More water-soluble brown carbon after the residential “coal-to-gas” conversion measure in urban Beijing

W. Yuan, R. Huang, et al.

This study by Wei Yuan and colleagues explores the effects of Beijing's 'coal-to-gas' residential conversion on brown carbon (BrC). The findings reveal a noteworthy increase in water-soluble BrC compounds and a decrease in water-insoluble forms, suggesting a trend toward more reactive, highly oxygenated BrC. This research opens the door for deeper inquiries into residential coal combustion and BrC formation.
