We have developed a simplified microwave digestion method for the analysis of trace metals in fish tissue (fish collected from waters impacted by mine drainage) that utilizes small samples of intact fish tissue. Four to five samples ranging in mass from 0.2 to 0.7 g (wet weight) were digested with concentrated nitric acid and analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The volume of nitric acid used is approximately 5 mLs of either trace metal grade or reagent grade. Metals analyzed for in this study include arsenic, cadmium, chromium, copper, lead, manganese, silver and zinc. Rhodium is used as an internal instrument performance standard. The method utilizes a four point calibration curves with concentrations ranging from 1-30 microgram per L (ppb).  Detection limits for this method are in the low microgram per kg range.
