“…Regarding pollution simulation, in some cases, models are used to identify pollution sources through back-tracking [76]. Most applications focus on riverine environments, where high levels of pollution are identified [77,78]. In this case, the flow velocity, freshwater characteristics, and sediment behavior dominate the distribution mechanism of pollutants.…”

Water quality modeling is a key element for the support of environmental protection and policymaking. The aim of this work is to describe the application of a far-field water quality model for the simulation of marine pollution occurring from heavy metals (cadmium, lead, nickel, copper, and zinc). The highly stressed marine area of the Saronikos Gulf (Aegean Sea, Eastern Mediterranean) was chosen for investigation. Major pollution sources were identified, loads were estimated, and the model was parameterized to reproduce the local seawater conditions. The distribution of the pollutants between the dissolved and particulate phases was examined. The performance of the model set-up was evaluated using field concentration measurements. The described implementation succeeded in reproducing the observed levels of pollution and therefore can be used as a baseline configuration to examine the cumulative impact of future pollution sources; for example, accidental pollution events.

Holothuria atra (Echinodermata: Holothuroidea) is a type of invertebrate animal that lives on the bottom of the rocky coast and has the potential as a nutritious food raw material for humans and pharmaceutical raw materials. The study aims to determine the microplastic types, microplastic functional groups and simulate the distribution pattern of ingested microplastics in the digestive system of H. atra based on hydrodynamic activity. Microplastic separation was conducted by extraction using the flotation method based on predetermined criteria. Functional group test of microplastic polymers ingested in intestines of sea cucumbers using FT‐IR (Frontier Transform Infrared‐Spectroscopy) Analysis. Hydrodynamic modeling analysis used secondary data: bathymetric, currents, wind direction, and tidal prediction data. The results of sampling of H. atra sea cucumbers at four observation locations, where ten individual sea cucumbers were taken from each location, showed that microplastic waste exposed in the intestines of sea cucumbers obtained an average value of 14,166 individuals‐1, with a particle length range of 0.214–3.978 mm. The highest abundance was from the type of fiber, followed by fragments, pellets, and films. FTIR test results indicate the presence of several functional microplastic groups that are digested in the intestine, including polyamide (PA)/nylon‐6, polyethylene (PE), polypropylene (PP), and polystyrene (PS). The movement of currents carrying microplastic waste particles is dominated to the west and south of Karimunjawa Island, potentially endangering the habitats of sea cucumbers and other animals in the waters of the surrounding small islands. It is recommended that stakeholders establish plastic waste protocols, waste facilities and treatment, and strict supervision of tourists entering the Karimunjawa tourism environment.

The release of hazardous elements by industrial effluents to aquatic ecosystems is a potential threat to the environment. Chromium (Cr) is one of the elements whose levels in several freshwater ecosystems should be reduced to promote water reuse. In recent years, magnetic materials have gained increasing interest as sorbents because of their easy removal from treated water through magnetic separation. In this study, colloidal cobalt ferrite (CoFe2O4) particles were investigated as magnetic sorbents for chromium-aqueous chemical species. The oxidative stress responses of Mytilus galloprovincialis mussels exposed to 200 μg/L of Cr, resembling remediated water, were evaluated. More than 95% of Cr was removed from contaminated solutions by CoFe2O4 aqueous suspensions at pH 6 and pH 10. The kinetics of sorption experiments were examined using pseudo-1st order, pseudo-2nd order and Elovich models to evaluate which mathematical model has a better adjustment to the experimental data. The present study revealed that the levels of Cr that remained in remediated water induced limited biochemical changes in mussels, being considered safe for aquatic systems. Overall, the use of cobalt ferrite–based sorbents may constitute a promising approach to remediate contaminated water.
