Pacitan Bay is one of the semi-enclosed waters on East Java's south coast. This area well-known for having a large fishing port as well beach tourism area. The dynamics Bay's due to influence currents, waves, and input water masses from mainland are thought affect characteristics waters' bottom sediments. objective this study was map sediments distribution organic substance. research also analy...

Abstract The seabed in the ports needs to be regularly cleaned from marine sediments for safe navigation. Sediments contaminated by tributyltin (TBT) are environmentally harmful and require treatment before recycling. Treatment methods include leaching, stabilisation solidification remove toxic chemicals improve their strength reuse construction works. This study evaluated effects of adding thr...

Lake Victoria (L. Victoria) is the largest African tropical and freshwater lake, with one of highest pollution levels, globally. It shared among Uganda, Kenya Tanzania, but it drained only by river Nile, longest in Africa. Though environmental studies have been conducted investigations heavy metals (HMs) contamination sediments from fish landing sites ports on Ugandan portion L. are limited. In...

Marine sediment with an input of particulate organic matter was incubated to simulate the early aging process. On the sediment after various incubation periods, adsorption and desorption tests were conducted for three selected organic micropollutants: bisphenol A (BPA), 17α-ethinyl estradiol (EE2), and phenanthrene (Phe). The results showed significant sediment organic matter (SOM) decompositio...

Although recent studies have revealed more widespread occurrences of magnetofossils in pre-Quaternary sediments than have been previously reported, their significance for paleomagnetic and paleoenvironmental studies is not fully understood. We present a paleo- and rock-magnetic study of late Miocene marine sediments recovered from the Guadalquivir Basin (SW Spain). Well-defined paleomagnetic di...
