Polluted air enters the human body, which is mainly manifested in the harm of chemical substances, radioactive substances and biological substances to human health. It can lead to respiratory, cardiovascular and neurological diseases or other diseases.
(1) Burning coal and oil will release the most harmful chemicals into the atmosphere. The most common is total suspended particles, including dust, asbestos and metal dust. Harmful gases include sulfur dioxide, carbon oxides, ammonia oxides and hydrocarbons. There are also secondary air pollutants, photochemical oxidants and sulfuric acid fog. Harmful chemicals in the atmosphere directly stimulate the upper respiratory tract, causing bronchitis, emphysema and other diseases.
(2) Non-irritating harmful gases in the atmosphere, such as carbon monoxide, are more harmful because they cannot be detected by human senses. More than 30 kinds of harmful organic compounds, such as polycyclic aromatic hydrocarbons, can be detected in the atmosphere, among which benzo (a) pyrene is highly carcinogenic and contains potentially harmful chemicals, such as inorganic compounds such as cadmium, beryllium, antimony and lead, which are harmful to health and easy to form chronic poisoning. Some harmful chemicals can irritate eyes and skin.
(3) The atmosphere is polluted by radioactive substances, which often causes chronic diseases after human body irradiation.
(4) The floating dust in air pollution is very harmful to human respiratory tract.
(5) that influence of biological matt pollution on human health. Biological pollution is an air allergen, mainly produced by pollen, which can induce rhinitis, asthma and other diseases. Acid rain caused by air pollution has killed large areas of forests in Europe and destroyed the ecological environment all over the world.
