Distributions of Anionic Surfactantin Sea Water and Total Organic Carbon in Bottom-Surfacesediment along theTurkish Coast of the Black Sea

Bu çalışmanın amacı; deniz suyundaki anyonik yüzey aktif madde (AYM) ve dip yüzey sedimentindeki toplam organik karbon (TOK) dağılımlarını belirleyerek organik maddelerden kaynaklanan kirliliğin değerlendirmesini yapmaktır. Karadeniz'in Türkiye kıyısı boyunca, 2010 sonbaharında toplanan sediment örnekleri TOK, 2010-Sonbahar ve 2011-Kış mevsimlerinde deniz suyu örnekleri AYM için toplanmıştır. Sonuçlara göre, deniz suyundaki AYM derişimleri, mevsime, bölgelere ve antropojenik kaynakların uzaklığına bağlı olarak değişmiştir. Genel olarak, orta ve doğu Karadeniz kıyılarına yakın istasyonlarda, AYM kış değerleri sonbahardan yüksektir. Maksimum AYM değerleri, sonbaharda Ordu yüzey suyunda ve Şile dip suyunda ve kışın Bafra yüzey ve dip suyunda ölçülmüştür. Ayrıca, Yenice nehir ağzında her iki mevsimde ölçülen yüksek AYM değerleri nehrin etkisini göstermiştir. Öte yandan, maksimum TOK değeri İğne ada sedimanında (9.73%) belirlenmiştir ve C/N oranları sediman örneklerindeki organik maddenin hem denizel, hem de karasal kaynaklarla ilgili olabileceğini göstermiştir. Kıyıya yakın istasyonların yüzey sularında, AYM değerleri, toplam askıda yük ile pozitif bağlantılı (r=0.8-0.9), pH (r=0.6-0.4) ve çözünmüş oksijen (r=0.96-0.87) ile negatif bağlantılıdır.

Karadeniz'in Türkiye Kıyıları Boyunca, Deniz Suyunda Anyonik Yüzey Aktif Madde ve Dip-Yüzey Sedimanında Toplam Organik Karbon Dağılımları

The aim of this work is to determine the distributions of anionic surfactant (AS) in seawater, total organic carbon (TOC) in bottom-surfacesedimentand to make an assessment of the organic matter pollution. Seawater samples for AS in the autumn of 2010 and winter of 2011, and bottom-surfacesediments for TOC in the autumn of 2010 were collected from the Black Sea coastline of Turkey. According to the results, concentrations of AS in seawaterwerechanged withseasons, regions and distance from the anthropogenic sources including industrial and domestic discharges.Generally, winter values of ASwere higher than autumn at the nearshore stations of the eastern and middle Black Sea coasts. Maximum AS values(except Yenice River mouth)were measuredin surface seawater of Ordu and in bottom seawater of Şile in the autumnand in surface and bottom seawater of Bafra in the winter. Additionally, the highest amount of AS in both seasons near Yenice River mouth showed the influence of the river. On the other hand, the highest amount of TOC was obtained in the sediment of İğneada (9.73%) and the C/N ratiosindicated that organic matters in the sediment samplescould berelatedtoboth marine and terrestrial sources. Anionic surfactant valueswerepositivelycorrelated(r=0.8-0.9) with total suspended solid,negatively correlatedwith pH (r=0.6-0.4) and dissolved oxygen (r=0.96-0.87) insurface seawaters of the nearshore stations.
