A fast, simple, and easily automated method for the determination of two insecticides, diazinon and deltamethrin, and two fungicides, iprodione and prochloraz, in mushroom cultivation compost samples, based on selective pressurised liquid extraction (SPLE) and gas chromatography coupled to tandem mass spectrometry, is presented.
The proposed method integrates extraction and clean-up processes in one single step, by adding a clean-up sorbent into the extraction cell.
SPLE variables were thoroughly studied by experimental design.
First, different clean-up sorbents and extraction solvents were screened at two temperature levels using a multifactor design; resulting Florisil and 1 : 1 acetone-dichloromethane the best combination.
Then, temperature, extraction time, and sample-sorbent mass ratio were optimized by a central composite design.
Best recoveries were obtained with a 0.4 sample-sorbent ratio, at 105°C and a 2 min extraction time.
The SPLE method was characterized in terms of recovery (with values ranging from 81 to 103%), repeatability and intermediate precision (showing relative standard deviations less than 12% in most cases), and sensitivity (providing detection limits between 0.1 and 6 ng mL–1).
However, in spite of the clean-up process a matrix effect was observed and therefore standard addition calibration was recommended.
