Chlorophenol Exposure in Sawmills
American Industrial Hygiene Association Journal, 1985Personnel exposures to chlorophenols were measured in ten Finnish sawmills where a chlorophenolate salt formulation was used for the blue stain control of sawed wood. The concentrations of chlorophenols in the air were usually well below the occupational limit value of 0.5 mg/m3. However, high concentrations (above 10 mg/m3) were measured inside heated

Letters in Applied Microbiology, 1995
A Gram-negative aerobic bacterium capable of using 2-chlorophenol (2-CP), 3-chlorophenol (3-CP) and 4-chlorophenol (4-CP) as sole carbon sources was isolated and characterized. The bacterium, designated LD1, was identified to be a Pseudomonas pickettii strain. LD1 was able to totally degrade and dechlorinate 2-CP (initial concentration: 1.51 mmol l-1),

Genetic Activity of Chlorophenols and Chlorophenol Impurities
1978Studies were made of the genetic activity of 2,4,6-trichlorophenol, pentachlorophenol, and their impurities: 2,3,7,8-tetrachlorodibenzofuran 2,4,4′,6-tetrachlorodiphenyl ether 2,4,4′, 5-tetrachlorodiphenyl ether 4,5,6-trichloro-2-(2,4-dichlorophenoxy)phenol, (Cl5-predioxin) 4-chloro-2-(2,4-dichlorophenoxy)phenol, (Cl3 ...

The transformation of chlorophenols by lactoperoxidase
Biochimica et Biophysica Acta (BBA) - General Subjects, 1985The lactoperoxidase-catalyzed transformations of penta-,2,3,4,6-tetra-, 2,4,6-tri-, 2,4-di- and 4-monochlorophenol were followed spectrophotometrically. Apparent stoichiometries of chlorophenol:H2O2 ranged from 1:1 for the tri- and tetrachlorophenol at pH7 to 5:2 for pentachlorophenol at pH 4.

Enzymatically mediated incorporation of 2-chlorophenol and 4-chlorophenol into humic acids
Chemosphere, 1994Abstract A possible route to chlorinated humic substances in the environment, is an indirect chlorination of humic material by enzymatically mediated incorporation of low molecular weight organo-chlorine compounds into the humic skeleton. The enzymatically mediated incorporation of 2-chlorophenol and 4-chlorophenol into humic acids by Horseradish ...

Induction of prophage lambda by chlorophenols
Environmental and Molecular Mutagenesis, 1990AbstractChlorinated phenols, which are used primarily as wood preservatives and fungicides, are present in most air, water, and soil samples in industrialized areas as well as in the urine of most people. We have examined the ability of phenol and the 19 isomers of chlorophenol to induce DNA damage using the Microscreen prophage‐induction assay in ...

Marine Bacteria Tolerant to Chlorophenols
Bulletin of Environmental Contamination and Toxicology, 1999The cellulose industry produce chlorophenols as a result of the use of chlorine during pulp cellulose bleaching, and are discharged into natural waters by their effluents. The pollution of coastal sea waters by chlorophenols and several other organic compounds could modify the biota of this environment because the compounds have high toxicity, are ...

Lethal Body Residue of Chlorophenols and Mixtures of Chlorophenols in Benthic Organisms
Archives of Environmental Contamination and Toxicology, 2001The lethal body residue (LBR) of a few chlorophenol congeners were measured in the oligochaete worm Lumbriculus variegatus, and the LBR of pentachlorophenol was measured also in a midge, Chironomus riparius larvae. LBR is defined as the concentration of the compound in the organism, on molar basis, to cause death, and the LBR(50) is defined as the ...

Wet peroxide oxidation of chlorophenols
Water Research, 2005This study evaluates the application of Wet Peroxide Oxidation (WPO) for the treatment of solutions containing 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP). These compounds are of special interest due to their high toxicity and low biodegradability.
