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.

Main Component

Malaysia is reported to experience explosive rise in the demand of transport vehicles in recent years due to rapid economic development and population growth. As a result, air pollution is expected to increase in conjunction with the increase in the number of the vehicles.  In particular, Carbon Monoxide (CO) has been identified as the main component of the emission sources from vehicles other than Nitrogen Oxide (NOx), hydrocarbon lead and particulate matter of size less than 10 micron (PM10).  This provides the reason why CO concentration is often used to reflect traffic density in an area. CO has both short-term and long-term effect on human’s health. Thus, knowledge on CO behaviour and the future levels at an area is important to help decision makers in managing air pollution due to vehicles emission in the country. This study was conducted to describe CO data and to determine a suitable time series model to enable the prediction of CO levels at two industrial sites; Perai and Pasir Gudang, Malaysia. The model obtained could help management to mitigate CO pollution at the sites. The analysis was conducted using daily maximum data which was obtained from the Department of Environment Malaysia from 2010 to 2014. The performance of the best model was determined using several performance measures such as MAE, RMSE and MAPE.   The study has found that the most appropriate time series model for Perai is ARIMA (3,1,1) and for Pasir Gudang is SARIMA (2, 1, 8) (1, 1, 2)7.

Public Attention

Air pollution generated from motor vehicle exhaust has become a major cause for scientific and public concern worldwide over recent years. The rapid and marked increase in the motor vehicle traffic and its associated emissions in urban areas have paralleled a sharp increase in the prevalence of allergic diseases such as asthma and rhinitis. Epidemiological studies have demonstrated a strong association between people living in close proximity to roads with high traffic density and increased allergic symptoms, reduced lung function and increased sensitization to common aeroallergens. Several laboratory-based studies have demonstrated that pollutants emitted from motor vehicles can induce allergic inflammation and increase airway hyperresponsiveness, which may provide an underlying mechanism for the increasing prevalence of allergic diseases. Although the detrimental effects of air pollution on human health have been brought to public attention, it appears that less attention has been given to the potential role of road traffic fumes in the induction of the allergic state. Legislators should consider pollutants emitted from motor vehicle exhausts as a potential pro-allergic hazard, before making important changes in environmental policy.

Potential hazards that often occur in underground tunnels are dangerous and toxic gases, one of which is carbon monoxide (CO) which can be found in underground tunnels for example as a result of imperfect detonation on work surfaces. CO gas is very poisonous so it can cause death. This study aims to determine the spread of CO gas when diluting with tunnel ventilation in the horizontal front. This research was conducted on a physical model of the laboratory with a ratio of 1:10 compared to the actual tunnel, that is at the cross section of the model in the laboratory 40 cm x 40 cm. The effectiveness of dilution or dilution is indicated by the value of the diffusion coefficient, where the greater the diffusion coefficient, the more diffused the CO gas concentration, so the faster the CO gas concentration decreases. The parameters of the test conditions are the ratio of the duct to face distance (L/D) and the Reynolds number (Re) which shows the variation of air velocity in the tunnel work surface. Test results from the distribution of CO gas showed the influence of the configuration of the forcing duct and exhausting duct distances on the working front to the CO gas dilution. In this study also found the influence of Reynolds numbers on the value of the diffusion coefficient, that the greater the value of Re, the greater the value of E.

Co Gas

The chemical compound of CO gas is a gas that has no color and contributes greatly to environmental pollution as a result of incomplete combustion of fuel produced from motor vehicles. Carbon monoxide is very dangerous (toxic, so it is often referred to as the "silent killer". The presence of CO gas will be very dangerous if inhaled by humans because the gas will replace the position of oxygen that binds to hemoglobin in the blood. The purpose of the study was to identify the presence or absence of carbon monoxide (CO) in the blood of fruit sellers at the Sungguminasa Twin Bridge. This research is an analytical observational field research using the alkaline dilution test method. The sampling technique used purposive sampling with the criteria of working more than one year, working 8 hours a day and not smoking. The number of samples used as many as 9 samples of venous blood. From the results of this study, it can be concluded that the presence of carbon monoxide gas was not identified in all blood samples of fruit sellers at the Sungguminasa Twin Bridge. This is because in the alkaline dilution test method, CO gas can only be identified with saturation levels above 20%.

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.
