Pesticide is a double-edged sword. If it is used properly, it can reduce the production of food and fruits and vegetables. If it is used improperly, the residue will be too high, which will bring hidden dangers to people's health. So how do people identify high residual fruits and vegetables? First, most of the abnormal shape and color are high residual fruits and vegetables. Vegetables of normal shape and color are generally cultivated by conventional methods and have not been treated with chemicals such as hormones, while abnormal vegetables may have abused pesticides and chemical fertilizers. Second, do not buy more insects vegetables. Among the many vegetables, some vegetables are susceptible to insect pests, which are easily favored by insects. They can be called multi-worm vegetables; they are less liked by some vegetables and insects. They can be called worm-eaten vegetables. This is due to the specificity of different components and odors of vegetables. decided. Among the many insect vegetables, there are mainly vegetables, Chinese cabbage, cabbage, cauliflower, and so on; the lesser insect vegetables include garland chrysanthemum, lettuce, celery, carrot, onion, garlic, leeks, green onions, parsley, and the like. Due to the large number of pests, many insects have to be sprayed and controlled regularly, which is bound to form pesticide residues. In order to avoid excessive intake of pesticides, you should choose to eat less worm-eaten vegetables in peacetime. We usually see more wormholes in vegetables, as if we have not played drugs and eat this dish safely. In fact, this is unreliable. Third, do not buy vegetables with a large amount of fertilizer. Due to the large amount of chemical fertilizers, especially the excessive application of nitrogen fertilizer (such as urea, ammonium sulfate, etc.), it will cause nitrate pollution of vegetables. Nitrate itself is not very toxic, but it will be reduced to nitrous acid as the vegetables enter the gastrointestinal tract. Nitrous acid is then combined with secondary amines in the gastrointestinal tract to form nitrosamines, a carcinogen. We should eat as much as possible melon, fruit, beans and edible fungi, such as cucumbers, tomatoes, green soybeans, mushrooms and so on. However, these measures are also artificially identified. It is often impossible to judge whether pesticides are contained in fruits and vegetables with the naked eye. Now generally use pesticide residue detector to quickly determine whether there are pesticide residues in fruits and vegetables. Its light source uses light-emitting diodes, which have the advantages of energy saving, environmental protection, power saving, long life, and fast response. The pesticide residue detector has no mechanical moving parts, anti-interference, anti-vibration, and stable and reliable performance. This instrument has high sensitivity, and the minimum detection limit for methamidophos, dichlorvos and other pesticides is better than the national standard requirements. It is more accurate and faster than manual recognition.
