Özet
Ergene River Basin, which is located in the north-west part of Turkey, is the most significantaquatic habitat of Thrace Region. In addition to the presence of important lentic ecosystems in thebasin, there are also important natural and artificial lotic ecosystems, which are of great importanceboth for the natural life and for the local public. Thrace Region is one of the most important andfertile agricultural regions of our country and despite such a great importance of Ergene RiverBasin for Thrace Region, almost all the components of the watershed are being exposed to anintensive pollution by means of especially agricultural applications. In this research, the pesticideconcentrations in water – sediment of most significant 6 dam lakes (Altınyazı, Karaidemir,Kayalıköy, Kırklareli, Sultanköy and Süloğlu Dam Lakes) located in Ergene River Basin wereinvestigated. Water – sediment samples were taken in rainy season (spring) of 2018 from 15 stations and pesticide concentrations (174 pesticides varieties) were determined by using an LC/MS.In addition, the investigated locations were classified in terms of pesticide accumulations in waterand sediment by using Cluster Analysis (CA). As a result of this research, 3 pesticide types inwater and 18 pesticide types in sediment were detected. Carbendazim and forchlorfenuron-706were recorded as the most dominant pesticide types for water samples and propiconazole and prochloraz were recorded as the most dominant pesticide types for sediment samples. The total pesticide contents determined in both water and sediment were found to be much higher in Altınyazıand Sultanköy Dam Lakes compared to the other investigated reservoirs. As a result of CA, 3statistically significant clusters were formed both for water and sediment, which were named as“high contaminated zones”, "low contaminated zones" and "moderate contaminated zones".
