Seasonal Variations in Interstitial Water Transuranium Element Concentrations

Article Abstract:

This study examines porewater concentrations of transuranium elements Np, Pu and Am in a United Kingdom salt marsh. The study concludes that such an ecosystem, with reference to biomass, is a dynamic process.

Is coastal eutrophication out of control? although research is shedding new light on the phenomenon, it is proving difficult to manage

Article Abstract:

The seeming difficulty in managing coastal eutrophication stems from the inability or reluctance of governments to control non-point sources for nitrogen loading into aquatic systems. This results in the continued degradation of coastal areas, which is expected to bring more long-term problems in terms of fishery resources. Only an aggressive non-point source nitrogen control measure can help reduce the further degradation of coastal ecosystems, such as the measures utilized by Florida in rehabilitating Tampa Bay, which required such measures as using tertiary wastewater and sewage treatment.
