Heavy metals originating from industrial runoff, agricultural practices, urbanization, and natural geological processes persist in coastal sediments due to their low degradation rates high stability. Their cycling is influenced by sediment dynamics, water circulation, complex interactions with biological chemical factors. metal pollution demonstrates serious risks biota, including fish, shellfish, algae, marine mammals through mechanisms such as bioaccumulation biomagnification. These lead biodiversity loss, habitat degradation, reduced ecosystem functionality. Current mitigation strategies for control regulations remediation techniques show promise but face challenges implementation. Emerging technologies nanotechnology bioremediation offer innovative solutions require further validation. Knowledge gaps understanding the long-term ecological impacts of heavy contamination optimizing management diverse ecosystems. Coastal ecosystems are vital supporting providing essential services, they increasingly threatened pollution—a pervasive environmental challenge that demands urgent attention. This review investigates sources, characteristics, pathways, impacts, associated environments. The synthesizes findings recent literature, employing a systematic approach analyze anthropogenic biogeochemical governing cycling. Future research should focus on addressing these interdisciplinary approaches, integrating advanced modeling techniques, stakeholder engagement, sustainable practices. By prioritizing efforts, we can safeguard services escalating threats pollution.

Particulate suspended matter (PSM) of rivers is a significant factor for carbon, nutrient, and trace metal transfer from land to ocean. Towards better understanding the role that PSM exerts on major elements in riverine systems, here we report results an experimental study which utilizes two-fold approach assess interaction between solutes. First, measured element leaching (via desorption dissolution distilled water, simulating snow melt) largest Siberian river, Ob River. Second, quantified capacity adsorb dissolved organic carbon (DOC), macro- micronutrients organic-rich waters river floodplain. We documented sizable some metals, oxyanions insoluble PSM; majority (>50 %) were released over first hour reaction. In contrast, River was capable removing 20 90 % OC, nutrients (Si, P), tributary floodplain fen. Our experiments demonstrated preferential adsorption aromatic compounds large molecular size colloids. Taken together, solutes by can sizably decrease concentration modify distribution, therefore potential bioavailability (DOC, P, Si) micronutrients. Overall, exhibited high reactivity with respect natural modifying elemental composition fen waters. This surface-adsorbed (particulate) form especially important during spring flood requires specific consideration short-term biogeochemical cycles continental

The Guangdong-Hong Kong-Macao Greater Bay Area (GBA) is one of the most urbanized and industrialized coastal regions in China, where intense human activities contribute to substantial terrestrial sediment discharge into adjacent marine environment. However, complex hydrodynamic conditions high spatiotemporal variability pose challenges for accurate suspended concentration (SSC) retrieval. Developing water quality retrieval models based on different classifications bodies could enhance accuracy SSC inversion waters. Therefore, this study classified waters GBA clear turbid zones Hue angle α, established using a single-scattering approximation model secondary-scattering radiative transfer processes. Model validation with in-situ data shows coefficient determination (R2) 0.73, root mean square error (RMSE) 8.30, absolute percentage (MAPE) 42.00%. Spatial analysis further reveals higher around Qi’ao Island Pearl River Estuary (PRE) along coastline Guanghai Bay, identifying these two areas as priorities attention. This aims offer valuable insights management GBA.
