Summary: | The aim of the study was to develop a selective method for the determination of nickel and its compounds in the air at workplaces, used to assess occupational exposure and compliant with the requirements for procedures of determining chemical factors in the work environment. Results: The developed determination method consists in sampling nickel and its compounds contained in the air onto a membrane filter, followed by filter mineralization with concentrated acid and the determination of nickel with the use of atomic absorption spectrometry. Conclusions: The developed method for the determination of nickel and its compounds allows for a selective determination of this substance in the air at workplaces in the concentration range of 0.014-0.56 mg/m3 and 0.007-0.28 mg/m3 for an air sample with a volume of 720 l. It allows for the determination of this substance from 1/10 to 2 MAC values for the current mandatory value of 0.25 mg/m3 as well as for the 2.5 times lower hygienic standard proposed to be introduced by 2025 as binding limit value in the EU.
