Imidacloprid is one of the most commonly used insecticides for managing pests, thus, improving quality and yield vegetables. The abuse/misuse imidacloprid contaminates environment threatens human health. To reduce risk, a colorimetric enzyme-linked immunoassay assay (Co-ELISA) chemiluminescence (Cl-ELISA) were established to detect residues in linear range Co-ELISA ranged between 1.56 μg/L 200 with limit detection (LOD) μg/L. values Cl-ELISA 0.19 25 an LOD μg/L, which are lower than those...
Magnetic solid-phase extraction is an effective and convenient sample pretreatment technique that has received considerable interest in recent years. A lot of research indicated magnetic nanocarbon-material-based composites have good application prospects as adsorbents for pesticides. Herein, a novel zeolitic imidazolate framework based on multiwalled carbon nanotubes (M-M-ZIF-67) been prepared adsorbent nine organochlorine pesticides from agricultural irrigation water samples. The obtained...
A simple, sensitive and effective magnetic solid-phase extraction (MSPE) technique was developed for the of pyrethroid pesticides from environmental water samples, followed by gas chromatography tandem triple quadrupole mass spectrometry determination. An adsorbent zeolitic imidazolate framework-8@deep eutectic solvent (M-ZIF-8@DES) prepared using deep coated on surface M-ZIF-8. The features M-ZIF-8@DES were confirmed material characterizations, results indicated that has a good magnetism...
A novel magnetic zinc-based zeolitic imidazolate framework (MMP/ZIF-8) has been prepared using a multiwalled carbon nanotube@polydopamine nanocomposite as the core and support. It was then used an adsorbent for solid-phase extraction of triazole fungicides from environmental water samples. Successful synthesis MMP/ZIF-8 confirmed by material characterization, results showed that synthetic composite high Brunauer-Emmett-Teller surface area (141.56 m2 g-1), large total pore volume (0.636 mL...
A magnetic graphene/polydopamine (MG/PDA) nanocomposite has been prepared and used as sorbent for dispersive solid-phase extraction (MDSPE) of four benzoylurea insecticides in environmental water samples. The obtained nanocomposites were characterized by transmission electron microscopy, scanning vibrating sample magnetometry, powder X-ray diffraction, fourier transform infrared spectroscopy, surface area porosity analysis thermogravimetric analysis. To investigate the adsorption performance...
A simple, sensitive, and reliable magnetic solid-phase extraction (SPE) method coupled with GC-MS/MS for the effective analysis of four pyrethroids from tea infusions was developed. adsorbent, named ionic liquid-modified zeolitic imidazolate framework-8 (Fe3O4/ZIF-8/IL), prepared by immobilizing an liquid (IL) on surface Fe3O4/ZIF-8. The textures Fe3O4/ZIF-8/IL were confirmed material characterization, results suggested that adsorbent possessed high magnetism (59.0 emu g-1), adequate...
The Yellow-Bohai Sea is an important semi-enclosed continental shelf marginal seas with intensive aquaculture industry in China. current study analyzed the contamination status and time variations of paralytic shellfish toxins (PSTs) between 2019 2020 from Dalian area estimated acute health risks to consumers A total 199 samples (including 34 Pacific oysters, 25 Mediterranean blue mussels, Manila clams, 36 bay scallops, veined rapa whelks bloody clams) were four representative zones around...
Multi-residue determination of pesticides in a complex matrix by online gel permeation chromatography-gas chromatography/mass spectrometry (GPC-GC/MS) is increasingly concerned for its high throughput, efficiency and accuracy. Study matrix-induced suppression or enhancement the instrument signals important application this technique.Matrix effects 176 were studied GPC-GC/MS post-extraction addition. Suppression induced co-eluted compounds examined matrices tea human breast milk. The prepared...
Aflatoxin M1 (AFM1) is the only mycotoxin that has a legal limit in milk all over world. In present study, 360 raw samples were collected from Beijing, Hebei, Shanxi, Shanghai and Guangdong provinces China September 2010, their AFM1 levels determined by using enzyme-linked immunosorbent assay (ELISA). More than three-fourths (78.1%) of contained at concentrations 5-123 ng L⁻¹. contents positive far below Chinese US 500 L⁻¹, but 10% exceeded EU 50 Moreover, both incidence content southern...
Currently, bilateral pedicle screw fixation is the standard of instrumentation, providing rigid and an increased fusion rate. However, due to excessive rigidity system, this instrumentation has been suspected cause degeneration adjacent segments. Alternatively, less unilateral considered be as effective constructs. Few studies have compared constructs in treatment lumbar degenerative disease. The purpose retrospective study was evaluate possible differences between for single-level Between...
