Reactive nitrogen-driven atmospheric multiphase buffering induces unintended concomitant pollution.

ABSTRACT: Atmospheric multiphase buffering capacity is a crucial physicochemical property of aerosol that significantly influences the Earth's radiative budget, climate, air quality, and public health. However, its implications for air pollution remain largely unexplored. Here, we present four years of continuous observation and laboratory experiments as evidence that reactive nitrogen (Nr)-driven atmospheric multiphase buffering can induce unintended Concomitant Pollution. Specifically, gaseous pollutants undergo phase partitioning into aerosol aqueous phases during the process of pH change under buffering constraints, subsequently transforming into concomitant particulate pollution. Furthermore, from a global perspective, we reveal that NH₄⁺/NH₃-induced Concomitant
