Pollution Sources

     The people all thought air pollution only have an influence on human's lungs, but the fact is that air pollution endangers the aspect of our health, which is quite widespread.

     When pollutants enter the lungs with breathing, the lungs are susceptible to inflam first. They may become systemic inflammation of the blood vessels and even the whole body when these inflammatory cells are transported around the body by the blood.

     These inflammation symptoms possibly cause the body to be sclerosis, like myocardial infarction, stroke, kidney failure and so on, even also irritate the autonomic nervous system, which causes Irregular Heartbeat! Therefore the air pollution which harms our body integrally shouldn't be ignored.
Additionally, air pollution was caused by second-hand smoke or vehicle exhaust which possibly increase the probability of infection. The gas emitted by smoking would increase the rate of oxidation in our body, cause inflammation, and then affect the concentration of hormones in our body. The increase in oxidative pressure in our body also reduces the function of cells of bone and then disrupts the balance of bone metabolism.

     As for the exhaust emitted by the car, which contains black carbon . When the black carbon is inhaled by us, it may affect parathyroid hormone and destroy the structure of bones of our body, which lead to decrease density of bone and increase risk of osteoporosis and fracture.

     Because PM2.5 is too tiny, even the bronchial cilia cannot be filtered, they eventually deposit on the bronchus, which lead to Bronchiectasis, fibrosis of lungs, vital capacity get low, and infect tuberculosis possibly.
