Judge pesticide residue and its pollution condition, this method is generally as causing agricultural product on-site test of being poisoned；2, chemical analysis,
Chemical detection method for pesticide residue has spectrophotometry, polarography, atomic absorption spectrography (AAS), thin layer chromatography, gas phase
Chromatography, liquid chromatography, isotope-labelling method, nuclear magnetic resonance spectroscopy, application of gas chromatorgraphy/mass method etc., the spirit that these analysis methods have
Sensitivity is not high, the instrument of some need valuableness, also the special equipment of some need；3, the immunoassay of simultaneous biology and chemistry,
Organic phosphorus and carbamate pesticide is nervous system acetylcholine esterase mortifier altogether, therefore can use pesticide target enzymes-
Acetyl gallbladder detects Organophosphorus and carbamate pesticides class pesticide with the suppressed degree of alkali esterase (AChE)；4, biochemistry detection method,
There are radioimmunoassay, EIA enzyme immunoassay, Drug analysis object immunoassay, Immunosensor Analysis etc., because of immunization
Finished product kit is relied on from external import, is not promoted the use of on a large scale.But since pesticide species are more, structure and property are each
Different, residual quantity is very low in fruits and vegetables, and fruits and vegetables complicated component, directly measures extremely difficult, needs thus pair
Sample Pretreatment Technique, analysis determining technology, Fast Detection Technique are improved, develop and are developed.
