The purpose of the study is the development of methodological support for the determination of rare earth elements (REE) in workplace air and biological media (blood) of workers. New methodical guidelines for the determination of REE in the workplace air and whole blood in a wide range of concentrations by the method of inductively coupled plasma mass spectrometry are presented. It is proposed to use these methods for production control at the
enterprises of mining and metallurgical industries. Also it is recommended to use the test for the determination of
REE in biological media (blood) of workers to assess the sufficiency of measures for organizing safety and reducing
harmful production factors, along with monitoring the air quality of the working area. The methods are included in
the Federal Register of Measurements: FR.1.31.2018.31642 for the cerium group; FR.1.31.2018.31641 for the yttrium group in the air of the working area, patent No. 2697479; FR.1.31.2019.32618 for the determination of REE
in blood, patent No. 2696011.
The developed methods meet the modern requirements of standardization and metrological certification, they have
high sensitivity and selectivity. The methods have been successfully approbate at a metallurgical enterprise for determining the concentrations of REE in the blood of workers and in the workplace air.
