Finding F-1659
“Out of the sixty salons sampled, 36 salons had formaldehyde levels above the WHO permissible limit of 100 μg/m3 for an eight-hour working period and also exceeded the 55 and 9 μg/m3 for chronic and acute reference exposure limit, respectively, set by the Office of Environmental Health Hazard Assessment.”
Structure
- Factor
- Formaldehyde (CH₂O)
- Setting
- beauty salon
- Study design
- cross-sectional survey of hair and beauty salons: formaldehyde measured in the salon air with an air sampler and analysed spectrophotometrically, then compared against the occupational and reference exposure limits (class 4)
- Effect
- share-above 36
- Caveat
- a count of salons and not a share, out of sixty sampled; the study says these salons also exceeded the chronic and acute reference exposure limits of 55 and 9 µg/m3
