A Critical Review on the Effect of Particulate Matter (PM) in Air on Public Health
According to the World Health Organization (WHO), particulate matter (PM) contamination causes around 800,000 premature deaths per year, ranking 13th in the world in terms of mortality. However, several findings revealed that the correlation is much stronger and more complicated than previously believed. PM is an element of emissions comprised of very small, acidic, organic compounds, metals, and particulate soil or dust particles or fluid droplets. The most consistent air quality component linked to human illness is PM, which is categorized by size. PM is likely to develop cardiovascular and cerebrovascular disorders due to the mechanisms of inflammation, overt and indirect coagulation activation, and direct translocation to the systemic circulation. The evidence on the cardiovascular system that shows a PM effect is strong. Coronary incidence and mortality rates in populations prone to long-term PM toxicity were significantly higher. Short-term acute emissions increase coronary incidence rates subtly within days of the pollution peak. While some evidence and associated mechanisms show a smaller outcome, the findings for PM’s cortical disease symptoms are not as promising. Respiratory infections are aggravated by exposure to PM. More analysis is needed to clarify the effects of structure, chemistry, and PM for vulnerable groups. The existing research indicates that PM toxicity causes a minor but significant increase in human morbidity and mortality. Air conditioners and particulate matter filters reduced internal heating, and cooking combustion and smoking cessation will reduce indoor PM exposure. These fundamental improvements can be beneficial to patients with acute and chronic cardiovascular and respiratory symptoms. This article provides an overview of the effects of atmospheric airborne suspended particulate matter on population morbidity and mortality. This critical review concludes with public health recommendations based on a summary of the published literature’s findings.
