In this study, it was aimed to examine the relationships among chlorophyll-a, environmental parameters such as temperature, salinity, pH and dissolved oxygen (DO) and nutrients Total Nitrogen, Total Phosphorus, Ammonia-nitrogen and Silicate (TN, TP, NH4 and SiO2, respectively) between 8 July and 6 August, 2004 in Sari ay Creek. During sampling periods, temperature values followed the usual seasonal values, while DO and pH changed considerably, and ranged between 1,23-13,1 mg l(-1) and 7,48-9,33, respectively. Chlorophyll-a concentration changed between 0,98-34,45 mu g l(-1), while TP, TN, NH4 and SiO2 ranged between 0,21-0,91 mg l(-1), 4,78-107,24 mg l(-1), 0,04-3,68 mg l(-1), 0,16-22,4 mg l(-1), respectively There was no significant correlation among chlorophyll-a and nutrients. However, there was significant correlation between environmental parameters, such as pH (p=0,23), temperature (p=0,28), DO (p=0,23) and chlorophyll-a (p<0.01). Results of the environmental parameters indicated that the pollution level increased irregularly in a short time and there was on instant reverse relation between inorganic nutrients and chlorophyll-a.
