Acute Toxicities of Organic Chemicals to Fathead Minnows (Pimephales promelas) Volume II

Abstract

The contents of the second volume of Acute Toxicities of Organic Chemicals to Fathead Minnows (Pimephales promelas} provide additional infor­mation for the ongoing development of an aquatic toxicology data base. Listed herein are the methods and results from 151 acute toxicity tests con­ ducted with the fathead minnow (Pimephales promelas} in Lake Superior water. Some chemical classes included in Volume 1 have. been expanded in this volume, with the data lending further support to quantitative structure­ activity relationship CQSAR) model development. Test compounds have been added from several chemical classes not in Volume 1. Behavioral observations have been enhanced through the use of a coded, systemized checklist. These behavioral observations in conjunction with the 96 hr toxicity data, have added to the understanding of a prediction model for narcotic chemicals (Veith et tl·, 1983). Future volumes of Acute Toxicities of Organic Chemicals to Fathead Minnows (Pimephales promelas) will emphasize test results from non-narcotic chemi.ca1 s..
