  • What are the Effects of Corrosion?

    Aug 22, 20179 minutes to read. Some of the effects of corrosion include a significant deterioration of natural and historic monuments. Air pollution causes corrosion, and it's becoming worse worldwide. One of the consequences of air pollution that is seldom talked about is the effect of corrosion on man-made materials throughout the world.
