Red Cliff Fish Consumption
(1992-02-12)
We are pleased to submit this six month report to the Great Lakes Protection Fund. Overall we have made good progress and although some portions are more difficult than we originally anticipated, we believe the study is ...
THE EFFECTS OF WATER HARDNESS, Ph, CHLORIDE AND SULFATE SALTS, AND DISSOLVED ORGANIC MATTER ON THE TOXICITY OF SILVER TO FATHEAD MINNOWS (PIMEPHALES PROMELAS)
(1992-05-02)
A relationship between water hardness and the toxicity of silver to aquatic organisms was reported
in the National Water Quality Criteria for th Protection of Aquatic Life for Silver document (EPA
440/5-80-071 or PB81- ...
pH Dependency of 2,4,5-Trichlorosphenol Toxicity
(1993-09-30)
Acute 96-h flow-through toxicity tests with the compound 2,4,5- trichlorophenol (TCP) were
conducted using the annelid, Lumbriculus variegatus, as the test organism. Toxicity tests were
conducted at three nominal pH ...
The Chironomus tentans Survival and Growth Bioassay: A Study of the Effect of Reduced Larval Growth Upon the Following Generation and an Application of the Bioassay in Evaluating Sediment Quality
(1993-09)
A life-cycle study was conducted with Chironomus tentans to assess the significance
of growth retardation of second to third instar larvae over a 10-d test period on long-term
survival, emergence success, and fecundity. ...
SEDIMENT QUALITY EVALUATION IN THE LOWER FOX RIVER AND SOUTHERN GREEN BAY OF LAKE MICHIGAN
(1991-04)
The quality of sediment from the Lower Fox River between the dam at DePere, Wisconsin, and the
mouth of the river, and from the southern tip of Green Bay, Lake Michigan, was evaluated at 12
sites by a combination of ...
Toxicity of Silver to the Fathead Minnow and an Invertebrate in Aged Toxicant Solutions with Laboratory Water and St. Louis River Water
(1993-10-10)
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 Effects of Food and Test Solution Age on the Toxicity of Silver to Three Freshwater Organisms
(1993-09)
Acute toxicity tests were conducted to determine the effects on the toxicity of silver of having
food present in test chambers and the effect of having silver solutions of different ages. Tests
were conducted in two ...
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 ...
The Effects of Feeding and Not Feeding, Aging and Not Aging Test Solutions on the Toxicity of Silver to Daphnia magna
(1993-06-21)
Simultaneous 48-h static acute toxicity tests were conducted exposing the cladoceran, Daphnia
magna, to silver solutions with four test conditions. The tests consisted of exposing test
organisms to aged test solutions ...
