TOXICITY TESTING WITH PHTHALATE ESTERS AND CHIRONOMUS TENTANS TO EVALUATE EQ-P
(1997-08-29)The Lake Superior Research Institute (LSRI) of the University of Wisconsin Superior contracted with the Great Lakes Environmental Center to perform a 10-day sediment toxicity test with di-n-butyl phthalate (DBP)-spiked ... -
TOXICITY, BIOCONCENTRATION AND METABOLISM OF SELECTED CHEMICALS IN AQUATIC ORGANISMS
(1980)PROJECT OBJECTIVES This study will provide information for an assessment of (1) the hazard potential of selected organic compounds for freshwater organisms, and (2) the use of aquatic organisms as biological screening ... -
TOXICITY, BIOCONCENTRATION, AND METABOLISM OF FIVE HERBICIDES IN FRESHWATER FISH
(1985)Acute and early life-stage toxicities were determined for the herbicides alacblor, bromacil, dinoseb, diuron, and propanil with the fathead minnow (Pimephales promelas). Uptake, bioconcentration potential, and elimination ... -
TOXICOLOGICAL STUDIES WITH HERBICIDES, SELECTED EPA PRIORITY POLLUTANTS AND RELATED CHEMICALS IN AQUATIC ORGANISMS
(1982-11)Toxicological studies were conducted in two areas: (1) the toxicity, biocdncentration potential and metabolism of five herbicides in fish; and (2) the toxicity and/or metabolism of priority pollutants and related chemicals ... -

(1982-11)Toxicological studies were conducted in two areas: (l) the toxicity, bioconcentration potential and metabolism of five herbicides in fish; and (2) the toxicity and/or metabolism of priority pollutants and related chemicals ... -
TRANSPORT OF TOXIC SUBSTANCES INTO LAKE SUPERIOR BY SUSPENDED SOLIDS
(1983-10)A primary threat to Great Lakes sport and commercial fisheries arises from contamination problems due to the introduction of certain xenobiotic chemicals in aquatic environments. Of particular concern are hydrophobic ... -
Transport of Toxic substances into Lake Superior by Suspended Solids
(1983-10)A primary threat to Great Lakes sport and commercial fisheries arises from contamination problems due to the introduction of certain xenobiotic chemicals in aquatic environments. Of particular concern are hydrophobic ... -
TRIFLURALIN: ACUTE TOXICITY TO THE MIDGE, CHIRONOMUS TENTANS, UNDER FLOW-THROUGH CONDITIONS
(1991-03-19)The test substance trifluralin, a,a,a-trifluro-2,6-dinitro-N,N-dipropyl-p toluidine, is a yellow-orange crystal that is used commercially as a herbicide. Its solubility in water is less than 1 mg/L (Farm Chemicals ... -
TRIFLURALIN: ACUTE TOXICITY TOE THE MAYFLY, HEXAGENIA LIMBATA, UNDER FLOW-THROUGH CONDITIONS
(1991-03-19)The test substance trifluralin, a,a,a-trifluro-2,6-dinitro-N,N-dipropyl-p-toluidine is a yellow-orange crystal that is used commercially as an herbicide. It is used as a selective preemergence herbicide. Its solubility ... -
VALIDATION OF SEDIMENT QUALITY CRITERIA DRIVED FROM EQUILIBRIUM PARTITIONING THEORY
(1993-01-12)The equilibrium partitioning theory (EPT) approach in conjunction with existing water quality criteria (YQC) has been adopted by EPA for establishing sediment quality criteria (SQC) for nonionic organic chemicals (Di ... -
VALIDATION STUDY OF A PROTOCOL FOR TESTING THE ACUTE TOXICITY OF PESTICIDES TO INVERTEBRATES USING THE APPLE SNAIL
(1993-10)This study evaluated a draft protocol for performing acute toxicity tests with pesticides, using the Florida apple snail, Pomacea paludosa, as a test species. Juvenile snails of 1 and 7 to 8 days of age were used in ... -
VARIATION OF ACUTE TOXICITY WITH WATER SOURCE
(1983)Physical and chemical characteristics of water may affect the biological avail ability and toxicity of chemicals in aquatic environments. Hardness, alkalinity, pH, dissolved organic matter, and suspended materials ... -
VEGETATION AND RED CLAY SOIL STABILITY
(1976)Vegetation cover, and related factors such as litter and organic content of soil, is known to be important in controlling and/or reducing erosion rates (1). Other factors such as slope, soil particle size, soil ... -
