Accuracy, Precision, and Detection Limits — Analytical cost, accuracy, precision, and detection limits are the four main evaluation criteria for selecting an analytical method. Detection limit information will not be givdn here, as it is easily obtained from the literature or from instrument manufacturers. The analysis of NBS orchard leaves and bovine liver is often used to demonstrate the accuracy and precision of ICP analysis. We feel that the analysis of United States Geological Survey (USGS) and Canadian Centre for Mineral Energy Technology (CANMET) standard rocks, is a more rigorous test of ICP analytical accuracy because of the resistance to sample... 

A summary of the levels of POPs contamination reported in the environmental media (ambient air, surface water, sediment and soil, and vegetation) of Hong Kong in 2000 2004 is presented in Table 7.4. The mean environmental levels of POPs were weighted arithmetic sample means calculated based on samples analyzed and reported in individual studies. If the level of a POP chemical was found to be below the analytical method detection limit (DL) in all samples analyzed in a particular medium, the mean value was reported as 0 . If a measurable level (i.e., >DL) of a POP chemical was reported in some or all samples analyzed in a particular medium, the mean value was calculated by assuming a value of 0.5DL for sample levels of [Pg.328]
