Air pollution in Georgia is linked to an average of 3,741 deaths per year
Air pollution is a pressing issue in Georgia, with far-reaching consequences for the health and well-being of its residents. According to the World Health Organization (WHO), Tbilisi, the capital city of Georgia, is one of the most polluted cities globally, with pollution levels 2.9 times higher than the norm. This pollution has a direct impact on the citizens of Georgia, with air pollution linked to an average of 3,741 deaths per year.
The main sources of air pollution in Tbilisi are vehicle emissions, a common issue in large cities with high populations. The older vehicles found in less developed countries are less efficient and contribute more to pollution. Additionally, emissions from industry and power stations burning fossil fuels also play a significant role. The lack of green spaces in Tbilisi further exacerbates the problem, as trees and other greenery can help absorb pollutants and improve air quality.
The effects of air pollution on human health are significant. Studies have shown a direct link between air pollution and adverse effects on a child's cognitive development, including neurological, psychological, and behavioural problems, as well as lower IQ and learning difficulties. Air pollution during pregnancy can also impact the mental development of the foetus and is associated with low birth weight in newborns. The infant brain is particularly sensitive to toxic substances in polluted air and can be damaged by very low doses of toxins.
The health impacts of air pollution extend beyond children and pregnant women. It is a significant contributor to mortality from various causes, including lung cancer, stroke, heart disease, and chronic lung diseases. In 2017, about one death for every thousand Georgians was attributed to air pollution, highlighting the urgency of addressing this issue.
However, there are ongoing efforts to improve air quality in Georgia. Environmental activists have been advocating for cleaner air, and data shows that overall air quality is improving. Emissions of key air pollutants have been declining since 1990, with significant reductions in carbon monoxide, nitrogen oxide, particulate matter, sulfur dioxide, and volatile organic compound levels. Additionally, policymakers are considering electrifying buildings, equipment, and transportation and transitioning to clean renewable energy sources. The bipartisan infrastructure bill and the Build Back Better Act are two pieces of legislation that could propel Georgia's cities towards a healthier and more sustainable future with reduced air pollution.

Augusta-Richmond County suffered 101 days of unsafe air quality in 2020
Georgia has been struggling with air pollution, which is a significant issue affecting climate change and ecosystems, and has a detrimental impact on human health and well-being. According to the World Health Organization (WHO), Tbilisi, Georgia's capital, is one of the most polluted cities globally, with pollution levels 2.9 times higher than the norm. The main sources of air pollution in Tbilisi are vehicle emissions, industrial emissions, and power stations burning fossil fuels.
In 2020, Augusta-Richmond County in Georgia suffered 101 days of unsafe air quality. Atmospheric scientist Michael Chang has been raising concerns about pollution in Georgia for three decades. Chang describes how a large air mass would settle over the state's metropolitan areas and remain there for extended periods. Augusta has been identified as the worst-affected city in Georgia, with the highest levels of pollution and ozone.
Particle pollution, which is prevalent in Augusta-Richmond County, poses a severe threat to public health. Research has linked both short-term spikes and long-term exposure to particle pollution with various adverse health effects, including respiratory and cardiovascular issues, decreased lung function, and heart attacks. The vulnerable groups most at risk of harm from air pollution include pregnant women, whose exposure has been associated with low birth weights, and children, whose cognitive development, neurological health, psychological well-being, memory, learning, and IQ can be negatively impacted.
While Georgia has made some progress in improving air quality, with emissions of key air pollutants declining since 1990, the state still faces significant challenges. Environmental activists have been advocating for further improvements, and federal programs such as the Clean Air Act and the electrification of cars have been implemented to address the issue. However, the health impacts of air pollution in Georgia remain a pressing concern, with the state ranking 47th in the "dirty city league" at the beginning of 2021.

Air pollution is caused by vehicle emissions, industry, and power stations
Georgia has been facing severe air pollution, which has been one of the country's biggest killers. According to data from the Institute for Health Metrics and Evaluation (IHME), in 2017, about one death for every thousand Georgians was attributable to air pollution. The World Health Organization (WHO) has also reported that polluted air is associated with 36% of lung cancer mortality, 34% of stroke mortality, 27% of heart disease mortality, and 35% of chronic lung disease mortality.
Air pollution in Georgia is caused by vehicle emissions, industry, and power stations. In Tbilisi, the capital of Georgia, the main cause of air pollution is vehicle emissions. The larger the city, the more vehicles are owned by its residents. Most of the vehicles in Tbilisi were manufactured before 1999 and are therefore not fitted with the latest filtration technology. As a result, the city's rush-hour roads are often clogged with old cars emitting dark-coloured fumes.
In addition to vehicle emissions, industrial emissions also contribute significantly to air pollution in Georgia. Cities with large industrial zones, such as Rustavi, experience high levels of air pollution from industrial activities. The construction sector is another major contributor to air pollution, with dirty construction projects releasing pollutants into the air.
Power stations fuelled by fossil fuels also play a role in air pollution in Georgia. In less developed countries, older vehicles and power plants tend to be less efficient than newer models, emitting higher levels of pollutants. Nitrogen dioxide, a harmful substance, is emitted primarily as a result of road transport emissions and power generation. However, since the World Health Organization declared a new pandemic, a decline in nitrogen dioxide concentration has been observed in Georgia.

