Aquatic Pollutant Hazard Assessments and Development of a Hazard Prediction Technology by Quantitative Structure-Activity Relationships (Year 1) 24 May 1981 - 23 May 1982
Call, Daniel J.; Brooke, Larry T.; Ahmad, Nasim; Vaishnav, Dinesh D. (1982)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 ... -
Aquatic Pollutant Hazard Assessments and Development of a Hazard Prediction Technology by Quantitative Structure-Activity Relationships Second Quarterly Report to EPA 24 August 1981 - 23 November 1981
Call, Daniel J.; Brooke, Larry T.; Ahmad, Nasim; Vaishnav, Dinesh (1981)Acute toxicity tests with the fathead minnow (Pimephales promela s) as test organism were completed for five chemicals in the structure-activity program this quarter. These chemicals were dibutyl succinate, ethyl hexanoate, ... -
ESTIMATES OF "NO EFFECT" CONCENTRATIONS OF SELECTED PESTICIDES IN FRESHWATER ORGANISMS (YEAR III) 1 April 1980 - 23 May 1981
