Why settling velocities and aerodynamic diameters of PM are important characteristics to consider in determining engineering control strategies for various air pollutant particulates?
Settling velocities and aerodynamic diameters of PM are important characteristics to consider in determining engineering control strategies for various air pollutant particulate in order to have a variable to compare measurements against. This measurement helps determine the amount of air pollution being emitted into the atmosphere.

Is nitrogen dioxide considered an air pollutant?
Yes, nitrogen dioxide is considered an air pollutant.
What is notable pollutant?
A notable pollutant is particulate matter (PM), which consists of tiny solid or liquid particles suspended in the air. PM can originate from various sources, including vehicle emissions, industrial processes, and natural events like wildfires. It poses significant health risks, contributing to respiratory and cardiovascular diseases, and can also affect the environment by degrading air quality and harming ecosystems. Efforts to reduce PM emissions are crucial for public health and environmental protection.
