Abstract

Statistical analysis for the emissions of some pollutants over Egypt during the period from 1850 to 2000 using the ACCMIP (Atmospheric Chemistry and Climate Model Intercomparison Project) history emission inventory dataset has been done. The seasonal and annual variations of the following compounds: Black Carbon (BC), Carbon monoxide (CO), Propane (C3H8), Formaldehyde (HCHO), Nitrogen Oxides (NOX), Toluene (C7H8), Ethylene (C2H4), Ammonia (NH3), Propene (C3H6), Sulfur Dioxide (SO2) and Organic Carbon (OC) have been examined. It is found that these pollutants are intense over Nile Delta and Greater Cairo (30.25º - 31.75º E and 29.25º - 31.25º N); it produces mainly from human activities. The annual analysis of these pollutants illustrates that four of them (C3H8, HCHO, SO2 and NOX) have the same behavior during the period of study, where an obvious increase appears from about 1930 to 2000.  Also, there are four pollutants (BC, C2H4, C3H6 and OC) that have the same behavior, where an evident increase appears from 1830 to 2000. The higher values of the coefficient of variation (COV) appears with the seasonal and annual time series of CH2O and C3H8 while the lower values of COV were found with the time series of C2H4 and C3H6. The trend analyses conclude that an obvious increase of all pollutants emissions except with NH3 where a negative trend appears with the seasonal and annual time series during the period from 1930 to 2000.
