Abstract

A mathematical diffusion study was performed to determine the effect of ship stack gas emissions on ambient air quality. The Gaussian distribution equation, the Holland stack rise equation, the EPA Air Quality Display Model (modified), and input data from actual and theoretical conditions were used in the study. Isopleths were produced for particulate, carbon monoxide, sulfur dioxide (SO2), nitrogen oxides, and hydrocarbon emissions. Additional data are provided on the maximum groundlevel concentrations of each of these pollutants. A comparison of these data with federal ambient air quality standards notes that SO2 emissions from the use of 2.5% S in the fuel slightly exceed the secondary standard.
