PARTISI KIMIAWI Cu DAN Fe PADA SEDIMEN PERMUKAAN DI PESISIR TIMUR DAN BARAT SUMATRA UTARA

Abstract: Mobilitas (termasuk proses desorpsi-absorpsi) logam berat dalam sedimen bervariasi yang bergantung pada asosiasinya pada komponen mineral dan non-mineral sedimen yang dapat juga mengindikasikan pada sumber alami dan non-alami. Penelitian ini bertujuan mengungkap kemungkinan sumber logam berat Cu dan Fe berdasarkan fraksinasi dan total logam. Lokasi penelitian terdiri dari 11 titik yang terbagi menjadi tiga bagian pesisir timur, pesisir barat, dan Pulau Nias, Sumatera Utara. Fraksi geokimia diperoleh berdasarka… Show more

“…Quantification of the geochemical partitioning of heavy metals in sediments is necessary to understand the nature of the metals in sediments. The nature and bonds of metals in sediment were analyzed using a geochemical partitioning method of the sequential extraction process (SEP), proposed by the European Community Bureau of Reference (BCR), or the BCR-SEP procedures used in many studies [22][23][24][25][26]. The geochemical partition method has been applied in many studies to provide information such as i) characteristics of pollution sources, ii) evaluation of bioavailability and metal mobilization, and iii) identification of metal binding to assess metal accumulation, pollution, and transport mechanisms [27,28,29].…”

“…Adapun kawasan industri yang berpotensi menyebarkan logam berat tembaga di sekitar Tambak Lorok seperti keberadaan Pembangkit Listrik Tenaga Uap (PLTU) Tambak Lorok yang berpotensi menghasilkan limbah persenyawaan logam berat seperti Cu, Pb, Zn dan lain sebagainya (Naja et al, 2019). Pencemaran logam berat yang masuk kedalam perairan akan mengalami pengendapan, pengenceran dan dispersi kemudian diserap oleh organisme hidup di perairan karena logam berat memiliki sifat persisten (Yolanda et al, 2019). Logam berat Tembaga dapat masuk kedalam tubuh manusia melalui rantai makanan, apabila manusia mengkonsumsi biota yang terdapat di kawasan tercemar logam berat Cu maka konsentrasi logam berat tembaga akan mengendap di tubuh manusia.…”
