WATER QUALITY ASSESSMENT IN SOME PONDS BY USING ALGAE IN ERBIL PROVINCE, NORTH IRAQ

Abstract

The study was conducted in three ponds within Shanader Park, Erbil, and Kurdistan region north of Iraq. Water samples were collected in polyethylene bottles and algal samples were collected in sterile vial of 50 ml. physical, chemical and biological tests were include: air and water temperature, pH, EC, total hardness, calcium, and magnesium. On the other hand, biological tests include algal identification. The results indicate that water and air temperature were 9-10, 14-15 ˚C, pH 7.95- 8.11, EC between 359-392 (S/m). Total hardness between 174-202 mg/l CaCO3 l-1, Calcium hardness between 71- 84 mg/l, Magnesium hardness between 24-28 mg/l. The results of algal identification when recorded 11 genera include: Cladophora sp., Chloroccocum sp., phormidium sp., synedra sp, Euglena sp. Chlamydomonas sp., Osillatoria sp., Lyngbya sp., Cymbella sp, Gloeotrichia sp., and Chroococcus sp. Some of them have an important role in pollution.
