The application of atomic absorption spectroscopy to trace copper analysis in fats was investigated. Copper spectral resonance lines 3248 A and 3274 A possess the most useful sensitivities applicable to fats and vegetable oils. These sensitivities were determined to be 0.15 and 0.25 ppm in oil, respectively, with detection limits about tenfold lower. Data show that copper absorption depends str...

In this issue of Clinical Chemistry, an electrochemical method is described for the simultaneous measurement of cadmium and lead in whole blood. Exposure to these toxic metals is an inevitable consequence of life in industrialized society. Blood Pb is currently measured, with little interlaboratory disagreement, by atomic absorption or electrochemical methods. In contrast, despite numerous atte...
