Finding F-1057

“Finally, 1-ethyl-2-methylbenzene, a by-product of varnish manufacture and a respiratory irritant, was detected at 38.28 ± 4.67 μg/m3 (PUR) and 25.27 ± 3.92 μg/m3 (ACR–PUR) in varnishes, with indoor concentrations of 0.33 ± 0.16 μg/m3 during days 14–21 and nondetectable after 60 days.”

Structure

Source: Paints and coatings
Factor: Volatile organic compounds (VOCs)
Setting: test chamber, CZ (days 14 to 21 after the coating was applied)
Study design: test-chamber study of water-based polyurethane and acrylate-polyurethane lacquers: volatile organic compounds in the coating and in chamber air 14 to 21 days and 60 days after application, with a toxicological grouping of the compounds (class 4)
Effect: mean 0.33
