Table 2*. Average concentrations of trace elements in parts per million based on triplicate analyses.
[Bracketed values are averages of two analyses, and nubmers in parentheses are based on only one analysis. Data from high-precisino techniques are in bold except outliers. An * indicates that the analysis was done in Denver. Complete data set is given in appendix 1. Material analyzed: (A) = ash, (C) = whole coal. -- no data]
