Topic of this paper is air pollution as a cause of urban stress. This problem is analyzed within a case study in Bulevar Nemanjica in Nis. For the observed location, the measurements were conducted in a period of eight months (May 2007 - June 2007) by the Health Protection Institute in Nis. Motor traffic exhaust gases which were observed were: carbon-monoxide (CO), nitro-oxide (Nox) formaldehyde (HCHO). Measurements were taken at "Bulevar" green market, b standard methodology prescribed by the boundary values code book, immision measurement method, criteria for creation of measuring points and data records. Concentration of exhaust gases of motor vehicles did not exceed permissible limits, except carbon monoxide in May, while it continued to decrease and remained within the legal limits. If the Mediana - Bulevar Nemanjica location was enriched by green surface and pedestrian zones, this would lead to the decrease of exhaust gases concentration. That would prevent endangering environment and facilitate its healthy functioning.

A new type of catalysts not containing noble metal oxides have been developed and the possibilities of their application both for the complete neutralization of carbon monoxide in exhaust gases and the process of deep oxidation of volatile hydrocarbons are studied. It has been foundthatthe activity of catalysts based on vanadiumandphosphorus oxides supported on Al2O3, SiO2, TiO2by and their modification withof 1–3% oxides of Cu, Cr, Co, Zn enhanced the conversion of the deep oxidation process to 95–100% at the temperatures of 673–693K and volumetric velocities of 5000–10000 h–1. During the simultaneous oxidation of CO and C3H8at a CO conversion of 90%, the C3H8conversionwas 70%. It has been established that oxidation of CO and C1–C4 hydrocarbons, and especially propane, with the participation of synthesized catalytic series, occurs by stepwise and associative mechanisms. The oxidation of CO and C3H8required a high oxygen content of 1:20–25 mol. Besides utilizing carbon monoxide in exhaust gases from motor vehicles, these catalytic systems can be successfully used to neutralize industrial gases, especially those emitted from oil refineries and thermal power plants. Preliminary research has shown that these catalytic systems can operate for about 50000 hours without changing the activity.

The pollutants emitted in the surroundings of motor vehicle exhausts vary according to the type of engine cycle, the use of fuel and the use of catalytic converters. Harmful compounds emitted from internal combustion engine exhaust (IYM) exhausts; HC Hydro Carbon, CO Carbon Monoxide, NOx Nitrogen Oxides and Particulate substances. Without the Catalytic Converter, the pollutant value of a motor vehicle operating with the Otto cycle and using gasoline is the highest. Diesel Motor Vehicles, which work with the Diesel cycle later, are the cleanest of these vehicles, which use the Otto cycle and use LPG. It is estimated that more than half of the polluters that lead to air pollution in large cities come from exhausts of motor vehicles. HC Hydrocarbons cause cancers in living things, CO poisoning carbon monoxide living things, causing deaths in case of excessive respiration. NOx Nitrogen Oxides disrupt the balance of nature as acid rain. CO2, which is thought to cause less damage, causes greenhouse effect in the atmosphere, causing the climate to change and the average temperature to increase. This study is to examine the effects of air pollution caused by exhaust gases on domestic pets, plant cover and water and other environment in the city.

Traffic jam makes cities less pleasant for living and it also decreases traffic efficiency whereas travel time, fuel consumption and drivers’ stress are increased. A special problem is its influence on people’s health caused by emission of exhaust gases. Emission of pollutants originating from mobile sources is primarily conditioned by a level of technologies applied to the vehicle, vehicle’s technical state, traffic intensity, traffic density, local climate conditions, etc. Air pollution due to use of motor vehicles is becoming one of the major problems in urban areas across the world. With the increase of the number of motor vehicles and traffic intensification, the influence of exhaust gases on human environment also has increased. Considering the average age of the vehicles participating in traffic in the city of Kragujevac and the traffic capacity of traffic arteries, most frequently not designed for such a large number of vehicles concentrated at the core of the city, it is to be expected that the air pollution coming from mobile sources will become a problem that requires detailed analysis. For that purpose, a detailed statistical analysis of the vehicle fleet of the city of Kragujevac is conducted. An estimation of the influence of the vehicles on the air pollution in the city of Kragujevac, has been given in the paper.

Levels of many outdoor air pollutants decreased substantially after the passage of the Clean Air Act of 1970; however, levels of ozone, carbon monoxide, and particulate matter are still high enough to present hazards to children. Failure to meet the federal standards for these pollutants was a major force driving the adoption of the revised Clean Air Act of 1990. In addition, recent research indicates that acidic aerosols, for which there are no health-based standards, may be associated with adverse respiratory effects. As an ambient air pollutant, ozone is formed by the action of sunlight on nitrogen oxides and reactive hydrocarbons (both of which are emitted by motor vehicles and industrial sources). Ozone levels therefore tend to be highest on warm, sunny days, which are conducive to outdoor activities. In many areas ozone concentrations peak in the midafternoon, when children are likely to be playing outside. It is important to distinguish ground-level ozone air pollution from stratospheric ozone depletion by chlorofluorocarbons. These issues are unrelated. Carbon monoxide, a product of incomplete combustion, is emitted mainly from cars and other mobile sources. Airborne particulate matter is a variable and complex mixture of natural materials and substances released from numerous industries, motor vehicles, residential wood burning, construction and demolition, and other sources. Acidic aerosols are traceable mainly to combustion of sulfur-containing fossil fuels and to reactions of photochemical free radicals with nitrogen dioxide. Exposure to ambient air pollution in North America has been clearly associated with acute and subacute effects in epidemiologic investigations and in controlled exposure studies in environmental chambers.
