What harm does environmental pollution do to the body?

The most direct impact of environmental pollution on humans is the decline in the quality of living environment and the impact on physical health. In today's life, our food, clothing, housing and transportation are all surrounded by chemicals. Although we all know the harm of environmental pollution, what effects does environmental pollution have on our bodies?

Environmental pollution has three main effects on human health:

(1) Acute harm: When the concentration of pollutants is very high in a short period of time, or when several pollutants enter the human body together, they can cause acute harm 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.
