Fertilizers, when washed into rivers through runoff, can lead to nutrient pollution, primarily from nitrogen and phosphorus. This excess nutrient load stimulates algal blooms, which can deplete oxygen levels in the water, creating dead zones that harm aquatic life. Additionally, harmful algal blooms can produce toxins that affect water quality and pose risks to human health. Overall, the impact of fertilizers on rivers disrupts ecosystems and diminishes biodiversity.
