Key Points

The study aims to develop a more effective sampling method for measuring 4-aminophenol in workplace air.
Developed a sampling method using 360 L of air at a flow rate of 2 l/min.
Tested various filters for their ability to retain the inhalable fraction of 4-aminophenol.
Utilized acetonitrile for extracting 4-aminophenol from the filters.
Analyzed extracted samples using chromatography.
Achieved good precision and accuracy in detecting 4-aminophenol.
Method met the requirements of European standard EN 482 for chemical agent determination.
Pre-verified at a cosmetics manufacturing company.

Implication

Analytical method determines 4-aminophenol levels in workplace air, indicating exposure risks for workers.
