SUMMARY
The phrase "too slow to be biologically significant" refers to reactions that occur at a probability so low that their impact on biological systems is negligible. In the context of the auto-oxidation of nitric oxide (NO) to form nitrogen dioxide (NO2), this indicates that while the reaction does occur, its rate is insufficient to affect biological processes meaningfully. The National Research Council's guidelines specify a 24-hour exposure limit of 0.04 ppm for NO2, emphasizing the importance of dosage in assessing toxicity.
