难确定到底是哪种污染源导致了认知障碍。但是，总的来说，当地交通和污染接触之间存在一定关联，这在对小白鼠的研究中也已变得相当明显。
目前已经确知接触某些污染物会增加患呼吸道疾病和心脏疾病的几率。但很难确定其与大脑疾病的关系，主要是因为研究人员只能间接测量其影响。

　　对某些人而言，污染有害健康是显而易见的事。但研究人员对污染物引起的对发育和认知的长期潜在危害的研究才刚刚起步。到目前为止，无论是交通拥挤时段更好的红绿灯时间设置;还是在收费公路上设置电子收费系统，这些减缓交通的改变都有效控制了污染登记。
