What is the harm of excessive pesticide residues to people

Pesticide residues are extremely harmful. Pesticide residues in fruits and vegetables have posed a serious threat to the health of consumers. According to experts, the poisoning caused by pesticides can be divided into acute and chronic, acute poisoning can show symptoms of poisoning within 24 hours, mainly manifested as muscle spasms, nausea, vomiting, diarrhea, vision loss and dyspnea.

It is understood that tens of thousands of people are poisoned by pesticides every year, and thousands of people die, most of whom are caused by excessive pesticide residues in vegetables. Chronic pesticide poisoning is generally not easy to detect, because pesticides have a process of accumulation in the body, and even if they show symptoms of poisoning, because some symptoms are similar to general headaches and tiredness, they are often ignored by people, and once they are discovered, it is too late. Not only that, experiments have confirmed that pesticides have teratogenic and carcinogenic effects on the human body, and relevant epidemiological investigations have showed:

The incidence of malignant tumors has increased year after year, and the pesticide residues in vegetables are not unrelated, pesticide residues as toxic substances have enough power to change genetic genes, resulting in fetal malformations, this force is far greater than the harm of tobacco and alcohol, and the malformation rate of fetuses in China is still about 3 to 5.

Pesticides are a special class of chemicals, which can not only prevent and control agricultural and forestry pests and diseases, but also cause harm to humans and animals, and destroy the environment on which human beings depend. According to the literature, the utilization rate of pesticides is generally 10%, and about 90% of pesticides remain in the environment, causing environmental pollution. A large number of lost pesticides volatilize into the air, flow into the water body, settle and accumulate in the soil, pollute the agricultural, livestock, fishery and fruit products, and transfer to the human body through the enrichment of the food chain, causing harm to the human body.

There are different degrees of pesticide residues in all countries in the world, and pesticide residues can lead to the following hazards.

These will be dissolved by the moisture in the soil as fertilizer, and the plants will turn it into essential elements for absorption, so it is recommended not to worry, it will not cause human poisoning.

1. Use water to rinse and soak most pesticides are acidic, as long as you use slightly alkaline rice washing water or detergent, you can remove most of the pesticides, but do not break the vegetable leaves in the washing process, otherwise it will lead to secondary pollution in the vegetable leaves. Most pesticides are water-soluble, generally on the surface of vegetables, as long as they are cleaned well, the surface of the pesticide can be cleaned.

2. When eating vegetables, you can peel off the skin, many vegetables have the most pesticides attached to the outermost leaves, and the skin can be peeled off to avoid the risk of eating pesticides. You can use hot water to scald, blanch the vegetables in hot water for about two minutes, and then rinse them twice with clean water to remove 90% of the residual medicine.

3. You can add salt and clean it, such as cucumbers or tomatoes and other vegetables after cleaning if I still don't feel at ease, you can put salt on the cutting board, gently turn the cucumber or tomato on the salt with your hands, and then wash off the salt with water, so that the pesticide on the cucumber can be washed off.

Pesticide residues are very harmful to the human body and can lead to many serious health problems.

First of all, pesticide residues can have a toxic effect on the nervous system of the human body, which may cause symptoms such as headaches, nausea, muscle aches, and mental disorders. Secondly, pesticide residues can have a toxic effect on the body's immune system, which may lead to immune dysfunction, which can lead to many diseases, such as pneumonia, hepatitis, nephritis, etc. In addition, pesticide residues can also have a toxic effect on the human digestive system, which may cause symptoms such as indigestion, diarrhea, and abdominal pain.

In addition, pesticide residues can also have toxic effects on the human reproductive system, which may cause symptoms such as infertility, premature birth, and miscarriage. Pesticide residues can also have toxic effects on the human blood system, which may cause symptoms such as hemoglobin reduction, thrombocytopenia, and blood clotting disorders. In addition, pesticide residues will also have toxic effects on the human body's first system, which may lead to ** disease, dermatitis, rash and other symptoms.

In short, pesticide residues are very harmful to the human body and may lead to many serious health problems, therefore, effective measures should be taken, such as controlling the amount of pesticide use, improving the pesticide management system, strengthening the monitoring of pesticide residues, etc., to reduce the harm of pesticide residues to the human body.

Pesticide residues refer to the phenomenon that after the application of pesticides in agricultural production, a part of the pesticides directly or indirectly remains in grains, vegetables, fruits, livestock products, aquatic products, and soil and water bodies. The main reason is that the pest control method is single and the structure of pesticide products is unreasonable.

