What does the Influent consist of?

PM10: particulate matter, 10 microns (size) or smaller. SO2: sulfur dioxide. Pollutant concentrations: These are shown as hourly averages.

To reduce human health impacts, mining laws in some areas require buffer zones between surface mining operations and populated areas; thus, the effects of PM exposure may be lessened or infrequent ( Aneja et al., 2012 ). Particulate matter (PM), also known as aerosols, is a mix of fine dust and tiny liquid droplets suspended in the air. Even though much particulate matter is so small as to be invisible to the naked eye, it is possible to see others in high concentrations like smoke from a chimney, a candle, or cigarette. These particles are called PM10 (we say "P M ten", which stands for Particulate Matter up to 10 micrometers in size).
