Aquatic Pollutant Hazard Assessments and Development of a Hazard Prediction Technology by Quantitative Structure-Activity Relationships (Year 1) 24 May 1981 - 23 May 1982

Abstract

Acute toxicity tests. with 18 structure-activity chemicals and fathead minnows (Pimephales promelas) as test organisms were completed during the quarter. Tests with o-nitrobenzaldehyde, 2-decanone, and diethyl adipate were rep ated for a check on reproducioility of r sults. Analytical methods for 5 additional chemicals were developed during the quarter.
