ABSTRACT
Background:
The first stage to reduce the workers' exposure to the chemicals is a detailed identification of substances in workplaces. The aim of the study was to develop a method for determining the concentration of carcinogenic Disperse Blue 1 in workplace air.

Material and methods:
The method consists of drawing the air that contains Disperse Blue 1 through a cellulose filter, washing out the substance adsorbed on the filter with methanol and analyzing the obtained solution using high-performance liquid chromatography with a diode array detector. The determination was carried out in the reverse-phase system (mobile phase: acetonitrile:ammonium acetate solution, 45:55) using an Ultra C18 column.

Results:
The measurement range was 0.01 - 0.2 mg/m3 for a 720 L air sample. Limit of detection and limit of quantification were 0.52 ng/mL and 1.6 ng/mL, respectively.

Conclusions:
The method could be useful for determining occupational exposure to this substance in the working environment.
