Agricultural runoff, livestock operations, aquaculture, food processing facilities, pulp and paper mills, sewage treatment plants, and fossil fuel combustion are some typical examples of industries that cause nutrient pollution.
Agricultural runoff, livestock operations, aquaculture, industry (e.g., food processing facilities and pulp and paper mills), sewage treatment plants, and fossil fuel combustion are the major sources of nutrient pollution [ 1].