The root cause of reducing the harm of pesticide residues is the rational use of pesticides.

First, fruit and vegetable salt.

Fruit and vegetable salt is specially made for the production of fruits and vegetables. Its main ingredients are special salt, sodium citrate, and some surfactants, etc., which are relatively safe to use, and the actual effect of removing pesticide residues is also very good. At present, there are a few pieces of a packet of fruit and vegetable salt on the market, ranging from tens to thousands of yuan.

If it's not a little bit cheaper, you can buy it back and try to apply it. After all, when you eat the items in your stomach, you still have to eliminate the residual fertilizer.

Second, fruit and vegetable machine.

Compared with fruit and vegetable salt, the fruit and vegetable machine is a more intelligent system, which is designated for disinfection and sterilization on time, and it is relatively safe and secure when applied. Generally speaking, the fruit and vegetable machine uses ozone sterilization, which can quickly remove pesticide residues on the surface of fruits and vegetables. In addition, the sterilization rate of Escherichia coli and Streptococcus aureus on fruits and vegetables can reach more than 99%.

There are many sterilization effects, and the natural price is not cost-effective. If the economic development of the family allows, why not buy a safe house reserved. In one hand, peace of mind.

Third, wash rice water.

Rice washing water is the most common way to remove pesticide residues on the surface of fruits and vegetables, and it is economical to use, but the actual effect is not as ideal as fruit and vegetable salt and fruit and vegetable machines. Generally speaking, the removal of fruits and vegetables with 30 minutes of soaking in rice washing water is only about 60%. It is not possible to completely remove pesticide residues, and it is relatively time-consuming.

If some people don't want to eat rice, they may not even be able to wash rice. It is precisely because of this that fruit and vegetable machines and fruit and vegetable salt will be used to replace rice washing water.

( ) China has always been a big agricultural country, so relatively speaking, in order to maintain food production, the use of pesticides is more, so the harm caused by pesticide pollution is relatively serious, so what are the specific harms of pesticide pollution?

The pesticides that cause pollution are mainly organochlorine pesticides, metal preparations containing lead, arsenic, mercury and other substances, and some specific herbicides.

The loss of pesticides into the environment will cause serious environmental pollution and sometimes even extremely dangerous consequences.

Polluting the air and water environment, resulting in soil compaction.

The pesticides lost to the environment are evaporated and transpired into the atmosphere, and the fluttering pesticides are adsorbed by the dust in the air. and spread with the wind. Cause pollution of the atmospheric environment.

Pesticides in the atmosphere, through rainfall, these pesticides flow into the water, thus causing pollution of the water environment, causing harm to people, animals, especially aquatic organisms (such as fish and shrimp). At the same time, pesticides lost to the soil can also cause soil compaction.

Enhance the resistance of germs and pests to pesticides.

Using the same pesticide for a long time will eventually enhance the resistance of germs and pests. In the future, the prevention and control of the same kind of bacteria and pests must continue to increase the dosage of pesticides, otherwise the purpose of eliminating bacteria and pests cannot be achieved. A vicious circle is formed.

Kills beneficial organisms.

The vast majority of pesticides kill a variety of organisms without selectivity, including organisms that are beneficial to people, such as frogs, bees, birds, and earthworms. The reduction or extinction of these beneficial insects and birds actually reduces the natural enemies of pests, which will lead to an increase in the number of pests and affect agricultural production.

Poisoning of wildlife and livestock.

Eating food contaminated with pesticides can cause acute or chronic poisoning by wildlife, livestock and poultry. The most important thing is that pesticides affect the reproductive ability of organisms, such as many birds and poultry due to the influence of pesticides, the weight of the eggs is reduced and the eggshells are thinned and easily broken. The extinction of many wildlife species is directly related to pesticide pollution.

In addition, chronic poisoning caused by the accumulation of a small amount of pesticides in the human body cannot be ignored. Pesticide contamination has caused many public hazards. Many have banned the use of pesticides such as ddt, dieldrin, chlorine preparations, etc., and actively develop and produce low-toxicity and high-efficiency pesticides, while paying attention to the scientific use of pesticides, vigorously advocating biological control, protecting beneficial birds and insects, and achieving "treating insects with birds" and "treating insects with insects".
