Poorly maintained roads are a fact of life in most developing countries; it is certainly the case in Sri Lanka. The lack of funding to maintain the road surfaces is a main reason for the dilapidated condition of roads in these countries, but it is not the only reason. The absence of an effective monitoring system is one reason for this problem. A monitoring system can help to take remedial acti...

background: sound produced by the passing traffic contributes to noise pollution. noise pollution affects the residents of both city and suburban areas. the noise produced does not only disturb the community living nearby the main road during the day but becomes worse during the night. the purpose of the study is to perform noise level measurement and subjective evaluation on the noise produced...

Widespread and increasing use of road deicing salt is a major driver lake chloride concentrations, which can negatively impact aquatic organisms ecosystems. We used simple model to explore the controls on concentrations predict equilibrium in lakes across contiguous United States. The suggests that concentration depends three quantities: application rate, density, runoff (precipitation minus ev...

BACKGROUND There is relatively little evidence of health effects of long-term exposure to traffic-related pollution in susceptible populations. We investigated whether long-term exposure to traffic air and noise pollution was associated with all-cause mortality or hospital readmission for myocardial infarction (MI) among survivors of hospital admission for MI. METHODS Patients from the Myocar...

Roads form vast, pervasive and growing networks across the Earth, causing negative environmental impacts that spill out into a ‘road-effect zone’. Previous research has estimated regional global extent of these zones using arbitrary distances, ignoring spatial distribution distance-dependent attenuation different forms road impact. With Great Britain as study area, we used mapping roads realist...

Considerable interest has focused on levels of exhaust emissions in the cabins of diesel-powered school buses and their possible adverse health effects. Significantly different policy and engineering issues would be raised if compelling evidence found that inc-cabin contamination was due to self-pollution from bus emissions, rather than ambient pollution, neighboring vehicles, and/or re-entrain...
