Increased contribution of biomass burning to haze events in | ResearchBunny

Abstract

This study investigates the sources and geographical origins of black carbon (BC) aerosols in Shanghai, China, after the implementation of clean air actions from 2013-2017. By combining dual-isotope-constrained observations and chemical-transport modeling, the researchers found that while fossil sources dominate BC in cleaner summer months, biomass burning significantly contributes to wintertime BC pollution, primarily due to residential emissions. This highlights the need for substantial reductions in regional residential emissions to address haze and mitigate climate impact.
