The method provides for rapid detection of trichlorfon, profenofos, methomyl, carbofuran and dichlorvos residue in vegetables such as rape, spinach, celery, leek and so on.

The enzyme inhibition (rate) method (spectrophotometry) performance indicators are as follows:

Detection limit: trichlorfon 0.1 mg / kg, profenofos 0.5 mg / kg, methomyl 0.2 mg / kg, carbofuran 0.02 mg / kg, dichlorvos 0.2 mg / kg.

Sensitivity: Sensitivity ≥95%

Specificity: Specificity≥85%.

False negative rate: False negative rate≤5%.

False positive rate: false positive rate≤15%.

  

Test card method performance indicators are as follows:

Detection limit: trichlorfon 0.1 mg / kg, profenofos 0.5 mg / kg, methomyl 0.2 mg / kg, carbofuran 0.02 mg / kg, dichlorvos 0.2 mg / kg.
