What are the top 3 sources of particulate matter in the atmosphere?

SOURCES OF PARTICULATE MATTER Figure 3.1 shows the major sources of primary emissions of PM2.5 in the United States. Major components of these particles include sulfate, nitrate, black carbon, organic carbon, and mineral dust; the latter two are themselves complex mixtures.

How do you collect particulate matter?

The most common instruments for measuring particulate matter measure either its concentration or size distribution. The most accurate measurements are obtained from instruments that use a gravimetric (weighing) method. Air is drawn through a preweighed filter, and particles collect in the filter.

Are plants better than air purifiers?

This study has been the basis for newer studies about indoor plants and their air cleaning abilities. While plants have less horse power than air purifiers, they’re more natural, cost effective, and therapeutic. Plants are also known to: increase mood and productivity.
