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:
“The risk for a woman who considers her helpless children her “job” is that the children’s growth toward self-sufficiency may be experienced as a refutation of the mother’s indispensability, and she may unconsciously sabotage their growth as a result.”
—Letty Cottin Pogrebin (20th century)
“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 total collapse of the public opinion polls shows that this country is in good health. A country that developed an airtight system of finding out in advance what was in people’s minds would be uninhabitable.”
—E.B. (Elwyn Brooks)
“O how can it be that the ground itself does not sicken?
How can you be alive you growths of spring?
How can you furnish health you blood of herbs, roots, orchards, grain?
Are they not continually putting distemper’d corpses within you?
Is not every continent work’d over and over with sour dead?”
—Walt Whitman (1819–1892)
