Description
Technical field
The utility model is related to technical field of bioengineering, more particularly to a kind of cover buckle formula organic phosphates and carbamate
Pesticide residue rapidly measuring device.
Background technology
Pesticide is one " double-edged sword ", on the one hand, pesticide must be indispensable in agricultural modernization, is reducing crop disease
Insect pest increases agricultural output, promotes agricultural product quality etc. and has played huge effect.On the other hand, since people exist
Unreasonable and overdose uses chemical pesticide during preventing diseases and pests of agronomic crop, causes the persticide residue in agricultural product more next
It is higher, the outlet of agricultural product and the health of the people are affected, agroecological environment is also destroyed.
Green peace organization in 2009 purchases vegetables simultaneously in the large supermarket on three ground of Beijing, Shanghai and Guangzhou and the market of farm produce
Inspection is found：In the vegetable sample of 45 inspections, there are 40 to detect pesticide residue；Pesticide variety is up to 50 kinds, wherein 5 kinds
It is the high-toxic pesticide that the World Health Organization confirms；The 29-1 months in January, 2013 Guangzhou on the 31st Jiangnan food market detects and destroys ordeal bean
(contain disabling high-toxic pesticide " carbofuran ") in 13.04 tons of angle；On September 2nd, 2017, People's Daily report more than the 100 of Shandong Shouguang
Sheep is dead after edible raiser gets the big Folium Allii fistulosi come back from freezer, and local health quarantine station is found that taboo in problem Folium Allii fistulosi
With farm chemical ingredients thimet.It can be seen that Pesticide Residue has become a food-safety problem to become increasingly conspicuous.
Conventional pesticide residue analysis method such as liquid chromatography (HPLC), gas chromatography (Gc), mass spectrum (Ms) method etc.,
That there is sample pre-treatments is complicated, instrument and equipment is expensive, the time-consuming length of analysis, requires those skilled in the art that could complete etc. to ask
Topic.Since these methods cannot meet the requirement that sample site quickly detects, people is forced to be gone out with new principle and method
Send out high specificity, high sensitivity, convenient and efficient, accurate safe New Technique for Fast.
