15 February 2017 Current Affairs: According to a new study of global air pollution India’s rapidly worsening air pollution is now surpassing China’s as the deadliest in the world. The report was issued jointly by Health Effects Institute, a Boston research institute focused on the health effects of air pollution, and Institute of Health Metrics and Evaluation, Seattle based population health research centre.
The number of premature deaths in China caused by dangerous air particles PM2.5, has stabilised globally in recent years but has risen sharply in India. About 1.1 million people to die prematurely each year in India which has registered an alarming increase of nearly 50% in premature deaths from particulate matter between 1990 and 2015 period.
Global Scenario: The air pollution in recent times has worsened in parts of the world, including South Asia, but it improved in the United States and Europe.
US and Europe: Environmental regulations in US and actions taken by European Commission have led to substantial progress in reducing fine particulate matter (PM) pollution from industrialisation since 1990. US has experienced a reduction of about 27% in the average annual exposure to fine PM and there has been smaller declines in Europe. that reduced emissions from industrialisation
Particulate Matters are fine particles, less than fraction of the width of a human hair. These particles are released from vehicles, particularly those with diesel engines, industry, as well as from natural sources like dust.
They enter the bloodstream through the lungs, increasing the risk of stroke, heart failure and worsening cardiac disease, in addition also causing severe respiratory problems, like pneumonia and asthma.
