Art and science come together in a unique collaboration to shed light on the invisible threat of air pollution. By using digital light painting and low-cost air pollution sensors, researchers and artists have managed to make the unseen visible. This innovative approach has allowed them to capture the levels of pollution in cities across Ethiopia, India, and the UK. The results have sparked important discussions within local communities and highlighted the potential health risks posed by air pollution.

The findings from the project “Air of the Anthropocene” revealed significant variations in air pollution levels between different locations. In Ethiopia, the team discovered that indoor air pollution in a kitchen using biomass stoves was up to 20 times greater than outdoor levels. Similarly, in India, there was a stark difference in PM2.5 concentrations between an urban area in Delhi and a rural playground in Palampur. The measurements in Delhi were at least 12.5 times higher than those in Palampur. In the UK, the researchers found large variations in air pollution around the Port Talbot steelworks, with PM2.5 concentrations exceeding the hourly average value.

The international team behind the project published their findings in Communications Earth & Environment, emphasizing the power of art in stimulating discussions around air pollution. Artist Robin Price and environmental scientist Professor Francis Pope spearheaded the initiative, aiming to make the invisible threat of air pollution more tangible. Through the creative use of light painting, they provided an accessible way for people to compare air pollution levels in different contexts.

By using low-cost air pollution sensors and a moving LED array to visualize PM concentrations, the team was able to create impactful images that resonated with a wide audience. Photographer Robin Price highlighted the significance of providing a visual understanding of air pollution, even for those without a scientific background. The approach of light painting not only raises awareness but also encourages individuals to take action in tackling air pollution and its detrimental effects on public health.

The “Air of the Anthropocene” project has been exhibited in various gallery shows and has been instrumental in raising awareness at an international level. Organizations such as the UN International Organization for Migration (IOM), the Foreign, Commonwealth, and Development Office (FCDO), and UN-Habitat have utilized the project to educate and engage communities on the pressing issue of air pollution. With air pollution being a leading environmental risk factor and a significant contributor to global mortality rates, initiatives like this play a crucial role in driving change and fostering dialogue around sustainable solutions.

The World Health Organization (WHO) estimates that a staggering 99% of the global population is exposed to polluted air, leading to approximately 7 million premature deaths annually. Particularly in Asia, countries like India and China continue to struggle with high levels of air pollution despite ongoing efforts to implement air quality policies. In Africa, there has been a concerning deterioration in air quality over the past few decades, with particulate matter (PM) emerging as a major driver of human morbidity and mortality. Heart disease, stroke, and various cancers are just some of the health impacts associated with exposure to PM.

The intersection of art and science offers a compelling platform for raising awareness about air pollution and its detrimental effects on human health and the environment. Through innovative approaches like light painting, collaborative initiatives can effectively communicate the urgency of addressing air pollution and inspire individuals to take concrete actions towards cleaner air and a healthier future.
