Özet
Meriç River, called international water, is one of the most important river systems in Thrace. Asthe river is an open ecosystem to intensive anthropogenic impacts from settlements, agriculturaland industrial areas, monitoring its aquatic characteristics is very valuable in terms of maintainingits sustainable use. In particular, knowing the micro and macro element contents that play an important role on primary productivity in aquatic ecosystems will be very useful in predicting theeutrophication process. In this study some chemical analyzes (calcium, magnesium, chloride, nitrate nitrogen, nitrite nitrogen, sulphate, phosphate, cupper, iron, zinc) were carried out to determine the concentrations and distribution of some micro-macro elements and their derivates in Meriç River. Thus, it was aimed to determine the micro and macro element contents of different regions in the river, to compare the data with other studies in the region and to make suggestions onthe sustainable use of the river. For this aim, samplings were done selected from eight stationslocated in Meriç River at Thrace region of Turkey between January and December 2011. Chemicalanalyzes of Ca, Mg, Cl, NO3-N, NO2-N, PO4, SO4 in water samples taken from the sampling stations by the Ruttner water sampler at monthly intervals were carried out in the laboratory usingclassical and spectrophotometric methods. The multivariance analysis (Bray-Curtis Cluster Index)was used to evaluate the similarities of sampling stations in terms of seasonal averages of theseparameters. In order to determine the concentrations of some heavy metals (Cu, Fe and Zn), watersamples taken by Ruttner sampler and sediment samples taken by Ekman grab at seasonal intervalswere measured in flame atomic absorption spectrometry. The sampling stations were evaluatedalso statistically by using Bray-Curtis Cluster Index in terms of heavy metal contents of water andsediment. According to the result of statistical analysis, it was determined that the locations atlower Meriç River area are different from the upper area. Especially it was observed that the sampling locality after Ergene River added to Meriç River has very low quality level in terms of somechemical contents. It is thought that this may be due to the agricultural and industrial pollutionload carried by the Ergene River. Therefore, it has been concluded that these locations must beevaluated in the studies of physicochemical evaluation of Meriç River.
