Biotransformation of trichloroethene by pure bacterial cultures
Folia Microbiologica, 2002From natural samples 11 isolates able to remove trichloroethene (CCl2CHCl) from an aqueous environment were obtained which were capable of cometabolic degradation of CCl2CHCl by an enzyme system for phenol degradation. At an initial CCl2CHCl concentration of 1 mg/L, the resting cells of particular cultures degraded 33-94% CCl2CHCl during 1 d and their ...

Adsorption of Trichloroethene at the Vapor/Water Interface
Environmental Science & Technology, 2000Aqueous solution surface tension (pressure) as a function of vapor-phase trichloroethene (TCE) pressure isotherms were measured at atmospheric pressure at 287.2, 291.2, 297.2, 303.2, and 315.2 K using a flow-through vapor adsorption method. Solute (i.e., TCE)-induced surface tension variations were quantified using Axisymmetric Drop Shape Analysis ...

Sorption equilibria for trichloroethene on algae
Water Research, 1990Abstract The sorption of chlorinated solvents by algae can remove the solvents from natural waters and wastewaters treated in stabilization lagoons and other phototrophically active treatment processes. The equilibrium sorption of 14 C-labeled trichloroethene (TCE) to three species of algae— Chlorella vulgaris , Scenedesmus quadricauda and ...

Sulfidation of Magnetite for Superior Dechlorination of Trichloroethene
Environmental Science & TechnologyThe reported contributions of magnetite to the abiotic natural attenuation of chlorinated ethenes have generated interest in its potential for soil and groundwater remediation. In this study, we investigated the impact of the two-step sulfidation method on the physicochemical properties and reactivity of magnetite with trichloroethene (TCE).

Sorption of trichloroethene onto stylolites
Journal of Contaminant Hydrology, 1999Abstract Batch and double reservoir diffusion cell experiments are used to investigate sorption of trichloroethene onto stylolites. Stylolites are common features in carbonate rock formations, and might contain high amounts of organic matter. Due to the hydrophobic character of TCE, its transport in fractured carbonate aquifers could be significantly

Remediation of BTEX and trichloroethene
Environmental Science and Pollution Research, 2002The widespread use of industrial chemicals in our highly industrialized society has often caused contamination of large terrestrial and marine areas due to the deliberate and accidental release of organic pollutants into the soil and groundwater. In this review, environmental problems arising from the use of chlorinated solvents and BTEX compounds are ...

Application of the Benchmark Method to Risk Assessment of Trichloroethene
Regulatory Toxicology and Pharmacology, 1995An alternative approach for risk assessment of nongenotoxic substances, the benchmark method, has been evaluated and applied to trichloroethene as a test case. The benchmark dose is the dose that corresponds to a specific increase in risk, normally 1 or 10%.

Aerobic biodegradation of trichloroethene without auxiliary substrates
Water Research, 2014Trichloroethene (TCE) represents a priority pollutant and is among the most frequently detected contaminants in groundwater. The current bioremediation measures have certain drawbacks like e.g. the need for auxiliary substrates. Here, the aerobic biodegradation of TCE as the sole growth substrate is demonstrated.

Trichloroethene and tetrachloroethene in ground waters of Zagreb, Croatia
Science of The Total Environment, 1997At the end of 1986 the presence of chlorinated hydrocarbons was detected in the ground water of the industrial area of Zagreb, Croatia. Concentrations of trichloroethene and tetrachloroethene were close to or exceeded maximum admissible concentrations prescribed by the Public Health Regulations for drinking water (30 micrograms/l for trichloroethene ...

Automated Analysis of Trichloroethene and Chloroform
9th ASME International Conference on Radioactive Waste Management and Environmental Remediation: Volumes 1, 2, and 3, 2003Chloroform and trichloroethene (TCE) are two organic contaminants commonly encountered in ground water. TCE, formerly a common cleaning solvent, is usually associated with contaminated aquifers. Chloroform is usually associated with the chlorination of municipal water.
