Problem Statement 4j1g5b

Problem Statement. At present high levels of air pollution are recorded in many cities of different countries, in Venezuela although much air pollution is observed in comparison with other countries, this is a potential problem and growing every day, for many reasons, pollution atmospheric air or gases emitted by public transport is a big problem really hard to solve, but even when at home the vast majority of cars using gasoline, ie with internal combustion engines. Note that the engines that drive cars, trucks, buses and motorcycles, perform an incomplete combustion of fuel feeding and combustion waste is being thrown out through the exhaust system. Even if all the components of the car work perfectly; this will always generate pollutants elements. The situation worsens when well contaminants volumes corresponding to the normal operation are added flaws that increase the amount of gases and solid particles are thrown to the outside by vehicles. It is said that vehicles have a marked wear on engine parts or have not been properly toned, shed as much smoke from their exhausts and generate pollution hundreds of times higher than them is normal, since this Maturin view most built cars to public transport are in poor condition so it can be presumed that pollute to a greater degree than they should do. Likewise engines operating with diesel generating more pollutants than those using gasoline and these in turn are much more polluting. In many cases when examining the proportion of gases from cars, authorities are mainly concentrated on two types of pollutants: carbon monoxide and hydrocarbons. Carbon Monoxide (CO): Of the three major pollutants carbon monoxide is the most dangerous because you can not see or smell it. A concentration of 0.5% CO in the air can make an unconscious person and kill her within 10 to 15 minutes. Even a minor percentage concentration (0.04%) can cause headaches and threatening the life of a person after several hours of exposure. Hydrocarbons (HC): Hydrocarbon emissions are unburned gasoline and oil vapors. Although not directly harmful, they are major contributors to smog and ozone pollution. Hydrocarbons react in the atmosphere with the sun and break to form other chemicals that irritate the eyes, nose, throat and lungs. This problem is exacerbated by multiple factors each day, highlighting, among others: increased number of vehicles in good and in bad condition; the population growth and the emergence of new settlements in the different parishes, in some cases the result of invasions, which has sued the construction new urbanism, and to cover the shuttle has required adding more cars and / or new units to transport routes, generating more greenhouse gases every time. The effects of this pollution are felt in human health, mainly by the increase in respiratory conditions and the impact that causes the brain structures in the presence of carbon monoxide molecules displacing oxygen in the blood that irrigated.

Typical levels of pollution in the city cause headaches and nausea. When the intake of these gases by man occurs in confined areas the damage is fatal. In the environment the impact of stronger is the increase of greenhouse gases in the troposphere, with its consequent impact on global warming. Faced with this problem, researchers posed a series of questions to try to understand more precisely the study and save methodological guidance, and according to the results obtained for suitable and feasible solutions.
