Mercury Speciation


It now well documented that organomercury compounds such as methyl mercury chloride and ethyl mercury chloride are much more toxic than inorganic mercury . It is therefore important to be able to separate and measure these and other species of mercury in order to avoid a tragedy similar to that at Minamata Bay. In order to determine levels of the individual mercury species, separation techniques such as such as HPLC (usually partition or ion chromatography) and/or GC are widely used. Using suitable extraction procedures, these techniques combined with sensitive detectors such as an Atomic Fluorescence spectrometer, offer the analyst a reliable and inexpensive system for mercury speciation.
