Health effect of air pollution on chronic diseases
With the development in cities and industries, scientists are worried about the impact of air pollution on human health. Air pollution is certainly one of the reasons that occurs pulmonary and cardiovascular diseases; but researchers in preventive healthcare work on learning about the relationship between chronic diseases and air pollution and have some scientific clues. One study was taking place in South Korea and the result shows that short- and mid-term exposure to air pollution quality with high level of particulate matter (both PM2.5 and PM10) and NO2(*1) is associated with changes in biological markers including fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) related to diabetes. Another study in the United States has some findings of a link of traffic pollution and an increased risk for changes in brain development relevant to neurodevelopmental disorders(*2). The other study which took 20 years in several countries in the European Union also has suggestive evidence about exposure to air pollution occurred by traffic including NO2 and SO2 may increase the risk of liver cancer(*4). With the mentioned studies, air pollution does have impact on human health, and higher risk of patients with chronic diseases. The public health experts have studied the data of confirmed and death cases and the coronavirus pandemic by area and find significant positive effects that poor air pollution does increase death of Covid-19(*3), specifically for elderly patients. A good management of chronic diseases for patients is very important, as well as living in a good air quality environment.
