雾霾天气对心血管系统的影响以PM2.5最明显,PM即指大气中的固体或液体颗粒状物质。因为该颗粒可以直接通过气血屏障进入血液,停留在血管壁,引发血压波动,而对一些冠心病、高血压病等高危人群容易引发心脑血管意外。大雾里凝聚着大气中各种污染物质大雾里凝聚着大气中各种污染物质,如二氧化硫氧化硫、粉尘、病原微生物等,处在这样的环境中中,自身的抵抗力较弱人群,1至2天内可能就会引发上呼吸道感染、哮喘、湿疹、过敏等疾
The impact of haze on the cardiovascular system PM2.5 most obvious, PM refers to the atmosphere of solid or liquid particulate material. Because the particles can enter the blood directly through the blood-gas barrier, stay in the blood vessel wall, triggering blood pressure fluctuations, and for some coronary heart disease, hypertension and other high-risk groups easily lead to cardiovascular and cerebrovascular accidents. In the fog, there are various kinds of pollutants in the atmosphere, such as sulfur dioxide, sulfur dioxide, dust and pathogenic microorganisms, which condense all kinds of pollutants in the atmosphere, such as sulfur dioxide, sulfur dioxide, pathogenic microorganisms, etc. In this environment, 1 to 2 days may cause upper respiratory tract infection, asthma, eczema, allergies and other diseases
