We often hear that new fog means smog in a certain city and the air quality index has dropped seriously. With the rapid development of the economic level, industrial pollution, automobile exhaust, etc. will seriously pollute the environment. So what are the hazards of environmental pollution to the human body? How should we protect the environment? Long-term air pollution and white garbage pollution are extremely harmful to the human body. Let us learn about the harm of environmental pollution to the human body. (1) Acute hazards: When the concentration of pollutants is very high in a short period of time, or when several pollutants enter the human body together, they may cause acute hazards to the human body. (2) Chronic hazards: Chronic hazards mainly refer to the harm caused by the continuous effects of small doses of pollutants on the human body. Such as the impact of air pollution on the incidence of chronic respiratory inflammation. (3) Long-term harm: The harm of environmental pollution to the human body usually manifests itself after a long latent period, such as the carcinogenic effect of environmental factors. The main carcinogenic factors in the environment are physical, chemical and biological factors. Physical factors, such as leukemia and lung cancer caused by external radiation or inhalation of radioactive substances; biological factors, such as tropical malignant lymphoma, have been proven to be caused by a virus transmitted by blood-sucking insects. Chemical factors: According to animal experiments, there are more than 1,100 carcinogenic chemicals. In addition, pollutants have a great impact on genetics. All living things have the characteristic of genetic variation. The harm of environmental pollution to human genetics is mainly manifested in mutagenic and teratogenic effects. Because people did not anticipate the negative impact of highly developed industry and failed to take precautions, three major global crises have occurred: resource shortages, environmental pollution, and ecological destruction. Humans continue to emit pollutants into the environment. However, due to the diffusion, dilution, oxidation-reduction, and biodegradation of the atmosphere, water, and soil, the concentration and toxicity of pollutants will naturally decrease. This phenomenon is called environmental self-purification. If the emitted substances exceed the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, and this is environmental pollution. The above is about the harm of environmental pollution to the human body. We should start protecting the environment from ourselves. We should learn to travel in an environmentally friendly way. We must do a good job in preventing environmental pollution at every step and insist on prevention first. The harm of the environment to the human body only manifests itself after a latent period, mainly causing mutations and teratogenesis, so we must always protect environmental hygiene and reduce pollution. I wish you good health. |
