Abstract The paper describes the observational and modeling efforts performed under Bolzano Tracer Experiment (BTEX). BTEX focused on basin surrounding city of Bolzano, at junction three tributary valleys southern side Alps, to characterize ground-level impact pollutants emitted by a waste incinerator close city, atmospheric factors controlling dispersion processes in whole basin, different win...

Abstract Exposure to benzene and other volatile organic compounds (VOCs) like toluene, ethylbenzene, o -, m p -xylene (BTEX) at a fuel station is hazardous for the workers. This study aims estimate health risk worker due exposure of BTEX after implementation vapour recovery system (VRS) stations. Air samples were collected using low-flow sampling pump as per NIOSH method by Tenax (sorbent) tube...

Understanding the fate and transport mechanism of petroleum hydrocarbons (PHC) in groundwater is critical after their spill is critical towards complete removal of contaminants from the aquifer. Even though the effective solubilities of benzene, toluene, ethylbenzene and xylene (BTEX) compounds in the mixture are lower than their pure phase aqueous solubilities, they can persist in the aquifer ...

BACKGROUND Hazardous air pollutant exposures are common in urban areas contributing to increased risk of cancer and other adverse health outcomes. While recent analyses indicate that New York City residents experience significantly higher cancer risks attributable to hazardous air pollutant exposures than the United States as a whole, limited data exist to assess intra-urban variability in air ...
