The relationship between urinary BTEX metabolites and residence setting among Korean homemakers: the first Korea National Environmental Health Survey (2009–2011)

Annals of Occupational and Environmental Medicine, 2017
Background Benzene, toluene, ethylbenzene, and xylene (BTEX) are emitted in the combustion or volatilization of hazardous wastes and fossil fuels. Paint, varnishing agents, and cigarette smoke are also sources of BTEX in living environments.

Evaluation of Volatile Organic Compounds Levels inside Taxis Passing through Main Streets of Tehran

International Journal of Occupational Hygiene, 2015
Air quality inside commuting vehicles has seldom been evaluated in Iran. Accordingly, this study investigates the levels of benzene, toluene, ethylbenzene and xylene (BTEX) during workdays characterized by heavy traffic inside taxis in Tehran- Iran ...

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 ...

Distribution, Sources, and Environmental Impact Assessment of Monocyclic Aromatic Hydrocarbons (BTEX) in the Western South China Sea and the Pearl River Estuary

Progress in Fishery Sciences
Monocyclic aromatic hydrocarbons (MAHs), represented by benzene, toluene, ethylbenzene, m/p-xylene, and o-xylene (BTEX), are key components of volatile organic compounds (VOCs).

BTEX degradation in a cold-climate wetland system

Water Science and Technology, 2005
A pilot-scale subsurface vertical-flow wetland system was constructed at the former BP Refinery in Casper, Wyoming in order to determine benzene, toluene, ethylbenzene and xylene (BTEX) degradation rates in a cold-climate application. The pilot system, consisting of 4 cells, each dosed at a nominal flow rate of 5.4 cubic metres per day, was operated ...

BTEX removal with bioelectrochemical systems

, 2017
Benzene, toluene, ethylbenzene and xylenes (BTEX) are hazardous contaminants that can accidentally impact groundwater. Biological strategies can be used to remove BTEX compounds usually by adding oxygen to sustain the aerobic degradation. However, this approach can be expensive and technically difficult.
