which country in the world has the most air pollution?
india
air pollution occurs when harmful or excessive quantities of substances including gases, particles, and biological molecules are introduced into the earth's atmosphere. air pollution in india is a serious issue, ranking higher than smoking, high blood pressure, child and maternal malnutrition, and risk factors for diabetes. at least 140 million people breathe air 10 times or more over the who safe limit and 13 of the world's 20 cities with the highest annual levels of air pollution are in india. air pollution contributes to the premature deaths of 2 million indians every year. in urban areas, most emissions come from vehicles and industry, whereas in rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. in autumn and winter months, large scale crop residue burning in agriculture fields – a low cost alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution. india has a low per capita emissions of greenhouse gases but the country as a whole is the third largest after china and the united states. a 2013 study on non-smokers has found that indians have 30% lower lung function compared to europeans.

people who live in areas where particulate matter (pm) air pollution is higher tend to have more health problems across the board. short-term and long-term effects of ambient air pollution are associated with an increased mortality rate, including infant mortality. air pollution is consistently associated with post neonatal mortality due to respiratory effects and sudden infant death syndrome. specifically, air pollution is highly associated with sids in the united states during the post-neonatal stage. high infant mortality is exacerbated because newborns are a vulnerable subgroup that is affected by air pollution. newborns who were born into these environments are no exception. women who are exposed to greater air pollution on a daily basis who are pregnant should be closely watched by their doctors, as well as after the baby is born. babies who live in areas with less air pollution have a greater chance of living until their first birthday. as expected, babies who live in environments with more air pollution are at greater risk for infant mortality. areas that have higher air pollution also have a greater chance of having a higher population density, higher crime rates and lower income levels, all of which can lead to higher infant mortality rates.
