Copper and cadmium are determined frequently by most participants in this study, and results for these two metals were satisfactory as for a previous study using standard atomic absorption techniques. Precision for aluminum was fair, with a non-zero blank reading, likely picked up from the glassware. Most participants determine aluminum rarely; some had switched methods recently. Satisfactory results for strontium were obtained by seven laboratories using atomic absorption and by five laboratories using flame emission spectroscopy. The automated method used by the Water Quality Branch (WQB) demonstrated greatly improved precision and accuracy for mercury compared to a previous study, whereas the variety of manual methods used produced many outliers"--Abstract, page v. |
