为什么人的智力受污染的影响？
人的智力受污染影响，主要是因为污染物会引发神经炎症、氧化应激，以及重金属对神经系统的毒性作用。
1、神经炎症与氧化应激：空气污染中的颗粒物（如PM2.5）会引发神经炎症和氧化应激，损害大脑结构和认知功能，降低记忆力、语言能力和非语言智力。
2、重金属毒性：环境中的重金属（如铅、汞、砷）通过食物链或直接接触进入人体，干扰神经递质合成，损害大脑发育，导致智力下降，尤其是儿童更为敏感。
3、长期暴露的累积效应：污染物长期作用于人体，可能通过慢性炎症和毒性累积，逐步损害认知能力，相当于“失去受教育经历”。
总结：人的智力受污染影响，主要是因为污染物会引发神经炎症、氧化应激，以及重金属对神经系统的毒性作用。
