Industry:Biology; Chemistry
Consequence of application of a substance to the surface of the body which occurs at the point of application.
Industry:Biology; Chemistry
Consequence that is either of a generalized nature or that occurs at a site distant from the point of entry of a substance.
Note: A systemic effect requires absorption and distribution of the substance in the body.
Industry:Biology; Chemistry
Contaminant remaining in an organism or in other material such as food or packaging, following exposure.
Industry:Biology; Chemistry
Continual noise in the ears, such as ringing, buzzing, roaring, or clicking.
Industry:Biology; Chemistry
Contribution of a specified component (or components) to the toxicity of a mixture of related substances.
Note 1: The amount-of-substance (or substance) concentration of total toxicity equivalent is the sum of that for the components B, C … N.
Note 2: Toxicity equivalent is most commonly used in relation to the reference toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-tetrachlorooxanthrene) by means of the toxicity equivalency factor (TEF, f) which is 1 for the reference substance. Hence, where c is the amount-of-substance concentration.
Industry:Biology; Chemistry
Death rate computed for a subpopulation of individual organisms or people having a specified characteristic or attribute, and named accordingly.
Example: age-specific death rate, the number of deaths of persons of a specified age during a given period of time, divided by the total number of persons of that age in the population during that time.
