Usage and Effects of Algaecide in Kurtboğazı Dam Lake

Abstract

In recent years, the increased density and incidence of cyanobacteria, also known as blue-green algae, in water resources has become a growing global problem in consequence of the increasing temperature associated with climate change. The growth of cyanobacteria in dam lakes causes algae blooms and deteriorates water quality. Since it contains Methyl-Isoborneol, Geosmin and toxins, taste and odour problems in water occur and those threatens public health. Rising density of algae causes an increase in the total amount of organic carbon in water, which increases the amount of disinfection by-products. In this study, algae control applications were performed during the summer period kesin tarih parantez icinde verilmelidir. The water samples were taken before and after the algaecide application, and total organic carbon, pH, chlorophyll-a, dissolved oxygen, copper, turbidity, orthophosphate phosphorus  and total nitrogen were analysed. In order to calculate the amount and depth of the algaecide application, we determined which cyanobacterial species would be used. Copper ethanolomine is the main constituent of the algaecide so copper contamination in water has been investigated. In general, the density of cyanobacteria in bay and stagnant waters was increase before its application. According to the results of the study, appropriate doses and times are supporters to prevent algae blooms and to control sudden increases in the number of algae. In accordance with the results of the analysis, permanent copper pollution does not occur at different depths or at different points. However, a smallamount of increase in the samples taken during the algaecide effect time can be seen from time to time.
