Not all of them. The NAAQS for CO and several other air pollutants are 8 hour standards. I use them for our sets on which children will be working.

One important factor not mentioned is that occupational exposure limits
assume that exposures (typically 8 hours) are interrupted by recovery times,
whereas environmental limits assume 24 hour exposures.

Here's an op-ed that addresses a specific point about government policy and
practice that may be useful when training students on chemical safety
issues, particularly interpretation of various Occupational Exposure Limits.
There's partisan commentary, as might be expected on the NY Times editorial
page, but the key point about OSHA PELs vs. EPA's approach chemical exposure
is an important teaching point.

Why do federal regulators allow employers to expose workers to levels of
toxic chemicals far higher than those considered safe for everyone?
