Relative Significance

As FSP is a fraction of RSP, they share similar emission sources and emission trends. Between 2001 and 2017, FSP emissions decreased by 59%.  Navigation, other combustion and non-combustion sectors were the top three sources of FSP emissions, accounting for 41%, 19% and 16% of total FSP emissions in 2017, respectively.

Similar to RSP, FSP levels measured at the EPD's general air quality monitoring stations did not follow closely with the FSP emission trend, indicating that the ambient FSP originates from both local and regional emission sources.
