A convenient and rapid method that combines a fluorescent nanoprobe based on C-g-C<sub>3</sub>N<sub>4</sub>-Eu<sup>3+</sup> with smartphone test paper has been developed for the <italic>in situ</italic> detection of tetracyclines.
A rapid, sensitive, and effective multiresidue analytical method was established to investigate the degradation rate final residues of bifenthrin, bifenazate, its metabolite bifenazate-diazene in apples, dietary risk consumers evaluated. The apple samples from 12 different apple-producing areas China were determined by high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS). average recoveries three compounds apples 88.4-104.6%, relative standard deviations (RSDs)...
One simple, sensitive detection method for pesticide prothioconazole based on citrate-capped gold nanoparticles (AuNPs) in one step at room temperature was presented this study. Prothioconazole could be easily linked onto the AuNPs through a Au–S covalent bond, and undergo aggregation via hydrogen bonds formed among molecules. As result, color of AuNP solution changes from wine red to royal purple, which monitored by naked eyes UV–vis spectra. This label-free visual determine with...

Benziothiazolinone is the first independently developed fungicide in China. It has been used to effectively control fungal diseases a variety of fruits, vegetables, and crops. In this study, degradation behavior final residue benziothiazolinone apples discussed, dietary risk consumers was evaluated. High-performance liquid chromatography–tandem mass spectrometry (LC-MS/MS) determine residues apple samples from eight different regions The average recovery 85.5–100.2%, relative standard...
Pyraclostrobin is a new broad-spectrum methoxyacrylic acid fungicide. Cyazofamid selective foliar spray acaricide. Here, we studied the degradation rate and final residues of pyraclostrobin cyazofamid in grape evaluated their dietary risk to consumers. The average recoveries ether ester, metabolite (CCIM) grapes were 84–94%, 92–98% 99–104%, respectively. relative standard deviations (RSDs) 6.0–20.3%, 2.4–10.5% 1.3–4.0%, respectively, LOQs all 0.05 mg/kg. digestion dynamics experimental sites...
Abstract Tracing the herbicide bixlozone and its metabolites in food is necessary to assess their risks human health. In study, a rapid effective analytical method using quick, easy, cheap, effective, rugged, safe for simultaneous determination of (2,4‐dichlorobenzoic acid, 3‐hydroxy‐propanamide‐bixlozone, 5′‐hydroxy‐bixlozone) plant animal samples (tomato, cucumber, apple, wheat flour, meat, milk, egg) was developed based on ultra high performance liquid chromatography–tandem mass...
Metalaxyl-M and azoxystrobin have been used to control various fungal diseases on scallion other crops. In view of the adverse toxic effects both mammalian liver, it is necessary conduct a cumulative risk assessment their dietary exposure consumers. The residues metalaxyl-M were determined by quick, easy, cheap, effective, rugged, safe method (QuEChERS) combined with high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS). half-lives about 1.15 3.89 days, respectively,...
DNA damage can occur naturally or through environmental factors, leading to mutations in replication and genomic instability cells. Normally, natural d-nucleotides were selected by polymerases. The template l-thymidine (l-T) has been shown be bypassed several types of However, fidelity nucleotide incorporation opposite vivo remains unknown. Here, we constructed plasmids containing a restriction enzyme (PstI) recognition site which the l-T lesion was site-specifically located within PstI...
Abstract The purpose of this study was to investigate the influence four kinds Lactic acid bacteria (LAB) on stereoselective degradation theta ‐cypermethrin (CYP), including Lactobacillus plantarum , casei delbrueckii and Streptococcus thermophilus . An effective analytical method for (±)‐ ‐CYP in medium developed by high‐performance liquid chromatography with cellulose tris‐(3,5‐dimethylphenylcarbamate) chiral stationary phase. ‐Cypermethrin spiked LAB different inoculation rates sampled at...
In recent years, illegal cooking oil incident led to the serious food safety risks and negative social repercussions. this paper, copper ions cationic gold nanoparticles modified by poly(diallyl dimethylammonium) chloride (PDDA) were used as recognition probes. Two rapid convenient colorimetric detection methods of oils based on phase transfer technology established. The results showed that qualified mixed with 2.8% could be detected, more than 5% detected accurately naked-eye. These applied...
