Safeguarding the quality of water for human consumption involves monitoring trace level concentrations of heavy metals. Such measurements have been routinely performed in the laboratory -mostly for lack of viable alternatives for field use. The table below shows, which heavy metals can be determined using the 946 Portable VA Analyzer. Maximum concentrations currently recommended by the World Health Organization's (WHO) (Guidelines for Drinking-water Quality» are also given.
