The nitrate-nitrite-nitric oxide pathway elevates nitric oxide through the sequential reduction of dietary nitrate derived from plant-based foods. [13] Nitrate-rich vegetables, in particular leafy greens, such as spinach and arugula , and beetroot , have been shown to increase cardioprotective levels of nitric oxide with a corresponding ...
Most side effects are direct consequences of the vasodilation and the resultant low blood pressure. They include headache ("nitrate headache") resulting from the widening of blood vessels in the brain, reflex tachycardia (fast heart rate), flush, dizziness, nausea and vomiting. These effects usually subside after a few days if the treatment is ...
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]

Even though nitrogen is a necessary element for life, too much of it in water can have negative effects on aquatic ecosystems and endanger human health. Agricultural runoff, where fertilizers containing nitrogen compounds can seep into rivers, lakes, and groundwater, is one of the main sources of nitrogen in water.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
