Effect of Calcium on Arsenic Release From Ferric and Alum Sludges and Lagoons
… cases arsenic-containing residuals are stored in lagoons and allowed to reside there for months or even years. Many parameters may affect the soluble arsenic concentration and speciation in these lagoons. The second portion of this study gives some baseline conditions for these lagoons, both with …

Groundwater levels as affected by swine waste lagoons in high water table soils
The popularity of anaerobic lagoons for use with confinement swine operations in Southeast Virginia has been increasing in recent years. These lagoons are not difficult to build and maintain and have served as a feasible method of waste disposal in the region. This area typically has a high water …

The effects and fate of selected veterinary antibiotics in two Missouri anaerobic swine lagoons
… the effects and fate of antibiotics in anaerobic lagoons commonly used for waste treatment and storage. This work focused on the inhibition of methanogenesis by antibiotics, sorption of antibiotics to lagoon sediments, and hydrolysis, abiotic and biotic degradation of antibiotics in two central …

Marine influence on juvenile fish trophic ecology and community dynamics in Maryland's northern coastal lagoons
Marine influence on Maryland's juvenile lagoon fish community was examined under varied levels of internal and external forcing. In 2009, stable isotope analysis showed increasing marine carbon dependency by bay anchovy with decreasing distance to the marine inlet. Following large seagrass losses, …

Recruitment of Blue Crab, <i>Callinectes sapidus,</i> Postlarvae to the Back-Barrier Lagoons of Virginia's Eastern Shore
… of the species' range. In Virginia's coastal lagoons, planktonic blue crab megalopae are most abundant at night on flooding tides, and are not abundant during the daytime or on ebbing tides. This appears to enhance retention within the lagoons, despite the short residence time of water in the …

Vulnerability analysis and new tools for climate change adaptation of marine and lagoon systems
… Among its coastal marine environments, coastal lagoons play a crucial ecological role due to their strategical position between land and sea. However, due to their characteristics, they are particularly vulnerable to climate change, considering them as "sentinel systems" (Eisenreich, 2005; Brito …
