Mercury Determination in Fish by CVAF Spectroscopy 9

From Teledyne Instruments
 

 
Mercury is a toxic element with harmful effects that are well documented and understood. The consumption of fish is the primary source of mercury absorption for the general public. Because fish can bio-accumulate mercury, unacceptably high levels of mercury appear in fish taken from pristine waters. Fish tissue sometimes can be more than 100,000 times more concentrated in mercury than their indigenous waters. Often, warnings related to fish in specified bodies of water or to certain species of fish limit recommended consumption for the entire population or those at high risk such as women of child-bearing age. This technical note describes the determination of mercury in fish tissue using a fully automated cold vapor atomic fluorescence analyzer.
