🎯
Objective & Hypothesis:In this study, the sediment respiration ratios were aimed to determine in the Coruh River flowing from the city of Artvin to Georgia and flowing into the Black Sea from Batumi, Melet River flowing into the Black Sea from the city center of Ordu and the Harşit Stream flowing into the Black Sea from Giresun province Tirebolu district center. "Sediment respiration" is a good indicator of pollution which was increased due to sedimentation caused by organic substances in the water environment and precipitation of contaminant elements in the mud floor.

Abstract

In this study, the sediment respiration ratios were aimed to determine in the Coruh River flowing from the city of Artvin to Georgia and flowing into the Black Sea from Batumi, Melet River flowing into the Black Sea from the city center of Ordu and the Harşit Stream flowing into the Black Sea from Giresun province Tirebolu district center. "Sediment respiration" is a good indicator of pollution which was increased due to sedimentation caused by organic substances in the water environment and precipitation of contaminant elements in the mud floor. Sampling in the study started in February 2015 and the field study was completed in the same season. The study is planned to evaluate the respiration capacities of sediment and compare the mentioned water resources, and it was evaluated by laboratory studies using soil respiration circle. For the study, the samples from the top 5 cm of sediment layers were collected from Coruh River; Melet River and Harsit Stream. The microbial decomposition was monitored in each sediment segment by the respiratory circle incubated in the dark at 25 ° C and sediment respiration was measured in 1, 2, 4, 8, 12, 16, 20, 24, 28, 36. days. The mean sediment respiration values (mg CO2/g) were found as; 2.54 in Coruh River, 2.48 in Melet River and 1.97 in Harşit Stream. Together with sediment respiration values, the pH and amount of organic matter from sediment samples were determined and their statistical analysis was performed. As an average result of the measurements, the pH values of the sediment were 8.59 in the Coruh River, 8.39 in the Melet River and 8.00 in the Harşit Stream. The amount of organic matter (%) measured in the river sediments were found as 4.05, in Coruh River, 6.67 in Melet River; and 4.51 in Harşit Stream, respectively.

Özet

Bu çalışmada, Artvin ili Borçka ilçe merkezinden Gürcistan’a geçip Batum şehrinden Karadeniz’e dökülen Çoruh Nehri, Ordu il merkezinden Karadeniz’e dökülen Melet Irmağı ve Giresun ili Tirebolu ilçe merkezinden Karadeniz’e dökülen Harşit Çayı’nda sediment solunum oranlarının belirlenmesi amaçlanmıştır. Sediment solunumu su ortamındaki organik materyal ve kirletici unsurların taban çamuruna çökelmesiyle oluşan sedimantasyona bağlı olarak artacağından iyi bir kirlilik göstergesidir. Çalışmada örneklemeye Şubat 2015 tarihinde başlanmış ve saha çalışması aynı mevsim içerisinde tamamlanmıştır. Bu çalışma anılan su kaynaklarının sediment solunumun kapasitelerini değerlendirmek ve karşılaştırmak amacıyla planlanmış olup, sediment solunum çemberlerinin kullanıldığı laboratuvar çalışmalarıyla değerlendirilmiştir. Çalışma için Çoruh Nehri, Melet Irmağı ve Harşit Çayı’ndan belirlenen noktalardan üst 5 cm’lik sediment tabakası örneklenmiştir. Alınan her sediment segmentindeki mikrobiyal ayrışma bir solunum çemberi içinde 25°C’de, karanlıkta kuluçka edilmiş ve 1, 2, 4, 8, 12, 16, 20, 24, 28, 36. günlerdeki sediment solunumu ölçülmüştür. Ortalama sediment solunum değerleri (mg CO2/g) Çoruh Nehri’nde 2.54, Melet Irmağı’nda 2.48 ve Harşit Çayı’nda ise 1.97 şeklinde bulunmuştur. Sediment solunum değerleri ile birlikte sediment örneklerinden pH ve organik madde miktarı tespit edilerek istatistiki analizleri yapılmıştır. Ölçümler sonucu ortalama sediment pH değerleri Çoruh Nehri’nde 8.59; Melet Irmağı’nda 8.39 ve Harşit Çayı’nda 8.00 olarak tespit edilmiştir. Nehir sedimentlerinde ölçülen ortalama organik madde miktarları (%) sırasıyla Çoruh Nehri’nde 4.05, Melet Irmağı’nda 6.67 ve Harşit Çayı’nda 4.51 olarak tespit edilmiştir.
