研究表明,罗马采矿的铅污染可能使欧洲智商降低了2.5至3个百分点。 Study suggests lead pollution from Roman mining may have lowered Europeans' IQ by 2.5 to 3 points.

《国家科学院议事录》中的一项新研究表明,罗马帝国时期采矿和冶炼活动造成的铅污染可能已导致欧洲人智商大幅下降。 A new study in the Proceedings of the National Academy of Sciences suggests that lead pollution from mining and smelting activities during the Roman Empire may have caused a significant decline in IQ among Europeans. 研究人员分析了冰芯记录,估计铅接触可能会将平均智商水平减少2.5至3点。 Researchers analyzed ice core records and estimated that lead exposure could have reduced average IQ levels by 2.5 to 3 points. 这项研究突出说明了工业污染对健康的长期影响,甚至可追溯到2000年以上。 The study highlights the long-term health impacts of industrial pollution, even dating back over 2,000 years.
