“…At present, hundreds of atmospheric pollutants have caused harm to human health, production, and life, which can be summarized as granular pollutants (such as dust, coal dust, smoke, and metal particles) and gaseous pollutants (such as SO 2 , NOx, CO, CH 4 , ammonia compounds, and halogen compounds) according to their existence. The results of epidemiological studies show that AP not only causes severe respiratory and cardiovascular diseases [55,56] but can also affect the nervous system (related to cognitive ability), cause long-term harm to academic and employment performance, and seriously threaten human health and safety [57,58]. Among all kinds of AP, particulate matter with an aerodynamic diameter of less than 2.5 µm (PM 2.5 ) is continuously deposited into the blood circulation system in the alveoli, which can cause diseases related to cardiopulmonary dysfunction, and asthma, cough, dyspnea, cardiovascular diseases, and other diseases may occur; PM 2.5 can even cause liver failure.…”
