Finding F-1217
“However, the TWA values are below the guideline limit value of 100 μg/m3 [1].”
Structure
- Source
- Candles and incense
- Factor
- Formaldehyde (CH₂O)
- Method
- Emission test chamber method
- Setting
- test chamber, PT
- Study design
- emission chamber study of twelve incense products sold in Portugal: volatile organic compounds, very volatile organic compounds and aldehydes sampled from the chamber by gas chromatography with mass spectrometry and by high performance liquid chromatography, converted through the specific emission rate into a short-term peak concentration and a worst-case time-weighted average for a room of 30 m3, and compared with air quality guideline values (class 4)
- Effect
- share-above 0 per 100 μg/m3
- Sample
- 12 samples
- Caveat
- the study itself says the comparison should use the short-term peak concentration, because the guideline is set for thirty minutes of exposure, and on that reading ten of the twelve products are above it - a sibling row carries that count
