Comparative determination of multi-pesticide residues in Pimpinella anisum using two different AOAC methods

Chlorinated hydrocarbons, pyrethroids, organophosphorus, and other miscellaneous pesticides in dried and powdered fruits of Pimpinella anisum were analyzed using two official Association of Official Analytical Chemists methods as a general guidance, and applying Florisil column cleanup. Both methods...

Description
Summary:Chlorinated hydrocarbons, pyrethroids, organophosphorus, and other miscellaneous pesticides in dried and powdered fruits of Pimpinella anisum were analyzed using two official Association of Official Analytical Chemists methods as a general guidance, and applying Florisil column cleanup. Both methods applied proved to show adequate recovery, repeatability and reproducibility for most of the studied pesticides. But no sole method was able to extract all pesticides residues from real samples. Some pesticides were not recovered sufficiently from the P. anisum fortified samples. The applied methods were not suitable for the extraction of tetramethrin, formothion, pyrazophos and primicarb. Tetramethrin, formothion and pyrazophos showed very low recoveries with the mentioned methods while primicarb was not recovered at all.
