Methodenlisting
Auswertung (Statistische Methode) To estimate the median lethal concentration (LC50) we used a computerized program developed at SRI and composed of several statistical methods for estimating LC50s and EC50s. For this project, we chose' estimates derived only from the log-probit or binomial methods. The specific method we chose depended on the number and pattern of partial responses , (i.e., >0 percent, <100 percent). Organismus Herkunft SRI's breeding colonies Testsystem, Multispezies "Methods for Acute Toxicity Tests with Fish, Macroinvertebrates, and Amphibians" (EPA, 1975) was used as a guide in conducting the tests with the animal species
