Air Pollution Crisis
Context
A recent study conducted by researchers from Singapore reveals alarming statistics regarding the health impacts of air pollution. The study using data for 40 years sheds light on the significant number of premature deaths worldwide attributed to man-made emissions and natural sources of pollution.
Key Findings:
- Between 1980 and 2020, approximately 135 million premature deaths globally were associated with exposure to particulate matter 2.5 (PM 2.5), tiny particles harmful to human health when inhaled.
- Diseases such as stroke, heart and lung disease, and cancer were responsible for premature deaths, highlighting the need for pollution mitigation strategies.
- Weather phenomena like El Nino and the Indian Ocean Dipole exacerbated the effects of pollution, leading to a 14% increase in premature deaths.
- Asia, particularly China and India, bore the highest burden of premature deaths attributable to PM 2.5 pollution, with over 98 million deaths recorded.
- Other countries such as Pakistan, Bangladesh, Indonesia, and Japan also experienced significant numbers of premature deaths ranging from 2 to 5 million people.
- Climate events like El Nino can elevate pollution levels, further contributing to premature deaths from PM 2.5 pollution.
- The World Health Organization highlights that ambient and household air pollution contribute to approximately 6.7 million premature deaths worldwide annually.
Major Air PollutantsThe major air pollutants include PM 10, PM 2.5, Nitrogen Dioxide, Ozone, Carbon, etc.
