Anthropogenic-Biogenic Interaction Drives Chloride Depletion in Coastal Atmosphere

, etc.) that have been previously observed in ambient particles were identified, indicating that reactive chlorine produced from chloride depletion serves as a critical oxidant for the formation of organic chlorinated compounds. This study advances the understanding of chloride depletion influenced by anthropogenic-biogenic interactions in a coastal atmosphere and provides evidence for the formation of organic chlorinated compounds in coastal ambient particles.
