与青少年大脑变化相关的空气污染,即使在安全水平上也是如此。 Air pollution linked to brain changes in teens, even at safe levels.

OHSU研究人员的一项研究发现,接触普通空气污染物,如微粒物质、二氧化氮和臭氧,可能损害青少年的大脑发育。 Exposure to common air pollutants like particulate matter, nitrogen dioxide, and ozone may harm brain development in adolescents, a study by OHSU researchers finds. 通过分析近11 000名儿童的数据,这项研究将这些污染物的早期暴露与对情绪、记忆力和执行功能至关重要的脑部地区的非典型皮层薄化联系起来。 Analyzing data from nearly 11,000 children, the study links early exposure to these pollutants with atypical cortical thinning in brain regions critical for mood, memory, and executive function. 尽管没有立即出现症状,但变化可能扰乱长期的认知和情感发展,可能影响注意力、学习和行为。 Though no immediate symptoms appear, the changes may disrupt long-term cognitive and emotional development, potentially affecting attention, learning, and behavior. 即使在当前安全标准范围内的污染水平上也可以看到这种影响,使人们对空气质量对青年精神和神经健康的影响产生担忧。 The effects were seen even at pollution levels within current safety standards, raising concerns about air quality's impact on youth mental and neurological health.
