Acid rain. Conifer forest showing trees damaged by acid rain. Acid rain occurs when industrial pollutants such as sulphur and nitrogen oxides are released into the atmosphere. The gases dissolve in atmospheric water, forming acidic solutions. When these fall as rain they can damage plants, masonry and freshwater life. Continual monitoring and control of air pollution is required to keep the problem under control.
