foszátszennyezést

Foszátszennyezés refers to the excessive presence of phosphorus in bodies of water, primarily lakes and rivers. Phosphorus is a nutrient essential for the growth of aquatic plants and algae. However, when its concentration becomes too high due to human activities, it can lead to significant ecological imbalances.

The main sources of phosphorus pollution include agricultural runoff, which carries fertilizers and animal waste into waterways, and wastewater treatment plant discharges. Industrial processes and the erosion of natural phosphorus-containing rocks can also contribute.

The most visible consequence of foszátszennyezés is eutrophication. This process involves rapid algal blooms, often called "algal scum" or "green tides." As these algae multiply, they deplete dissolved oxygen in the water when they decompose, creating hypoxic or anoxic conditions. This oxygen depletion can lead to the death of fish and other aquatic organisms that cannot survive without sufficient oxygen.

Furthermore, some algal blooms can produce toxins that are harmful to both wildlife and humans, impacting drinking water supplies and recreational activities. Addressing foszátszennyezés involves implementing measures to reduce phosphorus input, such as improving agricultural practices, upgrading wastewater treatment facilities, and controlling erosion.
