By Amina Nazarli
The National Monitoring Department on Environment of the Environment and Natural Resources Ministry of Azerbaijan has conducted a monitoring on the rivers Kur and Araz in the first decade of February.
The monitoring was aimed to study the level of pollution of the rivers and their branches, AzerTag state news agency reported.
The monitoring results revealed that the water flow due to the
impact of untreated waste water and sewage industry dropped on the
territory of Georgia and Armenia to the water, the amount of
biogenic substances in the Kur River and its tributaries is much
higher than normal, the Ministry said. The level of phenol and
copper in the water has exceeded the norm in Aghstafachay River
either.
A similar situation was observed in the Aghstafachay reservoir,
Shikhli-2, as well as Araz River - Horadiz, Birinji Shahsevan,
Bahramtapa points.
The oxygen regime of water at all points ranges within health
standards.
The Ministry regularly conducts monitoring and studies of the two
rivers and often the results are not encouraging.
The amount of nutrients, the composition of specific contaminants of phenol and copper compounds have exceeded the norm repeatedly over the years, and the situation has not changed so far.
Experts regard phenol as one of the most dangerous types of industrial waste. Phenols are one of the most common pollutants entering surface waters with sewage from plants.
