Toxicity Value Acronyms and Sources

Toxicity Value Descriptions

1The toxicity values reported above are defined as the concentration of a chemical (or mixture of chemicals) that is likely to pose little or no risk to human health.

2Acute toxicity values are compared to 2nd high 24 hour air concentrations multiplied by 10 (to estimate hourly maximum)

3Chronic toxicity values are compared to 95% upper confidence limit of the arithmetic mean (to be 95% confident that the mean is not underestimated)

410% of total chromium is assumed to be hexavalent chromium (the carcinogenic form of chromium)
