“…Neonicotinoid insecticides (neonics) are one of the most used classes of insecticides worldwide for pest control in residential and agricultural fields [ 1 , 2 ]. They appeared in the 1990s, reaching a market share of more than 25% of the global insecticides sales in 2014, with an annual global sale of more than $3.5 billion [ 2 , 3 , 4 ].…”

“…Imidacloprid, acetamiprid, and thiacloprid exhibit the same cloropyridine moiety as nicotine, whereas thiamethoxam comprises a clorothiazole group [ 2 ]. Neonics can be classified into three main groups, namely N-nitroguanidines that include, for example, imidacloprid and thiamethoxam, nitromethylenes, and N-cyanoamidines, which comprises, for instance, acetamiprid [ 3 ].…”

“…Due to their broad-spectrum of insecticidal activity, the versatility of application modes (e.g., in spray, seed treatment, injections), and high potential toxicity towards insects, neonics appeared as promising substitutes of conventional insecticides, such as organophosphates, carbamates, and synthetic pyrethroid pesticides [ 1 , 2 ], is widely used and available in more than 120 countries [ 3 ]. However, neonics can persist in soil, water, and biota [ 2 ], being already detected in surface water [ 5 ], seed treatments [ 6 ], drinking water [ 7 ], wastewater treatment plants [ 8 ], wetland [ 8 ], house dust [ 9 ], air [ 10 ], and food [ 11 ].…”

Neonicotinoids are systemic insecticides commonly used for pest control in agriculture and veterinary applications. Due to their widespread use, neonicotinoid insecticides (neonics) are found in different environmental compartments, including water, soils, and biota, in which their high toxicity towards non-target organisms is a matter of great concern. Given their widespread use and high toxicity, the development of strategies to remove neonics, while avoiding further environmental contamination is of high priority. In this work, ionic-liquid-based materials, comprising silica modified with tetraalkylammonium cations and the chloride anion, were explored as alternative adsorbent materials to remove four neonics insecticides, namely imidacloprid, acetamiprid, thiacloprid, and thiamethoxam, from aqueous media. These materials or supported ionic liquids (SILs) were first synthesized and chemically characterized and further applied in adsorption studies. It was found that the equilibrium concentration of the adsorbate in the solid phase decreases with the decrease in the SIL cation alkyl chain length, reinforcing the relevance of hydrophobic interactions between ionic liquids (ILs) and insecticides. The best-identified SIL for the adsorption of the studied insecticides corresponds to silica modified with propyltrioctylammonium chloride ([Si][N3888]Cl). The saturation of SILs was reached in 5 min or less, showing their fast adsorption rate towards all insecticides, in contrast with activated carbon (benchmark) that requires 40 to 60 min. The best fitting of the experimental kinetic data was achieved with the Pseudo Second-Order model, meaning that the adsorption process is controlled at the solid-liquid interface. On the other hand, the best fitting of the experimental isotherm data is given by the Freundlich isotherm model, revealing that multiple layers of insecticides onto the SIL surface may occur. The continuous removal efficiency of the best SIL ([Si][N3888]Cl) by solid-phase extraction was finally appraised, with the maximum adsorption capacity decreasing in the following sequence: imidacloprid > thiacloprid > thiamethoxam > acetamiprid. Based on real reported values, under ideal conditions, 1 g of [Si][N3888]Cl is able to treat at least 106 m3 of wastewater and water from wetland contaminated with the studied neonics. In summary, the enhanced adsorption capacity of SILs for a broad diversity of neonics was demonstrated, reinforcing the usefulness of these materials for their removal from aqueous matrices and thus contributing to preventing their introduction into the ecosystems and reducing their detrimental effects in the environment and human health.

Due to its rich health benefits and unique cultural charm, tea drinking is increasingly popular with the public in modern society. The safety of tea is the top priority that affects the development of tea industry and the health of consumers. During the process of tea growth, pesticides are used to prevent the invasion of pests and diseases with maintaining high quality and stable yield. Because hot water brewing is the traditional way of tea consumption, water is the main carrier for pesticide residues in tea into human body accompanied by potential risks. In this review, pesticides used in tea gardens are divided into two categories according to their solubility, among which water-soluble pesticides pose a greater risk. We summarized the methods of the sample pretreatment and detection of pesticide residues and expounded the migration patterns and influencing factors of tea throughout the process of growth, processing, storage, and consumption. Moreover, the toxicity and safety of pesticide residues and diseases caused by human intake were analyzed. The risk assessment and traceability of pesticide residues in tea were carried out, and potential eco-friendly improvement strategies were proposed. The review is expected to provide a valuable reference for reducing risks of pesticide residues in tea and ensuring the safety of tea consumption.

Deposition of particulate matter (PM) from a variety of sources onto pollinator habitat is a largely unexplored source of risk to pollinators. Synthetic steroid growth promoters, antibiotics, and multiple pesticides have been detected in fugitive beef cattle feedyard PM. Subsequently, many of these chemicals determined to be associated with PM have been detected on flowers near beef cattle feedyards, as well as bees visiting those flowers. Therefore, there is a need to assess risk to pollinators posed by deposition of PM and agrochemical-laden PM, both in the field and the laboratory. Unfortunately, there are no established laboratory methods for simulating PM exposure or toxicity associated with contaminated PM. Herein we describe development and utilization of a PM circulation system that can be employed in the laboratory under controlled conditions. Two model organisms (honeybees (Apis mellifera) and mason bees (Osmia lignaria)) were exposed to agrochemical-free PM in the circulator system, and post-exposure mortality was compared with controls. No significant differences in mortality between exposed and control bees were observed. These results confirm the validity of these methods for use in laboratory-controlled PM exposure experiments, and offer a source of positive and negative control groups for laboratory and field experiments examining exposure of pollinators to potentially toxic chemical-laden PM.
