The report summarizes various approaches to the chemical analysis of heavy industry process materials and effluents for trace element constituents that might contribute to environmental pollution. It assesses the capabilities and costs of nuclear methods, spark source mass spectrometry, x-ray fluorescence and electron and ion microprobe spectrometry, atomic absorption spectrometry, absorption spectrophotometry, atomic emission spectroscopy, voltammetry (polarography) and potentiometry (ion-selective electrodes) for determining traces (less than 100 ppm) of He, Be, Cd, As, V, Mn, Ni, Sb, Cr, Zn, Cu, Pb, Se, B, F, Li, Ag, Sn, Fe, Sr, Na, K, Ca, Si, Mg, U, and Th in such matrices as fly ash, coal, oil, ores, minerals, metals, alloys, organometallics, incinerator particulates, slurry streams, and feeds to and from sedimentation processes. The report includes a selected bibliography of the current literature, and a review of the Standard Reference Materials available for environmental analysis.
