ABSTRACT
We developed and validated a method for the assessment of thirteen separate trace and toxic elements using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Included elements were as follows aluminum, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium, tungsten, and lead. The measurements of all elements in urine samples were conducted using ICAP-Q ICP-MS in a single method. The performance characteristics of the assay were determined according to clinical laboratory standards. The assay was linear in the concentration range of 1.0 to 1000.0 µg/liter for all elements. The method was precise and accurate with limits of quantitation of 1 µg/liter for chromium, manganese, cobalt, nickel, copper, cadmium, tungsten, and lead; 2 µg/liter for iron and arsenic; 5 µg/liter for aluminum; and 50 µg/liter for zinc. This method has successfully been used for the assessment of all thirteen elements included in urine and has been shown to be effective as a simple, precise, and sensitive analytical technique for biological monitoring of urine samples. © 2018 by John Wiley & Sons, Inc.
