Use of Combined Uncertainty of Pesticide Residue Results for Testing Compliance with Maximum Residue Limits (MRLs)
JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 63(18), 4418–4428.
author keywords: sampling; uncertainty of measurement results; compliance with legal limits; pesticide residues; self-control of production; certification of compliance
MeSH headings : Crops, Agricultural / chemistry; Crops, Agricultural / economics; Food Contamination / analysis; Food Contamination / economics; Food Contamination / legislation & jurisprudence; Pesticide Residues / analysis; Pesticide Residues / standards
