- Abstract
- Carbonaceous particulate matter (PM) has been studied for over a century and yet our knowledge is relatively limited, e.g., its physical and chemical properties, and the inception of nuclei formation. Carbonaceous PM is categorized as either a primary or secondary, where the difference is in the location of particle formation. Primary PM refers to particles that are formed at the source, i.e., within a flame, whereas secondary PM refers to particles formed in the atmosphere. Ambient aerosol particles can consist of both primary and secondary carbonaceous PM.The composition of carbonaceous PM has been traditionally divided into three fractions; elemental carbon (EC), organic carbon (OC) and carbonate carbon (CC).
