英文摘要Oceanic and anthropogenic processes, such as sea-salt emissions and combustion activities, release substantial amount of reactive chlorine into the troposphere, affecting air quality, ozone depletion, and climate change. However, distinguishing between these sources for reactive chlorine remains challenging. Here, we establish isotopic constraints on the origin of tropospheric reactive chlorine using chemical ionization mass spectrometry to analyze nitryl chloride (ClNO2). Field observations from four regions in China reveal a much broader isotopic value (delta 37Cl) range for ClNO2 (-21 to +39 parts per thousand) than previously documented for Earth's chlorine reservoirs. Notably, significant delta 37Cl differences for ClNO2 from sea-salt emissions (-9 +/- 4 parts per thousand) and anthropogenic combustion sources (+20 +/- 7 parts per thousand) were identified. These distinct isotopic signatures, combined with field data, highlight the important role of oceanic chlorine in air pollution, with its chemical cycling affecting not only coastal regions but also extending into inland areas. This research advances our understanding of chlorine's behavior and cycling in the troposphere.
