Can you eat vegetables with heavy metals in the land?

Can't eat! The hazards of excessive heavy metals in farmland soil.

1.Harm to the soil itself: after a large number of heavy metals enter the soil, they cannot be degraded, and it is difficult to move out of the soil, and they will accumulate more and more, and the content will gradually increase, which will have obvious adverse effects on the physical and chemical properties of the soil, soil biological characteristics and microbial community structure, and destroy the ecological structure and function of the soil.

2.Harm to crops: Too much heavy metals in the soil will bring direct harm to crops and lead to the death of plants; Under the stress of heavy metals, it sometimes affects the absorption of nitrogen, phosphorus and potassium nutrients by crops, inhibits crop growth, and causes the yield of agricultural products to decline. In addition, due to soil heavy metal pollution, the content of heavy metals in agricultural products can increase, resulting in pollution of agricultural products and threatening the quality and safety of agricultural products.

3.Hazards to human health: Contaminants such as heavy metals in the soil can pass through various food chains.

Through graded bioaccumulation, it is harmful to human health, and can also indirectly pose a threat to human health by affecting the quality of water and atmospheric environment.

The land contains heavy metals, and vegetables cannot be eaten.

Not only can't you eat vegetables, but you can't eat other crops.

Such vegetables and grains are heavy metals that exceed the standard.

It's best not to eat, the land contains heavy metals, and the vegetables you grow also contain heavy metals, and eating too many heavy metals is too harmful to the human body.

Some land contains heavy metals that exceed the standard, and you can eat and eat vegetables, you don't look at him as over-standard, as long as it does not affect the vegetables, the vegetables are the same as people, and you can do it if you have more, and you can not absorb it.

It depends on the content, and in the case of a dose lower than the standard, it can still be eaten, depending on what kind of heavy metal it is. But it is best to eat less, as heavy metals will accumulate in the body and will be difficult to remove.

Summary. Hello, happy to answer for you. Can you eat vegetables grown on land containing heavy metals:

Can't eat! Harm to the soil itself: After a large number of heavy metals enter the soil, they cannot be degraded, and it is difficult to move out of the soil again, and they will accumulate more and more, and the content will gradually increase, which will have obvious adverse effects on the soil physical and chemical quality, soil biological characteristics and microbial community structure, and destroy the ecological structure and function of the soil.

Too much heavy metal in the soil will bring direct harm to crops, leading to the death of plants. Under the stress of heavy metals, it sometimes affects the absorption of nitrogen, phosphorus and potassium nutrients by crops, inhibits crop growth, and leads to the decline of agricultural product yield. In addition, due to soil heavy metal pollution, the content of heavy metals in agricultural products can increase, resulting in pollution of agricultural products and threatening the quality of agricultural productsHarm to human health: Heavy metals and other pollutants in the soil will be harmful to human health through various food chains and through gradual bioaccumulation, and can also indirectly pose a threat to human health by affecting the quality of water and atmospheric environment.

Among these vegetables containing heavy metals, water spinach should have a high reputation, and it is called a vegetable with "strong metal absorption" and "zuidu" by netizens. In order to achieve the best results, the relevant investigators purchased a total of 10 samples of water spinach, leeks, spinach, celery and amaranth from supermarkets and farmers' markets, and sent them to the relevant testing centers for testing of five heavy metals including lead, arsenic, mercury, cadmium and chromium.

Summary. What is better to plant in land with excessive heavy metals: Hello dear, if the heavy metal content in the land exceeds the standard, what crops are better to plant need to consider a variety of factors, such as the type of heavy metals, the degree of exceedance, soil properties, planting requirements, economic value, etc.

Generally speaking, the following crops are more suitable for planting on land with excessive heavy metals:1Goji Berry:

Goji berries have deep roots and thick stems, strong adaptability, can resist drought, cold, diseases and pests, and wolfberry can grow in acidic, alkaline, sandy and heavy metal excess land, not easy to be polluted. In addition, goji berries have a high economic value. 2.

Farming: such as fish farming, earthworms, etc., these crops do not need to be planted, but through breeding and other ways to use waste land. It is basically not affected by heavy metals, and at the same time, economic benefits can be obtained.

