Foszfortúlmennyiség

Foszfortúlmennyiség refers to an excessive level of phosphorus in a given environment, most commonly observed in aquatic ecosystems. Phosphorus is a vital nutrient for the growth of plants and algae, but when its concentration becomes too high, it can lead to rapid and uncontrolled proliferation of these organisms. This phenomenon is known as eutrophication.

The primary sources of excess phosphorus in water bodies are often anthropogenic. Agricultural runoff, carrying fertilizers containing phosphorus, is a significant contributor. Wastewater treatment plants, if not adequately equipped to remove phosphorus, can also discharge large amounts into rivers and lakes. Industrial discharges and the use of phosphorus-based detergents have also played a role in the past, although regulations have reduced their impact in many regions.

The consequences of foszfortúlmennyiség can be severe. The excessive algal growth, often referred to as algal blooms, can block sunlight from reaching submerged aquatic vegetation, leading to their death. When these blooms die, their decomposition consumes large amounts of dissolved oxygen in the water. This deoxygenation can create hypoxic or anoxic conditions, making the water unsuitable for fish and other aquatic life, leading to fish kills. Some algal blooms can also produce toxins harmful to both aquatic organisms and humans. Managing phosphorus inputs is crucial for maintaining the ecological health of aquatic ecosystems.
