Monitoring The Gases Emitted from Electric Generators in Mosul City

   In the last period, the Iraqi environment witnessed many events and problems caused by the wars and the destruction of the infrastructure and research systems, including the electricity system, the spread of these generators caused major problems, especially in the environmental aspect, with regard to the issue of pollution. In this study, the city of Mosul was chosen for the purpose of measurement gas (H2S), gas (SO2) and gas (NO2) resulting from the exhaust of the generator, as (18) generators were selected in each side of the city with an average of (36) generators. The process of measuring the gases coming out of the generator exhausts was done with the height of the exhaust, and this method is the best way to measure the gases, but taking into account the different dimensions, which are (2, 5, and 8) meters. The research concluded that there are clear differences between the concentrations of gases from one generator to another, and the reason for this is due to the difference in the generating capacity of the generators in addition to the age of the generator, and the results of the study showed that most of the results for gases (sulfur dioxide, nitrogen dioxide and hydrogen sulfide) were higher than the permissible global and Iraqi limits for gaseous pollutants.
