The present study investigated cross-media transport between both the sediment and the water column and between the water column and the atmosphere, to understand the role of each compartment as a source or a sink of polycyclic aromatic hydrocarbons (PAH) in southern California, USA, coastal waters. Concentrations of PAH were measured in the atmosphere, water column, and sediment at four water-...

In this study, a 2×3 factorial design  with two levels of  shrimp density (25 and 50 shrimp per m2) and three  levels of  red algae density (0, 200 and 400g per m2) was applied to calculate  nitrogen and phosphorous budgets in the integrated culture of Litopenaeus vannamei with Gracilaria corticata  during 45 days in a zero water exchange system. Juveniles of...

Computer simulation studies of the hydration structure and water exchange dynamics in the first hydration shell for Fe(II) in water are presented. The structure of the hydrated ion is discussed in terms of radial distribution functions, coordination numbers, and angular distributions. The average first-shell hydration structure is a 6-coordinate octahedron, in agreement with experimental result...

The traditional shrimp farming mode, which mainly uses water exchange to dilute toxic nitrogenous compounds, not only brings risks of disease infections and outbreaks but also results in waste resources has a negative impact on the environment. In this study, zero systems for Litopenaeus vannamei were constructed by using sponge biocarriers with precultured biofilms (SBBFs), effect SBBFs contro...

In present research work, anion exchange membranes based on quaternized polysulfone with ammonium cation moieties (QAPSF) were prepared by chloromethylation, amination and alkalization. The chloromethylated polysulfone were characterized by 1HNMR spectroscopy and functionalization degree was determined according to peak area integration. Ion transport properties (ionic conductivity, ion exchang...
