Monitoring air quality has become increasingly crucial in today’s world, as the impact of air pollution on human health and the environment has become more evident. Air pollution is a complex mixture of gaseous and particulate matter that can originate from various sources, including transportation, industrial processes, and natural phenomena like wildfires or volcanic eruptions.
The importance of air quality monitoring lies in its ability to detect and measure the levels of common air pollutants, such as particulate matter (PM), ground-level ozone (O3), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and volatile organic compounds (VOCs). These pollutants can have severe consequences for human health, including respiratory issues, cardiovascular diseases, and even premature death.
Furthermore, air pollution has a significant impact on the environment, contributing to climate change, acid rain, and the degradation of ecosystems. Monitoring air quality provides valuable data that can inform policymakers, industries, and individuals about the need for mitigation strategies and preventive measures to reduce emissions and protect public health and the environment.
