Экологическая ситуация Северной части Каспийского моря

In the frame of the current Project the estimation on contents of nutrients, petroleum hydrocarbons, phenols and heavy metals in water and bottom sediments in the basins of rivers Terek, Sulak and Samur over the last years was carried out. Research was conducted within a framework of the State Monitoring Programme on Roshydromet in the central and lower parts of the Terek delta. The data of Roshydromet standard investigations was used to assess the concentration of pollutants, namely petroleum hydrocarbons, heavy metals, phenols, detergents, nutrients (nitrites, nitrates, ammonium and total nitrogen) and silicates, and also expenditure of river water during the estimation of their flows at hydrological Karagalinsky hydro system and
Alikazgan stations in the Terek delta. The Roshydromet data cover the period 2002-2005.
