The job of our ozone is to protect the Earth from UV light radiation from the sun. Jonathan E. Hickman‚ Shiliang Wu‚ Loretta J. Mickley‚ and Manuel T. Lerdau (2010) believe that the spread of Kudzu has the potential to raise ozone levels (this would be bad) by the emission of nitric oxide. Hickman and company created a study that observed the effect of kudzu on trace gas

In a nutshell‚ generally all of us know that earth’s ozone layer is decreasing. There is nothing new here but if we follow at least some of these tips‚ we can be proud of ourselves by participating in the protection of the environment.

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 by photo

Cities like Los Angeles‚ New York‚ Sydney‚ and Vancouver frequently suffer episodes of photochemical smog. One way in which the production of photochemical smog is initiated is through the photochemical reaction of nitrogen dioxide (NO2) to form ozone. There are many sources of photochemical smog‚ including vehicle engines (the number one cause of photochemical smog)‚

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
