Analysis of chlorobenzenes in sewage sludge by capillary gas chromatography

, 1991
An analytical method has been developed to investigate the occurrence of chlorobenzenes in sewage sludge. Sewage sludge was centrifuged, dewatered, Soxhlet extracted, cleaned and analysed by capillary gas chromatography using two columns with different ...

The Role of Uron and Chlorobenzene Derivatives, as Potential Endocrine Disrupting Compounds, in the Secretion of ACTH and PRL

International Journal of Endocrinology, 2018
Uron herbicides polluting the environment represent a serious concern for environmental health and may be regarded as endocrine-disrupting compounds (EDCs), which influence the regulation of human homeostasis.

Impact of soil depth on the dissipation of chlorobenzenes

, 2013
The fate processes of volatilization and biodegradation were quantified in an aerobic batch experiment for the chlorobenzenes (CBs): 1,2-dichlorobenzene (DCB), 1,2,3-trichlorobenzene (TCB) and hexachlorobenzene (HCB) in soil sampled from different depths:

Phytoremediation of chlorobenzenes in sewage sludge cultivated with Pennisetum purpureum at different times

Revista Brasileira de Engenharia Agrícola e Ambiental
One of the major limitations of sewage sludge agricultural use is the presence of chlorobenzenes (CBs), which are toxic to the environment. The use of techniques of sewage sludge phytoremediation can be an important alternative for the degradation of ...

Dioxin formation during biogas utilization from anaerobic digestion of food waste: Potential role of non-methane volatile organic compounds

Fuel Processing Technology
While chlorinated volatile organic compounds (VOCs) are often considered dioxin precursors, the formation pathways of dioxins during biogas combustion from food waste anaerobic digestion plants remain poorly understood.

Formation of chlorobenzenes by oxidative thermal decomposition of 1,3-dichloropropene [PDF]

, 2015
We combine combustion experiments and density functional theory (DFT) calculations to investigate the formation of chlorobenzenes from oxidative thermal decomposition of 1,3-dichloropropene. Mono- to hexa-chlorobenzenes are observed between 800 and 1150.
