Browsing: Acidification
Acidification refers to the process of becoming acidic or increasing in acidity. In environmental contexts, it is most commonly associated with two phenomena: ocean acidification and soil acidification. Ocean acidification occurs when seawater absorbs carbon dioxide from the atmosphere, leading to chemical reactions that reduce the water’s pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals. This affects marine organisms like corals, shellfish, and plankton, which rely on carbonate ions to build their shells and skeletons. Soil acidification, on the other hand, is often caused by the use of agricultural fertilizers and acid rain. It results in a decrease in soil pH, negatively impacting plant growth, soil microbial activity, and soil chemistry, potentially leading to reduced agricultural productivity. Both types of acidification pose significant challenges for ecosystems and human activities dependent on them.
