The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
Determination of the level, concentration or uptake of a potentially toxic compound and (or) its metabolite(s) in biological samples from an organism (blood, urine, hair etc.) and the interpretation of the results to estimate the absorbed dose or degree of environmental pollution; or the measuring of biochemical effects, usually not direct adverse effects of the substance, and relating them to the quantity of substance absorbed, or to its concentration in the environment.
Industry:Biology; Chemistry
Development and implementation of technologies to characterize the mechanisms through which genes and their products function and interact with each other and with the environment.
Industry:Biology; Chemistry
Device for taking samples of environmental media following diffusional contact with a suitable collecting material.
Industry:Biology; Chemistry
Diameter of a spherical particle of the same density as a particle under investigation that, relative to a given phenomenon or property, would behave in the same way as the particle under investigation.
Industry:Biology; Chemistry
Differential with respect to time of the concentration or amount of a substance in the body, or a part thereof, resulting from elimination.
Industry:Biology; Chemistry
Dilution of a pollutant by spreading in the atmosphere or water due to diffusion or turbulent action.
Industry:Biology; Chemistry
Disappearance of a substance from an organism or a part thereof, by processes of metabolism, secretion, or excretion.
Industry:Biology; Chemistry
Discharge or elimination of an absorbed or endogenous substance, or of a waste product, and (or) its metabolites, through some tissue of the body and its appearance in urine, feces, or other products normally leaving the body.
Note: Excretion does not include the passing of a substance through the intestines without absorption.
Industry:Biology; Chemistry
Disease of the kidneys marked by degeneration of renal tubular epithelium.
Industry:Biology; Chemistry
Distribution function F(y), in which the logarithm of a quantity is normally distributed, i.e.
F(y) = ƒgauss(ln y)
where ƒgauss(χ) is a Gaussian (or normal) distribution.
