Applications of inductively coupled plasma atomic emission spectrometry in occupational health

Abstract

Inductively coupled plasma atomic emission spectrometry was applied to the determination of metals and metal compounds in samples collected in the workplace for the assessment of occupational exposure of workers. The procedures used to determine a wide range of elements in air sampling filters, dusts, ashes and paints are described. Different hot-plate and microwave-assisted digestion procedures were evaluated. Accuracy, precision and long-term reproducibility of the methods are presented. Quality control and quality assurance approaches used for these types of analyses are discussed and the results are reported.
