Nitrate vulnerable zones (NVZs) are areas designated as impacted, or at risk of impacts, by agricultural nitrates applied as fertilisers to boost crop yields.In the past, the process of designating an area as a NVZ has been perceived to be reliant on a limited amount of data and lacking in transparency.itrate vulnerable zones (NVZs) are areas designated as impacted, or at risk of impacts, by agricultural nitrates applied as fertilisers to boost crop yields.
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.
