ACUTE AND SUBCHRONIC TOXICITY OF SEVERAL PHENOLIC UNCOUPLERS OF OXIDATIVE PHOSPHORYLATION IN FATHEAD MINNOWS (PIMEPHALES PROMELAS)
(1983)Acute and early life stage_ (ELS) toxicity tests were conducted with fathead minnows (Pimephales promela$) and seven chemicals: 2,4-dinitrophenol (2,4-DNP), 4,6-dinitro-o- cresol (DNOC), 2-sec -butyl--4,6-dinitrophenol ... -
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
(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, ... -
EFFECT OF PH ON THE ACUTE TOXICITY OF 2,4,5-TRICHLOROPHENOL TO THE FATHEAD MINNOWS
(1993-04)Acute 96-h flow-through toxicity tests with the compound 2,4,5- trichlorophenol were conducted using 28-d old fathead minnows, Pimephales promelas Rafinesque. Toxicity tests were conducted at six nominal pH levels of ... -
The Effects of Feeding and Not Feeding, Aging and Not Aging Test Solutions on the Toxicity of silver to Fathead Minnows Pimephales promelas
(1993-06-15)Simultaneous.96-h static acute toxicity tests were conducted exposing fathead minnows (Pimephales promelas Rafinesque) to aged and non-aged silver test· solutions. Toxicity tests consisted of exposing test organisms to ... -
Fathead minnow early life-stage toxicity tests wtih dinoseb and caroburan
(1987-07-06)We have completed fathead minnow early life-stage toxicity tests on the University campus with dinoseb and carbofuran. These were flow-through tests with measured concentrations of toxicants. -

(1987-08-31)The Center for Lake Superior Environmental Studies of the University of Wisconsin-Superior, Superior, Wisconsin 54880 has completed acute toxicity test with eighteen organic compounds. Fathead minnows, Pimephales promelas, ... -
Mexel 432 Toxicity to Cladoceran And Fathead Minnow During Continuous or Daily Intermittent Exposures
(1997-05)In many countries, numerous process and chemical products or fo1IDulatjons are used to control fouling organisms development in industrial water cooling circuits_ But, most of these processes are in opposition with ... -
NONYLPHENOL ANALYSIS
(1994-05-31)A study was undertaken in an earlier work assignment (No.1-12) in this contract to expose two species of fish in both short-term acute exposures and longer-term chronic exposures to nonylphenol. The following tests were ... -
NONYLPHENOL TOXICITY (No. 2-15)
(1994-05-31)During this work assignment (No. 2-15), tissue accumulations were measured in all fish stored in iso-octane from the short-term acute exposures. Since the unanalyzed fish have been stored in the freezer for six months, ... -
