Particulate Matter Sampling - Air quality index
A P T I 4 3 5 : A T M O S P H E R IC s a m p l i n g C O U R S E 4-1 Particulate Matter Sampling Introduction This chapter provides a definition for the subclasses of Particulate Matter (PM), addresses the rationale for size fractionation of particulates , and discusses Particulate Matter Sampling techniques in ambient air. PM is the generic term for a broad class of chemically, physically, and biologically diverse substances that exist as discrete particles (liquid droplets or solids) over a wide variation in the size of the particles. EPA typically characterizes the physical and chemical characteristics of PM through various pump-based and direct-reading continuous techniques. When suspended in air, PM is typically referred to as aerosol. Acute and chronic health effects have been positively associated with PM exposure. Because health effects and visibility are related to particle size, concentration, and chemical composition, EPA extensively characterizes PM.
