Acute Toxicities of Organic Chemicals to Fathead Minnows (Pimephales promelas) Volume II
MetadataShow full item record
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..
