Some vegetables are honored as “the silt not to dye”, but fact if so? The expert pointed out regarding this that the factory mine’s waste material dregs can the contaminated soil, the waste water be able to pollute the water source, the waste gas can pollute the atmosphere. But the vegetables and all plants are the same, needs to absorb in the soil, the atmospheric nutrients in the growth. Therefore, the factory mine’s deleterious substance can finally discovered in the nearby vegetables and the crops. Even if the crops are far away from the factory mine, in the agricultural production employs the chemical fertilizer and the agricultural chemicals also possibly cause the vegetables pollution.

　　According to research, because root absorbancy is strongest, radical class vegetables like Gan Shu, the radish, the carrot, the lotus root and so on are most sensitive to the soil and the water source pollution. They (seedling) grow up gradually from a seed, mainly depending on absorption periphery in soil material, therefore does not have so-called “the silt does not dye” the myth.

　　The eggplant fruit class vegetables like green pepper, the tomato and so on, the tender pod class vegetables like cowpea and so on, as well as bulb class storage contaminating materials and so on vegetables like onion, garlic, onion are few. However, if the cultivation environment’s pollution degree is serious, regardless of then any variety’s vegetables difficult to run away the destiny which pollutes.

　　Therefore, the consumer wants to learn the recognition to have the pesticide residue or the hormone urge steadily the vegetables. The following three simple choice vegetables method might as well studies one study.

　　First, does not buy the shape and the color unusual vegetables. The unusual vegetables possibly have processed with the hormone. If fragrant-flowered garlic, when its leaf is specially spacious, plump, when must extend 1 time compared to the general width leaf fragrant-flowered garlic, possibly has used the hormone in the cultivation process. Some vegetables color is not normal, like the vegetable leaf loses the ordinary green to assume the jasper deep green, the young soy beans exceptionally waits, they possibly spray before the recovery or have soaked the methylamine phosphorus agricultural chemicals, is not suitable selects and purchases.

　　Second, little buys the multi-insect vegetables. In the numerous vegetables, some vegetables by the harmful insect institute “the favor”, for instance the green vegetables, the cabbage, the cabbage, the cauliflower and so on, they are the multi-insect vegetables easily. Because the insect pest are many, some growers to their spraying, this easy to cause the pesticide residue frequently. Some vegetables insect likes eating not greatly, like chrysanthemum coronarium, greens, celery, carrot, onion, garlic, fragrant-flowered garlic, green onion, coriander and so on, might as well multi-choice choice.

　　Third, does not buy the quantity fertilizer big vegetables. Because the chemical fertilizer is specially the nitrogenous fertilizer (for example urea, ammonium sulfate and so on) the employment quantity is oversized, will cause the vegetables the nitrate pollution to be quite serious. The going on the market vegetables test result indicated that the nitric acid salt content from to the weak arrangement is: Root vegetable class, Chinese yam class, green edible herb, cabbage class, onion garlic class, legumes, melon class, eggplant fruit class, edible fungi. Their nitric acid salt content height may differ 10 times. Therefore we should eat a melon, the fruit, the bean and the edible fungus as far as possible, like cucumber, tomato, young soy beans, shiitake mushroom and so on.
