How to identify pesticide residues in vegetables

When people buy vegetables, they are always very concerned about whether the pesticides exceed the standard and whether the soil planted has been contaminated. Is there any way to help us identify them? Some studies have pointed out that because the root has the strongest absorptive capacity, root vegetables such as sweet potato, radish, carrot and lotus root are most sensitive to soil and water pollution. On the other hand, eggplant fruit vegetables such as green peppers and tomatoes, tender pods vegetables such as beans, and bulb vegetables such as onions, garlic and onions store less pollutants. However, if the pollution of the cultivation environment is serious, then no matter what kind of vegetables can not escape the fate of pollution. Therefore, consumers should learn to identify vegetables that have pesticide residues or hormone growth.

Don't buy vegetables with abnormal shape and color.

Abnormal vegetables may have been treated with hormones. Such as leek, when its leaves are particularly broad and thick, twice as wide as the general broad-leaf leek, hormones may have been used in the cultivation process. The color of some vegetables is also abnormal, such as vegetable leaves lose their usual green and show dark green, edamame beans are green abnormally, they may be sprayed or soaked in methamidophos pesticides before harvest, so they should not be purchased.

Buy fewer wormy vegetables

Among the many vegetables, some vegetables are easily "favored" by pests, such as green vegetables, Chinese cabbage, cabbage, cauliflower and so on. Due to many insect pests, some growers will often spray them, which can easily lead to pesticide residues. Some vegetable bugs do not like to eat, such as chrysanthemum, lettuce, celery, carrots, onions, garlic, leeks, green onions, coriander and so on.

Do not buy vegetables with a large amount of fertilizer

Due to the excessive application of chemical fertilizer, especially nitrogen fertilizer, the nitrate pollution of vegetables is more serious. The detection results of listed vegetables showed that the order of nitrate content from strong to weak was root vegetables, potato, green leafy vegetables, cabbage, onion and garlic, beans, melons, eggplant fruits and edible fungi. Their nitrate content can be 10 times different. So we can choose to eat more melons, fruits, beans and edible fungi, such as cucumbers, tomatoes, edamame beans, mushrooms and so on.
