Risk Assessment in Public Health
In the context of public health, risk assessment is the process of quantifying the probability of a harmful effect to individuals or populations from certain human activities. In most countries the use of specific chemicals or the operations of specific facilities (e.g. power plants, manufacturing plants) is not allowed unless it can be shown that they do not increase the risk of death or illness above a specific threshold. For example, the American Food and Drug Administration (FDA) regulates food safety through risk assessment. The FDA required in 1973 that cancer-causing compounds must not be present in meat at concentrations that would cause a cancer risk greater than 1 in a million lifetimes. The US Environmental Protection Agency provides basic information about environmental risk assessments for the public via its risk assessment portal.

Famous quotes containing the words risk, assessment, public and/or health:
“Do you want me to tell you something really subversive? Love is everything it’s cracked up to be. That’s why people are so cynical about it.... It really is worth fighting for, being brave for, risking everything for. And the trouble is, if you don’t risk anything, you risk even more.”
—Erica Jong (b. 1942)
“The first year was critical to my assessment of myself as a person. It forced me to realize that, like being married, having children is not an end in itself. You don’t at last arrive at being a parent and suddenly feel satisfied and joyful. It is a constantly reopening adventure.”
—Anonymous Mother. From the Boston Women’s Health Book Collection. Quoted in The Joys of Having a Child, by Bill and Gloria Adler (1993)
“The future of America may or may not bring forth a black President, a woman President, a Jewish President, but it most certainly always will have a suburban President. A President whose senses have been defined by the suburbs, where lakes and public baths mutate into back yards and freeways, where walking means driving, where talking means telephoning, where watching means TV, and where living means real, imitation life.”
—Arthur Kroker (b. 1945)
“I hold it that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms in the physical.... It is a medicine necessary for the sound health of government.”
—Thomas Jefferson (1743–1826)
