Extraneous Maximum Residue Limit (EMRL)
"EMRL" refers to pesticide residues or pollutants originating from environmental sources (including previous agricultural uses) other than the use of pesticides or pollutants directly or indirectly in the product.
Concentration is expressed in milligrams of pesticide residues or pollutants per kilogram of product. You can also get more information about pesticide residue limits codex at https://www.bryantchristie.com/BCGlobal-Subscriptions/Pesticide-MR.
Good agricultural practices in the use of pesticides (CAP)
"GAP" includes the use of safe and nationally approved pesticides under the actual conditions needed for effective and reliable pest control. This includes various levels of application of pesticides to the maximum use that is permitted and implemented to leave the lowest possible residue.

Safe use approval is defined at the national level and takes consideration for public safety, health, and the safety of the environment. Actual conditions cover all phases of production, storage, transportation, distribution, and processing of food and feed.
The limit of quantification
"Quantification limit" means the lowest concentration of pesticide residues or pollutants that can be identified and quantified in certain foods, agricultural products or feed with a certain degree of certainty that can be accepted by the regulatory analysis method.
Maximum residual limit (MRL)
"Maximum residual level" is the maximum concentration of pesticide residues (expressed in mg/kg) recommended by the Codex Alimentarius Code to be legally approved by the Commission in or in food and feed. MRL is based on GAP data, and food originating from goods that meet the relevant MRL must be toxicologically acceptable.
