A REPORT ON THE ACTIVITIES OF THE CORESTA SUB-GROUP ON PESTICIDE RESIDUES For the period October 1994 - September 1995

Abstract

Updates activities of CORESTA Sub-group on Pesticide Residues in relation to the following analytes: organochlorine, maleic hydrazide (MH-30), organophosphorous, ethylene bis-dithiocarbamate (EBDC) and N-methylcarbamate. Anticipates that "the larger part of Sub-group energy in the coming two years will be devoted to MH-30 studies." Notes that questions raised by the ISO TC 126 Secretariat regarding the CORESTA Recommended Method No. 2 ("Determination of Organochlorine Pesticide residues on Tobacco") have been satisfied. Details complications in utilizing current ISO and AOAC methodologies for analyzing MH-30 residues and notes that "ISO are looking to CORESTA for a replacement of the current 4876 standard method." Characterizes problem as "inconsistent results from standard methods being inconsistently followed." Examines option of using Carbon-14 labeled MH-30. Outlines future plans for rectifying difficulties in MH-30 analysis. States that Sub-group members would examine a "new, rapid method" for analysis of organophosphorous pesticide and that "results of analysis for EBDC residues obtained by particular methods differ." Notes that "whether this is a specific laboratory problem or a general method issue has yet to be determined." Briefly describes current method of N-Methylcarbamate analysis.
