Nitrogen Flashcards
1
Q
Sources and Losses
A
Sources -atmosphere -Precipitation (NOx) -particulates -Sewage, agricultural run-off, groundwater Losses -Burial -outflow -denitrificationq -Anammox
2
Q
Forms of nitrogen
A
DIN: Dissolved Inorganic nitrogen
DON: Dissolved Organic nitrogen
-compounds
Particulate organic nitrogen
– living and dead matter or bound to
inorganic particles
3
Q
Nitrogen fixation
A
High energy process
Converts DIN to PON
May be suppressed when other forms of N available, low phosphorous, high turbulence
4
Q
Ammonification
A
PON–> Ammonia
5
Q
Denitrification
A
Removes biologically active Nitrogen
energy intensive, mostly happens in a high activity areas
6
Q
Nitrification
A
Creates energy
