Source-This post on Air of the Anthropocene Initiative has been created based on the article “Global project ‘paints’ evidence of air pollution in India” published in “The Hindu” on 7 June 2024.
Why in News?
The “Air of the Anthropocene” project uses light painting to visualize air pollution in India, Ethiopia, and the UK. This emphasizes severe health risks and ignites global discussions on air quality.
About the ‘Air of the Anthropocene’ Initiative
1. The “Air of the Anthropocene” project is an international effort that combines art and science to show air pollution in a visual way using light painting.
2. Artists and researchers worked together to create photographic evidence of air pollution by using digital light painting techniques and low-cost air pollution sensors.
3. The “painting with light” team used low-cost air pollution sensors to measure PM mass concentrations. They used the sensors’ real-time data to control a moving LED array, which flashed more rapidly as PM concentrations increased.
About Particulate Matter
1. Particulate matter (PM) is a mixture of tiny solid particles and liquid droplets floating in the air. It includes things like dust, pollen, soot, smoke, and liquid drops.
PM10- inhalable particles, with diameters that are generally 10 micrometers and smaller; and.
PM2.5- fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.
2. These particles can be both organic (from living things) and inorganic (from non-living things) and come in various sizes and from different sources.
