Sulfur dioxide concentration measurement

Sulfur dioxide (SO2) concentration measurement involves determining the amount of this gas in the air, which can come from sources like industrial processes and vehicle emissions. Various methods can be used, such as using sensors or collecting air samples for laboratory analysis. The results are often expressed in parts per million (ppm) or micrograms per cubic meter (µg/m³). Monitoring SO2 levels is important because high concentrations can harm health and the environment, leading to respiratory problems and acid rain. Regular measurements help ensure air quality standards are met and public health is protected.
