Air Pollution – A Global Health Concern
- According to the annual (State of Global Air) SOGA 2020 report, In 2019, air pollution ranked fourth among all mortality risk factors globally surpassed only by the high blood pressure, tobacco use, and malnutrition accounting for nearly 6.67 million premature deaths.
- Ambient PM2.5 accounted for 4.14 million deaths, while indoor / household air pollution accounted for 2.31 million deaths.
- The global death rate attributable to air pollution exposure is 86 deaths per 100,000 people.
- In 2019, air pollution was the major reason for nearly 500,000 deaths among infants in their first month of life. Air pollution accounts for 20% of newborn deaths worldwide.
- In 2019, more than 90% of the world’s population experienced annual average PM2.5 concentrations that exceeded the WHO Air Quality Guideline of 10 μg/m3. The highest annual average exposures were seen in Asia (India), Africa, and the Middle East. The table below shows top 10 countries with the highest population- weighted annual average PM2.5 exposures in 2019
- The global average reductions in the percentage of populations exposed to indoor / household air pollution from 2010 to 2019 shows important variances between individual countries. The impact on the numbers of people affected is dominated by countries in South and East Asia, mostly in India and China, where there have been campaigns encouraging a switch to cleaner fuels. China reduced the percentage of its population exposed to household air pollution from 54% to 36%, while India reduced its percentage from 73% to 61% over the decade.
