nitrates

A family of chemically stable forms of inorganic nitrogen, which are formed as part of the natural breakdown of organic matter. Nitrates are ingested in vegetables and absorbed from the gastrointestinal tract; an estimated 25% of absorbed nitrates are released into the saliva, 20% of which are converted into nitrites. Nitrates are manufactured for use as fertilisers and explosives and tend to accumulate in the environment, as the uptake of nitrates by plants is relatively slow.
