Interlaboratory quality control study no. 4 : arsenic, cadmium, cobalt, mercury and nickel / D.J. McGirr and R.W. Wales. : En36-508/25E-PDF
"Synthetic samples containing arsenic, cadmium, cobalt, nickel and mercury were analyzed by nine laboratories participating in a study of trace metals. Most laboratories used atomic absorption methods for determining cadmium, cobalt and nickel; precision and accuracy were good for these three metals. Results were also acceptable for arsenic, which most laboratories determined by the silver diethyldithiocarbamate method. Both precision and accuracy were rather poor for mercury, which was analyzed by various procedures based on flameless atomic absorption; it is suggested that the laboratories should review their procedures"--Summary, page v.
