The estimates are based on a refinement of a methodology developed by the Environmental Defense Fund in a 1988 study of Chesapeake Bay. The three-embayment study employed a spreadsheet methodology that produced estimates of nitrogen loadings from various nitrogen sources found in each of the study areas. Sensitivity analysis showed that atmospheric deposition has a significant effect on the nitrogen loadings delivered to the aquatic systems. More than 40% of the total nitrogen loads to the three systems resulted from nitrogen deposition68A Environmental Pollution & Control: Air Pollution & Control68D Environmental Pollution & Control: Water Pollution & Control99F Chemistry: Physical & Theoretical ChemistryAcid rainAquatic ecosystemsChesapeake BayData analysisData collectionDepositionEnvironmental impact assessmentsEnvironmental protectionEstimatesGalvestonGalveston bayLoadingMethodologyNitrogenSensitivity analysisSourcesTampa BayUnited StatesWater pollution sourcesWater qualityReport
