Abstract The level of protection to workers provided by the current threshold value for exposure to beryllium (Be) and its compounds has been challenged over the last few years. Recent cases of workers sensitized to these substances or with chronic beryllium disease indicate that this value may not be suitable for all chemical forms of this metal. The aim of this study was to characterize and identify the main chemical forms of Be sampled in the workplace. Six samples from four different industrial establishments were analysed. The results show that the majority of Be particles have a diameter of less than 10 microns and belong to a wide variety of chemical compounds. This research is part of an ongoing programme to determine the toxicity of beryllium toxicity and to review exposure limits.
