Spain's Air Pollution: Strategies And Solutions

Air pollution is a pressing issue in Spain, with a report by Ecologistas en Acción revealing that around 30,000 people died in the country from air pollution in 2019. The report also highlights that 94% of the population was breathing polluted air, exceeding the recommended levels set by the World Health Organization. Spain's air quality issues are widespread, impacting approximately 44 million people and 88% of the country's territory. The main sources of pollution include road traffic, central heating systems, construction, and the use of fossil fuels for economic recovery. To address these concerns, Spain is facing the challenge of improving air quality while managing economic growth, with a particular focus on urban areas where the majority of the population resides.

A report by Ecologistas en Acción found that 97% of Spain's population is exposed to harmful levels of air pollution

A report by Ecologistas en Acción, a member of T&E, revealed that 97% of Spain's population is exposed to harmful levels of air pollution. The report, titled "Air Quality in Spain in 2017", analysed data from 800 official monitoring locations across the country. It concluded that approximately 45 million people were affected by contaminated air, with 88% of Spain's territory exposed to levels of pollution that pose a threat to human health.

The primary sources of pollution in urban areas, where most Spaniards live, are road traffic and industrial activities. The report also attributed the increase in pollution to the economic recovery, which has led to a rise in the use of diesel for cars, airplane jet fuel, and coal for electricity generation. In 2019, around 30,000 deaths in Spain were attributed to air pollution, according to a report by the conservation NGO Ecologistas en Acción. This report referenced the maximum contamination values recommended by the World Health Organization (WHO).

Among the various atmospheric pollutants, Ecologistas en Acción's report highlighted several as being particularly harmful to human health. These included suspended particles (PM10 and PM2.5), nitrogen dioxide (NO2), tropospheric ozone (O3), sulphur dioxide (SO2), and benzo(a)pyrene (BaP). Ozone, a prevalent pollutant during hot weather, can spread over long distances, affecting areas that might otherwise have cleaner air, such as Madrid's Sierra Norte.

Granada, despite having less traffic than Madrid or Barcelona, faces exacerbated pollution problems due to its topography and climate. The city is situated in a valley surrounded by mountains, which can trap polluted air during winter due to temperature inversions. Central heating systems and the burning of crop residue in the nearby agricultural region of La Vega further contribute to the issue. Weak winds in the region also fail to disperse the polluted air effectively.

To address these challenges, Spain has taken steps to improve air quality. For example, the country has implemented the Air Quality Index (AQI) to monitor and provide real-time data on air pollution levels. Additionally, there are ongoing efforts to reduce pollution from traffic and industrial sources, with a focus on urban areas where most of the population is affected.

Port areas in Spain suffer some of the worst air pollution

Maritime transport emissions contribute significantly to air pollution in Spanish port areas. With Spain's coastline on the Mediterranean Sea, the Atlantic Ocean, and the Bay of Biscay, the country has several busy ports, including those in Barcelona, Bilbao, and Valencia. The ships that dock at these ports release nitrogen oxides, sulphur oxides, and particulate matter into the air, which can have detrimental effects on human health and the environment.

Industrial activities in and around port areas also play a role in air pollution. Spain has a significant industrial sector, with activities such as manufacturing, refining, and chemical production. These industries can release various pollutants into the air, including volatile organic compounds, heavy metals, and hazardous air pollutants. The concentration of industrial facilities in port areas can lead to higher levels of air pollution for nearby communities.

Additionally, the burning of crop residues in agricultural regions near port areas contributes to air pollution. For example, in the agricultural region of La Vega, near the port city of Granada, the burning of crop residues releases smoke and particulate matter into the air. The topography and climate of Granada, situated in a valley surrounded by mountains, can trap polluted air during winter, exacerbating the air quality issues.

To address these issues, Spain has implemented several measures. Ecologists in Action, for instance, has developed a campaign with the slogan "Let's confine cars, let's recover our space," advocating for reduced traffic and improved air quality. There is also a focus on promoting energy saving, adopting better industrial techniques, closing coal-fired power plants, reducing aircraft usage, and declaring control areas for maritime transport emissions in the Mediterranean Sea. These efforts aim to improve air quality in port areas and across Spain, protecting the health and well-being of its citizens.

In 2019, around 30,000 people died in Spain from air pollution

Air pollution is a pressing issue in Spain, with far-reaching health, social, and economic impacts. In 2019, around 30,000 people died in Spain due to air pollution, according to a report by the conservation NGO Ecologistas en Acción. This figure underscores the urgency of addressing air quality issues in the country.

