these motor vehicles run off of gasoline and diesel engines that particularly burn petroleum in order to release energy. The substance of petroleum contains hydrocarbons (huge particles made of hydrogen and carbon.) Ideally‚ thoroughly burning this chemical compound with an adequate amount of oxygen should result in forming nothing more than water and carbon dioxide. Unfortunately‚ fuels are not made of pure hydrocarbons and engines do not burn without producing harmful pollution. The effect of such

Environmental Chemistry It often matters how much given atoms combine‚ in what arrangement‚ with what others‚ what impulse they receive‚ and what impart. The same ones make up earth‚ sky‚ sea‚ and streams; the same as the sun‚ the animals‚ grains and trees‚ but mingling and moving in every different ways. - Lucretius (95-52 B.C.) in The Nature of Things I.

(Riser-Roberts‚ 1992). Problems associated with the cleanup of petroleum-contaminated sites have demonstrated that there is a need to develop remediation technologies that are feasible‚ quick‚ and deployable in a wide range of physical settings. Government‚ industry‚ and the public now recognize the potential dangers that complex chemical mixtures such as total petroleum hydrocarbons (TPH)‚ polychloro biphenyls (PCBs)‚ polycyclic aromatic hydrocarbons (PAHs)‚ heavy metals‚ and pesticides pose to human

Gasoline is obtained from petroleum in oil refineries‚ and used as fuel in combustion engines. It is made of over 250 types of hydrocarbons. Aromatic hydrocarbons like toluene and benzene are used to increase the octane rating of gasoline. Other additives are also added to improve engine performance and reduce the emission of harmful gasses formed as byproducts of the combustion process. Some hydrocarbons found in gasoline like benzene are carcinogenic. These hydrocarbons escape into the air around

Ø HOW IS COAL FORMED? Coal is a complex mixture of compounds of carbon‚ hydrogen‚ oxygen along with small amounts of nitrogen and sulphur compounds and some free carbon. Most of our coal was formed about 300 million years ago when much of the earth was covered by steamy swamps. Eventually bacterial and chemical action at high temperature and pressure inside the earth gradually changed the materials to coal. The slow chemical process of the conversion of wood into coal by a biochemical process

stratigraphic traps‚ and combination traps are responsible for the largest amounts of natural gas (Foote et al.‚ 1988). In a petroleum system like the Smackover Formation‚ it is important for traps to be present so that the hydrocarbons are unable to escape. However‚ Locklin‚ 1984‚ page 41‚ makes a clear argument why "apparent Upper Jurassic reservoir rocks have not trapped hydrocarbons more frequently." He reasons that potentially “large faults have caused breaking of mineralized seals and created excessive

It is the major fuel used on the planet‚ and is used in the production of many synthetic materials like plastics as well. Crude Oil can come in many different weights and colors‚ and can differ greatly in its composition. As little as half of the composition of heavy oils can be made up of hydrocarbons‚ while the lightest oils can be up to 97% hydrocarbons. There are four main hydrocarbons found in crude oil‚ in varying
