Nano-TiO2 as an antimicrobial inorganic material, can stimulate cells to produce reactive oxygen species and exhibit effective biochemical properties; however, phenylpyrazole derivatives, organic pesticides, are widely used in agriculture food. To find novel pesticides with environmental friendliness, combined three-dimensional quantitative structure-activity relationship (3D-QSAR) prediction analysis, three types of alkaloidal amine derivatives (PA) were synthesized by a one-pot microwave method. Based on the dye sensitization strategy, four nano-organometallic (PT) prepared organic-inorganic hybridization. PA PT showed 2.5 5.2 times higher insecticidal activity against P. xylostella than fipronil, had 3.9 greater antibacterial A. tumefaciens. The synergistic effect realizes balance amphiphilicity, enhances biological PT, improves phloem fluidity, promotes absorption transportation substances. In addition, this reduces band gap width, light capacity, induces active free radicals (ROS: ·O2-, ·OH), destroys cytomembrane so that better enter cell, resulting cell death. has excellent natural self-degradation performance converts parent moiety, which greatly residues, implying pesticide provides new idea for its degradation fluorescence detection residues.

The overuse of fipronil (FPN, a broad-spectrum insecticide) in agriculture has brought great concerns for environmental pollution and food safety. development rapid, reliable, portable analytical method the on-site monitoring FPN is therefore significance but full challenge. Herein, novel supramolecular probe using human serum albumin (HSA) as host an aggregation-induced emission-active fluorescence LIQ-TPA-TZ guest was developed colorimetric ratiometric detection FPN, displaying fast response (30 s), high sensitivity (LOD ∼ 0.05 μM), good selectivity anti-interference performance. Moreover, paper-based test strips could be facilely obtained utilized determination showing changes from yellow to orange. This also demonstrated potential real applications choosing best cleaning reduce residue rate on apples. study provides versatile tool real-time analysis which greatly benefits pesticides with use simple testing apparatus.

Abstract γ‐aminobutyric acid (GABA) is one of the main neurotransmitters involved in adaptation processes against damage that hypoxia can cause to brain. Due its antagonist action on GABA receptors, insecticide fipronil turn fish more susceptible negative effects hypoxia. This study aimed understand better if affects these GABAergic responses Tilapia ahead Oreochromis Niloticus (Nile Tilapia) were exposed for 3 and 8 h (0.0, 0.1, 0.5 µg.L −1 ) under normoxia (dissolved O 2 > 6 mg.L moderate < conditions. Briefly, caused opposite gene transcription evaluated ionotropic metabotropic receptors. Unexpectedly, we obtained reduced HIF1A mRNA brain levels, mostly first experiment, hypoxic group compared with one. Besides that, also demonstrated impairs signaling a hypoxia‐tolerant during transition from normoxic an acute state. Thus, results predict relevant impact metabolic adaptations fishes such stressful conditions aquatic environment, as well hypoxia, which may have ecological physiological significance this insecticide.

Benzophenone-3, fipronil and propylparaben are micropollutants that potential threats to ecosystems have been detected in aquatic environments. However, studies involving the investigation of new technologies aiming at their elimination from these matrices, such as advanced oxidation processes, remain scarce. In this study, different iron complexes (FeCit, FeEDTA, FeEDDS FeNTA) were evaluated for degradation a mixture (100 µg L−1 each) spiked municipal wastewater treatment plant (MWWTP) effluent pH 6.9 by solar photo-Fenton. Operational parameters (iron H2O2 concentration Fe/L molar ratio) optimized each complex. Degradation efficiencies improved significantly increasing (1:1 Fe/L) 12.5 100 µmol FeEDDS, FeEDTA FeNTA. The maximum reached with FeCit all concentrations was limited 30%. Different ratios required maximize efficiency ligand: 1:1 FeNTA 1:3 1:5 FeCit. Considering best ratios, higher rates using 5.9 mmol compared 1.5 2.9 FeCit, respectively. Acute toxicity Canton S. strain D. melanogaster flies reduced after complexes, indicating formation low-toxicity by-products. considered complex source terms kinetic constant (0.10 > 0.063 0.051 0.036 min−1 FeNTA, respectively), organic carbon input cost-benefit (USD 327 m−3 USD 20 16 13 respectively) when other tested complexes.
