Rapid digestion and flameless atomic absorption spectroscopy of mercury in fish.
A rapid method is described for the determination of total mercury in fish samples. The sample is digested with nitric acid-sulfuric acid-potassium permanganate, and then reduced and aerated for measurement by flameless atomic absorption spectrophotometry. The average recoveries of organic and inorganic mercury added to fish were 93 and 95%, respectively. The uniformity of mercury levels in shark tissue has also been investigated.
