摘要
To the Editor:Air pollution can lead to respiratory and cardiovascular diseases(CVDs),and its impact on human health is very significant.Air particles less than 0.1µm can pass through the blood brain barrier,reach the brain,and enter the central nervous system,causing physiological and pathological changes.A study shows that long-term exposure to fine particulate matter(PM_(2.5))will increase the risk of CVDs among Chinese residents.^([1])Another study found that a short time exposure to low concentrations of air pollutants may also lead to the onset of acute coronary syndrome within one hour.^([2])A meta-analysis based on seven databases showed that environmental air pollution was positively correlated with elevated blood pressure and hypertension.^([3])Mounting evidence indicates that air pollution can cause cardiovascular and cerebrovascular diseases and affect human health furtherly.
