Insecticides all contain certain toxicity, which is harmful to human body. Herbicides do not have immediate effects on animals like pesticides, but they can irritate the skin and cause allergies. Inhalation into the respiratory tract can also cause poisoning or teratogenicity. The most famous one is Agent Orange, an efficient defoliant, which is named Agent Orange because its container is marked with orange stripes. During the Vietnam War, the U.S. military used low-altitude and slow-moving planes to spray on forests, jungles and other vegetation that were judged as hiding places for armed men of the Communist Party of China, so that trees and other plants fell leaves. It contains a chemical poison called 2,4,5-T-a dioxin (commonly known as dioxin) compound.
After the Vietnam War, the "sequela of agent orange" gradually appeared, and the Vietnamese people and American veterans who participated in the Vietnam War suffered greatly. Because the content of tetrachlorobenzene and dioxin in their blood is much higher than that of ordinary people, their bodies have various diseases. More seriously, the toxin changed their fertility and genetics. In the Changshan area of Vietnam, people often find some deformed children with missing arms and legs or festering all over, and there are many idiot children. These people are the direct victims of Agent Orange. According to statistics, the rate of birth defects of children who served in the south during the Vietnam War is as high as 30%. In addition, the spontaneous abortion rate of military wives who served in the south is also very high.
Therefore, when spraying this kind of herbicide, strict protection is needed. You must wear long clothes and long sleeves, and you can't expose your skin to the air too much. You can protect it through masks. It is suggested to use an activated carbon mask, the carbon content of which is more than 50%, which can effectively block toxic droplets and at the same time have a certain adsorption effect on volatile toxic gases.
