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- ...
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 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 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 with ...
Toxicity of Silver to Fathead Minnows at Three Values of pH
(1922-04-27)
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 ...
TOXICITY OF SILVER TO FATHEAD MINNOWS AT THREE LEVELS OF ORGANIC CARBON
(1992-05-02)
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 ...
BIOAVAILABILITY AND TOXICITY OF SILVER TO BENTHIC ORGANISMS IN FRESHWATER SYSTEMS CONTAINING SEDIMENTS OF DIFFERENT CHARACTERISTICS - PROGRESS REPORT (Quarters I and II)
(1997-03-31)
Since the proposal for this project was submitted in early August, 1996, and approved by the National Association of Photographic Manufacturers (NAPM) for study starting on October 1, 1997, several changes have been discussed ...
BIOAVAILABILITY AND TOXICITY OF SILVER TO BENTHIC ORGANISMS IN FRESHWATER SYSTEMS CONTAINING SEDIMENTS OF DIFFERENT CHARACTERISTICS - PROGRESS REPORT (Quarter III)
(1997-06-30)
This progress report covers the period of time between April 1, 1997, and June 30, 1997. Our efforts were focused on obtaining a better understanding of (l) the chemical behavior of silver in our specific test water as ...
