Can't generalize! Some pesticides are highly toxic to people, and some pesticides are non-toxic to people! Pesticides are now developing towards environmental friendliness, more and more of them are low or even no harm to the environment, and the same is true for personal safety, some biological pesticides and plant-derived pesticides are more and more, and most of these pesticides are not harmful to human health.

In recent years, scientists have found that the most obvious period of pesticide harm to the fetus is the early pregnancy. It is also the period of occurrence of fetal organs. If pregnant women are often in contact with pesticides during this period, pesticides can enter the pregnant woman's body from the **, respiratory tract, digestive tract and other routes, and then enter the fetus through the placenta with blood circulation.
This can not only cause anencephaly, defects, malformations, mental retardation, stunted growth, and congenital cancer, but also cause fetal growth to stop and cause miscarriage, premature birth, stillbirth, and fetal leukemia. For example, pesticides such as cilisheng and silisan enter the body of pregnant women, which will cause damage to the fetal nerves.
Breastfeeding mothers wearing work clothes stained with pesticides can also cause leukemia in their babies. It has been identified that benzene derivatives in pesticides can cause chromosomal aberrations or mutations, which can disrupt the hematopoietic system, resulting in mutations in white blood cells that cause leukemia, i.e., blood cancer. Experts have also found that pesticides can enter the breast milk after entering lactating mothers through different routes.
Due to the obvious metabolism and other changes in the body of the lactating mother, the concentration of some pesticides in breast milk is very high. However, due to weak disease resistance, imperfect development, and poor detoxification and detoxification function of infants, it is very easy to be poisoned when eating milk containing pesticides. In particular, organophosphorus pesticides (dimethoate, dichlorvos, trichlorfon, methamidophos, etc.) are particularly sensitive to infants, and poisoning can occur even if they are touched or inhaled in small amounts.
During menstruation, women's disease resistance decreases, the brain responds sluggishly, the body's capillary permeability increases, blood vessels dilate, and contact with pesticides can easily make pesticides enter the body from different ways, endangering health.
Since pesticides are very harmful to women, it is advisable for women not to be exposed to pesticides. If you come into contact with pesticides, you must do a good job of protection. Do not let pesticides come into contact with **, and their work clothes should be cleaned in time.
Pesticides in the family should not be placed casually, there should be a special warehouse, powder pesticides should be strictly bandaged, to prevent the powder from polluting the environment, or being blown away by the wind. Liquid pesticides should be capped to prevent volatilization and inhalation. Fields that have been sprayed with pesticides are strictly forbidden for women to enter.
Pesticides in the home should not be used in excess.

1. Acute poisoning, pesticides enter the human body in large quantities through mouth, inhalation or exhalation, and the acute pathological reaction shown in a short period of time is acute poisoning. Acute poisoning often leads to nerve paralysis and even death, and even causes large-scale death, becoming the most obvious pesticide hazard. According to the World Health Organization and the United Nations Environment Programme, more than 3 million people worldwide are poisoned by pesticides each year, of which 200,000 die.
2. Chronic hazardsLong-term contact with or consumption of food containing pesticide residues can make pesticides accumulate in the body and pose a potential threat to human health, that is, chronic poisoning, which can affect the nervous system, destroy liver function, cause physiological disorders, affect the reproductive system, produce deformed freaks, and lead to cancer.

I would add that the use of pesticides will accelerate the evolution of pests, strengthen their resistance, and may even produce pests that cannot be eliminated with pesticides in the future.
Organisms should be used to control pests.

The use of pesticides plays an important role in agricultural production, but it also poses a threat to human health. To determine which pesticide is most harmful to humans, there are many factors to consider, such as toxicity, dose, and route of inhalation or exposure.
First of all, from the perspective of toxicity, organophosphorus pesticides are the most likely to cause harm to the human body. Organophosphorus pesticides are very toxic, and if they are ingested or ingested by mistake, they will affect the human nervous system, causing coma, poisoning and even death. Moreover, the toxicity of organophosphorus pesticides can also remain in crops or the environment, so eating agricultural products containing organophosphorus pesticides will increase the burden of toxins in the human body.
Secondly, consider the harm of the dose to the human body. The higher the dose, the more harmful it is, so the pesticides used in large quantities are even more dangerous. For example, the herbicide glyphosate (glyphosate) has very low toxicity, but it can also cause harm to the human body if used in too large amounts.
Therefore, when using pesticides, it is not only necessary to use them in strict accordance with the dosage, but also to pay attention to reasonable application methods.
Next, consider the route of exposure. The harm of pesticides is not only reflected in food, but also the harm to the human body from exposure to pesticides cannot be ignored. For example, it is best to wear protective equipment when using chloropropanol ester pesticides to prevent exposure to hazards.
Similarly, do not wash your hands directly with water after contact with pesticides, but soak your hands in dilute alkaline water or salt water.
In summary, organophosphorus pesticides are the most harmful to humans, but other types of pesticides also have risks. When using pesticides, we must use them in strict accordance with the instructions and master good use methods to avoid the risk of harming the human body to the greatest extent. At the same time, it is important to ensure the safety of the food, and if you have doubts when buying food, it is best to choose organic food or buy it from a reliable farmer or merchant.
There are high and low levels of noise. Low-intensity noise is generally not harmful to people's physical and mental health, and in many cases it is also beneficial to improve work efficiency. The high-intensity noise mainly comes from industrial machines (such as looms, lathes, air compressors, pickaxes, blowers, etc.), modern vehicles (such as cars, trains, motorcycles, tractors, airplanes, etc.), loudspeakers, construction sites, and the noise of shopping malls, sports and entertainment venues. >>>More
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. >>>More

First of all, high blood pressure is not terrible, but it is terrible to cause complications. If you have long-term high blood pressure and poor blood pressure control, it will cause complications such as heart, brain, kidney, and fundus. In detail, it generally causes cerebrovascular disease, hypertensive heart disease, hypertensive nephropathy and fundus lesions, so after being diagnosed with hypertension, it is necessary to adhere to regular oral antihypertensive drugs for a long time under the guidance of professional doctors, and must control blood pressure within the normal range.