The report highlights that 94% of Spain's population, approximately 44 million people, were breathing polluted air with levels higher than the maximum contamination values recommended by the World Health Organization (WHO). This situation affected 88% of Spanish territory. The air pollutants identified as the most problematic for human health include suspended particles (PM10 and PM2.5), nitrogen dioxide (NO2), tropospheric ozone (O3), sulphur dioxide (SO2), and benzo(a)pyrene (BaP).

The impact of air pollution extends beyond the tragic loss of lives. It also contributes to an increase in medical costs and a decrease in productivity due to lost working days. Additionally, air pollution has been linked to various health issues, including respiratory diseases, lung cancer, premature births, low birth weight, alterations in cognitive development, and deficient lung function. The economic cost of pollution is substantial, with health impacts alone resulting in significant expenses.

To address this public health emergency, Spain has taken several measures. The Ministry of Health, Consumer Affairs, and Social Well-being is working on initiatives to mitigate the impact of air pollution on human health and reduce associated mortality and morbidity levels. The Air Plan and the Health and Environment Plan include coordinated efforts to protect the population's health and improve air quality.

Additionally, during the COVID-19 crisis, a drastic reduction in traffic resulted in unprecedented improvements in air quality in Spanish cities, dropping below legal limits and WHO recommendations. Ecologists en Acción proposed maintaining good practices, such as proximity shopping, voluntary teleworking, lower speed limits, and promoting active mobility to sustain these positive changes. While there has been a general reduction in nitrogen dioxide (NO2) levels, increases in suspended particles (PM10 and PM2.5) and sulphur dioxide (SO2) levels persist, along with stable tropospheric ozone pollution.

The main source of pollution in Spanish urban areas is road traffic

Air pollution is a pressing issue in Spain, with around 30,000 deaths attributed to it in 2019 alone. The country's air quality continues to fall short of EU standards, and it faces challenges in meeting the recommended maximum contamination values set by the World Health Organization (WHO).

Road traffic is a significant contributor to air pollution in Spanish urban areas. Motor vehicles emit various pollutants, including nitrogen dioxide (NO2), carbon monoxide, ultrafine particles, black carbon, polycyclic aromatic hydrocarbons, and metals. These emissions can have detrimental effects on the health of nearby residents, as evidenced by various studies. The Health Effects Institute identified an exposure zone of up to 300-500 meters from highways or major roads as the area most vulnerable to traffic emissions.

In Granada, a city with less dense traffic than Madrid or Barcelona, the topography and climate exacerbate the pollution problem. The city's location in a valley surrounded by mountains traps polluted air during winter due to temperature inversion. Weak winds in the region further contribute to the issue by failing to disperse the pollutants effectively.

Traffic emissions are not limited to exhaust fumes but also include non-combustion particles. These non-combustion emissions, such as trace metals and organics, originate from sources like tyre and brake wear and road dust. The abrasion of tyres on road surfaces and the wear and tear of brake shoes contribute to these non-combustion emissions, which can be just as harmful as traditional exhaust pollutants.

To address the issue of road traffic pollution, Spain has implemented measures to reduce noise pollution, which often coincides with air pollutant sources. These measures include introducing low-noise road surfaces, improving urban design to reduce traffic volumes, and restricting housing developments in high-noise areas. While these steps are positive, more comprehensive actions targeting specific air pollutants from road traffic may be necessary to significantly improve Spain's air quality and protect the health of its citizens.

The pollution problem in Granada is exacerbated by topography and climate

The unique climate of Granada, characterised by weak winds, also contributes to the city's pollution problem. These gentle breezes are insufficient to disperse the accumulated pollutants effectively. As a result, Granada's atmosphere becomes laden with harmful substances, including nitrogen dioxide (NO2), tropospheric ozone (O3), sulphur dioxide (SO2), and particulate matter (PM10 and PM2.5).

Particulate matter, specifically PM10, has become an increasingly prominent issue in Granada and its surroundings. This type of pollution consists of tiny particles such as dust, ash, and soot, with diameters between 2.5 and 10 microns. Unlike in larger cities, the problem is not primarily due to dense traffic but rather a combination of factors, including construction and demolition works, tyre abrasion on roads, and the wearing down of brake shoes.

The impact of topography and climate on Granada's air quality has been significant. The city's geographical setting, coupled with its unique weather patterns, has led to the entrapment and accumulation of pollutants. While human activities play a role, the natural environment significantly influences the dispersion of pollutants, underscoring the complex interplay between human practices and the Earth's systems.

To address this issue, Granada has established air quality monitoring stations that provide real-time data on various pollutants, including PM2.5, PM10, NO2, SO2, and O3. These stations help track the levels of these harmful substances and provide valuable information for implementing strategies to mitigate the pollution problem and improve the air quality for Granada's residents.
