ppm↔ng/ug 1 ng/ug = 1000 ppm.

The peak CO level for employees engaged in roll-on roll-off operations during cargo loading and unloading is 200 ppm. And the EPA has set two national health protection standards for CO: a one-hour TWA of 35 PPM, and an eight-hour TWA of 9 PPM. These standards make it clear that any carbon monoxide reading over 9 PPM should be investigated and acted upon.
