What they found
In 2020, China's national annual mean PM2.5 concentration was 32.6 µg/m³, significantly above WHO safe levels. Achieving stricter air quality targets could avert 0.41 million premature deaths.
What they studied
Researchers quantified the projected health and economic benefits of reducing PM2.5 concentrations in China under the Healthy China 2030 plan and various WHO targets. They used 2020 ground-level PM2.5 data as a baseline for 337 cities.
Takeaways
The abstract focuses on the study's findings regarding policy impacts; it does not give personal how-to steps for individuals.
About this paper
This was a modeling study that projected cause-specific mortality and morbidity outcomes for 337 prefecture-level cities in China. The analysis used 2020 PM2.5 data as a baseline and accounted for nearly 70% of China's total population. The study highlights the need for more stringent air quality control.
