Procedures for Establishing MRLs and Setting Up PHI in China

Necessary components for establishment of MRLs in China involve acceptable daily intake (ADI), Chinese national dietary patterns, and residue data generated at GAP. Below is the procedrue for setting MRLs  

1) The highest residue level reported from residue trial studies in target crops following the critical GAP are used to estimate MRL. 

2) Simultaneously, the full toxicology data is evaluated to derive the ADI. The ADIs that have been already proposed by JMPR or other registration authorities should be considered in risk assessment when there is no ADI in Ghina. 

TMDI (Theoretical Maximum Daily Intake) will be calculated as follows TMDI=X[MRLiXFJ 

MRLj = Maximum Residue Limit for a given food commodity Fj = Corresponding national consumption of that food/person/day
