Macedonia's Pollution: Understanding The Root Causes

Skopje, the capital of Macedonia, has been dubbed the most polluted city in Europe, with poor air quality causing the premature deaths of 1,300 people annually. The high levels of PM2.5 and PM10 particles, resulting from the burning of wood, rubbish, and dirty fuel, are the primary contributors to the city's pollution crisis. The unique geography of the city, nestled in a valley surrounded by hills and mountains, further exacerbates the problem by trapping toxic air. This has led to a political debate and demands for a health emergency declaration by Macedonia's green party.

Poor air quality in Skopje, the capital of Macedonia, is a major cause of concern

The high levels of PM2.5 and PM10 particles in the air are of significant concern. These tiny, breathable particles can damage lung tissue and are known to cause cancer and other diseases. The concentration of PM2.5 in Skopje is twice as high as in other European cities like Budapest or Bucharest, and the levels of PM10 have reached almost 14 times the highest acceptable standard set by European air quality standards. This has led to health warnings and calls for action from political parties and health authorities.

The pollution in Skopje is attributed to a combination of factors, including dirty fuel, inefficient stoves, and geographical challenges. Two-thirds of the city's residents burn wood, often using low-quality fuel or even rubbish due to a lack of access to cleaner alternatives. The city's location in a valley, surrounded by hills and mountains, further exacerbates the problem by trapping the pollutants and preventing their dispersion.

The impact of the poor air quality in Skopje is far-reaching. In addition to the health consequences, the pollution has affected the city's economy and the well-being of its residents. Many people choose to stay indoors or leave the city during periods of high pollution, impacting productivity and social life. The pollution has also deterred foreign workers and tourists, further straining the economy.

Addressing the air quality issues in Skopje is crucial, and some efforts have been made to mitigate the problem. However, experts and political parties argue that more urgent and comprehensive measures are needed, including improving access to cleaner fuels, implementing emissions standards, and creating no-vehicle zones. Finding effective solutions is essential to protect the health and well-being of Skopje's residents and to mitigate the economic and social impacts of air pollution.

PM 2.5 and PM10 particles, toxic specks that damage lung tissue, are present at high levels

PM 2.5 and PM10 particles are solid particles and liquid droplets that are so small they can be inhaled and cause serious health issues. PM10 particles are those with a diameter of 10 microns or less, and they can be inhaled into the lungs, potentially causing tissue damage and lung inflammation. PM2.5 particles are fine inhalable particles, with diameters of 2.5 micrometers or less, and they pose the greatest risk to health. These particles can travel into the deeper parts of the lung and deposit there, causing damage.

PM2.5 particles are often the result of emissions from the combustion of gasoline, oil, diesel fuel, or wood. They can also be formed from chemical reactions of gases in the atmosphere, such as sulfur dioxide and nitrogen oxides. PM10 particles are similarly formed, and they also include dust from construction, landfills, agriculture, wildfires, and industrial sources.

In Macedonia, the capital city of Skopje has been identified as having poor air quality, which has been linked to the premature deaths of 1,300 people annually. A study by the Finnish Meteorological Institute found high levels of PM2.5 particles in the city, which are believed to contribute to between 30 to 35 percent of deaths during the winter. Health officials have been warning about the deteriorating air quality in Skopje for years, highlighting the risks to the elderly and people with chronic illnesses.

The high levels of PM2.5 and PM10 particles in Macedonia, particularly in the capital city of Skopje, pose significant health risks to the population. These toxic specks can damage lung tissue and lead to a range of adverse health effects, including respiratory issues, heart problems, and even premature mortality. It is crucial for Macedonia to address this air pollution issue and improve the air quality for its citizens, especially those in vulnerable groups.

To combat this issue, Macedonia can implement a range of measures, such as reducing emissions from vehicles and industrial sources, regulating construction sites and agricultural practices, and promoting the use of cleaner energy sources. By taking proactive steps to reduce the presence of PM2.5 and PM10 particles in the air, Macedonia can improve the health and well-being of its citizens and create a more sustainable environment for future generations.

The pollution is caused by burning wood, rubbish, and low-quality fuel in inefficient stoves

In 2017, Skopje, the capital of Macedonia, was deemed Europe's most polluted city. Poor air quality was blamed for the premature deaths of 1,300 people annually. While there may be several factors contributing to Macedonia's pollution problem, one significant cause is the burning of wood, rubbish, and low-quality fuel in inefficient stoves.

Residential wood-burning is a common practice in Macedonia, especially during the winter months when heating is required. However, this practice can contribute significantly to air pollution, as smoke and pollutants from wood-burning stoves and fireplaces can affect both indoor and outdoor air quality. In addition to wood, the burning of rubbish and low-quality fuel can further exacerbate the pollution problem, as these materials often release even more harmful emissions when burned.

