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 ...

Seven-day acute renewal toxicity_ tests were conducted using the fathead minnow (Pimephales promelas) or a cladoceran (Ceriodaphnia dubia) by exposing them to several concentrations of either ammonia, aniline, methyl ...

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.

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 ...

Simultaneous renewal acute toxicity tests were conducted exposing fathead minnows (Pimephales promelas) to silver at three pH levels. The purpose of the tests was to determine if pH of the water affected the toxicity of ...

Simultaneous renewal 96-h acute toxicity tests were conducted exposing fathead minnows (Pimephales promelas) to silver at three organic carbon levels. The purpose of the tests was to determine £he relationship between the ...

Acute toxicity tests with silver nitrate (AgN03) were conducted with two species of test organisms. The fathead minnow, Pimephales promelas Rafinesque, and a cladoceran, Daphnia magna, were used to determine the effects ...

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, ...
