Pesticide residues in cowpeas have raised worldwide concern. However, only a few studies focused on pesticide accumulation and distribution greenhouse open-field cowpeas. Field trial results suggest that difenoconazole, dimethomorph, thifluzamide pyraclostrobin dissipated faster open fields (mean half-lives, 1.72-1.99 days) than greenhouses (2.09-3.55 days); moreover, fungicide were 0.84-8.19 times higher those the All fungicides accumulated after repeated spraying. Fungicide old tender...
Abstract A dispersive solid‐phase extraction coupled with ultra high performance liquid chromatography tandem mass spectrometry method was developed and validated for the simultaneous determination of T‐2 toxin, penicillic acid, fumonisins B 1 , 2 3 aflatoxins G ochratoxin A, deoxynivalenol, 3‐acetyldeoxynivalenol, 15‐acetyldeoxynivalenol, zearalenone in chestnut samples. The used to analyze 136 samples obtained from Shandong province China. mycotoxins were extracted using a cleaned an...
Abstract The antimonate compound La 3 SbO 7 has high chemical stability, lattice stiffness and thermal stability. Orange–red‐emitting antimonate‐based phosphors : x Sm 3+ ( = 0.02, 0.05, 0.08, 0.10, 0.15, 0.20 0.25) were synthesized. phase structure photoluminescence properties of these investigated. emission spectrum obtained on excitation at 407 nm contained exclusively the characteristic emissions 568, 608, 654 716 nm, which correspond to transitions from 4 G 5/2 6 H , 7/2 9/2 11/2...
The experiment developed the ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC/MS/MS) method for testing emamectin benzoate, and studied metabolism of benzoate in rice plants rice-growing environments via application this method. dissipation curve standard substance was good at 0.5-200 μg L-1, its correlation coefficient greater than 0.99. In concentration range 0.1-50 kg-1, average recovery rate plants, soil, field water 82 %-102 %, relative deviation (RSD) between...
Honeysuckle is a commonly used medicine for health care and treatment. To detect heavy metal pollution in honeysuckle from China quantify the risk of via dietary intake, Pb, Cd, Cr, As, Hg, Ni, Mn, Cu, Zn contents samples were determined by ICP-MS. The dissolution rate metals was measured decoction soaking. hazard quotient (HQ) total index (HI) to evaluate noncarcinogenic nine honeysuckle, carcinogenic risks Cd As evaluated using carcinogen risk. exhibited maximum permissive limit...
Fluopyram and trifloxystrobin are widely used for controlling various plant diseases in cucumbers cowpeas. However, data on residue behaviors cultivation food processing currently lacking. Our results showed that cowpeas had higher fluopyram residues (16.48–247.65 μg/kg) than (877.37–3576.15 μg/kg). Moreover, dissipated faster (half-life range, 2.60–10.66 d) (10.83–22.36 d). were the main compounds found field samples, their metabolites, benzamide acid, fluctuated at low levels (≤76.17...
In this study, 321 chestnut samples from Shandong Province in China were analysed for the presence of mycotoxins. We screened 14 mycotoxins including aflatoxins (AFs: AFB1, AFB2, AFG1, AFG2), deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), T-2 toxin (T-2), zearalenone (ZEA), ochratoxin A (OTA), fumonisins (FB1, FB2, FB3), and penicillic acid (PeA). Mycotoxins detected 56.4% samples, 11 these found. Thirty markets deemed positive AFs (9.3%) had an...
Oxine-copper, which is used as a disinfectant for vegetables, was determined by high-pressure liquid chromatography (HPLC) with an ultraviolet detector. The calibration relationship linear from 0.025 µg mL−1 to 20 and good precision obtained. recovery between 72.8 113.8%. limits of quantification were 0.1 mg kg−1 in soil 0.05 pears. half-lives oxine-copper pears 2011 2012 7.1 days 7.8 Hebei, 10.1 10.4 Shandong, 4 8.9 Henan. 8.1 9.1 6.8 8.6 9.7 maximum residue 1.64 kg−1.
Considering the advantages of silicon-based microelectronic devices and excellent photophysical properties halide perovskites, perovskites are expected to demonstrate great potential for application in field optoelectronic devices. In this paper, an antisolvent-assisted strategy is used prepare MAPbBr 3 perovskite microcrystals on silicon substrates, dense, continuous, smooth microcrystal thick films further obtained after hot-press treatment. Finally, n-Si/perovskite film/carbon structure...
Triazole fungicides (TFs) are extensively used on greenhouse vegetables and ubiquitously detected in the environments. However, human health ecological risks associated with presence of TFs soils not clear. In this study, ten widely were measured 283 soil samples from vegetable greenhouses across Shandong Province, China, potential assessed. Among all samples, difenoconazole, myclobutanil, triadimenol, tebuconazole top TFs, detection rates 85.16–100%, while those had higher residues, average...
