... These estimates were made using unit loadings per urban land area. The annual loadings were calculated according to the coastal zones defined in this study, and the overall loadings for the United States and Canada were extrapolated to the world.

... The unit load per urban land area for coastal zone i, lad, was 12.22 g ~2 yr-i for coastal zone D, and 1.25 g nrC2 yr-i for all other coastal zones. The unit loads were set at higher values for Coastal Zone D because that is the coastal zone to which the Delaware River discharges.

... Calculations for the Coastal Basins of Mexico Because of a lack of data regarding urban land area for metropolitan areas in Mexico, the following method was used to calculate the land-based contributions of oil and grease to coastal zones H and I: 1. Oil and grease loading from Mexico was estimated using Equation I-4 with population and per capita motor vehicle data from World Resources Institute (1998)
From page 238...
... The final estimates of land-based contributions of oil and grease to the sea via all major inland river basins in the United States and Canada were then determined using the 1990s oil and grease data for the Delaware and Mississippi Rivers (Table I-8) with urban land area data from U.S.

To test the assumption that the measured oil and grease concentrations used for the current analysis were representative of ambient concentrations in North American rivers, average measured oil and grease concentrations for the 1990s STORET data on the Mississippi and Delaware rivers were compared with a database consisting of all of the 1990s oil and grease measurements gathered from STORET (145 data points)

While this concentration was greater than ambient river concentrations reported by other studies, it represents a conservative estimate of PAH concentrations in river water using the best available data. Furthermore, the calculated concentrations of PAH in the Mississippi River corresponded nicely with the range of total PAH measured by Michel (2001~.
