Abstract
Pesticides are omnipresent, and they pose significant environmental and health risks. Translational studies indicate that acute exposure to high pesticide levels is detrimental, and prolonged contact with low concentrations of pesticides, as single and cocktail, could represent a risk factor for multi-organ pathophysiology, including the brain. Within this research template, we focus on pesticides' impact on the blood-brain barrier (BBB) and neuroinflammation, physical and immunological borders for the homeostatic control of the central nervous system (CNS) neuronal networks. We examine the evidence supporting a link between pre- and postnatal pesticide exposure, neuroinflammatory responses, and time-depend vulnerability footprints in the brain. Because of the pathological influence of BBB damage and inflammation on neuronal transmission from early development, varying exposures to pesticides could represent a danger, perhaps accelerating adverse neurological trajectories during aging. Refining our understanding of how pesticides influence brain barriers and borders could enable the implementation of pesticide-specific regulatory measures directly relevant to environmental neuroethics, the exposome, and one-health frameworks.

Miniaturized QuEChERS extraction method for the detection of multi-residue pesticides in bat muscle tissue. Sci Rep 2022; 12:7164. [PMID: 35505235 PMCID: PMC9065137 DOI: 10.1038/s41598-022-11352-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 04/22/2022] [Indexed: 11/29/2022] Open
Abstract
Habitat loss and fragmentation are among the greatest threats to biodiversity and ecosystem stability, with physiological implications on wild fauna. Bats (Microchiroptera) are small mammals with a wide variety of eating habits, and the well-being of these animals is disturbed by exposure to pesticides. This study aimed to develop a miniaturized QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) extraction method for the detection of multi-residue pesticides in bat muscle tissue using gas chromatography coupled with mass spectrometry (GC–MS). A total of 48 pesticides were tested in 250 mg of bat muscle tissue. The developed analytical method was applied to 148 bats collected from two different areas in Minas Gerais State, Southeast Region of Brazil. The method presented good sensitivity and allowed the determination of residues of 48 pesticides in bat muscle using GC–MS. The miniaturized extraction method makes the analysis feasible even when the sample volume is limited. However, no pesticide residues were detected in bats from the two areas investigated.

Abstract
UNLABELLED Triazine herbicides have been widely used in agriculture, but their residues can harm the environment and human health. To help monitor these, we have developed an effective immunochromatographic strip test that can simultaneously detect 15 different triazines in grain samples (including ametryn, cyprazine, atraton, prometon, prometryn, atrazine, propazine, terbuthylazine, simetryn, trietazine, secbumeton, simazine, desmetryn, terbumeton and simetone). Based on our optimization procedure, the visual limit of detection (vLOD) for these triazines was found to be 2-10 ng/mL in assay buffer, and 0.02-0.1 mg/kg in grain samples. Four different grain matrices including corn, brown rice, wheat, and sorghum were studied and the test results showed no significant differences between the 15 triazines analyzed using this method. This test is simple, convenient, rapid, and low-cost, and could be an effective tool for primary screening of triazine residues in grain samples. ELECTRONIC SUPPLEMENTARY MATERIAL Supplementary material (UV-vis spectra of 15 nm-GNP; K2CO3 usage; cross reactivity; strip images for spiked rice, wheat and sorghum samples, UPLC-MS/MS parameters; gray values for strip optimization) is available in the online version of this article at 10.1007/s12274-022-4164-2.

Fipronil and Fipronil Sulfone Distribution in Chicken Feathers and Eggs after Oral and Dermal Exposure. Foods 2021; 10:foods10123077.

Abstract
This work aimed to investigate the bio-distribution and the persistence of fipronil and its primary metabolite fipronil sulfone after oral and dermal administration by simulating natural farming conditions. Fipronil and fipronil sulfone detection and quantification were performed in different poultry matrices using an LC-MS/MS method coupled with modified QuEChERS extraction. After oral administration, fipronil was detected in feathers at each sampling time, in eggs for 28 days, and in the internal organs at the end of the experiment. After dermal administration, high levels of fipronil were detected in feathers, accounting for 195.85 ± 8.54 mg/kg, which were reduced by a third after 60 days. No traces of fipronil were detected in the eggs or internal organs. In addition, fipronil sulfone showed remarkable residues in all samples in trial 2. The data obtained confirmed that inappropriate use of unauthorized pesticides can lead to severe contamination of entire poultry farms. The contemporary presence of fipronil sulfone in feathers and eggs associated with the lack of fipronil in eggs suggests recent dermal contamination or past oral contamination. Moreover, simultaneous analysis of hens’ feathers and eggs could represent a new method to improve large-scale monitoring programs and animal welfare, limiting their slaughter.

