Yağlıdere Çayı (Giresun) Sediment Kalitesinin Belirlenmesi

Sucul ekosistemlerde sediment endüstriyel ve tarımsal deşarjlar, evsel atıklar, atık su arıtma tesisleri ve yağmur gibi doğa olayları sonrasında çeşitli kirleticiler tarafından sıklıkla kirletilmektedir. Bu etkilerinden dolayı sucul ekosistem ve insan sağlığını korumak için sediment kalitelerinin geliştirilmeye ihtiyacı vardır. Bu çalışmada Yağlıdere Çayı'ndan 5 istasyondan toplanan sediment örneklerinde bazı metallerin (As, Se, Ag, Cd, Na, K) pH, elektriksel iletkenlik, (%) su içeriği ve (%) organik madde miktarı analiz edilmiştir. Elde edilen veriler ile yerkabuğundaki iz element miktarlarından faydalanılarak Jeoakümülasyon İndeks değeri tahmin edilmiş ve örneklerin çoğunda antropojenik etkinin varlığı belirlenmiştir. Sonuç olarak, çalışma alanında K, Na, As ve Se'nin baskın olarak biriktiği gözlemlenmiştir. Bu metaller Yağlıdere Çayı'nda olumsuz etkiye sahip ve çevresel risk yaratabilir.Sediments in aquatic systems are often contaminated by various pollutants originating from the sources such as industrial and agricultural discharges, municipal wastewater treatment plants, and storm water. These effects lead to the need to develop sediment quality objectives regarding the protection of aquatic ecosystems and human health. In this study, the sediment samples were collected from five sampling sites and then analyzed in order to identify the concentrations of certain metals (As, Se, Ag, Cd, Na, and K), the levels of pH, conductivity, water content (%) and organic matter (%) in the Yağlıdere Stream. Finally, Geo-accumulation index values calculated based on the estimations regarding the background trace element concentrations suggested the anthropogenic influences in most of the samples. In conclusion, it was observed that K, Na, As, and Se dominantly accumulated in the study area. These metals may have a negative impact on the research area and create an environmental risk
