Nutrient content (water) in the context of environmental and water science topics refers to the concentration and speciation of dissolved and particulate nutrients—primarily nitrogen (e.g., nitrate, nitrite, ammonium, dissolved organic nitrogen) and phosphorus (e.g., orthophosphate, dissolved and particulate organic phosphorus), as well as ancillary elements such as silica—within freshwater, marine, or wastewater systems. It is quantitatively assessed using chemical and sometimes bioassay methods to characterize trophic status, evaluate eutrophication risk, model biogeochemical cycles, and inform regulatory standards for water quality, ecological health, and resource management.
Low-intensity green lighting in refrigerated storage can slow spoilage in leafy greens, helping maintain their appearance and nutritional value, according to a new study from McGill University. The research, published in ...
