“…In the cultivation of potatoes, insecticides, namely organophosphorus (e.g., chlorpyrifos) and pyrethroids (e.g., λ-cyhalothrin, deltamethrin, acrinathrin), are widely used to protect crops from pest and disease attacks [2][3][4]. In spite of their effectiveness in agricultural application, the imprudent application of insecticides in processing, storage, transport and/or marketing can contribute to their harmfulness, which involves the emission of metabolites and degradation products into the environment (e.g., soil, water, foods) [5,6]. Insecticide presence has been connected to a varied spectrum of human health vulnerabilities, ranging from headaches and nausea, to chronic impacts, endocrine system disruption, reproductive harm, and even cancer.…”

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.

A liquid chromatography with tandem mass spectrometry method was developed and validated to simultaneously determine chlorpyrifos, imidacloprid, and imidacloprid metabolites in soil, wheat grain, and wheat straw matrices. Satisfactory linearity (R2 ≥ 0.9965) of the method was obtained for all analytes. The ranges of limits of detection and limits of quantification for seven analytes in three matrices were 0.17–66.7 and 0.5–200 μg/kg, respectively. Average recoveries were 72.85–81.25% for chlorpyrifos, 78.54–84.70% for imidacloprid, 73.83–81.03% for imidacloprid olefin, 71.47–80.61% for 5‐hydroxy imidacloprid, 71.79–81.32% for imidacloprid urea, 70.42–82.20% for imidacloprid nitroguanidine, and 70.91–82.46% for imidacloprid 6‐chloronicotinic acid in soil, wheat grain, and wheat straw. The intra‐ and interday relative standard deviations were less than 8%. The established method was successfully applied for the residual analysis of chlorpyrifos, imidacloprid, and imidacloprid metabolites in actual soil, wheat grain, and wheat straw samples. The results indicated that the established method could be used to detect trace amounts of chlorpyrifos, imidacloprid, and imidacloprid metabolites in wheat and that the method might be able to provide some data on the detection of these seven compounds in other crops.

A New Approach for the Voltammetric Determination of Amoxicillin in the Dosage Form Using Azo Coupling Reaction with Sulphanilamide

et al. 2021

The novel method of amoxicillin (AM) determination has been developed using single-sweep polarography. The proposed method is based on the obtaining of yellow coloured azo compound due to azo coupling reaction of previous diazotized sulphanilamide (SA) (in the medium of 0.6 M hydrochloric acid) with amoxicillin at pH = 9.0 with the further reduction of the formed analytical form on a dropping mercury electrode. Voltammetric determination of amoxicillin is carried out due to the reduction peak of azo group of the obtained azo compound in the presence of 0.05 mol • L À 1 Na 2 B 4 O 7 as a background electrolyte at the potential E c p2 = À 0.55 V and potential sweep rate of 2.5 V • s À 1 . The developed voltammetric method has two linear ranges of the determined concentrations (0.05-2.0) • 10 À 5 mol • L À 1 and (0.2-1.0) • 10 À 4 mol • L À 1 and the high sensitivity: LOD without the removing of unreacted sodium nitrite is 1.1 • 10 À 6 mol • L À 1 , and 7.2 • 10 À 7 mol • L À 1 , when NaNO 2 excess is removed using urea. The developed voltammetric technique of AM determination has been approved during the analyses of tablets and oral suspension.
