LAUSR

One-year monitoring study was performed on alkyl benzene sulphonate (LAS), phosphate, and chlorophyll-a concentrations in the Prince Islands between January and December of 2017. Surface water samples were collected monthly at one station at each island. The ranges of values of LAS, phosphate, and chlorophyll-a were found as 18.05-72.98 μg/L, 18.32-31.18 mg/L, and 0.31-6.35 μg/L, respectively, during all sampling periods throughout the islands. There were no significant differences in the concentrations of anionic detergent, phosphate, and chlorophyll-a within a year (p > 0.05), but a significant difference was observed between the stations (p < 0.05).
