研究员表示:空气污染或增加自闭风险

"The study showed a small increase in autism for infants exposed before birth to one of the pollutants: nitric oxide. While it's a small increase, if large populations are exposed, it could still affect many children," Lynn Singer, PhD, professor of population and quantitative health sciences, pediatrics, psychiatry, and psychology at the School of Medicine at Case Western Reserve University in Ohio, told Healthline.

"研究发现：婴儿出生前暴露于一氧化氮这一污染物使得他们患自闭症的可能性略有增加。虽然是小幅度增长，但如果大量人口处于污染环境中，受影响的儿童将会增多，"俄亥俄州凯斯西储大学医学院人口和定量健康科学，儿科，精神病学和心理学教授林·辛格（Lynn Singer）博士对美国健康在线网说道。

"It confirms some previous research and suggests that air pollution should be studied further regarding how it relates to autism," she added. However, neither study proved that air pollution is causing ASD. The researchers have only found that children in an area with air pollution are at a greater risk.

"这证实了先前的某些研究，表明人们应进一步就空气污染与自闭症之间的关系开展研究，"她补充道。然而，尚未有研究表明空气污染直接导致自闭症。研究员只是发现：处于空气污染地区的儿童患自闭症的可能性更高。

No proof yet on what causes ASD. In recent years there have been a lot of studies claiming to have found a link between one thing or another and an increased risk of ASD. Acetaminophen, sold under the brand name Tylenol, is a good example. Research published in the American Journal of Epidemiology concluded there's evidence that using acetaminophen for 28 days or more during pregnancy was linked with a 20 percent increase.
