Traffic is a major contributor to this. Car engines pollute our air with nitrogen oxides, carbon monoxide, sulphur dioxide and particulate matter. Studies have shown that the air we breathe is contaminated with particulate matter and nitrogen oxides, which damage our health. Nitrogen oxides are particularly harmful for human beings and the environment, as the gas nitrogen dioxide is an irritant that attacks the mucous membranes and leads to inflammation of the respiratory tract and lungs. Nitrogen oxides play a central role in the formation of low-lying ozone and acid rain. CLEAN AIR IS A CIVIL RIGHT! Keeping our air clean is one of the most urgent challenges facing towns and communities in particular. There have been detailed discussions about banning vehicles as a way to reduce nitrogen oxides and these types of ban have already been introduced in some areas. But, by themselves these new traffic regulations alone will not be enough to solve the problem. "We cannot solve our problems with the same thinking we used when we created them." Albert Einstein "PHOTOCATALYSIS" – A NEW APPROACH TO THE PROBLEM Advances in technology are providing new solutions to environmental problems. The principle of photocatalysis offers an innovative approach to reduce pollutants such as nitrogen oxides in the air.
