The degradation dynamics and dietary risk assessments of thiamethoxam thiacloprid during Lonicera japonica planting, drying, tea brewing processes were systematically investigated using high-performance liquid chromatography. half-lives 1.0-4.1 d in the honeysuckle flowers leaves, with rate constants k ranging from -0.169 to -0.696. safety interval time was 7 d. sun- oven-drying (70 °C) percent digestions 59.4-81.0% for residues, which higher than shade- percentages at lower temperatures...
A multi-residue method for the determination of 54 pesticide residues in pollens has been developed and validated. The proposed was applied to analysis 48 crude pollen samples collected from eight provinces China. recovery analytes ranged 60% 136% with relative standard deviations (RSDs) below 30%. Of targeted compounds, 19 pesticides were detected. major detection rates each compound 77.1% carbendazim, 58.3% fenpropathrin, 56.3% chlorpyrifos, 50.0% fluvalinate, 31.3% chlorbenzuron, 29.2%...
In this study, a 30-days laboratory experiment was implemented to investigate the impact of additive biochar on stabilization heavy metals in chicken manure compost. Results showed that after addition rice straw-derived biochar, were more stabilized except Cu, which residual fractions distinctly decreased due interaction with organic functional groups from biochar. Given bioavailability metals, at 10% proportion concentration CaCl2-extractable Cr, Zn, Ni, and Cd. Besides, As did not differ...
Previous studies have only focused on the bioaccessibility of single pesticide/metal without considering potential impact post-uptake interactions pesticides/metals in human digestive system. Hence, influences chromium (Cr) speciation neonicotinoids were investigated and health risk based oral was evaluated. Bioaccessibility four apple pear measured using three common vitro methods (SBRC, PBET, IVG). varied between methods, which may reflect difference determination parameters (i.e., pH...
The transfer of pesticide residues from herbal teas to their infusion is a subject particular interest. In this study, multi-residue analytical method for the determination pyrethroids (fenpropathrin, beta-cypermethrin, lambda-cyhalothrin, and fenvalerate) in honeysuckle, chrysanthemum, wolfberry, licorice samples was validated. pyrethroid tea investigated at different water temperatures, tea/water ratios, intervals/times. results show that low amounts (0-6.70%) were transferred under...
This study examined how gastrointestinal conditions affect pesticide bioaccessibility and intestinal transepithelial transport of pesticides (difenoconazole, hexaconazole, spirodiclofen) in humans. We used an vitro model combining human gastric digestion, followed with Caco-2 cell for absorption. Bioaccessibility three tested ranged from 25.2 to 76.3% 10.6 79.63% the phases, respectively. A marked trend similar normal distribution was observed between pH, highest values at pH 2.12 juice. No...
Heavy metals contamination in soil from copper mine areas is a serious and widespread problem China. In this study, the content of Tl, Hg, Cu, Cd, Ni, Pb As probabilistic human health risks were investigated typical mining city. Copper showed highest average 184.29 mg/kg, followed by Pb, As, Cd Hg. Approximately 54.2% study sites moderately contaminated Tl. Among heavy metals, Cu relatively high mobility medium risk environment based on chemical speciation. particular, Tl was mainly present...
Rice-crayfish system has been extensively promoted in China recent years. However, the presence of toxic elements soil may threaten quality agricultural products. In this study, eight were determined multi-medium including soil, rice, and crayfish from rice-crayfish (RCS) conventional rice culture (CRC) area. Crayfish obtained a low level element content, mercury (Hg) RCS showed highest bioavailability mobility. Health risk assessment, coupled with Monte Carlo simulation, revealed that...
This study investigated the effects of light source, pH value, and NO3- concentration on photodegradation prothioconazole in aqueous solution. The half-life (t1/2) was 173.29, 21.66, 11.18 min under xenon, ultraviolet, high-pressure mercury lamps, respectively. At values 4.0, 7.0, 9.0 a xenon lamp t1/2 were 693.15, 231.05, 99.02 min, Inorganic substance clearly promoted prothioconazole, with 115.53, 77.02, 69.32 at concentrations 1.0, 2.0, 5.0 mg L-1, products identified as C14H15Cl2N3O,...
Humans are frequently exposed to the residues of various neonicotinoids, highlighting need understand human exposure through oral ingestion contaminated foods. In this study, effects different food matrices (tomato, cucumber, and carrot) their interaction with dietary component additives, including proteins fiber, was investigated. The results showed that presence a matrix had significant effect on bioaccessibility neonicotinoids (imidacloprid, thiamethoxam, acetamiprid, thiacloprid) in both...

From 9 39 16 whereas backcrossed 3 These data suggest presence or absence lint fuzz are controlled by interaction four gene loci on non‐homologous chromosomes. We designate these as N , Li 4 where confers fuzzy, inhibition fuzzy...
Abstract BACKGROUND Botanical pesticides increasingly play important roles in the control of agricultural pests. In this study, aphidicidal effect moso bamboo ( Phyllostachys pubescens ) extract against mustard aphid was confirmed, main active compounds identified, and mechanism most compound established. RESULTS When treatment concentration 10.0 g L −1 , corrected mortality leaf (BE) 53.22 ± 5.20% petroleum ether component (PE) reached 82.76 4.50%, which also showed a synergistic with...
The residue dynamics and risk assessment of prochloraz its metabolite 2,4,6-trichlorophenol (2,4,6-TCP) in apple under different treatment concentrations were investigated using a GC-ECD method. derivatization percent to 2,4,6-TCP was stable complete. recoveries 82.9%-114.4%, the coefficients variation (CV) 0.7%-8.6% for whole fruit, pulp, peel samples. Under application 2 °C 2.0 g/L, 1.0 20 g/L treatment, half-life degradation 57.8-86.6 d fruit peel, concentration pulp increased gradually...
The inhalation exposure of pesticide applicators and residents who live close to pesticide-treated fields is a worldwide concern in public health. Quantitative assessment health risk highlights the need accurately assess bioaccessibility rather than total content ambient air. Herein, we developed an vitro method estimate emamectin benzoate validated its applicability using rat plasma pharmacokinetic bioassay. Emamectin was extracted Gamble solution, with optimized solid-to-liquid ratio...
