Laboratory Assessment of BTEX Soil Flushing

Environmental Science & Technology, 1996
Soil cores from the unsaturated zone of a waste site contaminated with benzene, toluene, ethylbenzene, and xylenes (BTEX) were flushed with water under conditions representative of those proposed for site remediation. With a laboratory column dispersivity of 1 cm, kinetic modeling of the breakthrough curves gave desorption rate constants of 0.01−0.1 h ...

Anoxic biodegradation of BTEX in a biotrickling filter

Science of The Total Environment, 2017
Emissions of BTEX (benzene, toluene, ethylbenzene and xylene) from the petrochemical industry are characterized by a low pollutants concentration and the absence of oxygen. Biodegradation of these pollutants using nitrate as the electron acceptor is of key interest to reuse the residual gas for inertization purposes.

Sectoral Analysis of BTEX Exposure Data

2022
Benzen, toluen, etil benzen ve ksilen (BTEX) havadaki önemli toksik uçucu organik bileşiklerdendir. Kapalı çalışma ortamında boyalar, çözücüler, yapıştırıcılar ve temizlik maddeleri gibi çeşitli emisyon kaynaklarına sahiptirler. Ortama salındıklarında hızlı bir şeklide havaya karışırlar ve vücuda solunum yoluyla kolayca girebilirler.

BTEX catabolism interactions in a toluene-acclimatized biofilter

Applied Microbiology and Biotechnology, 2001
BTEX substrate interactions for a toluene-acclimatized biofilter consortium were investigated. Benzene, ethylbenzene, o-xylene, m-xylene and p-xylene removal efficiencies were determined at a loading rate of 18.07 g m(-3) h(-1) and retention times of 0.5-3.0 min.

Katalitička oksidacija BTEX u monolitnom reaktoru

2019
Environmental pollution is a problem that is getting more and more attention nowadays. Due to the sudden industrial development and the increasing intensity of anthropogenic activities there is an increasing number of pollutants in the environment. Volatile organic compounds, which under normal pressure and temperature conditions easily evaporate, are ...
