Finding F-1155

“In this study, although the calculation method for the TVOC and ΣVOCs slightly differ, the ΣVOC levels of 20 samples (13 %) were above the interim target value for the TVOC (400 μg m− 3).”

Structure

Factor: Total volatile organic compounds (TVOC)
Setting: home, JP
Study design: study of Japanese homes: 75 target volatile organic compounds sampled indoors, the samples clustered by their compound composition, and the clusters compared with the symptoms the occupants reported (class 4)
Effect: share-above 13
Caveat: the summed compounds and the total volatile organic compounds are not calculated the same way, as the authors note
