In this research, gasoline vapours including Benzene, Toluene, Xylene (BTX) and Total Volatile Organic Compounds (TVOCs) emitted from vent pipes of underground storage tanks (USTs) were measured at six gas stations in Tehran. Thereafter, gas station No. 29 was selected as a pilot station and equipped with a vapour control system. The vapours were measured during the summer of 2013 and winter of...

background: gasoline station workers are exposed to volatile organic compounds such as benzene, toluene, ethylbenzene and xylene (btex). objectives: to determine the level of exposure to btex compounds among gasoline station workers and measure the roadside concentrations of these compounds in the inner and outer areas of bangkok, thailand. methods: 49 workers at 6 gasoline stations in the inne...

Owing to the unreasonable layout problem and the excessive number of gas station in some regions of China, this paper attempts to discuss the principle of rationality and related factors for the gas station layout. In determining the relationship between the number of stations and motor vehicle demand, this paper simulates the vehicle’s selection of price by using Starlogo simulation platform. ...

This paper presents the insights of imbalanced public bicycle distributions, i.e. unable to pick up/return bikes due to empty/full stations through the analysis of spatio-temporal activity patterns of bike stations. YouBike, the public bikesharing system of Taipei City was examined. Taking advantage of Open Data policy, the changes of the number of available bikes across all stations were colle...

background : the aims of this study were evaluation of exposed to xylenes in low concentration and compare urinary level of methyl hippuric acid in taxi drivers and petrol stations workers in west of iran. methods: this observation study was carried out on samples of the exposed men to xylenes in two occupational groups in hamadan city (west of iran) from march 2003 to march 2004. subjects incl...

Soil temperature (tB) was determined down to 2 m below ground level at 8 locations in the city of Oberhausen, Ruhr area, Germany, between August 2010 and July 2011 to investigate the subsurface urban heat island (SUHI) and its impact on drinking water quality. The soil temperatures obtained in Oberhausen demonstrate typical location-dependent behaviour. At the depth of drinking water pipes (1 t...
