Strategies for setting occupational exposure limits for particles.
Environmental Health Perspectives, 1997 To set occupational exposure limits (OELs) for aerosol particles, dusts, or chemicals, one has to evaluate whether mechanistic considerations permit identification of a no observed effect level (NOEL). In the case of carcinogenic effects, this can be assumed if no genotoxicity is involved, and exposure is considered safe if it does not exceed the NOEL.

A Review of Wood Dust Longitudinal Health Studies: Implications for an Occupational Limit Value
Dose-Response, 2019 Numerous studies reporting on the health effects of wood dust have been published over many decades. For the clear majority of these studies, their use for setting a science-based occupational exposure level is problematic due generally to insufficient ...
