Determining the distribution of triclosan and methyl triclosan in estuarine settings.
We have developed a method for the analysis of two sewage-derived contaminants: triclosan (TCS), an antibacterial agent, and methyl triclosan (MTCS), a TCS metabolite. For solid samples (4 g), extraction and cleanup were integrated into the same step using pressurized liquid extraction (PLE) with in-cell-clean-up (1g of florisil). The extraction was performed using dichloromethane at 100 °C, 15...
متن کاملBioconcentration of triclosan, methyl-triclosan, and triclocarban in the plants and sediments of a constructed wetland.
Constructed wetlands are a potential method for the removal of two pharmaceutical and personal care products from wastewater effluent. Triclosan (TCS; 5-chloro-2-[2,4-dichlorophenoxy]phenol) and triclocarban (TCC; 3,4,4'-trichlorocarbanillide) are antimicrobial agents added to a variety of consumer products whose accumulation patterns in constructed wetlands are poorly understood. Here, we repo...
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 کاملBiodegradation of triclosan and formation of methyl-triclosan in activated sludge under aerobic conditions.
Triclosan is an antimicrobial agent which is widely used in household and personal care products. Widespread use of this compound has led to the elevated concentrations of triclosan in wastewater, wastewater treatment plants (WWTPs) and receiving waters. Removal of triclosan and formation of triclosan-methyl was investigated in activated sludge from a standard activated sludge WWTP equipped wit...
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...
