The indoor and outdoor particulate concentration and its chemical composition in six monitoring stations and selected residential dwellings were studied in May 2010 in Kathmandu valley. The six stations were strategically located to measure the air quality of the valley viz. -urban roadside, urban hospital, urban residential, urban background and valley background. Particulate concentration was...

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...

VANETs, as a subset of the MANETs, have progressed remarkably in recent years. These networks have an important role in improving traffic, road safety and driver service. In vehicle Networks, vehicle can Communication by vehicle-to-vehicle communication. Since there are fewer vehicles in the environment, there is no vehicle-to-vehicle connection in some areas. Therefore, they use Road Side Unit...

Combustion-derived black carbon has received attention as a form of refractory organic carbon that may be preferentially preserved in soils and sediments. However, little is understood about the environmental roles of black carbon in urban soils. This investigation represented the preliminary study to characterize black carbon (BC) concentrations and enrichment ratios in Xuzhou urban roadside t...

BACKGROUND Roadside pedestrian injuries represent a significant portion of trauma team activations, especially at urban trauma centers. Patient demographics and severity of injury vary greatly in this patient population. Herein, we hypothesize that injury patterns may be predictable, especially with respect to age. MATERIALS AND METHODS All patients with roadside pedestrian injuries evaluated...

Vegetation as an essential positive sustainable element of urban spaces has recently gathered increased attention from landscape architects and urban planners. Vegetation growing in urban settings can bring environmental benefits that enhance the health and well-being of citizens through, for example, improved air quality, increased thermal insulation for buildings, reduction of the urban heat-...

Nowadays urban pollution exposure from road transport has become a great concern in major cities throughout the world. A modelling framework has been developed to simulate Personal Exposure Frequency Distributions (PEFDs) as a function of urban background and roadside pollutant concentrations, under different traffic conditions. In this paper, we present a technique for classifying roads, accor...

Understanding the responses of species and ecosystems to human-induced global environmental change has become a high research priority. The main aim of this thesis was to investigate how certain environmental factors that relate to global change affect European aspen (Populus tremula), a keystone species in boreal forests, and hybrid aspen (P. tremula × P. tremuloides), cultivated in commercial...

A quantitative microbial risk assessment was applied to evaluate the microbial risks of the Accra Urban Water System (AUWS). The exposure assessment was based on the count of indicator organisms in waste water from open roadside drains and in water and sand samples from the beach. The predicted total disease burden generated in a representative catchment of the AUWS (Odaw Catchment) was 36,329 ...
