Toxicity of Toluene to Several Freshwater Species
Toluene is methylated benzene and obtained mainly from tar oil. It has many common uses as a solvent and in the manufacture of benzoic acid, benzaldehyde, explosives, dyes and many other organic compounds. Toluene behaves ...
TOXICITY OF PHENANTHRENE TO SEVERAL FRESHWATER SPECIES
Phenanthrene is a by-product of fossil fuel combusion. It is a constituent of coal tars and has been detected in the stack gases of both oil- and coal-fired power and manufacturing plants. The purpose of this study ...
CONDUCTING TOXICITY TESTS WITH FRESHWATER ORGANISMS EXPOSED TO DIELDRIN, FLUORANTHENE AND PHENANTHRENE
Several toxicity tests are needed to complete data sets for the numerical national water quality criteria for the protection of aquatic life. This report contains some of the needed tests which are: an acute renewal ...
ACUTE TOXICITY OF ACENAPHTHENE TO DUCKWEED
Acenaphthene is a polycyclic aromatic hydrocarbon (PAH). It is a constituent of coal tar and other petroleum residues. The compound is used as a dye intermediate, as an insecticide and fungicide, and in the manufacture ...
Acute Toxicity of Lead to the Annelid Lumbriculus variegatus and the Amphibian Rana catesbiana
Acute 96-h flow-through, toxicity tests with lead were conducted using the annelid Lumbriculus variegatus and the bullfrog Rana catesbiana as the test organisms. The toxicity tests were-conducted to generate ECSO or ...
EFFECT OF PH ON THE ACUTE TOXICITY OF 2,4,5-TRICHLOROPHENOL TO THE RAINBOW TROUP ONCOHYNCHUS MYKISS
Acute 96-h flow-through toxicity tests with the compound 2,4,S trichlorophenol (TCP) were conducted using rainbow trout Oncorhynchus mykiss as the test organism. Toxicity tests were conducted at three nominal pH ...
Acute Phenanthrene Toxicity to Daphnia magna
A 48-h acute toxicity test was conducted exposing the cladoceran, Daphnia magna, to five concentrations of phenanthrene. Renewal of exposure solutions of phenanthrene was done every 24-h.
