More than 250 water samples from lakes in the Eastern US were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) for 49 elements. Standard calibrations were used for 21 elements, and surrogate standards were used for 28 elements. The system detection limits, evaluated by using field blanks carried through the entire sampling and pretreatment process, were less than 0.2 ..mu..g/L for most elements. Contamination during sampling and pretreatment was often the limiting factor. The accuracy of the determinations, as determined from the analysis of NBS SRM 1643b samples and by recoveries for spiked water samples, was typically better than /plus minus/ 10% for the elements determined by using standard calibration and better than /plus minus/ 25% for the elements determined by using surrogate standards. The long-term (12 months) precision was generally better than /plus minus/ 10%, expressed as relative standard deviation, for both methods of determination. The use of surrogate standards and interference corrections is discussed in detail.
