Air Pollution can Kill 6.6 Million People a Year by 2050

In a study published in the journal Nature, scientists show that air pollution can kill about 3.3 million people a year in the world. Therefore, there are about 6.6 million people will die by 2050.

Scientists warned this on Wednesday, they said that air pollution was one of the main causes making people die prematurely. They also realized that the majority of those deaths are in Asia, because Asia is a area having large amount of energy emissions.

Jobs Lelieveld of Max Planck Institute of Chemistry in German said that in some countries, air pollution is actually a leading cause of death, it is also a major issue in many countries. The deaths from air pollution are most commonly chronic disease such as: heart disease, strokes and a lung disease, lung cancer…

Scientists also show that calculating the health and mortality effects of outdoor air pollution is not easy, partly because air quality is not monitored in every region and the toxicity of particles varies depending on their source.

In this study, Lelieveld’s team combined a global atmospheric chemistry model with population data and health statistics to estimate the relative contribution of different kinds of outdoor air pollution, mainly from so-called fine particulate matter, to premature deaths.

Their studies also show that emissions form heating and cooking have the largest death toll in China and India. While emissions from traffic and power generation are crucial in the United States.
