Air Quality 2/7

p Gasoline : Composition , Effects and secondarys Gasoline is a product obtained from crude petroleum , and as such it is considered a fossil force out Crude oil undergoes a large-grained offset before it becomes blusteroline , and only approximately 0 .67 gallons of natural heavy weapon can be obtained from a gallon of oilGasoline is make up of hydro vitamin Cs , additives and blending agents Hydro nose candys atomic number 18 employ in the combustion process , while additives and blending agents argon used to better the effect of gasoline . Examples of those additives embarrass anti-knocking and anti-rust substancesGasoline rises include hydrocarbons , nitrogen oxide , carbon monoxide and carbon dioxide . Hydrocarbons contri only whene to lung damage and to ozone forming at ground level . north oxide is a cause of h ot rain . Carbon monoxide is a lethal gas and carbon dioxide contributes to global warmingSince gasoline emissions are harmful to the environment , a number of possible alternatives halt been suggested . One alternative is flavorless Natural Gas (CNG , a clear non-corrosive natural gas which can reduce ozone forming emissions by 80 . Fuel cells lag use hydrogen , which significantly reduce emissions and increase fuel economy . Liquefied crude oil Gas (LPG ) on the other hand comes from natural gas and crude oil and also reduces emissions . Electric vehicles (EV ) have been around from 1900s and use electricity as the source of power conflicting combustion engines it has perfectly no emissionsAll those mentioned above are practicable alternative to fuels . rough of them care fuel cells combined with a gasoline engine result in hybrid engines , thence less emission from the gasoline engine . Some like LPG fuel involves changes in the engine that would result in it beingn ess dependent on LPG instead of fuel .

Lastly , rough automobiles run on sources like electricity that does not come about any pollutants . All of these alternatives present different ways to barrier emissions , but the end goal is still the same , peg cumulation emissions so as to preserve the environment and ensure a clean futureReferencesAgency for Toxic Substances and Disease Registry .
