دراسة التلوث البيئي لتأثير المولدات الكهربائية على البيئة المحيطة (حالة الدراسة:المولدات المنزلية)

Abstract

Two aspects of environmental pollution have been dealt within the study which include air and noise pollution of electrical generators: In the air pollution, difference in contaminant concentrations between those caused by diesel and gasoline generator have been noticed when the contaminant concentrations(Soot, Pb, SO2, NO, CO) increasing from gasoline generators more than diesel generators and more than the proposed national specified in some cases. The diesel generators (10%) resulting of carbon monoxide from gasoline generators. Gasoline generators have more than the national specified (35 ppm) . The lead concentrations are lacking in diesel but the amount of lead increased to more than the proposed national specified (1.5μg/m3) in the case of the use of gasoline generator. The contaminant concentrations SO2 output of gasoline generators are very few compared with the contaminant concentrations SO2 output of diesel generators and higher than the national specified (0.1 ppm) in the case of diesel generators. The contaminant concentrations of NO from gasoline generator is slightly larger than the contaminant concentrations of NO output from diesel generators. The amount concentrations of particulate matter group generating by gasoline less than the diesel generating , the main problem of diesel engines are odor and smoke. Either noise pollution, the sound pressure level decreasing from (6-7 dBA) at doubling the distance between the source and the listener have been noticed , this means that the sound pressure level that is appropriate for Ugartmia and relatively less rate (6-7 dBA) at doubling the distance at the source approximately and compared with parameters WHO environmental noise (50-55 dBA) (period was 16 hours) and (EPA) (80 dBA) for Iraq residential areas, was developing the required distances.
