The means by which the toxicity of a chemical or other test material is determined. A toxicity test is used to measure the degree of response produced by exposure to a specific level of stimulus (such as concentration of chemical) compared with a unexposed control.
A controlled test in which the effects of a toxicant are studied on living cells, tissues, or organisms.
The means by which the toxicity of a chemical to an organism (target or other) is determined. It measures the degree of response to a specific dose from acute (see LD50) or chronic (see LC50) exposure.
the means to determine the toxicity of a chemical or an effluent using living organisms. A toxicity test measures the degree of response of an exposed test organism to a specified chemical or effluent.
A procedure to determine the toxicity of a chemical or an effluent using living organisms. A toxicity test measures the degree of effect of a specific chemical or effluent on exposed test organisms (EPA, 2000).
A procedure to determine the toxicity of a chemical or an effluent by using living organisms. A toxicity test measures the degree of effect on exposed test organisms of a specific chemical or effluent (USEPA Region 5).
Experimental study of the adverse effects of exposure of a living organism to a substance for a defined duration under defined conditions RT acute toxicity test, carcinogenicity test, chronic toxicity test, subchronic toxicity test
A measure of the toxicity of a chemical or an effluent using living organisms by determining the degree of response (survival, reproduction, growth, etc.) of an exposed organism to the chemical or effluent.
