Among air pollution control strategies, air cleaning with Advanced Oxidation Processes (AOPs) has been drawing more and more attention because of the restraints in the production of secondary pollution. AOPs have a wide range of applications such as air (odour elimination, purification), soil (remediation) and water decontamination. Ideally, the photo catalyst, titanium dioxide, is introduced in the top layer of the concrete pavement for best results. In addition, the combination of TiO2 with cement-based products offers some synergistic advantages, as the reaction products can be adsorbed at the surface and subsequently be washed away by rain. The main aim of this research work is to measure the effect of titanium dioxide as photo catalyst in purifying nitrogen oxide (NOX) and Carbon Oxides (COX) on pavement surface and outdoor environment condition. For that, TiO2 is replaced for cement at different proportions of 5%, 10% & 15% in terms of weight in the cement concrete moulds of 10 mm uniform thickness and curing is done for seven days, then same were exposed to the sunlight at Ijoor circle sampling point Rama Nagar Town for 21 days of observation. From the Energy Dispersive Spectroscopy (EDS) analysis, result it is observed that atom percentage increased maximum of 59.05 for carbon atoms for 10% proportion specimen. Then, check the amount of percentage for carbon atoms adsorbed by 10% proportion specimen at police/Kandaya Bhavan circle and Railway station circle sampling points of Rama Nagar Town for 21 days of observations and the results shows that, carbon atom percentage increased maximum of 42.99 and 58.69 for carbon atoms respectively at above sampling points. From this work, it is conclude that the Carbon atoms and Nitrogen atoms present in the atmosphere will be reduce up to some level when replace 10% of Titanium dioxide with cement in the concrete moulds of 10 mm thickness by Photo catalytic activity.

Soots obtained from various sources are formed due to incomplete combustion of fossil fuels, bio-fuel, and biomass. It is emitted in both anthropogenic and naturally occurring partially burned emissions. Carbon soot (CS) consists of fine carbon particles and adsorbed components on their surface. It is formed from the aliphatic and aromatic compounds which undergo certain reactions such as pyrolysis and oxidation. The Black Carbon of soot consists of pure carbon linked in several forms. These particles can have different types of morphologies, but the basic unit of it is agglomerated carbon particle which are, rough and spherical within the size range 0.01 to 0.05 µm. Various reactions like condensations, fragmentation, of aliphatic and aromatic hydrocarbons, at high temperatures in the presence of adequate oxygen with the C/H ratio at-least or above the threshold value of 1-2 to form poly aromatic hydrocarbons (PAHs) contributes towards their formation and during this soot nuclei grow to form larger soot particles. Various biological systems including human beings are badly affected if exposed to CS. Smaller particles (sizes 1/30 th of human hair) can easily enter the respiratory tract and cause diseases like: cancer and asthma. They are also the second largest contributor for global warming and acid rains causing a variety of detrimental environmental impacts on agriculture, forests, animal ecosystems and human made structures. The present study describes the impact of carbon soot on human health and other ecological systems.
