A reference dose is the United States Environmental Protection Agency's maximum acceptable oral dose of a toxic substance. Reference doses are most commonly determined for pesticides. The EPA defines an oral reference dose (abbreviated RfD) as:
n estimate, with uncertainty spanning perhaps an order of magnitude, of a daily oral exposure to the human population (including sensitive subgroups) that is likely to be without an appreciable risk of deleterious effects during a lifetime.

Famous quotes containing the words reference and/or dose:
“If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.”
—William York Tindall (1903–1981)
“Whipping and abuse are like laudanum: you have to double the dose as the sensibilities decline.”
—Harriet Beecher Stowe (1811–1896)
