the current research presents a very simple method for the colorimetric detection of imidacloprid using a graphene quantum dot/Au (iii) chemosensor. the results demonstrated that there is an interaction between Au 3+ ions and the imidazole group of the pesticide toward reduction of Au 3+ to Au 0 in the presence of graphene quantum dots. this phenomenon changes the color of gold nanoparticles from yellow to grey or red, and causes a shift in the peak of localized surface plasmon resonance (LSpR) as gold nanoparticles are formed or aggregated based on the concentration of imidacloprid. Imidacloprid was determined by the developed sensor in a linear area of 0.01-1 ppm with a detection limit of 0.007 ppm. Therefore, a simple, quick, and sustainable sensor has been developed for the determination of the investigated analyte. Moreover, the sensor was applied to determine imidacloprid in the real cucumber samples fairly successful. Insecticides have a vital role in protecting plants from insects and pests. Neonicotinoid insecticides are increasingly being replaced by organophosphorus and carbamate pesticides to control sucking pests 1. Within the neonicotinoid pesticide group, imidacloprid (N-{1-[(6-chloro-3-pyridyl)methyl]-4,5-dihydroimidazol-2-yl}nitramide) is the second pesticide in terms of popularity in the world 2. It has adverse effects on human health. In recent years, the excessive use of pesticides has caused an increase in their residues in agricultural products, especially in greenhouse products such as cucumber and tomato. For this reason, acceptable daily intakes (ADIs) and maximum residue levels (MRLs) were established by international organizations as the criteria to prevent the adverse health effects of pesticide residues 3. The MRL and ADI for imidacloprid in cucumbers are set to 1 mg/kg and 0.06 mg/kg of body weight every day, respectively 4. Currently, a variety of methods, such as gas chromatography (GC), liquid chromatography-mass spectrometry (LC-MS), high-performance liquid chromatography (HPLC), the enzyme-linked immunosorbent assay, and electrochemical methods have been employed in the detection of imidacloprid 1. Although these methods are highly accurate, some disadvantages, such as high cost, onerous time requirements, and unreliability for real-time detection make them suitable for rapid measurements. So it is necessary to develop new and reliable methods, such as colorimetric methods, for rapid detection of imidacloprid. Nanotechnology is an interdisciplinary area of research that has grown globally in the last few decades 5. Among nanostructures, graphene quantum dots (GQDs) and gold nanoparticles (AuNPs) have attracted particular attention 6. GQDs are the sheets of graphene with the size of less than 100 nm that have same properties to graphene 7. Recently, GQDs were used as reducing agents for synthesizing metallic nanoparticles in sensor applications. Amjadi et al. 8 applied GQDs as the reducing agent for the construction of a GQD/Ag nanocomposite. Gold nanoparticles are used in produc...

“…For example, in streams and watersheds in agricultural areas, shortly after crop planting clothianidin had maximum concentrations detected in water of about 0.25 μg L −1 , which dropped to 0.025 μg L −1 later in the growing season (August; Hladik et al., 2014; Struger et al., 2017). Even in a single storm event, there tends to be an initial flush of neonicotinoids, with greater concentrations at the beginning of a storm event compared with the rest of the storm (Batikian, Lu, Watanabe, Pitt, & Gersberg, 2019). Overall, concentrations detected in this study (Table 1) were consistent with previous studies (Bradford, Huseth, & Groves, 2018; Chrétien et al., 2017; Hladik, Corsi, et al., 2018; Hladik et al., 2014, 2017; Klarich et al., 2017).…”

Assessing surface and subsurface transport of neonicotinoid insecticides from no‐till crop fields

Increased use of neonicotinoid-coated crop seeds introduces greater amounts of insecticides into the environment, where they are vulnerable to transport. To understand the transport of neonicotinoids from agricultural fields, we planted maize (Zea mays L.) seeds coated with thiamethoxam in lysimeter plots in central Pennsylvania. Over the next year, we sampled water generated by rainfall and snowmelt and analyzed these samples with mass spectrometry for the neonicotinoids thiamethoxam and clothianidin (metabolite), which originated from the coated seeds. For surface and subsurface transport, thiamethoxam exhibited "first-flush" dynamics, with concentrations highest during the first events following planting and generally decreasing for the remainder of the study. The metabolite clothianidin, however, persisted throughout the study. The mass of thiamethoxam and clothianidin exported during the study period accounted for 1.09% of the mass applied, with more than 90% of the mass transported in subsurface flow and less than 10% in surface runoff. These results suggest that surface runoff, at least for our site, is a relatively small contributor to the overall fate and transport of these insecticides and that the delivery ratio (i.e., mass exported/mass applied) observed for these compounds is similar to those of other trace-level emerging contaminants known to negatively influence aquatic ecosystems.

“…Quanto O potencial poluidor dos neonicotinóides é alto, uma vez que apresentam elevada solubilidade, persistência no ambiente aquático e são susceptíveis ao transporte, podendo atingir áreas adjacentes e corpos hídricos próximos às lavouras (Armbrust and Peeler 2002;Hilton et al 2016;Batikian et al 2019;Saggioro et al 2019). Assim, a movimentação destes pesticidas para outros ambientes representa um grande risco para organismos presentes nestas áreas, uma vez que já tem sido demonstrado que estes compostos podem causar impactos na estrutura da comunidade biótica de organismos não-alvo.…”
