Problems associated with using filtration to define dissolved trace element concentrations in natural water samples
Article Abstract:
Results of experiments conducted by the US Geological Survey, the Geological Survey of Canada and Environment Canada suggest that other filtration-linked factors can induce variations in elements such as Ni, Fe, Co, Cu, Zn and Pb. Most of the variations are attributed to inclusion or exclusion of colloidally-associated trace elements in the filtrate. This downplays the practice of accepting lowest concentrations determined for a sample or a particular site as being the more representative.

A trace-element technique for determining nonpoint sources of contamination in freshwaters
Article Abstract:
The use of a trace-element system can determine sources of contamination in freshwaters. The technique uses eight soluble elements and can trace both pollutants and natural contaminants. Neutron activation and turbimetry are the basic analytical methods. Research methods and results are discussed.
