Study reveals: Smoke from crop residue burning worsens air pollution in Indian cities
Identifying the main source of air pollution in Indian cities is crucial to reducing the many deaths caused by fine particulate matter (PM₂.₅) – deaths that during the harvest season can account for up to half of all air pollution-related fatalities. An international research team lead by the Paul Scherrer Institute (PSI), funded by the Swiss Agency for Development and Cooperation (SDC) has investigated in detail the sources of the organic components of fine particulate matter in the northern Indian cities of Delhi and Kanpur, located in the Indo-Gangetic Plain. Using novel high-resolution molecular measurement techniques and advanced data analysis, the researchers were able to precisely identify and quantify the sources of organic fine particulate matter.
