| 词条 | Hazard quotient |
| 释义 |
A hazard quotient is the ratio of the potential exposure to a substance and the level at which no adverse effects are expected. If the Hazard Quotient is calculated to be less than 1, then no adverse health effects are expected as a result of exposure. If the Hazard Quotient is greater than 1, then adverse health effects are possible. The Hazard Quotient cannot be translated to a probability that adverse health effects will occur, and is unlikely to be proportional to risk. It is especially important to note that a Hazard Quotient exceeding 1 does not necessarily mean that adverse effects will occur.[1] References1. ^{{cite web|url= http://www3.epa.gov/airtoxics/natamain/gloss1.html|title=NATA Glossary of Key Terms|accessdate=2015-12-03}} This article is based on material from the public domain U.S. Federal Government document "NATA Glossary of Terms"{{environment-stub}} 1 : Pollution |
