On March 26, 2020, according to Decree 159-2020 published on March 11, 2020 in the Gazette officielle du Québec, the Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13) is amended in Appendix 1. These regulatory changes have not yet been incorporated into the current Substance Data Sheets of the Sampling Guide for Air Contaminants in the Workplace. An update is currently underway and will be available as soon as possible. Consequently, the information contained in the data sheets of substances modified or added in Decree 159-2020 is probably inaccurate or incomplete.

Flow rate: 0,1 L/min
TWA sampling volume: 10 L
STEL sampling volume: -
Remarks: Before and after sampling, the tubes must be kept in the freezer.
Principle: Gas chromatography with mass spectrometry (GC-MS)
Precision: 9,9
Minimum reported value 0,04 µg
Remarks: Eleven aldehydes are determined simultaneously: acetaldehyde, isobutyraldehyde, isovaleraldehyde, propionaldehyde, butyraldehyde, furfural, heptanal, hexanal, valeraldehyde, acrolein and formaldehyde. This method must not be used for the specific evaluation of formaldehyde; the methods to be used in this case are 295-1 and 357-1.
