Abstract

Wherein, with biological resource mainly of pests, it observes directly and efficiently the pesticide residue on vegetable as combating poison with poison. The social and economic meanings include: A. making reasonable use of natural resource; B. saving water and other source; C. eliminating pest and opposite danger; D. guaranteeing people health, improving life quality; E. putting an end to different pesticide residue as well as improper operation methods; F. holding vegetable nutrition. The experiences during two years show this invention is clear and effectively.

Description

The quick biological determination of vegetable residual pesticide

The present invention relates to safety detection, is a kind of biotechnology green screen aspect the persticide residue monitoring

Vegetables are popular food, and remains of pesticide is the problem of popular headache on the vegetables, steep the residual hazard that this not only can not eliminate dish leaf deep layer with a large amount of water loggings, especially the nutrition on the green vegetable has been lost, therefore, monitoring remains of pesticide on the vegetables quickly and easily, make citizen be able to eat quality-assured vegetables, is of the present invention one big characteristics.

As everyone knows, remains of pesticide is fuzzy concept on the vegetables because pesticide variety is various, the character complexity, have on the current social a kind of price very expensive resemble test paper, one monitoring means because one, cost is too high, citizen are difficult to bear; Its two, the monitoring limited by scope, and can not take a sample test wide spectrum be difficult to admittedly the popularization.

And as how one become and to answer ten thousand changes, guarantee health best monitoring means safe against all possibilities, be a kind of bion kind that the present invention adopts.She adopts with harmful system evil, with the harmful advanced person's of evil gram biological monitoring technology.We know that mosquito Fig. 1 is a kind of people and animals' public enemy, inhale the blood that people and animals are arranged in its body, not only have the slim and graceful ability of circling in the air, and have the sensitivity of identification, because its feeding habits are blood, demoting of grain is scarce so it is never worried.Everywhere is grain, is the amusement world everywhere, has the place of procreation not have again under the situation of natural enemy everywhere, and unlimited the breeding formed the public hazards of all people and animals on the earth.The present invention makes test-strips testing cassete Fig. 2 so that promote a conception of species with the mosquito that lives, and combats poison with poison, and two negatives make a positive, drives society, so that form a kind ofly to catch the business activity of mosquito alive, makes mosquito form new view-a kind of making profits, and surveys poison, profitable benign cycle.The survival rate of mosquito is with volume size, and the permeability aspect is different and different, and in general survival rate is greatly about 6 hours-60 hours.Do surviving the mosquito testing cassete, one does not lack the mosquito source, need not raise with wild mosquito, extremely low without the feeding cost.Two mosquitoes suck human blood and spread disease and also contain DNA more or less, to the tolerance level of remains of pesticide than the mankind a little less than, test in life is when at 12 square metres house igniting mosquito-repellent incense, when at 1-3PPM (0.25% rich d-allethrin) under the smog, mosquito is that mobility begins to reduce, and mosquito has lost the ability of existence (because the example in the life is more penetrating, with water smoke and this concentration, effect is identical when 30PPM.) this has only used harmful agricultural chemicals such as never containing DDT, existing big effect.So the test vegetable residual pesticide, testing that with mosquito is to have to ask the thing that must win.

Present technique comprises that a testing cassete Fig. 2 and a basin are soaked with the water of vegetables, new fresh and alive mosquito.Have vaporificly in the testing cassete, keep the drop (little contain rare honey) of mosquito life.After testing cassete is gone in the water cutting of soaking vegetables, whether contain remains of pesticide and promptly come out, the time, mosquito lived promptly nontoxic at 5 minutes, and it is promptly poisonous to die, extremely low with this method cost, greatly on the reduction 0.3-0。5 jiaos, can detect by 5-100 jin vegetables.

Because present technique is innovation, existing domestic in the world all do not have relevant permission to authenticate.Whether the authentication guiding principle with present technique can determine domestic Valuation Standard, is still waiting time with checking

This project has rationally utilized natural resources to establish, and can protect the environment and the ecologic equilibrium, and using water wisely need not be soaked vegetables again, reduces the nutrition leak of vegetables.Biological seizure forms to circulate benignly to change has good start to improving the civic fitness.This project has been passed through the evaluation of national departments concerned.

(Fig. 1 is the vertical view of the testing cassete of interior survival mosquito, and Fig. 2 shows the vertical view of the bleeder vent on the testing cassete transparent plastic case, and Fig. 3 be the side view of testing cassete, therefrom as can be seen little of the case extension be the handle of handling knob.)

Claims

Because present technique is the quick biological determination of remains of pesticide poison, and should biology be exactly day and night to bother the people especially in the summer of scorching hot summer weather, the insect that make troubles and threaten to life and health autumn.

Come toxicity to remains of pesticide with it, defying the law truly has 4 two groups of very heavy magical effects of getting twice the result with half the effort

Just can know that this dish can be eaten in 5 minutes, as long as the testing cassete that mosquito is housed of putting on airs one inserted in the basin that soaks vegetables, how succinct and make things convenient for.

This method here needs protection is mosquito alive in testing cassete and the testing cassete, the more important thing is that protection forms testable method with these.
