Abstract

In this study, which was carried out to determine the current status of the conditions causing mucilage in the Marmara Sea, ten seawater samples were taken from the study area. Heavy metal analyzes were performed on the samples taken with the ICP-OES device. And pH, temperature, salinity and dissolved oxygen analyzes were made instantly. Considering the heavy metal analysis results, it is seen that sea water criteria are met in the sample locations. When the analysis results are examined according to the Harmful Substances Prohibited from Being Spilled into Inland Waters and Marine Production Sites and the Acceptable Values for the Receiving Environment, it is seen that Ca, Mg and K values exceed the limit values in all locations. It is also noteworthy that the dissolved oxygen values are low in the sample locations.

Tekirdağ ile İstanbul Arası Marmara Denizi'nde Müsilaj Tehlikesinin Araştırılması

Abstract

Marmara Denizi’nde müsilaja neden olan koşulların güncel durumunun belirlenmesi için yapılan bu çalışmada çalışma alanından on adet deniz suyu numunesi alınmıştır. Alınan numunlerde ICP-OES cihazı ile ağır metal analizleri yapılmıştır. Ve anlık olarak pH, sıcaklık, tuzluluk ve çözünmüş oksijen analizleri yapılmıştır. Ağır metal analiz sonuçlarına bakılığında numune lokasyonlarında deniz suyu kriterlerinin sağlandığı görülmektedir. İç Sulara Ve Denizlerdeki İstihsal Yerlerine Dökülmesi Yasak Olan Zararlı Maddeler Ve Alıcı Ortama Ait Kabul Edilebilir Değerlere göre analiz sonuçları incelendiğinde Ca, Mg ve K değerlerinin bütün lokasyonlarda sınır değerlerini aştığı görülmektedir. Ayrıca numune lokasyonlarında çözünmüş oksijen değerlerinin düşüklüğü dikkat çekicidir.
