An explosion occurred near a hotel in Zhujiang. Is the air after the explosion harmful to the human body?

There must be a fire. After the explosion, a fire will definitely occur. After the explosion, many harmful substances to the human body will be produced, such as the carbon dioxide we usually exhale. In addition, the air will also be mixed with various substances. What other harmful substances are there, such as dust pollution, as well as sulfur dioxide, nitric oxide, metal pollution and many other harmful substances? First of all, the most harmful thing to the human body is dust pollution, because the diameter of dust is very small, between 0.5-5 microns. and the dust will float in the air. Once the dust is inhaled into the body, the dust will quickly enter the lungs, where it will be sent to the whole body along with the blood circulation. The dust itself does not contain many toxic substances. , when it is sent to the whole body, it will continue to circulate with the blood of the whole body, and soon it will be expelled from the body, which will directly cause great harm to the heart, lungs and respiratory tract, especially the respiratory tract. Nowadays, dust pollution is basically listed as a hazard in all parts of the world. It is one of the most harmful substances to the human body, and there will be a large number of dust particles floating in the explosion area, making it difficult to guard against. If you want to enter this area, you must wear a qualified mask. If possible, you should stay away from the area appropriately and then Sulfur dioxide, everyone knows about acid rain. In some areas of my country where heavy industry is developed, acid rain occurs because the gases emitted by heavy industry contain sulfur dioxide. Acid rain will have a great impact on crops, our buildings, and our travel. Especially crops will suffer a fatal blow, and the main component of acid rain is sulfur dioxide. After the explosion, a large amount of sulfur dioxide will be produced. When sulfur dioxide combines with water in the air, it will become our acid rain. Sulfur dioxide will cause many harm to the human body. Major hazards, for example, will directly increase the prevalence of respiratory diseases, and will rapidly worsen the condition of patients who already suffer from respiratory diseases. At the same time, it will also increase the risk of heart disease. People in this area will You will feel obvious discomfort. Secondly, the explosion will produce many kinds of metal pollution, such as lead, zinc, mercury and many other harmful metal substances. Once these metal substances are inhaled into the body, they will cause cardiovascular, central nervous system, and respiratory tract etc. A variety of chronic diseases, even cancer, and the most serious thing is that the harmful metal substances produced by the explosion will always float in the air and even combine with water, which will cause great harm to newborns in the area. Usually The performance is that newborns in the area will develop slowly and have low intelligence, which is very different from ordinary children of the same age. Moreover, the sickness rate of newborns will be much higher than in ordinary areas. After the explosion, there will be many other things floating in the air. Hazardous substances, including chemical and biological harmful substances, stench is one of them. The stench is like the smell emitted by broken eggs at home, or the smell in the smelly ditch. We call it stench, and stench brings people The most direct impact is that there will be vomiting symptoms, followed by a series of symptoms such as anorexia and nervous sensitivity.

So if you are in this area, you should not open the windows at ordinary times. It is recommended to go out. Wear a mask and try not to go out. You can eat more pears and black fungus, which are good for the lungs.
