"Painting with Light" Project on Air Pollution
Context
Researchers and artists teamed up for a project called "Painting with Light" to visualize air pollution in India and other countries. They used digital light painting and low-cost air pollution sensors to create striking images showing pollution levels.
Key Findings:
- In India, they found significant differences in air quality between urban Delhi and rural Palampur, with Palampur having much lower pollution levels.
- Similar variations were observed in Ethiopia and Wales, highlighting the impact of different environments on air quality.
- Particulate Matter (PM) pollution, particularly PM2.5, was the main focus due to its severe health impacts.
Why it matters?
- The team used low-cost sensors to measure PM concentrations in real-time. LED lights were controlled by these sensors to create visual representations of pollution levels.
- Long exposure photography captured these light patterns, with more dots indicating higher PM concentrations.
- The project makes invisible air pollution visible, sparking discussions and raising awareness about its health risks.
- It provides a simple way for people to understand and compare air pollution levels in different locations.
