RESIDUE AND ANALYTICAL ASPECTS
The carbamate insecticide propoxur was first evaluated by the 1973 JMPR. Its residue and analytical aspects were reviewed in 1977, 1981, 1983 and 1991.
At the 1994 CCPR several delegations expressed the opinion that the MRLs recommended by the 1991 Meeting for head lettuce and potatoes were based on very old data.
The Meeting received data from supervised trials on lettuce and potatoes, information on analytical methods, and monitoring data.
The data from supervised trials were reviewed and MRLs were recommended for lettuce and potatoes, but the Meeting decided not to estimate STMR levels until the compound is evaluated in the CCPR periodic review programme since CXLs have already been established for many other commodities and metabolic studies were not available.
