Abstract：Soluble iron in atmospheric aerosols substantially influences marine primary productivity,climate change,secondary atmospheric pollution,and human health.Identifying sources and developing high-accuracy emission inventories of soluble iron are fundamental for refining biogeochemical models to simulate iron deposition fluxes and marine productivity,improving atmospheric chemistry transport models for secondary aerosol simulations and quantifying the sources and contributions of soluble iron affecting human health.This study systematically reviews the source apportionment of iron and soluble iron in atmospheric aerosols,the key factors and underlying mechanisms governing iron solubility,and recent methodological advances in sampling and characterization of combustion-derived iron-containing aerosols.With particular focus on emission inventory development for combustion-related soluble iron,we critically examine current methodologies and identify persistent challenges.It is expected the summarization here provides a basic dataset and theoretical frameworks for accurate assessment of iron's climatic,environmental and health impacts.
