Researchers and artists collaborated to ‘paint with light,’ turning unseen air pollution becomes visible evidence. This innovative project attempts to highlight the health dangers that people who work and live in Ethiopia, India, and the United Kingdom encounter.

The team has created dramatic visual evidence of pollution levels in three countries’ capitals by integrating digital light painting with low-cost air pollution detectors. This approach has caused debate in local communities and revealed large variations in air pollution rates.

Apparent Air Pollution:

The project observed huge changes in air pollution throughout many locations:

Ethiopia: The researchers discovered that interior air pollution in a cooking area utilizing biomass burners for preparing food had PM2.5 concentrations that up to 20 times higher than surrounding outside values.

India: In two kids’ playgrounds, one in metropolitan Delhi and the other one within rural Palampur, PM2.5 levels were approximately 12.5 times fewer than in Delhi.

United Kingdom: During the summer, air quality evaluation and light painting at twilight near the Port Talbot steel industry in Wales revealed PM2.5 concentrations varying between 30-40 mg/m3, with an hourly average of 24 mg/m3.

A multinational team of academics and artists published their research in Nature Communications Earth & Environment, demonstrating how the photos from the ‘Air of the Anthropocene’ project sparked talks about the impact of air pollution.

Project Origins and Objectives:

Robin Price, an artist, and Professor Francis Pope, an environmental scientist at the University of Birmingham, launched the project. Professor Pope stated, “Air pollution is the major global environmental risk factor.” By painting with light to produce compelling visuals, we give individuals a straightforward way to compare air pollution in diverse contexts making what was previously unseen apparent.”


The team employed low-cost air pollution monitors to quantify particulate matter (PM) bulk concentrations. These sensors’ real-time data were utilized to control an oscillating LED array, which blazed faster as PM concentration grew.

Robin Price, the photographer, said: “By giving a graphical representation of air pollution that is available to people who don’t inevitably have scientific origins, the light painting technique may show that controlling air pollution levels may have an important effect on people’s regular lives.”

To create these photos, the artist took long-exposure photographs while moving the LED array directly in front of the camera. The flashes appeared as dots on the shot, and the number of spots indicated the PM concentration. Due to their movement, the artist was not visible in the photographs, but the brilliant LED flashes were.

Involving Organizations and igniting Dialogue:

Professor Pope noted the project’s greater significance: “Air of the Anthropocene provides spaces and places for debate about air pollution, utilizing art as a proxy to interact and create discussions about the problems linked to air pollution.”

According to co-author Carlo Luiu of the University of Birmingham, “Thanks to the influence of images, we can stir up people’s emotions fostering understanding and motivating people to share opinions and take action to combat air pollution.”

Worldwide Exhibitions and Awareness Campaigns:

The ‘Air of the Anthropocene’ initiative has been included in gallery shows in Los Angeles, Belfast, and Birmingham. Organizations such as the United Nations International Organization for Migration (IOM), the Foreign, Commonwealth, and Development Office (FCDO), and UN-Habitat have also used it to raise awareness about air pollution. Particularly, four pollution light images with associated narratives were commissioned for exhibition in Kampala, Uganda.

Air pollution is widely regarded as one of the foremost serious hazards to both the natural environment and human well-being, and it is a primary cause of death worldwide. The World Health Organization (WHO) believes that 99% of the world’s population breathes filthy air, which causes around 7 million early deaths each year.

Impact of Policy and Regulation:

Addressing air pollution necessitates strong rules and laws. Governments play an important role in establishing standards for air quality, monitoring levels of pollution, and enforcing restrictions. Stringent regulations have been developed in nations such as India and China to reduce emissions from industries, vehicles, and other pollutants. However, compliance remains a concern, requiring ongoing efforts to ensure compliance and manage growing pollution sources.

Advances in technology have transformed air quality monitoring. Low-cost sensors, like those employed in the ‘Air of the Anthropocene’ endeavor, provide real-time information on pollution levels, allowing for more accurate and localized monitoring. These advancements are critical to discovering pollution hotspots, evaluating the efficacy of mitigation techniques, and guiding public health actions. Furthermore, satellite-based sensor technology provides comprehensive information on air pollution over wide geographic areas, providing useful insights to policymakers.

Outreach and Education:

Improving public awareness regarding air pollution is critical to pushing change. Educational campaigns, community participation, and initiatives such as ‘Painting with Light’ are critical for alerting the public about the causes and health consequences of air pollution. These efforts, by making the undetectable visible, encourage people to take steps whether it’s pushing for better air policies, implementing sustainable habits, or making educated health decisions.

The partnership between scientists and artists in the ‘Painting with Light’ initiative demonstrates the value of innovative solutions to environmental challenges. Art has the unique capacity to communicate complicated scientific concepts in an understandable and emotionally resonant way. By transforming information into artwork, the initiative overcomes the gap between scientific study and popular perception, encouraging greater knowledge and engagement on the problem of air pollution.

Future Plans and Potential Impacts:

The ‘Painting with Light’ program serves as a paradigm for future projects that seek to address environmental issues through innovative and collaborative ways. Expanding the effort to incorporate more locations and environmental challenges could have a greater impact. Furthermore, incorporating these artistic techniques into educational programs and public health initiatives may broaden their reach and impact.


The ‘Painting with Light’ program exemplifies the remarkable connection between art and science. Visualizing the unseen not only informs the general public about the seriousness of air pollution but also encourages action to reduce its consequences. This unique project demonstrates how creative techniques can close the gap between complicated technical data and people’s awareness, raising interest and participation in addressing one of today’s most critical environmental concerns.
