Rapid and sensitive determination of the prochloraz residues in the cultivated mushroom, Agaricus bisporus (Lange) Imbach

Abstract

The QuEChERS (quick, easy, cheap, efficient, rugged, and safe) sample preparation method and gas chromatography-electron capture detector (GC-ECD) were adopted for rapid extraction and determination of prochloraz residues in cultivated mushrooms. The results were further confirmed by using a gas chromatography-mass spectrometry (GC-MS) system. The method showed that there was a good linear relationship with a correlation coefficient of r 2 ¼ 0.999 in the concentration ranges from 52.9 to 1000 mg L À1 . The limit of detection (LOD) of the GC-ECD method was 15.9 mg kg À1 and the limit of quantification (LOQ) was 52.9 mg kg À1 . The data satisfactorily demonstrated the good repeatability of the method with relative standard deviations (RSDs) lower than 20%. The recovery values for spiked mushroom samples were 100.6 AE 1.6% and 105.6 AE 3.9% for 250 and 1000 mg kg À1 , respectively. The samples from seven different mushroom growing facilities were analyzed. The residue levels of prochloraz ranged from <LOQ to 105.4 AE 16.9 mg kg À1 . Although, this was the first study on determination of prochloraz residues in mushroom samples by GC-ECD after QuEChERS extraction, the adopted method adequately met the validation criteria and was successfully applied to analyze prochloraz residues in the mushroom samples. Therefore, this method could be regarded as a new alternative for routine analysis of trace levels of this most commonly used pesticide in mushroom production.

Method development and validation of ten pyrethroid insecticides in edible mushrooms by Modified QuEChERS and gas chromatography-tandem mass spectrometry

“…In recent years, the QuEChERS methodology has been develpoed as a very popular method to determine pesticide residues in all kinds of food matrices [23][24][25][26][27][28][29] . And there are some papers that applied QuEChERS for the extraction of pesticides from mushrooms and determination of residue used GC, GC-MS/MS 30,31 , or LC-MS/MS 10,11 . However, simultaneous determination of pyrethroid residues in mushrooms by GC-MS/MS has not been reported.…”

Modelling of CSTR Flow Field for Agaricus bisporus Residue Fermentation Based on CFD Numerical Simulation

“…Appropriate treatment could make the residues to be energy resources and environmentally friendly (Bentsen et al 2018). Agaricus bisporus residue is a mixture of residual fungus substrates and metabolites after Agaricus bisporus harvest (Cengiz et al 2014). Due to the abundant nutrients in the residue, can be used as raw material for anaerobic fermentation to produce biogas.…”

“…However, at the same time, prochloraz has been suspected of acting as an endocrine disrupter [ 17 , 18 ]. It is widely used on fruits and vegetables to prevent deterioration during storage [ 19 , 20 ]. However, prochloraz residue on agricultural products may pose a risk to human health and environmental safety [ 21 , 22 ].…”
