To the Editor:Air pollution can lead to respiratory and cardiovascular diseases(CVDs),and its impact on human health is very *** 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.
