Excessive
nitrates can cause acidification of water and also led
to a large number of phytoplankton multiplication
(commonly known as algal blooms), these phenomena is
called the river or reservoir "eutrophication."
NO3
become
nitrate when meeting NO2
and
O2
in
the water. Basically NO3
must
exist in the water that has sufficent O2.
Have
to pay attention if the total number is more than
10ppm.
