nutriëntenbelasting

Nutriëntenbelasting refers to the excessive input of nutrients, primarily nitrogen and phosphorus, into an aquatic ecosystem. This influx of nutrients can originate from various sources, including agricultural runoff, wastewater treatment plant discharges, and atmospheric deposition. When nutrient levels become too high, they can disrupt the natural balance of the ecosystem.

One of the most significant consequences of nutriëntenbelasting is eutrophication. This process is characterized by an overgrowth of algae and aquatic plants, often referred to as algal blooms. These blooms can deplete dissolved oxygen in the water, leading to hypoxic conditions that are harmful or fatal to fish and other aquatic organisms. The decomposition of dead algal matter further consumes oxygen and can release toxic substances.

Nutriëntenbelasting can also impact biodiversity by favoring certain species that thrive in nutrient-rich conditions while negatively affecting others. This can lead to a less diverse and less resilient ecosystem. The aesthetic quality of water bodies can also be diminished, with murky water and unpleasant odors becoming common. Addressing nutriëntenbelasting often involves implementing measures to reduce nutrient runoff from agricultural lands, improving wastewater treatment processes, and controlling emissions that contribute to atmospheric nutrient deposition.
