first time the composition of air pollution in Bogotá and its principal components. These were identified to be the following: Sulfur Dioxide (SO2)‚ Nitrogen Oxides (NOx)‚ Total Suspended Particles (TSP)‚ Carbon Monoxide (CO)‚ Hydrocarbons (HC)‚ and Ozone (O3). It was estimated that 75% of the pollutants’ annual emissions correspond to Particulate Matter. The study determined that the levels of CO‚ HC‚ SO2 and Particulate Matter were not above the limits defined as safe by the WHO. This led to JICA

The Birth of EPA The EPA is an organization whose purpose is to preserve and protect the environment that we live in. EPA stands for Environmental Protection Agency and it is one of the main reasons that our planet has survived thus far. EPA was primarily created due to many Americans concerns about the deterioration conditions of the water‚ air‚ and land. EPA has done a lot for this planet‚ but one of the main concerns that it still has to deal with is our air pollution. For many years‚ raw

Charcoal. Charcoal is one of the best substances to absorb smells. You will find that charcoal is used in many air and water filters. Grab a chunk of charcoal‚ the ones you use to grill will work fine‚ leave the charcoal in the car for a few days‚ and you will soon find the smells have gone away because they are absorbed into the charcoal. In this investigatory project its main purpose is to find out if how can charcoal be used as a filter and how does it work? Since charcoal is made out of carbon

Most of the gases and air pollutants are produced by burning fuels. Burning of coal produces carbon dioxide‚ sulphur dioxide etc. which are responsible for acid rain. Chlorofluorocarbons are widely used as propellants and as refrigerants which cause ozone depletion. Water pollution adversely changes the quality of water. It disturbs the balance of the ecosystem and causes health hazards. Water becomes polluted by the presence or addition of inorganic‚ organic or biological substances. Noise is also

The planet earth for millennia have offered mankind natural resources for its use. However‚ with the growth of the human population‚ resources have been used at a speed that is faster than it would take for it to be replaced. Such consumption has lead to many dangerous environmental effects. Problems like oil spills‚ loss of rain forests and acid rain are just some of the effects of such misuse of the earths natural resources. But‚ to bring about significant change to clean up oil spills‚ or to avoid

The Governments contribution to regulate air pollution The United States Government has enacted many polices to help recognize the major causes of air pollution today and what people can do to help clean the air. People finally have the ability to understand more reasonable responses to environmental contaminants and they provide a window into the impacts that the human race is having on the earth. One of the main causes of air pollution is manufacturing due to particular matter and chemicals

and can also impair the function of an airway. The largest quantity of NOx is emitted from road traffic and thus in the direct surrounding of the people. Especially in summer‚ these nitrogen oxides are the reason for formation of harmful to health ozone in near-ground layers. This nano-crystalline titanium dioxide is a photo catalyst. Activated by daylight the photo catalytic reaction results in oxidizing reagents converting hazardous NOx into harmless NO3 -. During sunny weather‚ the air can be cleaned
