“…Moreover, the analytical method developed was linked with other gas (GC) and liquid chromatography (LC) methods reported in the literature for pesticide quantification in vegetables, Table 4 [1,3,5,8,12,16,[31][32][33][34][35]. The sample amount (g), LOD, LOQ and recovery (analytical performance) were considered to demonstrate the advantages of the QuEChERS-dSPE/UHPLC-PDA method here validated.…”

Insecticides are broadly applied in agriculture to defend crops from illnesses and pest attacks, consequently guaranteeing high production. However, their residual deposits in food products are becoming a main concern with regard to human consumption. As such, sensitive analytical methods should be developed to assess, prevent and control insecticide residues. In this research, an accurate, fast and reliable residual analytical method, that is quick, easy, cheap, effective, rugged and safe, combined with dispersive solid phase extraction (QuEChERS-dSPE), was developed for the determination of the most common insecticides used in potatoes cultivation (chlorpyrifos, λ-cyhalothrin, deltamethrin and acrinathrin), using an ultra-high performance chromatography photodiode array detector (UHPLC-PDA). The most influential extraction and instrumentation parameters that affect the method’s performance, such as extraction solvent, ratio salts, sorbents, stationary phases, gradient conditions and eluents, were assessed. Under the ideal conditions, good linearity (0.992–0.998), limits of detection (0.02–0.47 µg/kg) and quantification (0.06–1.58 µg/kg), recovery (94.1 to 112%) and precision (relative standard deviation <18%) were achieved for spiked levels between 2.5 and 50 µg/kg. The obtained results revealed that the potatoes analyzed do not represent any concern for human healthy, as the insecticide residues detected were lower than the maximum residue limits set by the European Union, Codex Alimentarius, and other organizations.

Nowadays agriculture represents most important economic activity. Agricultural pesticides that are deliberately used to escalate crop yield unfortunately are endowed with many latent and insidious adverse effects. Pesticides and poly-aromatic hydrocarbons are identified worldwide as toxic environmental pollutants that persist in the environment and bioaccumulates in the food chain. This study was thus designed for the analysis of pesticide residues and Polyaromatic hydrocarbons in fruits and vegetables, water and soil. This work was done with the objective to develop an analytical method for selectively and sensitively detecting pesticides and polyaromatic hydrocarbons in different environmental matrices. For this purpose samples of selected fruits, vegetables, soil and water collected from agricultural land were analyzed to determine the residues of selected organochlorine pesticides (Bifenthrin, Imidacloprid, Difenoconazole) and polycyclic aromatic hydrocarbons (Anthracene , Phenanthrene) by High Pressure Liquid Chromatography. The selected method beautifully allowed the qualitative and quantitative determination of Pesticides and Polyaromatic hydrocarbons in selected samples. Results of study revealed the presence of Anthracene in a concentration ranges from 0.0655-31.632mg/kg, Difenoconazole in concentration ranges from 0.03-18.604mg/kg and Bifenthrin in concentration ranges from 0.024-11.74 mg/kg in different study samples which were exceeding maximum residue limits (MRL) set by Codex Alimentarius Commission.

“…The results ( Fig. 2A) indicated that when silica gel, C 18 and Florisil were used, the extraction recovery of four amides were higher than the extraction recovery with Al 2 O 3 . Therefore, silica gel was selected as the dispersing sorbent, for its cheap and widely used.…”

A rapid and simple analytical method was established for the determination of four amides (N-p-trans-coumaroyltyramine, aristolactam AⅡ, sauristolactam and aristolactam BⅡ) in Saururus chinensis by matrix solid phase dispersion (MSPD) and high-performance liquid chromatography-diode array detector (HPLC-DAD). In the optimized MSPD, 0.2 g S. chinensis powder was blended with 0.4 g silica gel, and 5 mL methanol was selected as elution solvent. The MSPD extraction achieved higher extraction recovery of four amides, and required less sample, solvent and preparation time, comparing with the conventional methods (Soxhlet and ultrasonic extraction). The assay was performed on a TSK gel ODS-100Z column (4.6 mm × 250 mm, 5 μm) at 30 °C. Acetonitrile and 0.4% acetic acid aqueous solution was used as mobile phase by gradient elution at the flow rate of 1.0 mL/min. The detection wavelength was 280 nm. All the analytes showed good linear regression (R ≥ 0.9998) within the concentration ranges. The validated method showed good precision and stability with relative standard deviations (RSDs) ≤ 3.18%. The recoveries were in the range of 96.57-99.65%, with RSDs less than 2.74%.
