    Pesticide Analysis Methods Pesticide Analysis Methods Florida Department of Agriculture Multi-Residue Method This method is for analyzing residues of all major classes (organophosphate, organochlorine, pyrethroids, carbamates, triazines,etc.) of pesticides on fruits and vegetables. Techniques employed for analysis include; GC-halogen specific. A very large number of pesticides now have public health importance, either because of their use against disease vectors or because, either in use or as residues in foods, they may constitute toxic hazards to man. Accordingly, a highly complex variety of names, specifications and analytical procedures has grown up, with confusing differences due to national by: 6.

The list, given in par.2, is not exhaustive and methods not mentioned in the list can also be applied, provided that they can be shown to be effective. The QuEChERS method was developed to help in the analysis of pesticides — and is now used in other types of analysis. As consumers become more aware of what they are eating — the challenges for pesticide analysis will increase, a topic discussed in the article, Challenges Facing Pesticide Analysis and Monitoring - An Interview with Dr.
