Abstract

The Caspian Sea is one of the most polluted aquatic ecosystems in the world, currently surrounded by five countries including Iran, Russia, Azerbaijan, Kazakhstan and Turkmenistan with Iran located on the southern side. Considering the important features of the Caspian Sea and the adverse effects of water pollution on them, the present research mainly aims at determining the physical, chemical and biological features of the southern coast waters of the Caspian Sea in Gilan province, identification of its pollutants and finding ways to reduce pollution of the Caspian Sea. Water analysis for the southern coast of the Caspian Sea in Gilan province shows these variation ranges: 7-9. 95 for pH, 2-12. 8 mg / L for DO, 100-18116 mg / L for TDC, 3-8243 mg / L for TSS, 0. 01-4. 05 mg / L for N-NH4, 0. 01-2. 43 mg / L for N-NO3, 0. 001-0. 82 mg / L for N-NO2, 0. 01-0. 62 mg / L for TPO4, 0. 073-5. 65 g / L for chlorine, 3-46 x 10 6 MPN/100cc for total coliforms and 0. 21-13. 51 for salinity. Based on the studies conducted, from the Mordabroud in Astara to Hachin rood in Chaboksar, all the rivers entering the Caspian Sea are polluted. In addition, Siahrood and Goharroud rivers are the most polluted ones in Gilan province, continuously entering huge amounts of pollutants into the Caspian Sea. Many water pollutant industries in Gilan province such as Rudbar Leather Factory, Ganje Roodbar oil Factory, Chokka, Anzali Slaughter house, Foumanat Spinning and weaving industry, Pars Chinaware factory, Nik Noohs, Zamzam, Gilan meat products, Gilan spinning industry, Sobhan Pharmaceutical company, Iran Poplin And Fiber Iran enter their sewage into the Caspian Sea directly or through rivers and other waterways. Water pollution of the Caspian Sea includes chemical pollution (caused by different kinds of the wastewater, wastes, petroleum materials and their derivatives), microbial pollution (due to agricultural and industrial activities or sea water advancement) and physical pollution (resulting from construction of bridges, dams, waterfalls, soil erosion, using of agricultural water pumps and cooling installations and radioactive substances). Now the water quality of the Caspian Sea and its rivers has been deteriorated so that it is insalubrious for humans and aquatics.
