The main aim of this study is to determine the seasonal changes of dissolved and particulate trace metals and compere according to various quality criteria in the selected rivers of the Eastern Black Sea. In this study some Physico-Chemical parameters (Temperature, pH, Conductivity), Dissolved Oxygen, dissolved and particulate metals (Mn, Ni, Cu, Zn, As, Pb) were investigated at Fırtına, İkizdere and Çağlayan streams in the Eastern Black Sea of Turkey. To perform particulate trace metals analysis water passed through 45 micron filters. After filters digested in the closed microwave digestion system (Milestone Ethosplus, İtaly) dissolved and particulate trace metals were determined using ICP-MS (inductively coupled plasma mass spectrometry). The Collosion Reaction Interface (CRI) was used during the determination of As. Both Sc and In (50 ppb) were added to all standards, blanks and samples and acted as internal standards. The results obtained were classified regarding the criteria’s of European Council Directive 98/83/EC, National Recommended Water Quality Criteria (established by US Environmental Protection Agency in 2009) and World Health Organisation (WHO, 2004). Results obtained from three streams were found to be lower than legal limits proposed by European Council Directive 98/83/EC, US Environmental Protection Agency (2009) and World Health Organisation (2004).
