“…Despite the good recovery (>70% for most analytes) obtained, acetone was also rejected because of the miscibility with water. MeCN can precipitate proteins and limit lipid solubility , thereafter, can minimize the co‐extraction of lipids and proteins. Hence, the water/MeCN (1:3, v/v) mixture solvent was used as extraction solvent in this study.…”

“…Despite the good recovery (>70% for most analytes) obtained, acetone was also rejected because of the miscibility with water. MeCN can precipitate proteins [41,42] and limit lipid solubility [26,27,43], Fig. 2, the highest recovery was obtained from the extractant containing 0.1% formic acid, which was conducive to the stability of pH-dependent pesticides [44,45].…”

“…In comparison, the low-temperature cleanup method exhibited many merits to determine pesticides in olive oil [23], honey samples [24] and fish tissue [8] samples. Most importantly, it involves only a straightforward operation and simple materials [25][26][27]. The main defect of this method was the low removing rate, and therefore the remained lipids in the solvent still interfere in the determination.…”

As a result of the low water content and high fat matrices in nuts, it is very difficult to simultaneously determine multi-pesticides in trace levels. Here, a sample pretreatment method was developed in which, microwave-assisted solvent extraction was firstly used to extract pesticides, and then a two-step cleanup method was conducted combining freeze-out with dispersive solid-phase extraction to remove the lipidic matrix. By this way, 106 pesticides were simultaneously determined in the complicated nut sample by using an ultra-high pressure liquid chromatography coupled with a tandem mass spectrometer. Average recoveries were 75.3-119.3% with relative standard deviations < 14% at three concentration levels. The limits of detection and quantification were in the ranges of 0.3-3.0 and 1.0-10.0 μg/kg, respectively. Furthermore, the method was successfully applied to the determination of pesticides in 180 commercial nut samples.

This study develops a simple, cost-effective and sensitive high-performance liquid chromatography with diode array detector (HPLC-DAD) method for the simultaneous determination of eight sulfonylurea herbicides (oxasulfuron, metsulfuron-methyl, triasulfuron, chlorsulfuron, amidosulfuron, mesosulfuron-methyl, bensulfuron-methyl and tritosulfuron) in rapeseed oil. Extraction of target analytes was performed using quick, easy, cheap, effective, rugged and safe-based procedure followed by solid-phase extraction (SPE) and dispersive solid-phase extraction (d-SPE) cleanup, and presents good performance for all of the analytes with recoveries in the range of 67-133% and relative standard deviations (RSD) less than 15%. No significant matrix interference was observed due to the application of effective zirconium dioxide-based sorbent (Z-Sep). Method LOQs for most of the investigated analytes were set at satisfactory low value of 20 ng g −1 in food product. The procedure was evaluated in analyses of actual samples. The most important steps of the method optimization are presented. Novel EMR-Lipid cleanup solution for samples with high fat content was evaluated and compared to Z-Sep sorbent.

“…Multiresidue analysis of 41 pollen samples collected from apiaries in agricultural areas of Spain between 2012 and 2015 showed residues of at least 2 pesticides and a mean of 6 pesticides per sample in the range 3.7-1856 ppb (Parrilla Vázquez et al 2015). The most commonly found chemicals were used for control of Varroa destructor (coumaphos, taufluvalinate, chlorfenvinphos, in 44-73% samples), followed by two fungicides (carbendazim and thiabendazole), the organophosphorus chlorpyrifos, and the neonicotinoid thiacloprid (29.3% samples).…”

With the exponential number of published data on neonicotinoids and fipronil during the last decade, an updated review of literature has been conducted in three parts. The present part focuses on gaps of knowledge that have been addressed after publication of the Worldwide Integrated Assessment (WIA) on systemic insecticides in 2015. More specifically, new data on the mode of action and metabolism of neonicotinoids and fipronil, and their toxicity to invertebrates and vertebrates, were obtained. We included the newly detected synergistic effects and/or interactions of these systemic insecticides with other insecticides, fungicides, herbicides, adjuvants, honeybee viruses, and parasites of honeybees. New studies have also investigated the contamination of all environmental compartments (air and dust, soil, water, sediments, and plants) as well as bees and apicultural products, food and beverages, and the exposure of invertebrates and vertebrates to such contaminants. Finally, we review new publications on remediation of neonicotinoids and fipronil, especially in water systems. Conclusions of the previous WIA in 2015 are reinforced; neonicotinoids and fipronil represent a major threat worldwide for biodiversity, ecosystems, and all the services the latter provide.
