Air Quality

Air Quality refers to the condition or cleanliness of the air in a specific environment, typically assessed by measuring the concentration of pollutants and harmful substances present in the atmosphere. It is an important indicator of environmental health, impacting both human health and ecological systems. Air quality can be affected by various factors, including industrial emissions, vehicle exhaust, natural occurrences like wildfires, and meteorological conditions. Common pollutants measured include particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and volatile organic compounds (VOCs). Air quality is often monitored through various indices, such as the Air Quality Index (AQI), which provides a standardized way to report and communicate the level of air pollution and its potential health effects. Good air quality supports healthier living conditions, while poor air quality can lead to respiratory problems, cardiovascular diseases, and other health issues, particularly in vulnerable populations. Efforts to improve air quality may involve regulatory measures, pollution control technologies, and initiatives aimed at reducing emissions from transportation and industry.
