Air pollution is a key risk factor for cardiovascular disease, and a major contributor to the global burden of disease. Long-term exposure to air pollution has also been linked to an increased risk of death from COVID-19. This dangerous triple threat of air pollution, COVID-19 and cardiovascular disease should be taken seriously, warn major health authorities.
Four leading cardiovascular organizations - the World Heart Federation (WHF), American College of Cardiology (ACC), American Heart Association (AHA) and European Society of Cardiology (ESC) - today released a joint statement urging the medical community and health authorities to mitigate the impact of air pollution on people s health.
Some are visible, such as dust, whereas others cannot be seen by the naked eye.
Materials such as metals, microplastics, soil and chemicals can be in particulate matter.
Particulate matter (or PM) is described in micrometres. The two main ones mentioned in reports and studies are PM10 (less than 10 micrometres) and PM2.5 (less than 2.5 micrometres).
Air pollution comes from burning fossil fuels, cars, cement making and agriculture
Scientists measure the rate of particulates in the air by cubic metre.
Particulate matter is sent into the air by a number of processes including burning fossil fuels, driving cars and steel making.
