The Buyuk Menderes basin is very wide and the people living here deal with farming, which increases the importance of the river to the region. The pollution of the river increases because the industry, urbanization and agricultural activities are very intense in the river basin. For this reason, the aim of this study is to map the extent of pollution of Buyuk Menderes River, to detect sources causing pollution in the river and also to suggest solutions for taking necessary precautions. Anionic detergent, phosphate, boron and heavy metal concentrations were determined in water samples taken from Buyuk Menderes River in this study. Mean concentrations of anionic detergent, phosphate, boron, copper, chrome, nickel and lead were found 0.2345 mg l -1 , 0.0181 mg l -1 , 0.8352 mg l -1 , 0.0035 mg l -1 , 0.0045 mg l -1 , 0.0247 mg l -1 , 0.0002 mg l -1 , respectively.

ÖZET: Bu çalışma Adıgüzel Baraj Gölü'ndeki deterjan, fosfat, bor ve ağır metal kirliliğini belirlemek amacıyla yapılmıştır. Ortalama anyonik deterjan, fosfat, bor, bakır, nikel, krom ve kurşun konsantrasyonları, sırasıyla 0.235 mg L -1 , 0.009 mg L -1 , 0.659 mg L -1 , 0.0048 mg L -1 , 0.0170 mg L -1 , 0.0016 mg L -1 , 0.0002 mg L -1 bulunmuştur. Bu değerler "Kıta İçi Su Kaynaklarının Sınıflarına Göre Kalite Kriterleri" ile karşılaştırılmıştır. Adıgüzel Baraj Gölü anyonik deterjan parametresi açısından II. sınıf (az kirlenmiş su), fosfat, bor ve ağır metal parametreleri açısından I. sınıf (kirlenmemiş su) olarak sınıflandırılmıştır.Anahtar kelimeler: Adıgüzel Baraj Gölü, ağır metal, anyonik deterjan, bor, fosfat ABSTRACT: This study was performed to determine of anionic detergent, phosphate, boron and heavy metal pollution in Adıgüzel Dam Lake. The average concentrations of anionic detergent, phosphate, boron, copper, nickel, chromium and lead were found 0.235 mg L -1 , 0.009 mg L -1 , 0.659 mg L -1 , 0.0048 mg L -1 , 0.0170 mg L -1 , 0.0016 mg L -1 , 0.0002 mg L -1 , respectively. These values were compared with "Quality Criteria for Inland Water Resources by Class". Adıgüzel Dam Lake was classified as II. class (less contaminated water) in terms of anionic detergent parameter and I. class (uncontaminated water) in terms of phosphate, boron and heavy metal parameters.

In the present study, the Marine Floristic Ecological Index (MARFEI) was tested to assess the impacts by using marine benthic macrophytes and pressures by using the Macroalgae-Land Uses Simplified Index (MA-LUSI) in the Marmara Sea (Turkey). Sampling of benthic macrophytes was made from 0-5 m depth at 29 different sites during the summer periods of 2017, 2018 and 2019. The study revealed good ecological status class (ESC) for 6 sites, moderate for 11 sites, poor for 8 sites and bad for 4 sites. MARFEIeqr showed a negative linear relationship with the pressure index MA-LUSI.
