产前野火接触烟雾,特别是在第三季度,与儿童的自闭症风险较高相关联。 Prenatal wildfire smoke exposure, especially in third trimester, linked to higher autism risk in children.

一项新的研究将产前接触野火烟(特别是在第三季度)与儿童患自闭症的风险较高联系起来,发现1-5、6-10天和10天以上吸烟的概率分别增加10%至23%。 A new study ties prenatal exposure to wildfire smoke—especially in the third trimester—to a higher autism risk in children, finding a 10% to 23% increased likelihood with 1–5, 6–10, and over 10 smoky days, respectively. 2006年至2014年对20多万名南加州出生婴儿进行了分析,研究人员将这一风险与烟雾中的PM 2.5粒子联系起来,这可能会进入血液流,影响大脑发育。 Analyzing over 200,000 Southern California births from 2006 to 2014, researchers linked the risk to PM 2.5 particles in smoke, which can enter the bloodstream and affect brain development. 虽然没有证明因果关系,但调查结果进一步证明,空气污染可能助长自闭症,这影响到31名美国学龄儿童中的1名。 While not proving causation, the findings add to evidence that air pollution may contribute to autism, which affects 1 in 31 U.S. school-aged children. 专家们强调有必要加强空气质量条例和进一步研究。 Experts stress the need for stronger air quality regulations and further research.
