Detection of pesticide residues in fruits and vegetables

Fruits and vegetables are daily essential foods on the people's table and are closely related to our lives. It is normal to apply pesticides to fruits and vegetables to prevent diseases and insect pests. However, due to the general lack of scientific knowledge of pesticides used by users and the one-sided pursuit of output, the fruits and vegetables circulating on the market all have pesticide residue problems to varying degrees. Some smokers abuse all kinds of banned pesticides. The pesticide residues on fruits and vegetables have endangered everyone's health and are also increasingly concerned by the public.


The HGC-24A nitrogen blower can simultaneously check 26 kinds of pesticide residues. The method is simple and easy to operate. The recovery rate of all pesticide samples in this experiment is 85.85% to 108.51%, the relative standard deviation is 0 to 4.79%, and the detection limit is 0.06 ~ 2 ppb, fully in line with national inspection standards.
