Unveiling the eutrophication crisis: 20 years of nutrient development in Zhanjiang Bay, China

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: June 3, 2024

Coastal eutrophication is a major issue of marine pollution. The main factors controlling must be identified to ensure effective environmental management according the respective local conditions. Zhanjiang Bay (ZJB), located northwest South China Sea, semi-closed bay influenced by complex water flows and development surrounding cities. In this study, we investigated nutrient concentrations compositions in ZJB seawater over past 20 years influencing based on several field investigations from 2006 2022 historical data. High dissolved inorganic phosphorus (DIP) nitrogen (DIN) were contributors severe long-term ZJB; however, light was observed outer bay, primarily caused chemical oxygen demand (COD) DIP. primary sources COD nutrients riverine freshwater, sewage outfalls, mariculture domestic effluents carried rivers. Tidal effects diluted with thereby playing key role redistribution. DIN: DIP ratio showed restriction excess phosphorus, owing activities. Marine undertakings can exert various impacts quality. Eliminating illegal aquaculture launching tailwater treatment improve quality, whereas practices such as channel dredging may worsen it. This study demonstrates intricate dynamics ecosystem offers valuable insights for conservation efforts.

Nitrogen availability regulates the effects of a simulated marine heatwave on carbon sequestration and phycosphere bacteria of a marine crop

Limnology and Oceanography, Journal Year: 2023, Volume and Issue: 69(2), P. 339 - 354

Published: Dec. 26, 2023

Abstract Great hope has been pinned on seaweed cultivation as being a potent way of removing CO 2 to reduce rates sea surface warming and acidification. Marine heatwaves nitrogen pollution in coastal ecosystems are serious current issues that need be better understood inform decision making policy. Here, we investigated the effects simulated heatwave carbon sequestration by an important crop species its phycosphere bacteria. Gracilaria lemaneiformis was grown ambient high conditions (14 200 μ M L −1 ). Photosynthetic rate, biomass particulate organic accumulation were significantly increased “high nitrogen‐no heatwave” conditions. In “ambient conditions, expression genes related photosynthesis down regulated seaweeds lost more dissolved (DOC) surrounding water, resulting refractory (RDOC). photosynthetic gene upregulated; bacterial abundance also can explain reduced DOC RDOC accumulation. The diversity while alleviated this effect. These findings suggest economically alga G . may lose nearshore waters during marine events, enhancing sequestration, enrichment counteractive

Abstract The massive influx of Sargassum spp . to the Mexican Caribbean coasts poses significant environmental, economic, and health challenges. This study explores potential use as a biosorbent material for contaminant removal. Some pollutants found in water bodies some coastal areas are those derived from soaps detergents, such sulfates phosphates. Therefore, capacity remove this type substance dissolved was studied. removal efficiency, both pollutants, greater than 90% when concentration 900 mg*L −1 used. be used several cycles demonstrated, maintaining its capacity. structural changes after biosorption were characterized by scanning electron microscopy, demonstrating presence phosphates on spp. work proposes an efficient, sustainable system based Graphical abstract Schematic representation using
