Characterization of Benzene Samples Taken from Different Areas in Sudan Using Laser Induced Breakdown Spectroscopy (LIBS)

Abstract

Protecting the environment from all types of pollution is a key issue, especially air pollution in particular, because of that, the ecosystem as a whole is under threat. Sudan is one of the vast African countries, covering an area of about one million square miles, and suffering from air pollution. One of the causes of this pollution is the large number of cars and factories that use gasoline. Car exhausts and factory nozzles emit kinds of gases such as carbon monoxide, lead, sulfur and other gases that contribute to air pollution. Due to the large volume of use of gasoline in cars and factories, the low quality of purification and treatment leads to the production of gases that are extremely harmful to the environment. Therefore, it is necessary to examine and determine the components of benzene used in Sudan. The technique of Laser-Induced Breakdown Spectroscopy was used to characterize the benzene samples taken from different regions, and the results showed that they contain carbon and hydrogen that are the main component of benzene, in addition many elements harmful to the environment such as (Pb, Hg and Zn), which can cause cancer diseases, and can also cause great harms to animals, plants and soil.
