with mineral forms of nitrogen. General vewing during the last 10 years
showed decreasing of levels of nitrogen pollution but it is quite
high.
AZOV SEA
There is a situation of increasing of mineral
nitrogen in the Azov sea area. There is a situation of high level of mineralization
in waters aroud of the Azov sea. Contents of nitrogen compounds is also very high (in 2000):
• for NH4 compounds - from 1 to 9 times of MPC
(maximum permissible concentration)
• for
NO2 compounds – from 1 to 34 times of MPC
Contents of nitrogen compounds in the Azov sea is low
– less than 1 MPC.
Contents of petroleum products in the waters – from 1
to 2 MPC.
Contents of phenolic compounds – about 3 MPC.
