Fine Particle Air Pollution Linked to 7% of Deaths in 10 Major Indian Cities
A study published Thursday estimates that air pollution from fine particles is responsible for approximately 7% of deaths in ten major Indian cities. Notably, mortality rates remain high even in relatively unpolluted metropolitan areas.
"Our findings, based on data from 2008 to 2019 in major Indian cities, indicate that around 7% of deaths are attributable to daily exposure to PM2.5 particles," generally known as fine particles, summarizes Jeroen de Bont, one of the study’s lead authors, in a press release. The study was published in The Lancet Planetary Health.
The researchers studied ten major Indian cities: Ahmedabad, Bangalore, Varanasi, Mumbai, Kolkata, Delhi, Hyderabad, Chennai, Pune, and Shimla. They analyzed the correlation between death rates and fine particle levels in each city, utilizing models capable of distinguishing between various air pollution sources, such as transportation and waste burning.
For their pollution threshold, the researchers adopted the World Health Organization (WHO) guideline, which stipulates that PM2.5 concentrations should not exceed 15 micrograms per cubic meter. Based on this threshold, they estimate that 7.2% of deaths, or approximately 33,000, over the studied period were linked to fine particle exposure.
This issue is particularly critical in India, one of the countries most vulnerable to pollution from these particles, which contribute to a range of pathologies, including strokes and lung cancer. Surprisingly, deaths from fine particle exposure are already elevated in the least polluted cities on the list, such as Mumbai and Kolkata.
While Indian authorities have set air quality improvement targets, they are using a threshold significantly higher than the WHO’s: 60 micrograms per cubic meter.
"By lowering these thresholds and enforcing them, we could potentially save tens of thousands of lives each year," asserts Joel Schwartz, another author of the study.
Air Pollution in India: Fine Particles Account for 7% of Deaths in Major Cities
Meta Description: A new study reveals that air pollution from fine particles is responsible for a staggering 7% of deaths in 10 major Indian cities, highlighting the urgent need for stricter air quality standards.
The Dire Toll of Fine Particle Pollution
Air pollution in India is a serious health concern, and a new study published in The Lancet Planetary Health has shed light on the devastating impact of fine particles on the country’s population. The study, conducted by researchers from the University of Washington and the Indian Institute of Technology Delhi, analyzed data from 2008 to 2019 in ten major Indian cities:
- Ahmedabad
- Bangalore
- Varanasi
- Mumbai
- Kolkata
- Delhi
- Hyderabad
- Madras
- Pune
- Shimla
The researchers found a strong correlation between daily exposure to PM2.5 (fine particles) and mortality rates in these cities. PM2.5 refers to particulate matter with a diameter of 2.5 micrometers or less, which are small enough to penetrate deep into the lungs and bloodstream.
The Shocking Findings: 7% of Deaths Attributable to Fine Particles
The study concluded that an estimated 7.2% of deaths (around 33,000) during the study period were directly linked to exposure to PM2.5. This translates to a staggering 7% of deaths being attributed to air pollution from fine particles across these major Indian cities.
The WHO Standard vs. India’s Threshold: A Critical Gap
The study used the World Health Organization (WHO) guideline for PM2.5 as a benchmark, which recommends a maximum concentration of 15 micrograms per cubic meter. However, India’s air quality standards allow for a much higher threshold of 60 micrograms per cubic meter. This significant disparity highlights the urgency of stricter air quality regulations in India.
The Impact of Fine Particle Pollution: A Growing Public Health Challenge
Fine particle pollution is known to cause a wide range of health issues, including:
- Respiratory problems: Asthma, bronchitis, and other lung diseases
- Cardiovascular disease: Heart attacks, stroke, and arrhythmias
- Cancer: Lung cancer and other cancers
- Neurological disorders: Dementia and Alzheimer’s disease
- Premature birth and low birth weight:
- Other health problems: Eye irritation, skin problems, and decreased lung function
The Need for Urgent Action: Saving Lives with Stronger Standards
The study’s findings underscore the urgent need for stricter air quality standards in India. "By lowering (these) thresholds and enforcing them, we could save tens of thousands of lives per year," says Joel Schwartz, co-author of the study.
Here are some key interventions that could drastically improve air quality and save lives:
- Enforce stricter air quality standards: Align with the WHO guidelines for PM2.5.
- Promote cleaner energy sources: Transition away from fossil fuels and invest in renewable energy like solar, wind, and hydropower.
- Improve public transportation: Encourage walking, cycling, and public transportation to reduce vehicle emissions.
- Control industrial emissions: Implement stricter regulations on industrial activities that contribute to air pollution.
- Reduce waste burning: Promote responsible waste management and discourage open burning of waste.
- Promote awareness and education: Educate the public about the dangers of air pollution and encourage them to take steps to protect their health.
Conclusion: Air Pollution is A Silent Killer
The study provides stark evidence of the devastating consequences of air pollution on public health in India. By taking decisive action to improve air quality and implement stricter regulations, India can protect its citizens from this silent killer and build a healthier future for all.
