3 Terms and Definitions
The terms and definitions below apply to this standard.
3.1 Residue definition
Residue means any specified substances in food, agricultural commodities, or animal feed resulting
from the use of a pesticide, including any derivatives of a pesticide, such as conversion products,
metabolites, reaction products, and impurities considered to be of toxicological significance.
3.2 Maximum residue limit (MRL)
MRL is the maximum concentration of a pesticide residue (expressed as mg/kg) to be legally
permitted in or on food commodities and agricultural products.
3.3 Acceptable daily intake (ADI)
ADI of a substance is the daily intake which, during an entire lifetime, appears to be without
appreciable risk to the health of the consumer. It is expressed in kilogram of the substance per kilogram
of body weight.
