Predicting epilimnetic phosphorus concentrations using an improved diatom-based transfer function and its application to lake eutrophication management

Article Abstract:

A new approach to lake eutrophication management use diatoms as indicators of lake trophic status. In comparison with past eutrophication methods, this approach combines six regional training sets of modern surface-sediment diatom assemblages and uses weighted average partial least squares to reconstruct environmental variables. Application of the method to reconstruct historical total phosphorus concentrations for a hypertrophic Danish lake reveals a high predictive ability.

Ethylmercury in the soils and sediments of Florida Everglades

Article Abstract:

Results of an observation show that there is an abundant occurrence of ethylmercury in soil and sediment samples from the Florida Everglades. The presence of ethylmercury, a non-MeHg+ organic mercury species, in the environment, provides insights into understanding the toxic metal's biogeochemical cycle. The observations were done through an analytic technique involving a combination of capillary gas chromatography and atomic fluorescence spectroscopy.
