“…A very extensive and systematic review of the analytical methods for studies of risk management and risk assessment of neonicotinoid insecticides was reported by Watanabe. [24] Here, analytical methods based on chromathographic and nonchromathographic techniques were described and summarized. Using complicated methods based on the automated flow fluorescent immunoassay, a sensitivity of 30 pg/ml thiamethoxam was reported by Kim et al, [25] and enzyme immunoassay using enzyme-labelled antigens a sensitivity of 0.5 ng/ml thiamethoxam was achieved, [26] respectively.…”

This study deals with the use of laser techniques for preparation of advanced Ag nanostructure on quartz substrates that can be applied in high‐resolution analyses, namely, surface enhanced Raman spectroscopy (SERS). The active system was a two dimensional array of nanoparticles produced by laser annealing of thin silver film. The optical and morphological properties of the nanostructure were compared with those of an as deposited thin film in order to estimate their role in the detection efficiency. The activity of the structures fabricated as substrates for SERS of usually applied in agricultural medicine small quantities of Aktara 25 BG (thiamethoxam) insecticide was tested. To the best of our knowledge, SERS spectra of Aktara 25 BG are presented for the first time. The minimum detected concentration of thiamethoxam was evaluated to be in the order of μg/ml. The simple fabrication method and demonstrated efficiency focus the presented study to direct bearing on the human health and food quality area as a way of assisting the detection of small amounts or residue of harmful pollutants.

“…For the analysis of neonicotinoids liquid chromatographic methods [15] are generally used, although immunoanalytical [16,17] and gas chromatographic methods (GC) were also reported. Due to heat sensitivity of some of these target compounds, derivatization and/or complicated sample pretreatment are required prior to GC measurements.…”

“…Determination of these ingredients from complex matrices (e.g., foods) requires more complicated sample preparation, as the coextracted substances often interfere with target compounds; thus clean-up cannot be omitted and selective detection mode (e.g., LCMS/MS) is necessary. For the extraction of imidacloprid from soil polar solvents (water, methanol, and acetonitrile) have been applied [15]. In the case of TMX microwave assisted extraction and water as solvent [27] have been used for the extraction of residues from vegetable and soil samples.…”

Movement of two neonicotinoid insecticide active ingredients, clothianidin (CLO) and thiamethoxam (TMX), was investigated in different soil types (sand, clay, or loam) and in pumice. Elution profiles were determined to explore differences in binding capacity. Soil characterized by high organic matter content retained the ingredients, whereas high clay content resulted in long release of compounds. Decrease in concentration was strongly influenced by soil types: both CLO and TMX were retained in loam and clay soils and showed ready elution through sandy soil and pumice. Elution capability of the active ingredients in sandy soil correlated with their water solubility, indicating approximately 30% higher rapidity for TMX than for CLO. Soil organic carbon-water partitioning coefficients (Koc) determined were in good agreement with literature values with somewhat lower value for CLO in sandy soil and substantially higher values for TMX in clay soil. High mobility of these neonicotinoid active ingredients in given soil types urges stronger precautionary approach taken during their application.

“…Previous techniques based on high-performance liquid chromatographic (HPLC) combined with UV, photo-diode array (PDA), MS, and MS/MS for the monitoring ICP and 6CA [4][5][6] have crucial drawbacks: 1) all of the methods consume large quantities of toxic organic solvents, acetonitrile and/or methanol, 7 in the mobile phases. Risk associated with these solvents extend beyond direct implications for the health of humans and wildlife to affect our environment and the ecosystem in which we all reside.…”

This paper describes a harmless HPLC technique for detecting imidacloprid (ICP) and its metabolite, 6-chloronicotinic acid (6CA), using an isocratic 100 % water mobile phase. Chromatographic separations were performed a Daisopak® SP-200-3-C1-P with water mobile phase and a photodiode-array detector. The total run time was < 6 min. The system suitability was well within the international acceptance criteria. The detection limits were 0.018 μg/ml for ICP and 0.005 μg/ml for 6CA, respectively. A harmless HPLC method for simultaneous detecting ICP and 6CA was developed and may be further applied to the quantification in animal-derived foods.
