“WHO estimates that around 7 million people die every year from exposure to fine particles in polluted air that penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases and respiratory infections, including pneumonia,” the report stated.

PM2.5 includes pollutants like sulfate, nitrate and black carbon, which pose the greatest risk to human health. Power plants, industry, agriculture, transport and inefficient use of energy by households are among the major causes of air pollution. Also read | What is PM 2.5?
