Introducing an occupational exposure limit (OEL) of 2 μg/m3 for beryllium would: 1) Require further investment from 6-12% of companies handling beryllium alloys to comply; 2) Cost €5-34 billion for compliance measures like improved ventilation; 3) Only prevent about 10 cases of lung cancer per year in the EU according to risk estimates. The high costs of compliance significantly outweighed the small health benefits, so there was no clear case for lowering the OEL for beryllium exposure.
