While consuming energy, human beings emit a lot of waste gas and smoke into the atmosphere, which seriously affects the quality of the atmospheric environment. The polluted air seriously affects people's health. Long-term effects of low-concentration air pollutants can cause diseases such as upper respiratory tract inflammation, chronic bronchitis and emphysema. It can also induce cardiovascular diseases such as coronary heart disease, arteriosclerosis and hypertension, and the frequent occurrence of lung cancer is also closely related to air pollution. In addition, air pollution will also reduce the immune function of the human body and make people's resistance to diseases decline, thus inducing or aggravating the occurrence of many diseases.
Air pollution is also very harmful to agriculture, forestry and animal husbandry. Generally, plants have weak resistance to sulfur dioxide, and a small amount of sulfur dioxide gas can affect the growth function of plants, causing defoliation or death.
