Dioxin photoproducts of triclosan and its chlorinated derivatives in sediment cores.
Triclosan, a widely used antimicrobial, is known to undergo phototransformation in aqueous solution to form 2,8-dichlorodibenzo-p-dioxin (2,8-DCDD). Two sediment cores from a wastewater-impacted depositional zone of the Mississippi River were analyzed for triclosan by ultra performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS-Q(3)) and for a suite of polychlorinated di...
متن کاملSusceptibility of MRSA to triclosan.
Sir, Triclosan (2,4,4′-trichloro-2′-hydroxydiphenyl ether) is a broad-spectrum biocide that has been used for more than 30 years and can be found in a variety of household items, including toothpastes, cosmetics, antiseptic soaps, carpets, toys, floor cleaners, dishwashing detergents and even chopsticks.1,2 More recently it has been used in the clinical setting as part of a regimen for decoloni...
متن کاملHuman exposure to dioxin.
Because 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is the most potent chemical carcinogen evaluated by the U.S. Environmental Protection Agency (EPA), many people fear that exposure to even small amounts of TCDD could lead to serious health effects. Ambient measurements confirm that environmental TCDD contamination is widespread. The public is concerned about TCDD exposure from such diverse sou...
متن کاملRetrospective Monitoring of Triclosan and Methyl-triclosan in Fish: Results from the German Environmental Specimen Bank
ORGANOHALOGEN COMPOUNDS – Volume 66 (2004) 1489 Introduction During the last years there were several reports on the appearance of the biocides triclosan (TCS; 5chloro-2-(2,4-dichlorophenoxy)phenol; CAS No. 3380-34-5) and chlorophene (CP; 4-Chloro-2(phenylmethyl)phenol; CAS No. 120-32-1) in the environment. TCS is used in numerous personal care products like toothpaste and soaps, but also in te...
متن کاملRotating disk sorptive extraction of triclosan and methyl-triclosan from water samples.
A method of sample preparation based on use of rotating disk sorptive extraction (RDSE) has been developed for determination of triclosan (TCS) and methyl-triclosan (MTCS) in water samples. The sorptive and desorptive behavior of the analytes was studied by use of a rotating disk coated with polydimethylsiloxane (PDMS) on one of its surfaces. Chemical and extraction behavior were studied to est...
