According to Decree 280-2024 published on February 28, 2024, in the Gazette officielle du Québec, the amendment to the Appendix 1 of the Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13) will come into force on March 14, 2024. 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 280-2024 is partially inaccurate or incomplete. Please consult our infoLABO (in French only) for more details. Please contact our client service: [email protected] for further information.

Analysis:

Benzo(b+j+k)fluoranthène

Method: IRSST - 225-2

Sampling protocol

Sampling device:
Sampling media required:
#IRSSTDescription
2187 Orbo 42L tube 100/50 mg

Parameters:
Flow rate: 2 L/min
TWA sampling volume: 960 L
STEL sampling volume: -
Remarks: The sampling train consists of a cassette that will collect the PAHs in particulate form, followed by the sampling tube that will adsorb the PAHs in vapour form. This tube is connected directly to the pump by Tygon tubing. After sampling, the samples must be stored in the freezer protected from light. The tubes and filters must be shipped together and identified to match respectively. 21 PAHs are determined simultaneously. See the info-labos 2008-14 and 2014-02.

Principle: Gas chromatography with mass spectrometry (GC-MS)
Minimum reported value: 0,3 µg
Remarks: On the certificate of analysis, the benzofluoranthene's isomer concentration is expressed as benzo(b+j+k)fluoranthene. Thus, the result includes all benzofluoranthene isomers since they cannot be adequately separated by our chromatographic method. CVa for cassette and tube analysis are respectively 3.4% and 1.2%.