3.Mushrooms: such as oyster mushrooms, enoki mushrooms, etc., these fungi have a strong absorption effect on the environment and pollutants, and can reduce the content of heavy metal pollutants in the soil.

4.Rice: Rice grows in a special environment that requires a lot of water and nutrients, while being able to absorb and stabilize heavy metal pollutants in the water and fix them in the soil.

It should be noted that while planting suitable crops, effective soil remediation measures should also be carried out, and the soil should be monitored regularly to ensure that crops grow safely.

Harm to human health: Heavy metals and other pollutants in the soil will be harmful to human health through various food chains, through gradual biological suffocation and enrichment, and can also indirectly pose a threat to human health by affecting the quality of water and atmospheric environment. <>

Summary. The presence of heavy metals in the soil may have a negative impact on plant growth and human health. If the heavy metal content in the soil exceeds the safety standards set by the state and local governments, then the vegetables grown may be harmful to human health and are not recommended to be eaten.

Therefore, in order to protect human health, it is recommended to choose vegetables from the regular market or supermarket with protection when buying vegetables, and pay attention to the ** of vegetables. If you're concerned about the safety of your home-grown vegetables, you can get a soil test or consult a professional for advice.

Can the land in the metallurgical plant grow vegetables? And some of the soil has iron slag in it.

The presence of heavy metals in the soil may have a negative impact on plant growth and human health. If the heavy metal content in the soil exceeds the safety standards set by the state and local governments, then the vegetables grown may be harmful to human health, and it is recommended not to eat them. Therefore, in order to protect human health, it is recommended to choose vegetables from the regular rubber spring market or supermarket with guarantees when buying vegetables, and pay attention to the best of vegetables.

If you are concerned about the safety of the vegetables grown at Fengnai, you can conduct soil testing or consult relevant professional organizations.

It is not recommended to consume it.

Thank you for your patience and the answers to your questions are as follows. Newly opened alkaline soils are often rich in sodium, carbonates and other minerals, and lack of stimulating organisms and nutrients, all of which can affect crop growth and yield. In addition, if there are high concentrations of heavy metals in the soil, it can also adversely affect the growth and quality of crops.

Therefore, if you want to grow vegetables in newly opened alkaline soil, it is advisable to conduct a soil test to determine if harmful substances such as heavy metals are present in the soil. If the test results show that the soil contains too many heavy metals, it is recommended to take appropriate measures, such as adding organic fertilizers, soil conditioning, and selecting vegetable species with heavy metal resistance, to reduce the adverse effects of heavy metals on the growth of vegetables. In addition, in order to ensure the safety and health of vegetables, it is recommended to wash and cook them thoroughly before eating Li Song to remove harmful substances from the soil.

Vegetables grown on polluted land cannot be eaten, and the vegetables grown in such fields are harmful to the human body.

In order to obtain high-quality and high-yield vegetables, the following aspects should be considered in the selection of vegetable garden soils:

1) Sealing texture: The sealing selection of vegetable plots mainly considers whether the structure of the seal and its physical and chemical development can meet the requirements of vegetable growth and development. Generally speaking, the seal with rich agglomerate structure has good fertilizer retention, water retention and aeration properties, and is most suitable for the growth and development of vegetables.

Therefore, it is more suitable to choose sandy loam, loam and clay loam soil to grow vegetables.

2) Soil pH: The pH value of the soil is a condition that must be considered for vegetable cultivation. Most vegetables are better to grow in slightly acidic and neutral soils, i.e. they still grow in slightly alkaline soils, i.e. the pH is within the range.

Only a few vegetables are more alkali-tolerant, such as spinach, which still grows well in slightly alkaline soils.

3) The level of groundwater level: The level of groundwater level has a direct impact on the growth and development of vegetables. The groundwater level of the soil is too high, so that the root system cannot be extended downward, the aeration is poor, and pests and diseases are easy to spread.

Generally, the groundwater level of vegetable fields should be below 2 meters, and at least below 1 meter, otherwise it is not suitable for planting terrestrial vegetables.

Although pollution is still harmful to the human body in the end, is there any pollution now? Fertilizers and pesticides are harmful.

Of course, you can't eat it, because vegetables are poisonous.
