substance
August 29, 2025
Beryllium, inhalable
French name in the regulation:
Béryllium, fraction inhalable
CAS :
7440-41-7
Not in the regulation.
CNESST – Toxicological Index Service
Consult REPTOX file:
Analysis:
Béryllium, fraction inhalable
Method: IRSST - 359
Sampling protocol
Sampling device:
Sampling media required:
#IRSST
Description
928
Plastic IOM, MEC filter, 0.8 µm, 25 mm
Parameters:
Flow rate: 2.0 L/min
TWA sampling volume: 240 L
STEL sampling volume: -
Analytical protocol
Principle:
Inductively coupled plasma spectrometry (ICP-MS)
Precision (%):
2,3
Minimum reported value:
0,0005 µg
Remarks:
Specific sampling must be carried out for this substance. This method allows the analysis of chemical elements present in the sample without distinguishing the different chemical forms. The analytical results are expressed as beryllium, inhalable fraction.
