“…The concentrations of chlorpyrifos residues in vegetables were calculated against the standard curve ( Figure 2) and reported in µg/kg of vegetable sample. The results of the immunoassay were usually validated with the gold standard technique, i.e., a chromatographic technique [34,40,48]. [40,[49][50][51].…”

Chlorpyrifos is an organophosphate pesticide that is wildly used among farmers for crop protection. However, there are concerns regarding its contamination in the environment and food chain. In the present study, an in-house indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) specific for detecting chlorpyrifos is developed and validated against gas chromatography–flame photometric detection (GC-FPD) as the conventional method. The developed ic-ELISA was used for detecting chlorpyrifos residue in vegetable samples. The developed ic-ELISA showed good sensitivity to chlorpyrifos at an IC50 of 0.80 µg/kg, with low cross-reactivity to other organophosphate pesticides. The 160 samples were collected from local markets located in the Chiang Rai, Chiang Mai, and Nan provinces in northern Thailand. The positive rate of chlorpyrifos residues in the vegetable samples was 33.8%, with the highest levels found in cucumbers, coriander, and morning glory, at 275, 145, and 35.3 µg/kg, respectively. The highest median levels of chlorpyrifos found in the detected samples were Chinese cabbage (332 μg/kg), cucumber (146.3 μg/kg) and Chinese Kale (26.95 μg/kg). The developed ic-ELISA is suitable for the rapid quantitation of chlorpyrifos residues.

This article presents an overview of analytical methods for the analysis of pesticide (new‐generation) and related compounds in the last 5 years, which updates the previous one. Pesticides included in this group display almost no change, but the evolution of analytical techniques is important. In general, new pesticides are now included in multiresidue methods with generic sample treatment methodologies being able to extract as many pesticide classes as possible. However, this article focuses not only on these common multiresidue methods but also on specific methodologies as single‐residue methods for the analysis of new‐generation pesticides. The most widely used detection technique for the determination of pesticides is mass spectrometry (MS) combined with gas chromatography (GC) and/or liquid chromatography (LC). However, the advances in immunoassays, biosensors and other techniques are also included. Finally, the future perspectives and the trends for pesticide residue analysis in food and environmental matrices are outlined.
