Ilmamääristä

Ilmamääristä, or air quality, refers to the condition of the air in a given area, typically measured in terms of its pollution levels and composition. Air quality is influenced by various factors, including natural sources such as volcanic activity and dust storms, as well as human activities like industrial emissions, vehicle exhaust, and agricultural practices. The primary pollutants of concern are particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and volatile organic compounds (VOCs).

Air quality is typically assessed using air quality indices (AQI), which provide a numerical value representing the overall pollution level and associated health risks. The World Health Organization (WHO) and national environmental agencies often establish guidelines for acceptable air quality levels, which may vary based on regional differences and health considerations.

Poor air quality can have significant health impacts, including respiratory and cardiovascular diseases, as well as exacerbating conditions such as asthma. It can also affect the environment, contributing to acid rain, smog, and the degradation of ecosystems. To mitigate these effects, governments and organizations implement various measures, such as emission standards, vehicle regulations, and public awareness campaigns.

Monitoring air quality is essential for public health and environmental protection. Continuous monitoring stations and satellite data provide real-time information on air quality levels, enabling timely interventions and policy adjustments. Public participation and community engagement are also crucial in promoting sustainable practices and reducing pollution sources.
