Oceanus-Lab has recently published a significant study titled "Metal Pollution Chronology and Ecological Risk Assessment in Marine Sediments of Perama - Salamina Strait, Saronikos Gulf, Greece," shedding light on the alarming levels of metal contamination in one of the most environmentally stressed regions of the Saronikos Gulf. Authored mainly by Anastasia Gkaragkouni as part of her PhD thesis, under the guidance of dr. George Papatheodorou, this research investigates the historical trends of heavy metal pollution, evaluates the associated ecological risks, and identifies potential sources of contamination. 

Using sediment core samples from the Perama-Salamina Strait, the study employs statistical analysis and 210Pb sediment dating to reveal a 65-year chronology of contamination. Metals such as Ag, As, Cd, Cu, Ni, Pb, Sn, and Zn were found in the upper 40 cm of sediment, linked to high sedimentation rates from multiple pollution sources. Despite a slight reduction in metal accumulation in recent years, the ecological risk remains significant. The study highlights the urgent need for continued monitoring and remediation efforts in the area.

Special congratulations to Spyros Sergiou for his contributions to the research. This paper is not only a vital step in addressing environmental challenges in the Perama-Salamina Strait but also an important contribution to marine sediment pollution research.
