摘要: The release of phosphorus (P) from benthic sediments can affect the P content, nutrient status and quality overlying waters in coastal ecosystem. This study was carried out to investigate influence oxidation-reduction potential (ORP) sulfide on estuary Yuniao River, China. results showed that ferric iron-bound main burial phase sediments. concentration water increased with ORP decrease increase, displaying a significant linear correlation concentration. indicate decreased may elevate zero equilibrium concentration, enhancing capability release. And react or capture reactive iron sediments, reducing adsorption capacity accelerating Therefore, control production is important sink/source conversion
