Finding F-1061

“The most prominent decrease in frequency was observed for benzene, which was present in quantifiable concentrations in nearly all the samples (98%) in 2010 but in only half of the samples (49%) in 2019.”

Structure

Factor: Benzene
Setting: office, FI (2010 against 2019)
Study design: analysis of the volatile organic compound measurements the Finnish Institute of Occupational Health made in offices, schools, kindergartens and healthcare buildings between 2010 and 2019: detection frequencies, 95th and 99th percentiles and maxima of 42 compounds against German and European guideline values (class 4)
Effect: other
Caveat: a detection frequency, not a concentration
