Once the pH increases reaches the threshold of 3.5, the acid rain can no longer be beneficial and begins to have negative affects. [87] Acid rain can negatively impact photosynthesis in plant leaves, when leaves are exposed to a lower pH, photosynthesis is impacted due to the decline in chlorophyll. [88]
Impacts of acidic water and Soil acidification on plants could be minor or in most cases major. In minor cases which do not result in fatality of plant life include; less-sensitive plants to acidic conditions and or less potent acid rain. Also in minor cases the plant will eventually die due to the acidic water lowering the plants natural pH.
Acid rain has numerous ecological impacts on streams, lakes, wetlands and other aquatic environments. It damages forests, robs the soil of its essential nutrients, and releases aluminium in the soil, which creates difficulties in the absorption of water for local plant life.
The main source of sulfur and nitrogen compounds that result in acid rain are anthropogenic, but nitrogen oxides can also be produced naturally by lightning strikes and sulphur dioxide is produced by volcanic eruptions. [66] Acid rain can have harmful effects on plants, aquatic ecosystems and infrastructure. [67] [68]
Governmental action to combat the effects of acid rain. The discovery of these negative effects spurred the rush to reduce atmospheric sulfate pollution, typically through flue-gas desulfurization installations at power plants, such as wet scrubbers or fluidized bed combustion.
Acid rain: The burning of fossil fuels releases oxides of sulfur and nitrogen into the atmosphere. These react with water in the atmosphere to form sulfuric and nitric acid in rain. Oxidative weathering: Oxidation of some primary minerals, especially sulfides and those containing Fe 2+, generate acidity.
Trees killed by acid rain, an unwanted side effect of burning petroleum. The combustion process of petroleum, coal and wood is responsible for increased occurrence of acid rain. Combustion causes an increased amount of nitrous oxide, along with sulfur dioxide from the sulfur in the oil. These by-products combine with water in the atmosphere to ...
Oil sand pollution is not only set to increase VOCs, but also, acid rain. [5] Acid rain is rain that has been contaminated by airborne chemicals, making it acidic. [6] Two major causes of acid rain are sulphur dioxide and nitrogen oxide. [7] Acid rain can cause damage to soil, water, wildlife, plants and buildings. Additionally, the airborne ...
