What thought to mean «Risk characterization»?
A) Determining the concentration of a contaminating agent in the environment and
estimating its rate of intake in target organisms; for example, finding the concentration of
aflatoxin (a fungal toxin) in peanut butter and determining the dose an ‘‘average’’ person
would receive.
B) Estimating the potential impact of a hazard based on the severity of its effects and the
amount of exposure
C) Quantitating the adverse effects arising from exposure to a hazardous agent based on
the degree of exposure. This assessment is usually expressed mathematically as a plot
showing a response (i.e., mortality) in living organisms to increasing doses of the agent
D) Performing cost/benefit analyses of contaminated-site cleanup or treatment options
(including treatment processes to reduce exposure to pathogens)
E) Defining the hazard and nature of the harm; for example, identifying a chemical
contaminant, such as lead or carbon tetrachloride, and documenting its toxic effects on
human beings
