Today we review a meta-analysis of the links between high blood pressure and hypertension which lead to the number one cause of death in the world, cardiovascular disease, with air pollutants for both short and long term exposure. Results indicate short term exposure ot particulate matter (PM2.5 and PM10) and sulphur dioxide (associated with diesel vehicle emissions and coal burning) as well as long term exposure to nitrogen dioxide and PM10 (associated with vehicle emissions) are linked to a higher risk of hypertension. The mechanisms that lead to hypertension include inflammation and oxidative stress from exposure to air pollutants as well as imbalance of the nervous system from particulates.
