Urban ambient air concentrations of 39 aromatic (including benzene, toluene, and xylenes) and aliphatic volatile organic compounds (VOCs) were measured in Yokohama city, Japan. Yokohama city was selected as a case study to assess the amount of VOC released from Industrial area to characterize the ambient air quality with respect to VOC as well as to know the impact of petrochemical storage faci...

This paper examines the significant differences in seasonal variations of air pollutants concentrations at urban, industrial, commercial and agricultural areas of Uttarakhand. PM10 (RSPM), suspended particulate matter (SPM), sulphur dioxide (SO2) and oxides of nitrogen (NOx) were collected over four sites in Haridwar and Dehradun Valley, Uttarakhand. The first one, Shivalik Nagar, Haridwar is a...

Urbanization is developing unprecedentedly on a global scale. One of the chief repercussions of urbanization, caused by man-made alterations in land-use/land-cover (LULC), is the formation of urban heat islands. Albeit, differences among landscape structures and its accompanied effects on the environment are mostly neglected. Accordingly, the main objective of this study is to survey the variou...

Fine airborne respirable particulates less than 10 micrometer (PM10) are considered one of the top environmental public health concerns, since they contain polycyclic aromatic hydrocarbons (PAHs) which are among the major carcinogenic compounds found in urban air. The objective of this study is to assess the genotoxicity of the ambient PM10 collected at 11 urban sites in Jeddah, Saudi Arabia. T...

BACKGROUND The positive matrix factorization is a powerful environmental analysis technique which has been successfully utilized to assess air-born particulate matter source contribution. The new version of this model (PMF5) has two additional estimation error methods and some other useful advantages compared to the previous versions. In the present study, the capability of PMF5 for identificat...

Energy consumed the in urban sector accounts for a large proportion of total world delivered energy consumption. Residential building energy consumption is an important part of urban energy consumption. However, there are few studies focused on this issue and that have simulated the energy consumption of residential buildings using questionnaire data. In this research, an eQUEST study was condu...

Numerous surveys have demonstrated that diffuse pollution from urban-residential run-off and industrial discharges can adversely impact salt marsh and tidal creek sediment quality (Barrett & McBrien, 2006; Fox et al., 2001; Iannuzzi et al., 1995; Long et al., 1995; Sanger et al., 2004; White et al., 2005). The impact of shipping activities, including major discharge of fuel oil onto salt marshe...
