一项研究发现,孕产妇在怀孕期间遭受空气污染与新生儿大脑发育缓慢有关。 Maternal exposure to air pollution during pregnancy is linked to slower brain development in newborns, a study finds.

一项新的研究将孕妇在怀孕期间受到空气污染,特别是细微颗粒物质(PM2.5)的污染与新生儿大脑发育迟缓联系起来,具体地说,在婴儿出生的第一个月中,透析率下降。 A new study links maternal exposure to air pollution, particularly fine particulate matter (PM2.5), during pregnancy to slower brain maturation in newborns, specifically reduced myelination in the first month of life. 研究人员分析了巴塞罗那132名婴儿的MRI扫描结果,发现高PM2.5水平——特别是在第二和第三个季度——与延缓神经纤维涂层有关,这是大脑功能的关键过程。 Analyzing MRI scans of 132 infants in Barcelona, researchers found that higher PM2.5 levels—especially in the second and third trimesters—were associated with delayed nerve fiber coating, a key process for brain function. 该研究报告发表在《环境国际》上,它没有证明因果关系,而是补充了空气质量影响胎儿大脑发育的证据。 The study, published in Environment International, does not prove causation but adds to evidence that air quality affects fetal brain development. 专家们强调需要加强空气质量标准和进一步的研究,特别是在污染程度较高的城市地区。 Experts stress the need for stronger air quality standards and further research, particularly in urban areas where pollution is higher.
