The choice of formulation is influenced by the following factors: the physical properties of the pesticide (melting point, solubility, and volatility), the chemical properties of the pesticide (hydrolytic stability, thermal stability, and irradiation stability), the mode of application of the formulation (soil, foliar), the crop to be treated and the agricultural practices, the biological prope...

In this study, a QuEChERS method and gas chromatography coupled with time-of-flight mass spectrometry (GC×GCTOFMS) was developed for rapid extraction and simultaneous determination of 12 pesticide residues in honey. The GC×GC-TOFMS method was validated according to the SANCO guidance in terms of linearity, selectivity, reproducibility and recovery. Regarding the results, recovery rates ranged b...

The inappropriate or unlawful use of pesticides on agricultural crops can result in unacceptably high levels of these compounds, and their metabolites, in produce destined for human consumption. To protect the health of consumers, many countries stipulate Maximum Residue Levels (MRLs) for each pesticide compound in a range of fruit and vegetables. Worldwide, there are over 800 compounds current...

The conventional analysis of pesticide residues in analytical commodities, such as tobacco and tobacco products is a labor intensive procedure, since it is necessary to cover a wide range of different chemicals, using a single procedure. Standard analysis methods include extensive sample pretreatment (with solvent extraction and partitioning phases) and determination by GC and HPLC to achieve t...

Tebuconazole is a triazole fungicide used in agriculture to treat pathogenic fungi. It listed as possible carcinogen and it shows potential risk for the environment at very low concentration. Therefore, detection monitoring of tebuconazole food play an important role. The current methods analysis employ gas-liquid chromatography (GLC) high-performance liquid (HPLC) after sample extraction with ...

A rapid and simple multiresidue method has been established for determination of pesticide residues in processed foods by GC/MS/MS. The pesticides were extracted with ethyl acetate, and were cleaned up with a double-layered SPE cartridge column (graphite carbon black/PSA silica gel). Recovery tests of 258 pesticides from five kinds of processed foods (dumpling, curry, French fries, fried chicke...

Pesticide contamination has severely attacked the ecosystem and food safety, gradually becoming an escalating threat to public health [1]. Current laboratory-based pesticides-analyzing conventional apparatus comprising of chromatography [2] mass spectrometry [3] with satisfactory precision resolution were limited by on-site monitoring. Hence, development convenient sensors for pesticide is grea...

Food safety is a crucial issue; all countries have struggled against pesticides for years. In this study, Polypyrrole (PPy)- and Polyacrylonitrile (PAN)-based non-enzymatic electrochemical sensors were investigated to detect the pesticide propamocarb (PM) in food samples. Under experimental conditions, proposed strategy exhibited high selectivity of disposable PPy-based PAN-based determination ...
