Air travel exposes passengers to hidden pollution: Study
As the world becomes increasingly interconnected, air travel has become an essential mode of transportation for millions of people around the globe. However, a recent study has shed light on a lesser-known aspect of air travel: the high levels of pollution that passengers are exposed to during their journeys. The study, which measured pollution levels on 16 European flights, found that air travellers are exposed to unexpectedly high levels of ultrafine particles and black carbon, particularly during certain phases of flight.
The study’s findings are alarming, to say the least. According to the research, pollution levels spike during boarding, taxiing, and descent, with a significant decrease in pollution levels at cruising altitude. However, as the plane begins its descent and prepares to land, pollution levels rise again, exposing passengers to a second wave of pollutants. But the impact of air travel on pollution doesn’t stop there. The study also found that the particles and pollutants emitted by airplanes can spread kilometres beyond airports, affecting nearby neighbourhoods and communities.
The pollutants in question are ultrafine particles and black carbon, both of which are known to have negative impacts on human health. Ultrafine particles, which are smaller than 0.1 micrometres in diameter, can penetrate deep into the lungs and even enter the bloodstream, causing a range of health problems, including respiratory and cardiovascular disease. Black carbon, on the other hand, is a potent climate pollutant that is formed through the incomplete combustion of fossil fuels. It is known to contribute to climate change and has also been linked to a range of health problems, including cancer and respiratory disease.
The study’s findings are particularly concerning for people who live in close proximity to airports. Just like busy urban roads, airports are a source of significant pollution, with the particles and pollutants emitted by airplanes spreading far beyond the airport itself. This can have serious implications for the health and wellbeing of people living in nearby neighbourhoods, who may be exposed to high levels of pollution on a daily basis.
So, what can be done to reduce the impact of air travel on pollution? One potential solution is to improve the fuel efficiency of airplanes, which would reduce the amount of pollutants emitted during flight. Another solution is to implement stricter emissions standards for airplanes, which would help to minimize the impact of air travel on the environment. Additionally, airports and airlines could take steps to reduce pollution at airports, such as by using electric or hybrid vehicles for ground transportation and by implementing more efficient boarding and taxiing procedures.
For passengers, there are also steps that can be taken to minimize exposure to pollution during air travel. One simple step is to choose a seat as far away from the engines as possible, as pollution levels tend to be higher near the engines. Another step is to avoid travelling during peak hours, when pollution levels tend to be higher. Finally, passengers can take steps to reduce their overall exposure to pollution, such as by wearing a mask or using an air purifier.
In conclusion, the study’s findings are a wake-up call for the air travel industry and for passengers alike. While air travel is an essential mode of transportation, it is clear that it also has a significant impact on pollution. By taking steps to reduce pollution and minimize exposure, we can help to make air travel safer and more sustainable for everyone.
