      "excerpt": "Here we examined the causal impact of air pollution on the academic publications of individual scholars in China. Using an instrumental variable design and combining air quality data with a bibliographic dataset of publications, we found that an increase of 1 μg m−3 in the annual concentration of PM2.5 (particles smaller than 2.5 μm in diameter) causes a decline of 0.23% (P < 0.01; 95% confidence interval, −0.0028 to −0.0017) in publications. The mean PM2.5 concentration was 45.91 over the study period. A 1% increase in PM2.5 concentration results in a reduction of approximately 1,053 publications nationwide. This effect was more pronounced during years of heavy pollution, especially among highly productive and younger scholars.",
