Application

1,2,3,4-tetrachlorobenzene was used as a model compound to determine the chlorobenzenes (CBs) in soil samples. It was also used for rapid dechlorination of 1,2,3,4-tetrachlorodibenzo-p-dioxin (1,2,3,4-TeCDD).

Dechlorination of spiked 1,2,3,4-tetrachlorodibenzo-p-dioxin (1,2,3,4-TeCDD) was investigated in sediment microcosms from three polychlorinated dibenzo-p-dioxin and dibenzofuran (CDD/F)-contaminated sites: River Kymijoki, Finland; Gulf Island Pond, Maine; and Lake Roosevelt, Washington. Dechlorination was stimulated by addition of electron donor and halogenated priming

A novel and simple analytical method for the determination of chlorobenzenes (CBs) in soil samples was developed using ultrasonic-assisted water extraction (UAWE) coupled with solvent bar microextraction (SBME). Four chlorobenzenes, 1,2,3-trichlorobenzene (1,2,3-TCB), 1,2,3,4-tetrachlorobenzene (1,2,3,4-TeCB), hexachlorobenzene (HCB), and 1-chloro-4-nitrobenzene (1-C-4-NB), were

A vial equilibration technique was used to estimate the fugacity capacities of food and feces samples for 1,2,3,4-tetrachlorobenzene (TCB). The method was calibrated using different volumes of n-octanol and by comparing the measured and predicted fugacity capacity (Zoct) of n-octanol
