Air Pollution: Health Hazards And Conditions

Air pollution is the presence of contaminants in the atmosphere, such as dust, fumes, gas, mist, smoke or vapour, in quantities that can be harmful to human health. Both short-term and long-term exposure to air pollution can lead to a wide range of diseases, including stroke, chronic obstructive pulmonary disease, trachea, bronchus and lung cancers, aggravated asthma and lower respiratory infections. It can also cause coughing, itchy eyes and worsen many breathing and lung diseases.

Asthma attacks

Air pollution can cause a wide range of health problems, including asthma attacks. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases.

For people with asthma, air pollution can make it harder to breathe, trigger asthma attacks, or cause wheezing and coughing. Air pollution can also increase the risk of respiratory infections, heart disease, stroke, and lung cancer, and more severely affects people who are already ill. People’s health risks from air pollution vary widely depending on age, location, underlying health, and other factors. Many studies show that low-income communities and minority populations are disproportionately exposed to air pollution and are more vulnerable to adverse health impacts.

Data from the Minnesota Department of Health shows disparities in heart and lung disease by age, race/ethnicity, income level, and geography. Minnesota also has significant disparities in asthma prevalence by race/ethnicity. The asthma hospitalization rate among Twin Cities children is more than 50% higher than among children living in Greater Minnesota.

The World Health Organization (WHO) provides evidence of links between exposure to air pollution and type 2 diabetes, obesity, systemic inflammation, Alzheimer’s disease and dementia. The International Agency for Research on Cancer has classified air pollution, in particular PM2.5, as a leading cause of cancer. A recent global review found that chronic exposure can affect every organ in the body, complicating and exacerbating existing health conditions.

Lung cancer

Air pollution can cause a variety of health conditions, including lung cancer. Lung cancer is caused by breathing in air pollutants, which can enter the bloodstream and circulate throughout the body. These pollutants include dust, fumes, gas, mist, odour, smoke and vapour.

The impact of air pollution on lung cancer risk varies depending on age, location, underlying health, and other factors. Studies have shown that low-income communities and minority populations are disproportionately exposed to air pollution and are more vulnerable to adverse health impacts, including lung cancer.

To reduce the risk of lung cancer, it is important to limit exposure to air pollution. This can be done by reducing the use of vehicles, avoiding smoke and industrial emissions, and minimising the use of chemicals in the home.

Heart disease

Air pollution can cause a wide range of health issues, including heart disease. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases.

Air pollution can cause or worsen heart disease. The small size of some air pollutants means they can penetrate into the bloodstream via the lungs and circulate throughout the entire body. This can lead to systemic inflammation and impact the heart. Air pollution can also cause oxidative stress, immunosuppression, and mutagenicity in cells throughout the body, impacting the heart.

People with existing heart disease may be more vulnerable to the adverse health impacts of air pollution. Studies show that low-income communities and minority populations are disproportionately exposed to air pollution and are more vulnerable to its health impacts. Data from the Minnesota Department of Health shows disparities in heart disease by age, race/ethnicity, income level, and geography.

Air pollution can also increase the risk of other health issues that may impact the heart, such as respiratory infections, stroke, and lung cancer. It can also worsen existing breathing and lung diseases, leading to hospitalizations.

Stroke

Air pollution can cause a wide range of health issues, including stroke. Both short-term and long-term exposure to air pollution can lead to a stroke. A stroke is a serious life-threatening medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and can cause permanent brain damage and even death.

Air pollution can increase the risk of stroke by contributing to the formation of blood clots, which can then travel to the brain and block blood flow. Additionally, air pollution can cause inflammation and damage to the blood vessels, making them more susceptible to clotting and narrowing, which can also lead to a stroke.

The impact of air pollution on stroke risk is particularly significant for people who are already at a higher risk for stroke, such as those with high blood pressure, diabetes, or a history of heart disease. Air pollution can worsen these underlying conditions and increase the likelihood of a stroke occurring.

Additionally, air pollution can also affect the brain directly. Fine particulate matter and toxic pollutants can enter the bloodstream and travel to the brain, causing inflammation and damage to brain cells. This can increase the risk of stroke and other neurological conditions, such as dementia and Alzheimer's disease.

It is important to note that the effects of air pollution on stroke risk are not limited to outdoor air pollution. Indoor air pollution, such as from cooking fumes, secondhand smoke, and mould, can also contribute to stroke risk. Therefore, it is crucial to take steps to reduce exposure to air pollution, both indoors and outdoors, to help lower the risk of stroke and improve overall health.

Lung tissue swelling and irritation

Air pollution can cause a variety of health problems, including lung tissue swelling and irritation. When we breathe in air pollutants, they can enter our bloodstream and contribute to coughing or itchy eyes and cause or worsen many breathing and lung diseases. The main pathway of exposure from air pollution is through the respiratory tract.

Breathing in these pollutants leads to inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout our body, impacting the lungs, heart, and brain, among other organs. Almost every organ in the body can be impacted by air pollution. Due to their small size, some air pollutants are able to penetrate into the bloodstream via the lungs and circulate throughout the entire body, leading to systemic inflammation and carcinogenicity.

People with asthma or chronic obstructive pulmonary disease (COPD/emphysema or chronic bronchitis) are particularly vulnerable to the effects of air pollution, which can make it harder to breathe, trigger asthma attacks, or cause wheezing and coughing. Air pollution has also been linked to an increased risk of respiratory infections, heart disease, stroke, and lung cancer, and more severely affects people who are already ill.

The health risks from air pollution vary widely depending on age, location, underlying health, and other factors. Many studies show that low-income communities and minority populations are disproportionately exposed to air pollution and are more vulnerable to adverse health impacts. Data from the Minnesota Department of Health, for example, show disparities in heart and lung disease by age, race/ethnicity, income level, and geography.
