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:
“When a man leaves his mistress, he runs the risk of being betrayed two or three times daily.”
—Stendhal [Marie Henri Beyle] (1783–1842)
“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)
“I leave the governor’s office next week, and with it public life ... [which] has been on the whole a pleasant one. But for ten years and over my salaries have not equalled my expenses, and there has been a feeling of responsibility, a lack of independence, and a necessary neglect of my family and personal interests and comfort, which make the prospect of a change comfortable to think of.”
—Rutherford Birchard Hayes (1822–1893)
“I am astonished at the singular pertinacity and endurance of our lives. The miracle is, that what is is, when it is so difficult, if not impossible, for anything else to be; that we walk on in our particular paths so far, before we fall on death and fate, merely because we must walk in some path; that every man can get a living, and so few can do anything more. So much only can I accomplish ere health and strength are gone, and yet this suffices.”
—Henry David Thoreau (1817–1862)
