Executive Summary: In this project our group set out to determine what effect, if any, an air monitor's distance from the roadway had on the measured air pollution levels of carbon monoxide, nitrogen dioxide, and fine particulate matter (PM2.5). The group was also searching to see if we could identify pollution emitters using wind data. "Fine particles," such as those found in smoke and haze, a...
Traffic noise has become more and more serious in city ambient noise than ever. The paper presents a new method on the evaluation of city ambient noise. Road traffic noise calculation model and railway noise calculation model is given in this paper. Now the method has been testified in the evaluation in some newly built residential area in Beijing. 1 INTRODUCTION In all kinds of city ambient no...
The paper evaluates the contents of total forms of selected heavy metals (Zn, Cu, Ni and Pb) as well as the activity of catalase (CAT), dehydrogenases (DEH), alkaline phosphatase (AlP) and acid phosphatase (AcP) in mineral surface horizons of forest soils exposed to the effect of road traffic pollutions. The sampling locations (n = 24) were determined in the area covered by the Szubin Forest al...
background: although lebanon is a highly polluted country, so far no study has specifically been designed to assess the association between outdoor air pollution and chronic bronchitis in this country. objective: to assess the association between exposure to outdoor air pollution and chronic bronchitis in lebanon. methods: a pilot case-control study was conducted in two tertiary care hospitals....
plant pollution from lead produced by automobile exhaust system near 'certain high ways of iran
plants polluted with pb produced by automobiles along the roads and highways have extensively been reported all over the world. it is the most important source of pollution in the environment. this research was carried out to determine the polluting degree of plants along the highways such as: rasht-anzaly, kelachay-ramsar, tehran-karaj, and isfahan-tehran. at each arbitrary point, a transect 1...
BACKGROUND Traffic-related air pollution is a potential risk factor for human respiratory health. A Geographical Information System (GIS) approach was used to examine whether distance from a main road (the Tosco-Romagnola road) affected respiratory health status. METHODS We used data collected during an epidemiological survey performed in the Pisa-Cascina area (central Italy) in the period 19...
Rapid growth in economies and a sharp increase in the present quantity of vehicles have contributed to congested cities, traffic accidents, energy crises and air pollution, which not only cause serious economic damage but also affect human life and safety. According to the Kyoto Protocol international standards and consensus, the trend in the automotive industry is to develop more ecological ve...
One proposed method for reducing exposure to mobile source air pollution is the construction or preservation of vegetation barriers between major roads and nearby populations. This study combined stationary and mobile monitoring approaches to determine the effects of an existing, mixed-species tree stand on near-road black carbon (BC) and particulate matter concentrations. Results indicated tha...
Abstract Background: One of the major challenges in road safety is the occurrence of sudden disability attacks while driving. An important point about the occupational health of drivers who have patients who have the potential for sudden disability attacks is to estimate the likelihood and consequences of the attacks. In other words, how likely is an accident to follow a sudden disability while...