Wood-burning stoves and fireplaces can release various pollutants into the air, including particulate matter (PM 2.5), carbon monoxide (CO), and volatile organic compounds (VOCs). PM 2.5 refers to tiny particles smaller than 2.5 microns in size, which can lodge in the lungs and cause respiratory issues. Carbon monoxide, an odourless and colourless gas produced when wood is burned with insufficient oxygen, can reduce the blood's ability to supply oxygen to body tissues and increase stress on the heart.

Inefficient or older stoves can contribute even more to pollution levels. Chimneys and stoves that are not regularly cleaned and maintained can develop creosote buildup, which can fuel chimney fires. Additionally, factors such as improper burning techniques, burning wet wood, or using low-quality fuel can result in incomplete combustion, leading to increased smoke and pollutant emissions.

To mitigate the pollution caused by wood-burning, it is essential to use modern, efficient stoves that are EcoDesign-compliant. These stoves can reduce emissions by up to 66% compared to older models or open fires. Proper stove maintenance, including regular chimney cleaning and ensuring stoves are correctly operated, can also help reduce pollutant emissions. Additionally, individuals with respiratory or heart conditions should refrain from burning wood altogether and seek alternative heating methods.

The geography of Skopje, surrounded by hills and mountains, traps the pollution

Skopje, the capital of North Macedonia, is considered one of Europe's most polluted cities. The city's geography, encircled by hills and mountains, is a significant contributor to this issue. While the surrounding hills offer some protection to residents when smog levels are high, they also play a role in trapping toxic air pollutants, exacerbating the city's air quality problems.

Skopje's location in a valley, surrounded by higher elevations, creates a natural basin. This basin effect, coupled with the presence of hills and mountains, forms a lid that traps polluted air, particularly during the winter months. The warm air from the valley rises and collides with the cold, heavy mountain air above, creating a barrier that prevents the dispersion of pollutants. This phenomenon is a common issue in cities situated in similar geographical settings.

The topography of Skopje acts as a barrier to the natural dispersion of air pollutants, leading to their accumulation in the lower atmosphere. The city's elevation, ranging from 240 to 330 meters above sea level, contributes to this effect. The surrounding mountains, with peaks reaching over 1,000 meters, further confine the polluted air, preventing its escape and contributing to the city's poor air quality.

Compounding the problem is the city's industrial activity, with ageing factories operating in close proximity to residential areas. The emissions from these factories, combined with the burning of wood, coal, and rubbish for heating during winter, release harmful pollutants into the air. The geographical features of Skopje then act as a barrier, preventing the escape of these toxins and resulting in a toxic soup that residents are forced to breathe.

The impact of this trapped pollution on the health of Skopje's residents is significant. Studies have linked the city's poor air quality to premature deaths, with an estimated 1,300 lives lost each year due to air pollution. The pollution has also been associated with an increased risk of lung and heart diseases, cancer, and other respiratory issues. The social and economic costs are substantial, with the problem driving a brain drain, deterring foreign workers and tourists, and keeping residents indoors.

Political differences and a lack of government action have hindered progress

Skopje has consistently been identified as one of the most polluted cities in Europe, with air pollution levels reaching record highs during the winter months. The high concentration of PM2.5 and PM10 particles, which are toxic and can penetrate the lungs, has been a significant concern. Despite these alarming findings, there has been a perceived lack of sufficient action from the authorities to address the issue.

The Democratic Renewal of Macedonia (DOM), the country's green political force, has been vocal in criticizing the government's inadequate response. They have demanded that the government declare a state of emergency due to the health crisis caused by air pollution. While the authorities in Skopje implemented free bus transport to reduce car journeys, the DOM maintains that more drastic measures are necessary. They have proposed a no-vehicle zone in central Skopje, the temporary closure of construction sites, and the banning of vehicles that do not meet Euro 4 emissions standards.

The issue of air pollution in Macedonia has transcended political differences, with residents from various political backgrounds expressing their concerns. Some residents have taken it upon themselves to monitor air pollution levels and make informed decisions to protect their health, such as avoiding going outside on heavily polluted days. However, the lack of timely and transparent data provided by the authorities has been criticized, with a privately maintained website filling the information gap.

The social and economic costs of air pollution in Macedonia are significant. A study co-authored by Mihail Kocubovski from the country's institute of public health estimated the social cost of Skopje's air pollution to be between €0.5 billion and €1.5 billion. The pollution also impacts the economy by deterring foreign workers and tourists, contributing to the brain drain, and affecting the health and productivity of residents.

While there has been a slight decrease in PM2.5 pollution due to warmer winters, experts emphasize the need for more comprehensive efforts to transition to cleaner fuels. The lack of access to clean and efficient heating sources, particularly for lower-income households, remains a challenge. Without more decisive government action and political unity, progress in tackling Macedonia's pollution problem will continue to be hindered.
