'Greatest threat': Over 50 crore Indians to lose 7.6 years of life if current pollution levels persist, claims study
The Energy Policy Institute at the University of Chicago (EPIC)'s Air Quality Life Index found that pollution is shortening lives by almost 10 years in Delhi-NCR.
India is world's second most polluted country
As per the study, India is the world's second most polluted country after Bangladesh.
Pollution shortening lives by almost 10 years in Delhi-NCR
While some areas of the country are much worse than average, the air pollution is shortening lives by almost 10 years in the National Capital Territory of Delhi, the most polluted city in the world, the study claimed.
The analysis said Delhi stands to gain life expectancy by 10 years on average if annual average pollution levels do not exceed five micrograms per cubic metres.
Pollution is greatest threat to human health in India
The study said that all of India's 1.3 billion people live in areas where the annual average particulate pollution level exceeds the WHO guideline.
"More than 63 percent of the population live in areas that exceed the country's own national air quality standard of 40 g/m3. Measured in terms of life expectancy, particulate pollution is the greatest threat to human health in India, reducing life expectancy by 5 years," the study stated.
Smoking reduces average life expectancy by 1.5 years
In contrast, child and maternal malnutrition reduce average life expectancy by about 1.8 years, while smoking reduces the average life expectancy by 1.5 years, the study found.
Pollution takes 2.2 years off global average life expectancy
Globally, the report found that particulate air pollution takes 2.2 years off global average life expectancy, or a combined 17 billion life years, relative to a world that met the WHO guideline (5 g/m3).
Pollution has a huge impact on life expectancy
This impact on life expectancy is comparable to that of smoking, more than three times that of alcohol use and unsafe water, six times that of HIV/AIDS, and 89 times that of conflict and terrorism, as per the analysis.
South Asia worst hit due to pollution
The study highlighted that in no region of the world is the deadly impact of pollution more visible than in South Asia, where over half of the life burden of pollution occurs.
Residents there are expected to lose about five years of their lives on average if the current high levels of pollution persist, and more in the most polluted regions.
