“…FMOC-OH by product make it difficult in separation by chromatography, which is represented by the large peak in front of the glyphosate chromatogram. The FMOC-OH product completely overlaps the glyphosate peak and creates difficulties in its detection (Tadeo et al, 2000). The removal of this FMOC product and separation of the glyphosate peak by column-switching technique using coupled C18 and amino columns was previously reported.…”

“…Chemical agents, that is herbicides, are used widely in the world in protecting crops from undue competition from weeds. The main chemical classes of herbicides (Tadeo et al, 2000) include bipiridilium compounds, triazine derivatives containing three heterocyclic nitrogen atoms in the ring structure (atrazine, prometryn, propazin, etc. ), chlorophenoxy acid derivatives (2, 4-D, 2, 4, 5-T), substituted chloro-acetanilides (alachlor, propachlor), derivatives of 2, 6-dinitroaniline (benfluralin, trifluralin), substituted phenylcarbamates (carbetamide, chlorbufam), urea derivatives (chlorbromuron, chlorotoluron), substituted sulphonylureas (amidosulfuron, trifusulfuron), etc.…”

“…Various techniques have been described, such as chromatography and spectrophotometry. [2][3][4][5] Currently, chromatography (either gas or liquid chromatography) is used in most methods for the determination of herbicide in water. However, some of these methods are time-consuming, particularly those are not suitable for on-site analysis.…”

“…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. The present contribution is an overview of the application of the multiresidue methods of extraction by SFE and analysis by SFC in the analysis of pyrethroid, herbicide, fungicide, and carbamate residues [19,20,21,22] in canned foods, fruits, juices, and frozen vegetables.…”

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.
