In this paper, the factors which would influence the atmospheric corro- sion of metals such as size and distribution, chemistry, transmission and deposition of aerosols were introduced. The physical, chemical and electrochemical interaction between aerosol and metal surface, and constituent of pollutants in aerosol were reviewed emphatically in order to summarize the influence of aerosols on metal corrosio
