Abstract

Anionic detergent, phosphate and chlorophyll-a concentrations were evaluated in Istanbul Strait between January 2013 and December 2014. Water samples were taken monthly at one station in the strait. The average concentrations of phosphate were 1.38 mg L-1 for surface water and 1.76 mg L -1 for bottom water in 2013, 236 mg L -1 for surface and 3.21 mg L -1 for bottom in 2014. The average values of chlorophyll-a were evaluated as 1.42 μg l-1 for surface water and 1.02 μg l-1 for bottom water in 2013, 1.22 μg l-1 for surface water and 1.25 μg l-1 for bottom water in 2014. The mean value of anionic detergent was found to be 0.042 mg l-1 in the surface water and 0.051 mg l-1 in the bottom water for 2013 and 0.037 mg l-1 in the surface water and 0.042 mg l-1 in the bottom water for 2014. The highest pollution was found in July 2013 and August 2014. There were no significant differences in the concentrations of anionic detergent, phosphate and chlorophyll- a within the two years and depths (p>0.05).
