Introduction of GB 2763.1-2018

National Food Safety Standard Maximum Residue Limits for 43 Pesticides in Food (including Paraquat) 1 Scope This standard specifies 302 maximum residue limits for 43 pesticides (including Paraquat) in food. The standard applies to foods related to residue limits . The food categories and testing parts (Appendix A) provided in GB 2763-2016) apply to this standard. If the maximum residue limit of a pesticide is applicable for a certain food category, all the foods in this category will be applicable to this MRL, except otherwise specified. 2 Normative references The following normative documents in this standard are essential for the application of the standard. For dated references, only the dated versions apply to this standard. For not dated references, the latest versions (including all modifications) apply to this standard.

It is expressed in kilogram of the substance per kilogram of body weight. 4 Technical requirements 4.1 Paraquat 4.1.1 Main applications: herbicide 4.1.2 ADI: 0.005 mg/kg bwt. 4.1.3 Residues: paraquat cation, expressed as paraquat dichloride. 4.1.4 MRL: shall meet provisions of Table 1.
