İzmir Karaburun Bölgesinden Alınan Deniz Sedimentlerinin Ağır Metal Analizi

Abstract

Bu çalışmada İzmir Karaburun bölgesindeki deniz sedimentleri analiz edilerek bölgedeki ağır metal kirliliğinin tespit edilmesi amaçlanmıştır. Sediment örnekleri sondaj yöntemi kullanılarak altı farklı bölgeden alınmış ve lazer indüklenmiş plazma spektroskopi (LIBS) yöntemi kullanılarak analiz edilmiştir. Cihazda önceden kalibre edilmiş tanımlı elementler ile analiz sonucunda tespit edilen element yüzdeleri karşılaştırılmıştır. Bu karşılaştırma sonucunda %97 eşleşme oranıyla potasyum (K) elementi ve %97 eşleşme oranıyla demir (Fe) elementinin altı farklı bölgede de yoğun olduğu tespit edilmiştir. Bu elementlerin yanı sıra birinci, dördüncü ve altıncı bölgelerde, yaygın ağır metaller olarak karşımıza çıkan gümüş (Ag) elementi diğer bölgelere göre %50 gibi yüksek bir oranda tespit edilmiştir. Altı farklı bölgede de tespit edilen elementler birbiriyle benzerlik göstermiş olup, her bölgede bu ağır metallere eser miktarlarda rastlanmıştır. Yapılan LIBS analizi sonucunda tespit edilen veriler literatür ile karşılaştırıldığında, toksik element oldukları bilinen ve insan sağlığı açısından tehlikeli olarak adlandırılan civa(Hg), kurşun(Pb) ve arsenik(As) gibi ağır metallerin tespit edilmediği yada eser miktarlarda tespit edildiği görülmüştür. Bu sonuçlara göre bölgede insan sağlığına ve deniz ekosistemine tehlike oluşturabilecek bir ağır metal kirliliğine rastlanmadığı belirlenmiştir.

Analyses of Heavy Metals in Sea Sediments from the Izmir Karaburun Region

Abstract

The present study aimed to determine heavy metal pollution in the Izmir Karaburun region of Turkey by analyzing the marine sediments within the Izmir Karaburun peninsula. Sediment samples were taken using a drilling method from six different regions on the peninsula and analyzed using laser-induced breakdown spectroscopy (LIBS). The percentage of the elements in the samples that matched the standard elements described in the device were determined. The results showed that potassium (K) with a 97% matching percentage and iron (Fe) with a 94% matching percentage was intensive in six different regions. In the first, fourth, and sixth regions, silver (Ag), which is a frequent heavy metal, was found at a high incidence of 50% as regards that in other regions. The results of these analyses were parallel to each other in six different regions in the Izmir Karaburun peninsula, and amount of possibly toxic heavy metals were found. When the LIBS conclusions were compared with the conclusion found in the literature, the existence of some elements, such as mercury (Hg), lead (Pb), and arsenic (As), which are known to be toxic elements and a danger to human health, were found in only trace amount; as a consequence, we supposed that there is no heavy metal pollution that could pose a hazard to human health and marine ecosystems within that region.
