A study on some microbial indices and nutrient matters in the southern part of Caspian Sea; Guilan province
The microbial pollutions and nutrient matters of the southern part of Caspian Sea is to be under close scrutiny as it is vital to tourist health and environmental conservation. In this research, some physico-chemical factors, nutrient matters, oxygen demand parameters and microbial indices were investigated. Sampling from nine sites along Astara to Chaboksar coastline were conducted with five replicates. The mean of temperature, Salinity, pH, phosphate, and nitrate, FC, TC, BOD5 and COD were respectively obtained as 22.48°C, 8.5ppt, 8.27, 0.43mg/l, 2.21mg/l, 144MPN/100ml, 626.9MPN/100ml, 3.58mg/l and 9.43 mg/l. Maximum levels of nutrient matters were measured at Anzali and Kiyashahr sites. Results showed there are positive correlations between nutrient matters as well as COD with microbial indices. The average of microbial indices at nine sampling sites were higher than the permissible level of national and international organizations for swimming places. Due to high level of microbial pollution at Anzali and Chobar sampling sites, the swimming places of these areas require specific administration.
