Every breath we take connects us with the environment, an invisible exchange that sustains life. The quality of the air we breathe has a major impact on our health and well-being and, with air pollution on the rise worldwide, is becoming a carrier of danger.
What does air pollution actually mean?
Air pollution is the release of pollutants into the air that are harmful to human health and the planet as a whole. The term relates to the indoor air quality (IAQ) or outdoor environment. Common sources of air pollution include industrial activities, the burning of fossil fuels, vehicular exhaust, dust, pollen, mold spores, volcanoes and wildfires. These kinds of events can have a significant impact on indoor quality. Find out more about how indoor air quality is linked to the quality of the ambient air. These Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide.
Data from the WHO (World Health Organization) shows that almost the entire world population (99%) breathes air that exceeds the limits set by the WHO and contains high concentrations of pollutants, with low- and middle-income countries being the most polluted.
Global air quality is closely linked to the climate and ecological balance of our planet. Common sources of air pollution, such as the burning of fossil fuels, also contribute to the emission of greenhouse gases. Consequently, initiatives to reduce air pollution serve a dual purpose: not only do they mitigate the incidence of diseases associated with poor air quality, but they also play a critical role in efforts to mitigate climate change, which is beneficial for both immediate and future environmental health.
What are the main impacts on human’s health?
The health effects of air pollution are profound and can affect almost every organ system in the body. Long-term exposure to air pollution can lead to chronic health conditions such as cardiovascular diseases, respiratory illnesses, and lung cancer, significantly reducing life expectancy. Epidemiological studies have demonstrated that prolonged exposure over years or lifetimes, predominantly leads to these diseases. Short-term exposure to elevated levels of air pollutants, even over hours or days, is not without consequence. It can lead to immediate health impacts like diminished lung function, aggravation of asthma symptoms, and an increase in respiratory and cardiovascular hospital admissions and mortality. This range of effects from short-term exposure highlights the acute risk that air pollution poses to public health.
The diversity of pollutants each contributes uniquely to health issues. For instance, fine particulate matter (known as PM2.5) is particularly harmful, penetrating deep into the lungs and even entering the bloodstream, causing inflammation and exacerbating health conditions like asthma and heart disease. Chronic exposure to these pollutants is linked to the development of diseases like chronic obstructive pulmonary disease (COPD) and aggravation of pre-existing heart conditions. These health effects of air pollution emphasize the urgent need for effective air quality management. Addressing air pollution not only improves individual health outcomes but also reduces the broader societal and economic burden of disease.
How to address air quality issues?
The correlation between air quality and public health demands sustained efforts from government, healthcare professionals, communities, but also by businesses to reduce exposure and mitigate these significant health risks. These can range from regulations limiting emissions from industrial plants and vehicles, promoting renewable energy sources, to individuals choosing public transport or reducing energy consumption at home.
To enable effective implementation of emission limits, continuous measurement of air pollutants is essential. TSI's air quality measurement solutions make this particularly easy. Designed for community watch groups, local EPA organizations, fugitive dust monitoring, government agencies, and municipalities, BlueSky™ Environmental Air Quality Monitors provide trusted results to support the needs of those looking to utilize low-cost gas sensing (CO, CO₂, NO₂, SO₂, O₃) capabilities, in addition to measuring particulate matter (PM) mass concentrations, temperature, relative humidity (RH), and barometric pressure (BP). Once your BlueSky monitors are set up and connected to a local Wi-Fi network, you can log into the new TSI Link™ Solutions, and see the air quality data from all your air quality sensors in real-time. The more monitors you have in your network, the more information you will have about air quality differences between locations. A network of multiple air quality sensors can show trends and hotspots, which can help you and your community make informed decisions.
