To document the presence of beryllium and worker exposure to this metal, professionals in the health network use the IRSST laboratories’ services. However, current analytical techniques do not detect all forms of beryllium (Be). The aim of this project is to provide the IRSST’s laboratories with a method to evaluate Be concentrations in the air and on workplace surfaces, and whose selectivity will be studied to prevent potential interference. As part of the thematic program on the monitoring and control of worker exposure to beryllium, this study will provide the laboratories with a specific analytical process that, since it is more economical and rapid than the conventional method, will reduce analytical times and costs. This new method will help in preventing worker exposure to beryllium and therefore in reducing workers’ risks of contracting occupational diseases.
