Quantification of hydrochloric acid and particulate deposition resulting from Space Shuttle launches at John F. Kennedy Space Center, Florida, U.S.A.

Results are presented from studies designed to identify deposition patterns and quantify the ecosystem loading rates of exhaust constituents (which are primarily Al2O3 and HCl) from the Space Shuttle solid rocket motors in the area of the Kennedy Space Center launch pad. Results of measurements indicate that, under certain meteorological conditions, as much as 7.1 x 10 exp 3 kg of particulates and 3.4 x 10 exp 3 kg HCL can be deposited to the near-field environment beyond the launch pad perimeter fence during one STS launch.
