Oct 28, chapter 10: human alteration of the atmosphere, p. 1-17 covered: Industrial and photochemical song: the industrial revolution is the underlying cause for the increase of pollutants. Nov 2, ch10 human alteration of the atmosphere: p. 17-35 covered. This is about 1000 times more acidic than natural. Effect of acid deposition: acid deposition influences the environment in several different ways. In aquatic system, acid deposition can degrade these ecosystems by lowering their ph. In aquatic systems on natural or acidic bedrock are normally very sensitive to acid deposition (lack basic compounds: originally, it was believed that the fish die-offs in lakes were occurring because of the increasing acidity of the water. In the 1970s, scientists discovered that acidified lakes also contained high concentrations of toxic heavy metals like mercury, aluminum, and cadmium: many acidified aquatic systems experience a phenomenon known as.
