The characterization of dissolved organic material in natural waters and the phase-change behavior of organic matter during chemical coagulation
Research efforts pertaining to natural organic material (NOM) have focused primarily on the dissolved portion of NOM since it is the most prevalent fraction. Numerous procedures have been developed to separate dissolved organic material (DOM) into fractions but methods were not fully refined in the …

Dissolved organic material in groundwater and application of fluorescence spectroscopy coupled with EEM PARAFAC models as a means of site characterisation
The role of dissolved organic matter (DOM) in aquatic systems has been associated with numerous physiochemical processes including carbon sink, contamination indicator and important component in natural geochemical and microbial processes. However, to date research into the behaviour of DOM within …

A study of certain trace metals in sea water using anodic stripping voltammetry
… was found not to be adversely affected by dissolved organic material in sea water. Good precision (ca., 5%) was obtained in both coastal and open ocean waters at the in situ concentrations of Zn, Cu, Pb, and Cd. It was shown that this method is at present most suitable for measurements of …

Variations in modelled and measured hyperspectral remote sensing reflectance
… MODIS algorithm for the absorption by coloured dissolved organic material, αCDOM(400), provided accurate values of the absorption coefficient (R² = 0.91). Algorithm performance was improved when turbid stations, identified using cluster analysis, were removed. Hyperspectral radiometry was also …

Seaglider observations of biogeochemical variability in the Iberian upwelling system.
… “Orca” was outfitted with sensors to measure dissolved oxygen, temperature, salinity, chlorophyll a (chl a), coloured dissolved organic material (CDOM) and optical backscatter. Deployed for 113 days over summer 2010, Orca completed 17 zonal transects across the shelf, continental slope and …

Phytoplankton induced changes of air bubble residence time in seawater
… influence BRT through the production of dissolved organic material (DOM) and oxygen.<br/>Laboratory experiments were carried out in a seawater mesocosm tank system to investigate the influence of phytoplankton growth on the BRT of artificially injected air bubbles of a wide size range …

Investigation of the Interactions Among Grass, Chlorophenols and Microbes
… by which plants affect the fate of subsurface organic contaminants. The research was divided into three studies: interactions between live grasses and 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and pentachlorophenol (PCP); physico-chemical interactions between the three …
