Description:Characterization and Quantitation of Personal Exposures to Epoxy Paints in Construction Using a Combination of Novel Personal Samplers and Analytical Techniques Identifying Agents of Epoxy Resin Exposure Among Construction Painters
Yalong Xue, Anila Bello, and Dhimiter Bello. Annals of Work Exposures and Health, 2021.
Epoxy resins appear commonly in products used in construction, including coatings, adhesives, primers, and sealers. Occupational exposures to epoxies can cause allergic contact dermatitis, occupational asthma, hypersensitivity pneumonitis (epoxy-resin lung), and acute decline in lung function. However, there has been limited data collected about quantitative exposure to epoxy resins and limited methods for monitoring exposures in real-world applications. The researchers aimed to develop and implement two new complementary quantitative analytical methods — liquid chromatography–tandem mass spectrometry with online ultraviolet detection and ion chromatography. They applied both simultaneously to characterize products and measure respiratory and skin exposures from epoxy resins among construction painters during bridge painting. They measured workplace exposures to the main component in commercial epoxy resins, bisphenol A diglycidyl ether (BADGE), and its two oligomers (dimer and trimer).
