Air quality monitoring

Definition

Air quality monitoring is the systematic measurement of air pollutants in the atmosphere to assess air quality and its effects on human health and the environment. This process involves the use of various instruments and techniques to collect data on pollutants such as particulate matter, nitrogen dioxide, sulfur dioxide, and ozone. Understanding air quality through monitoring helps to inform policy decisions, public health initiatives, and environmental regulations.
