“…These pesticides were dichlorvos, dieldrin, hexaconazole, profenofos, and propargite. A possible reason for these high RSDs may be interfering compounds, which co-elute with the analytes [9,11,12].…”

Animal feed is typically plant-based and can contain pesticide residues. Methods for testing food and feed samples, such as the Quick Easy Cheap Effective Rugged Safe (QuEChERS) method or the Swedish Ethyl Acetate (SweEt) method, successfully extract many pesticide residues. However, nonpolar pesticides, such as organochlorine pesticides, show poor recovery when extracted from lipid-rich samples. The previously developed water-acetonitrile-heptane-solid-phase-extraction (WAHSPE) method shows better recoveries for the nonpolar pesticides but requires two injections per sample and per instrument. Here, we present a modified version of the WAHSPE method for pesticides in fish feed using one injection per sample and per instrument. Of the 184 pesticides tested, 179 met the European Union Legislation’s validation criteria at a spike level of 50 μg/kg, showing recoveries between 70 and 120% and a relative standard deviation (RSD) below 20%. Organochlorine pesticides accounted for 14 of the tested compounds.

We often encounter difficulties in analyzing pesticide residues in food, since the residue level to be measured is infinitesimal but the food samples may contain a variety of matrices, including interferences, for chromatographic analysis. Thus it is important to find out the key points to be checked in the extraction, purification, and determination steps of analysis. We have attempted to develop practical technologies for the analysis of pesticide residues in raw agricultural commodities based on the following studies: The effect of processing and cooking on pesticide residue levels in several crop samples (rice, wheat, soybean, and sesame) was investigated. The processing factor is useful to estimate the amount of exposure to each pesticide residue for risk assessment and is helpful in setting the maximum residue limits of processed foods. In addition, residue levels in the peel and pulp of watermelon, melon, and kiwi fruit samples were examined to confirm the differences in the distribution of residues. As a basic study, the effect of watersoaking pretreatment of powdered dry cereal on extraction efficiency was examined, and an optimal time for water-soaking was found. A recent study examined the ability of several new types of solid-phase extraction columns to remove matrices in brown rice samples and verified the effective purification method for each sample.

“…Carbon fibers coated with different stationary phases, which can be liquid (polymer) or solid (sorbent), can be used to extract different types of analyte. The approach and details of these newly synthesized carbon fibers (E-HyCu) have not been clarified due to a pending patent application by Sugitate and Saka [ 89 ]. However, carbon fibers play the role of two adsorbents: one with hydrophobic (C18) and the other with hydrophilic (carbon/NH 2 ) groups.…”
