Economic loss of zinc materials from air pollution and corrosion - A case study of kunming city

In this paper, the method for estimating the economic loss of atmospheric corrosion of materials is introduced briefly. And the Kunming city is selected as a representative area. The corrosion loss of zinc materials was estimated quantitatively by using the response function of corrosion damage and the calculation formula of service life. The results showed that the annual direct economic loss caused by atmospheric pollution corrosion damage to zinc materials was about 56 million yuan, which is about 0.16% of GDP of the same period. Among them, the contribution rate of dry settlement to total economic loss is between 67% and 95%, and the mean value is 91%. Copyright © 2018, AIDIC Servizi S.r.l.
