Nitrogen-containing compounds act as nutrients in streams and rivers. Nitrate reactions [NO3-] in fresh water can cause oxygen depletion. Thus, aquatic organisms depending on the supply of oxygen in the stream will die.acteria in water quickly convert nitrites [NO2-] to nitrates [NO3-]. Nitrites can produce a serious condition in fish called brown blood disease.. Nitrites also react directly with hemoglobin in human blood and other warm-blooded animals to produce methemoglobin.
