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.

Global warming has become a problem of world wide, because it endangers living things. The consequences of global warming include the increase of the earth temperature and climate change. The increase of temperature (heating) in a city which is referred to urban heat island (UHI) is also the same problem in architecture. This research aimed to analyze the ambienttemperature of the UHI due to the motor vehicleactivities. Samples were taken from several locations: (1) Bahu Mall Parking area; (2) Manado Town Square 2 parking area; (3) along the Wolter Monginsidi street in front of Bahu Mall and (4) along the Piere Tendean street in front of Manado Town Square. This research used a quantitative method with a field survey. This research found that the ambient temperature increased when motor vehicles were stationary with engine on or moved. The temperature increased due to the heat from the engine and the reflection of the sun’s heat from the body of the vehicles. The heat level obtained from the survey was 34,8 0C to 39,4 0C. For this reason, a specific material for vehicle’s body is needed to prevent the increase of ambient temperature.

Introduction: Although many studies on Isfahan’s air pollution have been done, there is no report about the effects of cigarette consumption in Isfahan. The aims of this study were (a) to find the amount of nitrogen oxides, hydrocarbons, carbon monoxide and carbon dioxide emitted by cigarette consumption in Isfahan; and (b) to model the distribution of such pollutants in Isfahan’s atmosphere. Materials and methods: Based on the literature, it is assumed that 15% of Isfahan’s people consume cigarettes and each smoker on average smokes 1,147 cigarettes per year. Based on these assumptions, the 249,000 smokers living in Isfahan consume 285,000,000 cigarettes per year. The amount of pollutant emissions was calculated by existing emission factors for cigarette consumption. Finally, the distribution of the emitted pollutants from cigarette consumption in Isfahan’s atmosphere was modeled using AERMOD. Results: The results illustrated that each year, 2.85 kg nitrogen oxides, 2.85 kg hydrocarbons, 37.05 kg carbon monoxide and 142.5 kg carbon dioxide are emitted into Isfahan’s atmosphere from residents’ smoking. The modeling of pollutants’ dispersion in Isfahan’s atmosphere showed that only some of these pollutants result from cigarette consumption. Conclusion: This study demonstrated that the amount of pollutants emitted by cigarette consumption was negligible compared to the other pollutant sources in Isfahan.

Urban Stress

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.

Motor vehicles are the single largest source of toxic carbon monoxide in Karachi because advance emission control devices are not fitted in them mainly due to non-availability of low sulfur or sulfur-free fuel. On the contrary, commuters' exposure to carbon monoxide has not yet been investigated, while commuting in any motor vehicle of the city. Therefore, the present study investigated commuter's exposure to carbon monoxide, while travelling in nine different popular modes of transport. The exposure to CO concentrations was recorded inside the buses of seven standard routes of the city. Similarly, exposure to ambient carbon monoxide was also explored, while riding a motorbike on two different routes of the city. On an average, he came in contact with 6.82 ± 2.66 ppm CO during 7576 minutes travelling on nine routes of the metropolis. He was exposed to the highest CO concentration (15.20 ± 9.59 ppm), while riding a motorbike through Route 1 that passed through heavily populated neighborhood. Rider's exposure to carbon monoxide was found significantly (p < 0.05) correlated with wind velocity. As a whole, commuter's exposures to carbon monoxide during evening was significantly (p < 0.01) higher than those of the morning sessions. The present study will provide baseline information for reducing human exposure to the deadly carbon monoxide.

Now a days the global warming and air pollution are big issue in the world. The more amount of air pollution is due to emissions from an internal combustion engine. Catalytic converter plays a vital role in reducing harmful gases. In this study, the nanocoated catalytic converter efficiency was focused. The flow area of catalytic converter plays a vital role in the conversion of the harmful gases NOx, CO & UHC. The wire mesh coated with Alumina and Ti02 was the conversion medium. By varying the length of the wire mesh, the flow area was changed. The length of the wire mesh substrate was varied by 100mm, 150mm and 200mm. It was experimentally found that the increase in flow area reduces the exhaust emissions smoke, CO, HC and NOx.

The increasing number of motorized vehicles has a direct impact on exhaust gas air pollution. The air pollution in urban areas is dominated by motorized vehicle emissions, along with pollution problems. This study aims to reduce motor vehicle emissions by using a catalytic converter design made from a brass plate catalyst in the shape of a honeycomb. Honeycomb-shaped brass is suitable for catalysts in the catalytic converter. Besides being easy to obtain and cheap in price, the catalyst can reduce and oxidize exhaust gases well, making it suitable as a catalyst material. The method used in this research is the experimental method. It is started from the design of the catalytic converter house and determining the type of catalyst to the process of making the catalytic converter with a honeycomb-shaped brass plate. Then, testing to determine the emission of exhaust gases produced is required. The last step is to compare it without using a catalytic converter or standard conditions. From the results of the emission test, it was found that the use of a catalytic converter made from a brass plate catalyst in the shape of a honeycomb can reduce HC and CO emissions, while CO2 emissions have increased. A decrease in HC gas emissions by 19.1% for a single catalytic converter and 33.7% for a dual catalytic converter is better compared to without using a catalytic converter or standard conditions. Reduced CO gas emissions by 23.8% for a single catalytic converter and 43.1% for a dual catalytic converter are compared to without using a catalytic converter. Meanwhile, CO2 gas emissions increased by 60.7% for a single catalytic converter, and 81.6% for multiple catalytic converters are compared without using a catalytic converter. This is a result of the addition of oxygen to the oxidation process that running smoothly.