Abstract
A miniaturized sample preparation method was developed and validated for the multiresidue determination of 97 pesticides in wine samples. The proposed extraction procedure is based on the QuEChERS acetate method with dispersive solid phase extraction (d-SPE) for the clean-up step. Ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) was used for determination. The extraction and clean-up steps were evaluated to obtain the best conditions for the selected pesticides. Miniaturization of the sample preparation step provided a reduction in the consumption of samples and chemicals. The method limit of quantification was between 10 and 20 μg L-1. Trueness results, obtained by recovery assays at the spike levels 10, 20, 50 and 100 μg L-1, ranged from 70 to 120% with precision in terms of relative standard deviations (RSD) ≤ 20%. The method was successfully applied for the analysis of wine samples and different pesticides were found at concentrations from 14 to 55 μg L-1.

Abstract
The residues from the widely used broad-spectrum environmental herbicide, atrazine (ATR), result in the exposure of nontarget organisms and persist as a global major public health hazard. ATR is neurotoxic and may cause adverse health effects in mammals, birds, and fishes. Nevertheless, the molecular mechanism of ATR induced neurotoxicity remains unclear. To assess the molecular mechanisms of ATR-induced cerebral toxicity through potential oxidative damage, quail were treated with ATR by oral gavage administration at doses of 0, 50, 250, and 500 mg/kg body weight daily for 45 days. Markedly, increases in the amount of swelling of neuronal cells, the percentage of mean damaged mitochondria, mitochondrial malformation, and mitochondrial vacuolar degeneration as well as decreases in the mitochondrial cristae and mitochondrial volume density were observed by light and electron microscopy in the cerebrum of quail. ATR induced toxicities in the expression of mitochondrial function-related genes and promoted oxidative damage, as indicated by effects on oxidative stress indices. These results indicated that ATR exposure can cause neurological disorders and cerebral injury. ATR may initiate apoptosis by activating Bcl-2, Bax, and Caspase3 protein expression but failed to induce autophagy (LC3B has not cleaved to LC3BI/II). Furthermore, ATR induced CYP-related enzymes metabolism disorders by activating the nuclear xenobiotic receptors response (NXRs including AHR, CAR, and PXR) and increased expression of several CYP isoforms (including CYP1B1 and CYP2C18) and thereby producing mitochondrial dysfunction. In this study, we observed ATR exposure resulted in oxidative stress and mitochondrial dysfunction by activating the NXR response and interfering the CYP450s homeostasis in quail cerebrum that supported the molecular mechanism of ATR induced cerebrum toxicity. In conclusion, these results provided new evidence on molecular mechanism of ATR induced neurotoxicity.

Abstract
There are increasing concerns about the dietary risks of neonicotinoids (NNIs); therefore their sensitive and accurate determination in dietary products is indispensable. However, the complex composition of agricultural food matrixes makes their extraction and quantitative determination a challenging task. Realizing this need, we herein report a simple, cost-effective, selective and sensitive fluorescence analytical workflow for analyses of two non-fluorescent neonicotinoids imidacloprid (IMI) and clothianidin (CLT) in six complex food samples (honey, ginger, durian, apple, tomato, cucumber) by online clean-up of sample extracts using two-dimensional ion chromatography (2D-IC) and a subsequent online post column UV induced fluorescence detection system. This online clean-up setup has proven advantageous to improve the limit of detection, potentially diminish matrix effects, and reduce analysis time and labor. The developed method showed excellent analytical figures of merit including linearity, selectivity, repeatability, recovery, and resolution for analysis of IMI and CLT in food samples. A 2D-IC system was successfully fabricated for clean isocratic chromatographic separations and sensitive post column UV induced fluorescence determination of two NNIs in six complex food samples.![]()

Abstract
Atrazine (ATZ) is one of the most commonly used herbicides contaminating plants, soil and water resources. Several strategies have been used to counteract ATZ toxicity. Here, we tested the hypothesis that lycopene could ameliorate ATZ-induced toxicity in the adrenal cortex. For this purpose, 35 adult male albino rats were randomized into five equal groups: untreated control, vehicle control (received 0.5 mL corn oil/day), lycopene (treated with lycopene dissolved in 0.5 mL corn oil, 10 mg/kg b.w./day), ATZ (received ATZ dissolved in 0.5 mL corn oil 300 mg/kg b.w./day), and ATZ + lycopene (treated with ATZ and lycopene at the same previously mentioned doses). All treatments were given by oral gavage for 4 weeks. We found that ATZ exposure significantly increased relative adrenal weight, plasma ACTH levels, and adrenal oxidative stress as manifested by elevated malondialdehyde levels, decreased reduced glutathione content and depressed antioxidant enzyme activities in adrenal cortex tissues with respect to control groups. Furthermore, the transcription of adrenal cortex nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), nuclear factor kappa B, and caspase-3 genes was increased significantly compared with the control groups. This was accompanied with DNA fragmentation and structural and ultrastructural changes in zona glomerulosa and zona fasiculata of the adrenal cortex. Notably, all these changes were partially ameliorated in rats treated concomitantly with ATZ and lycopene. Our results showed that lycopene exerts protective effects against ATZ-induced toxicity in rat adrenal cortex. These effects may be attributed to the antioxidative property of lycopene and its ability to activate the Nrf2/HO-1 pathway.