Air pollution in Tbilisi is 2.9 times higher than the norm
Georgia has been facing air pollution problems for years. A 2016 study from the Technical University of Georgia found that the amount of green space per citizen in Tbilisi is just a fraction of European standards. The study also found a direct link between air pollution and a child's cognitive development, with several negative consequences for neurological, psychological and behavioural problems, memory, learning success, and verbal and nonverbal IQ. The report also suggests that air pollution during pregnancy is associated with low birth weight in newborns.
According to the World Health Organisation (WHO), Tbilisi is one of the most polluted cities in the world, with pollution levels 2.9 times higher than the norm. The main cause of air pollution in Tbilisi is vehicle emissions. As with most large cities with big populations, the majority of air pollution comes from vehicles. In addition, emissions from industry and power stations powered by fossil fuels contribute to the poor air quality in Tbilisi.
While air pollution is a significant issue in Georgia, there have been some improvements over time. Overall, air quality is improving in Georgia, with emissions of key air pollutants declining since 1990. For example, carbon monoxide levels have decreased by 69% since 1990, while nitrogen oxide levels are down by 60%. However, despite these improvements, air pollution remains a pressing issue in Georgia, with 7.6 million Georgians experiencing over 65 days of polluted air in 2020.
To address the problem of air pollution, Georgia is considering several legislative measures. Congress is reviewing the bipartisan infrastructure bill, which includes funding for cleaner transportation projects, such as electric vehicle charging stations. Additionally, the Build Back Better Act is being discussed, which could bring about even larger investments in environmental solutions to improve air quality.

Air pollution negatively impacts the mental development of foetuses
Georgia has been facing a significant air pollution problem, with Tbilisi, its capital, being one of the most polluted cities globally. The air quality index (AQI) in Georgia at the beginning of 2021 was "moderate," with a US AQI reading of 68, ranking the country 47th in the dirty city league. The main sources of air pollution in Georgia are vehicle emissions, industry, and power stations that rely on fossil fuels. The pollution levels in Tbilisi far exceed the norm, being 2.9 times higher, and the city has a shortage of green spaces. According to the World Health Organization (WHO), one out of every nine deaths worldwide is caused by polluted air, with Georgia's air pollution contributing to an average of 3,741 deaths annually.
Air pollution is a critical issue that negatively impacts both the environment and human health. It has been linked to climate change and the destruction of ecosystems, as well as various health issues. Research has shown that air pollution can have detrimental effects on foetal development, particularly on brain growth and cognition. Studies indicate that exposure to air pollution during pregnancy can result in adverse neurodevelopmental outcomes in children up to three years of age. The infant brain is highly sensitive to toxic substances, and even very low doses of toxins can cause damage.
Prenatal exposure to air pollution can lead to abnormal brain functions in foetuses and infants due to interactions between oxidative stress, ER stress, and neuroinflammation. Males are generally more susceptible than females to the adverse effects of in-utero air pollution exposure. Air pollution has also been associated with an increased risk of preterm labour, low birth weight, and pregnancy-related complications in the parent, such as preeclampsia and high blood pressure.
A study published by Imperial College London found a correlation between air pollution and low birth weight, with newborns weighing less than 2.5 kg. Additionally, a 2013 analysis of 14 population-level studies suggested a potential link between higher levels of certain pollutants, such as nitrogen dioxide, and an increased risk of low birth weight. Another study in Wuhan, China, examined the relationship between ambient air pollution and the risk of stillbirth.
While the mechanisms behind the negative effects of air pollution on neurodevelopment are not yet fully understood, it is known that PM2.5 and NO2, two major components of air pollution, contribute to elevated oxidative stress. This, in turn, leads to inflammatory responses, DNA damage, and disruptions in cellular signaling pathways. These factors can have long-lasting impacts on the developing foetus, potentially resulting in neurological dysfunction and adverse cognitive and psychomotor capabilities during childhood.
