Abstract Toxicity tests results are often condensed into a single endpoint (LC50) to facilitate their use in environmental management. The single number cannot distinguish between two tests with equal LC50s but dissimilar slopes at LC50 and it cannot describe the response at low and high dose levels. Some chemicals produce a flat response at low dose levels, others produce a steep response. The management of different chemicals requires different strategies and a more comprehensive approach to analysis of test data than use of a single endpoint. An alternative analysis of test data using Weibull survivor function produces information on the overall form of the dose-response curve and enables calculation of toxicity, the slope, and errors at arbitrary protection levels, including the conventional 50% level.
