Article Abstract

Geosynthetic materials are applied in measures for coastal protection. Weathering or any damage of constructions, as shown by a field study in Kaliningrad Oblast (Russia), could lead to the littering of the beach or the sea (marine littering) and the discharge of possibly harmful additives into the marine environment. The ageing behavior of a widely used geotextile made of polypropylene was studied by artificial accelerated ageing in water-filled autoclaves at temperatures of 30 to 80 °C and pressures of 10 to 50 bar. Tensile strength tests were used to evaluate the progress of ageing, concluding that temperature rather than pressure was the main factor influencing the ageing of geotextiles. Using a modified Arrhenius equation, it was possible to calculate the half-life for the loss of 50% of the strain, which corresponds to approximately 330 years. Dynamic surface leaching and ecotoxicological tests were performed to determine the possible release of contaminants. No harmful effects on the test organisms were observed.

As climate change, urbanization, and marine exploitation intensify, understanding nearshore island ecosystem services (IESs) is essential for ensuring ecological protection and sustainable development. This study maps the spatiotemporal dynamics of six key ecosystem services (ESs) across 295 nearshore Chinese islands, including food production (FP), water yield (WY), soil conservation (SC), carbon storage (CS), and habitat quality (HQ) (2000-2022), and tourism and recreation (TR) (2012-2022). Using spatial autocorrelation, Slope trend analysis, per-pixel Pearson correlation, and K-means clustering, the study quantifies the trade-offs and synergies, identifies constraint characteristics, and delineates ecological functional zones for island classification.

Despite global phase-out initiatives, legacy polychlorinated biphenyls (PCBs) remobilize in marine ecosystems as secondary emission sources, posing ecotoxicological and human health risks emerge through cross-trophic dietary exposure pathways. This study aimed to systematically examined the distribution, trophic transfer properties, and health risks of PCBs in six fish and eight invertebrate species from the Beibu Gulf in southern China, by stable isotope analysis, hierarchical cluster analysis, and Monte Carlo simulation. The ΣPCBs concentrations ranged from 0.
