OPTIMIZING BTEX BIODEGRADATION UNDER DENITRIFYING CONDITIONS [PDF]
Environmental Toxicology and Chemistry, 1991 Abstract Laboratory tests were conducted to determine optimum conditions for benzene, toluene, ethylbenzene, and xylene (collectively known as BTEX) biodegradation by aquifer microorganisms under denitrifying conditions. Microcosms, constructed with aquifer samples from Traverse City, Michigan, were amended with selected concentrations ...

Urban BTEX Spatiotemporal Exposure Assessment by Chemometric Expertise [PDF]
Water, Air, & Soil Pollution, 2013 Normative regulations on benzene in fuels and urban management strategies are expected to improve air quality. The present study deals with the application of self-organizing maps (SOMs) in order to explore the spatiotemporal variations of benzene, toluene, ethylbenzene, and xylene levels in an urban atmosphere.
