How can environmental regulators use information on 48-hour toxicity tests to predict the effects of a few minutes of pollution? Or, at the other extreme, what is the relevance of 96-hour toxicity data for organisms that may have been exposed to a pollutant for six months or more? Time to event methods are the key to answering these types of questi

This volume is the first comprehensive treatment of time to event methodology as it relates to ecological risk assessment. Leading Experts from industry, academia, and government regulatory agencies explain how these methods can be used to extract more useful information from laboratory data than can be gained from the use of simple summary statistics. The book offers a clear introduction to the field through several approaches, from the introductory to the more mathematical. It demonstrates the relevance of time in the analysis and reporting of toxicity data by providing practical examples from the field of environmental toxicology. It also incorporates helpful analogies from other disciplines that more commonly use time to event modeling.
