associated recovery and cleanup operations led to emissions of
pollutants to the atmosphere. HCs evaporating from the oil slick
were the largest source of primary air emissions. Once in the air,
these HCs produced SOA and gaseous pollutants such as ozone
and PAN. Large concentrations of PAHs were not found in the
SOA. Significant ozone production was confined to the area
downwind of both evaporating HCs from the spill and NOx emissions
from the cleanup and recovery operations. The emission
factors for NOx, CO, and soot or black carbon from in situ burning
of surface oil, flaring, and ship emissions were similar to those
previously reported.
