Chlorophenols are one on the indicators for monitoring dioxins. It is reported that correlation is between the amount of chlorophenols and dioxin which are generated by garbage incineration. Moreover, if chlorine processing of the phenol in tap water is carried out, chlorophenols are generated and the nasty smell has been a problem. Furthermore, the estrogenic activity of 2,4dichlorophenol as t...

Photo catalytic degradation of chlorophenols in aqueous solution by ZnO nanoparticles under sunlight was investigated. The toxicity of chlorophenols was evaluated by agar plates technique with paper discs in the presence of Escherichia coli. The relative toxicity data of chlorophenols, before and after degradation, was used in comparing between them. The degree of toxicity was estimated by clea...

BACKGROUND Chlorophenols are environmental contaminants, which are highly toxic to living beings due to their carcinogenic, mutagenic and cytotoxic properties. Bacterial degradation has been considered a cost-effective and eco-friendly method of removing chlorophenols, compared to the traditional physical-chemical processes. RESULTS In this study, we first developed an efficient process for t...

5 Widespread use of chlorophenols in industry, agricultural and consumer products has resulted in environmental contamination. Exposure to chlorophenols can cause harmful effects in plants and animals, including humans. In this study, sediment, mussel tissues and wood samples from two local reservoirs (Kentucky Lake and Lake Barkley) were analyzed for dichlorophenol (DCP), trichlorophenol (TCP)...

The electrochemical behaviors of different chlorophenols at boron-doped diamond thin film electrode were investigated. Four chlorophenols, the 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6TCP) and pentachlorophenol (PCP), with various number of chlorine atoms in the benzene rings, were studied by using cyclic voltammetry at different scan rates over the poten...

The chlorophenols have disinfectant-like tastes, detectable in water in concentrations ranging from 0.04 parts per billion (ppb) for 2, 6-dichlorophenol to 30 ppb for pentachlorophenol (PCP). The chlorophenols are soluble in most organic solvents and are slightly soluble in water. Chlorocresols share the disinfectantchemical taste of the chlorophenols, and may have even lower taste threshold va...

The development of an immunoassay for screening contamination by chlorophenols is presented. Two haptens were synthesized and conjugated to immunizing proteins to raise rabbit polyclonal antibodies. The antibody-coated format (direct) gave better sensitivity than the conjugate-coated format (indirect) if 2,4,6-trichlorophenol is used as target analyte. The measurement range was 86.4 microg l(-1...

Enzymatic treatment of o-, m-, and p-chlorophenols and o-, m-, and p-cresols from artificial wastewater was undertaken through the enzymatic conversion into the corresponding phenoxy radicals with horseradish peroxidase (HRP) and nonenzymatic radical coupling reaction. The concentration of chlorophenols and cresols decreased sharply over the reaction time and water-insoluble oligomer precipitat...

Soil contamination due to the compounds of chlorophenols is very difficult to treat. Among the chlorophenols, pentachlorophenol (PCP) is quite persistent in the environment which causes serious pollution problem to the surface and subsurface environment (Berta et al., 2007). PCP, an important class of compounds, is used in many industrial applications, and is found in the effluent and soil asso...

Chlorophenol compounds and their derivatives are ubiquitous contaminants in the environment. These compounds are used as intermediates in manufacturing agricultural chemicals, pharmaceuticals, biocides, and dyes. Chlorophenols gets into the environment from a variety of sources such as industrial waste, pesticides, and insecticides, or by degradation of complex chlorinated hydrocarbons. Thermal...
