Occupational Exposure Limits (OELs) are regulatory values that indicate the maximum acceptable concentration of a hazardous substance in workplace air. These limits are set to protect workers from potential health risks associated with exposure to chemicals, dust, fumes, and other hazardous substances. In the context of Nanotechnology, OELs are crucial for ensuring safe working environments, especially since nanoparticles can exhibit unique properties that may pose different health risks compared to their bulk counterparts.
