“…However, it is well known that ECD has been the most used detector in pesticide residues analysis due to its high sensitivity, in particular to halogenated pesticides although all kinds of electron-attracting functional groups such as nitro groups and aromatic structures also give a response on this detector [12,13,18]. Figure 1 shows a chromatogram of insecticide standards analyzed by our GC-ECD system.…”

“…This chromatogram also exhibits other peaks (not identified), and one can notice the complexity of the fruit components. Therefore, the interpretation of ECD chromatograms obtained for extracts with higher amounts of ECD sensitive matrix compounds (Figure 3) can become a difficult task [12].…”

Pesticides compounds represent an important class of pollutants for food, soil and surface water resources. Thus, a simplified method using gas chromatography was used for determining five insecticide residues in fruit samples produced in Ceará State (Brazil). The insecticides were simultaneously extracted from the fruit samples with a mixture of water-methanol (1 : 1 %v/v) from lipid-containing crops and then reextracted with ethyl acetate. Cleanup by silica gel column chromatography was not necessary. The extracts were analyzed by GC-ECD. Analytical parameters, such as limit of detection (LOD), limit of quantification (LOQ), linearity, precision, and recovery were considered for the orange fruit. A sufficient recovery of 52.1, 57.0, 49.5, and 108.5% for parathion methyl, malathion, chlorpyrifos, and 2,4-dichlorophenol was found. The compounds 2,4-dichlorophenol, malathion, parathion methyl, and chlorpyrifos were found in all the fruit samples analyzed.

“…[4][5][6][7] In agreement with the literature, one of the solvents more indicated for pesticide extraction in fruits and vegetables is ethyl acetate in the presence of anhydrous sodium sulphate or acetone, followed by partition with dichloromethane and petroleum ether. 4,8,9 This paper describes the development and validation of a methodology applying extraction with solvent and analysis by GC-NPD for the determination of residues of organophosphorus pesticides used routinely in tomato cultivation. Another propose of the present study was to determine the influence of the matrix in the chromatographic response of organophosphorus pesticides.…”

Os pesticidas organofosforados são freqüentemente aplicados no cultivo de tomate no Brasil. No presente trabalho uma metodologia analítica foi desenvolvida e validada para a quantificação de resíduos dos pesticidas organofosforados acefato, chlorpyrifós, malation, metamidofós and paration metílico em tomate, empregando Cromatografia Gasosa com Detector de Nitrogênio e Fósforo (GC-NPD). A possibilidade de ocorrência de efeito matriz foi estudada. As curvas analíticas, preparadas nos extratos da matriz, foram lineares de 0,006 até 0,80 mg L -1 . Os estudos de precisão forneceram resultados com RSD <15%. As recuperações dos pesticidas, obtidas com as curvas preparadas no extrato da matriz, foram entre 88 e 118%. Com o procedimento proposto foram obtidos limites de quantificação entre 0,0132 e 0,135 mg kg -1 .The organophosphorus pesticides are frequently applied in tomato cultivation in Brazil. In the present work an analytical methodology for quantification of the organophosphorus pesticides: acephate, chlorpyrifos, malathion, methamidophos and parathion-methyl residues in tomatoes was developed and validated using Gas Chromatography with a Nitrogen-Phosphorus Detector (GC-NPD). The possibility of a matrix effect was studied. Analytical curves prepared in an extract of the matrix were linear from 0.006 to 0.80 mg L -1 . The precision studies supplied results with RSD <15%. The recoveries of the pesticides calculated from the curve prepared in the matrix extract were between 88 and 118%. With the proposed procedure quantification limits between 0.0132 and 0.135 mg kg -1 were obtained.

“…In these areas, fruits and vegetables are very important, and therefore acaricides, insecticides, fungicides, and herbicides are applied on the agriculture areas [6,7]. Many different types of pesticides [8,9] are used extensively, leading to the contamination of pesticide residues in fruits and vegetables. Pyrethroid [10], herbicide [11], fungicide [12,13,14], and carbamate [15,16,17,18] residues are frequently detected in fruit and vegetable crops.…”

Multiple pesticide residues have been observed in some samples of canned foods, frozen vegetables, and fruit jam, which put the health of the consumers at risk of adverse effects. It is quite apparent that such a state of affairs calls for the need of more accurate, cost-effective, and rapid analytical techniques capable of detecting the minimum concentrations of the multiple pesticide residues. The aims of this paper were first, to determine the effectiveness of the use of Supercritical Fluid Extraction (SFE) and Supercritical Fluid Chromatography (SFC) techniques in the analysis of the levels of pesticide residues in canned foods, vegetables, and fruits; and second, to contribute to the promotion of consumer safety by excluding pesticide residue contamination from markets. Fifteen different types of imported canned and frozen fruits and vegetables samples obtained from the Houston local food markets were investigated. The major types of pesticides tested were pyrethroids, herbicides, fungicides, and carbamates. By using these techniques, the overall data showed 60.82% of the food samples had no detection of any pesticide residues under this investigation. On the other hand, 39.15% different food samples were contaminated by four different pyrethroid residues ± RSD% ranging from 0.03 ± 0.005 to 0.05 ± 0.03 ppm, of which most of the pyrethroid residues were detected in frozen vegetables and strawberry jam. Herbicide residues in test samples ranged from 0.03 ± 0.005 to 0.8 ± 0.01 ppm. Five different fungicides, ranging from 0.05 ± 0.02 to 0.8 ± 0.1 ppm, were found in five different frozen vegetable samples. Carbamate residues were not detected in 60% of investigated food samples. It was concluded that SFE and SFC techniques were accurate, reliable, less time consuming, and cost effective in the analysis of imported canned foods, fruits, and vegetables and are recommended for the monitoring of pesticide contaminations.
