“…Neonicotinoids are broadly classified into four generations: first-generation imidacloprid, NIT, acetamiprid, and thiacloprid; second-generation thiamethoxam and clothianidin; third-generation DNF; and fourth-generation cycloxaprid, sulfoxaflor, and imidaclothiz [22][23][24]. NIT NIT, (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N'-methyl-2-nitrovinylidenediamine, is a first-generation neonicotinoid with the closed formula C 11 H 15 ClN 4 O 2 (Figure 1).…”

Nitenpyram (NIT) and dinotefuran (DNF) are neonicotinoid pesticides commonly used in the production and storage of agricultural products, as well as in forests and gardens, for the purpose of protection from insect pests. Although they are safer for mammals, their toxic effects on pollinators, such as bees, and their long-term accumulation in water and soil, are important problems. Therefore, it is crucial to ensure that their usage remains within certain specific limits and that their residues are quickly, precisely, and reliably monitored in various samples. In this review, electrochemical methods, which are voltammetry, amperometry, and potentiometry, for the determination of NIT and DNF in pure solutions, agricultural, and environmental samples by using various modified electrodes were reviewed. The results obtained from studies published since 2011 were compared, and the effectiveness of the selected methods was demonstrated. It was observed that the electrochemical methods, particularly voltammetry, used in the studies conducted for NIT and DNF yielded selective and sensitive results at detection limits at nmol L–1 levels. These methods also exhibited high precision and accuracy without being affected by the matrix of the studied samples, such as soil, water, or agricultural products.

“…Studies suggested that imidacloprid (IMI) may pose a certain threat to invertebrates in aquatic ecosystems and has the potential to harm humans 7,8 . It has been reported that bees can be killed after exposure to as little as 36 ng IMI 9 . Therefore, it is of great practical significance to find new methods to remove NNIs effectively from natural environments.…”

BACKGROUND: With the rapid development of modern industry and agriculture, large amounts of sewage of various types are being discharged into water bodies every year, causing huge environmental pressure and posing a threat to organisms. Amongst different solutions to this problem, microalgae can remove pollutants including pesticides and antibiotics from water. In this work, an algal strain designated as Scenedesmus sp. TXH. was isolated from the Tangxun Lake Sewage Treatment Plant (Wuhan, China) and used to remove imidacloprid (IMI) from sewage. The removal efficiency, degradation products, removal of conventional contaminants [total dissolved nitrogen (TDN) ammonia nitrogen (NH 4 + -N), total dissolved phosphorus (TDP)], the biochemical response of the microalgae, and the effects of environmental factors such as light intensity and temperature were investigated. RESULTS:The results showed that: (i) the highest IMI removal efficiency of ≈60% was achieved under 80 ∼mol m −2 s −1 at 25 °C;(ii) the removal of NH 4 + -N, TDP and TDN in the sewage reached 90%, 90% and 65%, respectively; (iii) there was a significant linear relationship between the concentration of total chlorophyll and the removal of IMI in the sewage; and (iv) finally, based on the analysis of degradation products by mass spectrometer, three potential IMI degradation pathways were proposed.CONCLUSION: In summary, our results showed that Scenedesmus sp. TXH can remove IMI and conventional nutrients efficiently from sewage, implying a potential application in sewage treatment in the near future.

“…It is postulated that DNT affects the insect's nicotinic acetylcholine binding in a mode different from that of the other NEOs. Additionally, it has little neonicotinoid effect on fruit quality and a lower ecological risk [4]. The formulated DNT products are widely applied to soil, foliage, nursery boxes, and paddy water by drench, spray, and broadcast treatments.…”

Dinotefuran (DNT) belongs to the third-generation neonicotinoid pesticides, which are among the most common residuals in a variety of food commodities. To guarantee accurate quantification and traceability of results in food samples, certified reference materials (CRMs) are the indispensable benchmark. In this work, a DNT CRM was characterized and its purity was assessed by two independent methods, including mass balance (MB) and quantitative nuclear magnetic resonance spectroscopy (qNMR). The mass fraction of moisture was 0.33 mg/g, the inorganic impurity was 0.01 mg/g, and no detectable organic solvent was detected. Benzoic acid was chosen as the internal standard for qNMR. Its mass fraction was 997.9 mg/g and 992.9 mg/g by MB and qNMR, respectively. Eventually, the DNT CRM was assigned a mass fraction of 995 mg/g, with expanded uncertainty of 5 mg/g (k = 2). This CRM can be used to prepare calibrant solutions and is applicable to national routine monitoring of DNT residuals in agro-products and food.
