Description

technical field [0001] The invention relates to the technical field of food safety detection, in particular to a portable pesticide residue detection device and method. Background technique [0002] Organophosphorus and carbamate pesticides have been widely used in the production of agricultural products of fruits and vegetables. However, long-term consumption of agricultural products containing organophosphorus and carbamate pesticide residues is very harmful to human health. Most of the existing detection technologies require the participation of large-scale instruments and professionals, and cannot realize portable detection. Contents of the invention [0003] In view of the above analysis, the embodiment of the present invention aims to provide a portable pesticide residue detection device and method to solve the problem that existing pesticide monitoring devices are not easy to carry. [0004] In one aspect, the present invention provides a portable pesticide residue...
