What You'll Learn
Budapest's air pollution levels
Budapest, the ninth-largest city in Europe, has been described as having "alarming air pollution levels". In 2024, it ranked 242nd out of 372 European cities in terms of air pollution. This ranking is based on the concentration of PM2.5 particles in the air, which are considered the most dangerous among common pollutants. These particles can be as small as 2.5 microns in diameter and can penetrate deep into the lungs, even entering the bloodstream. This leads to serious health issues such as respiratory and cardiovascular diseases.
In Hungary, poor air quality is linked to around 10,000 premature deaths annually, as well as approximately one million cases of illness each year. Constant exposure to polluted air increases the risk of chronic diseases and early death. Other pollutants, such as black carbon and volatile organic compounds (VOCs), are also present in Budapest's air. These are produced by the incomplete combustion of fossil fuels, such as diesel and coal, and can have significant negative effects on both health and climate. Nitrogen dioxide, in particular, constantly breaches or exceeds safe levels.
Budapest's rapid economic development, population growth, and infrastructure expansion have likely contributed to its air pollution issues. The mass increase in buildings, industrial areas, factories, and daily human activity has resulted in higher emissions of atmospheric pollutants. The city's air quality is influenced by seasonal changes, with February having a higher PM2.5 reading of 20.7 μg/m³, while May and July have the lowest readings of 9 μg/m³ and 9.1 μg/m³, respectively.
To improve air quality, Budapest could implement environmental sustainability strategies. The establishment of more air quality monitoring stations would also provide a clearer picture of the city's pollution levels, helping residents, especially vulnerable groups like the elderly and young children, make informed decisions to protect their health.

The health impact of pollution
Budapest is the second fastest-developing economy in Europe, and as such, the city is experiencing a rapid growth in population and infrastructure. As a result, there are related pollution issues. The air quality in Budapest has been described as "harmful to human health", exceeding the maximum recommended limits of 10 μg/m3 set by the World Health Organization (WHO). The annual average concentration of PM2.5, or fine particulate matter, is 16 μg/m3. These fine particles can be as small as 0.001 microns in length and are a major component in the calculation of the overall air quality index (AQI). They pose a significant health risk to those who breathe them in, especially over long periods of time.
Nitrogen dioxide (NO2) is one of the most prominent pollutants in Budapest's atmosphere, constantly breaching or exceeding recommended safe levels. It is most prevalent in areas with high volumes of traffic and can cause damage to the lungs, triggering respiratory conditions such as emphysema and asthma. Other pollutants include sulfur dioxide (SO2), which is also present in the atmosphere, and ozone (O3), which is released into the atmosphere by industrial activities and motor vehicles. Budapest's PM2.5 readings tend to be at their highest during the winter months, with a noticeable decline in air quality around October. May and July are the cleanest months, with PM2.5 readings that fall within the WHO's target goal of less than 10 μg/m³.
Black carbon and volatile organic compounds (VOCs) are also present in Budapest's atmosphere. These are produced by the incomplete combustion of fossil fuels, such as diesel used in vehicles or coal in factories, and organic matter such as wood or charcoal used for traditional heating and cooking methods. Black carbon is a potent carcinogen and has negative effects on the climate. Examples of VOCs include benzene, xylene, and formaldehyde, all of which have significant effects on human health.
The high levels of pollution in Budapest have been linked to an average of 8000 annual deaths in Hungary, aggravated by the emission of gases from industrial activities and the burning of fossil fuels by motor vehicles. The city needs to establish urgent environmental sustainability strategies to improve air quality and mitigate the health impacts of pollution on its residents.

Nitrogen dioxide levels
Budapest, Hungary's financial heart, is the country's most populated city and the 9th largest in the European Union. As an economic hub, Budapest is the second fastest-developing economy in Europe. However, this rapid growth and boom in population and infrastructure have led to pollution issues.
Nitrogen dioxide (NO2) is a significant contributor to Budapest's air pollution. NO2 is produced by the combustion of fossil fuels, particularly in motor vehicles, and the burning of biomass and the use of chemical fertilizers in agriculture. According to one source, out of all the pollutants in the air in Budapest, nitrogen dioxide may have the most significant effect on pollution levels, constantly breaching or exceeding safe levels.
Kovács et al. (2021) studied atmospheric pollution in Budapest and found high levels of atmospheric pollutant dispersion, with average values of NOx emissions of 9.3 t/day. This is concerning as NOx, or nitrogen oxides, can form ground-level ozone (O3) when reacting with volatile organic compounds (VOCs) in the presence of sunlight. Ground-level ozone is a harmful pollutant and a major component of smog, which can have detrimental effects on human health and the environment.
Budapest's air quality has shown some improvement in recent years, particularly during the COVID-19 epidemic, when there was a significant reduction in pollution levels. The cleanest months tend to be from March to September, with May and July usually having the lowest pollution levels. However, during the colder months, pollution levels tend to increase, with February having a PM2.5 reading of 20.7 μg/m³ in 2019, which is above the World Health Organization's recommended target of less than 10 μg/m³.
Overall, while Budapest's air quality is not among the worst globally, there is a need for further improvement to reduce the health risks associated with air pollution and to mitigate climate change.
