Abstract :Ergene River is located in the north-west part of Turkey and it is the most significant river ecosystem of Thrace Region. It is also the most important tributaries of Meriç River that is the longest river in Balkans. Despite such great importance of Ergene River, it is being exposed to an intensive pollution by means of especially agricultural, industrial and domestic activities conducted around its watershed. The aim of this study was to determine the pesticide residues in water-sediment of Meriç and Ergene Rivers and its 10 significant tributaries. Water-sediment samples were collected in spring season insert ignore into journalissuearticles values(rainy); of 2018 from 21 stations and pesticide concentrations insert ignore into journalissuearticles values(total of 174 different pesticide varieties); were investigated in water and sediment samples by using LC/MS. According to detected data, the concentration of pesticide residues ranged from 0.0034ppb insert ignore into journalissuearticles values(propamocarb-hydrochloride in Safaalan Creek); to 12.0250ppb insert ignore into journalissuearticles values(carbendazim in Çorlu Stream); for water samples and from 0.0244ppb insert ignore into journalissuearticles values(acetamiprid in Çorlu Stream); to 1173.5320ppb insert ignore into journalissuearticles values(prochlorazin in Ahmetbey Creek); for sediment samples. It was also determined that pesticide accumulations detected in the Ergene River Basin, especially in Çorlu Stream and Ergene River, were found to be in quite high levels and the system has II–III. Class water quality in terms of total pesticide accumulations, in general. There were clear dominances of carbendazim insert ignore into journalissuearticles values(in water); and prochloraz insert ignore into journalissuearticles values(in sediment); of the entire investigated basin. Çorlu Stream insert ignore into journalissuearticles values(in terms of water); and Ahmetbey Creek insert ignore into journalissuearticles values(in terms of sediment); were recorded as the most contaminated aquatic components of the system.
