Introduction and aimsA review was undertaken on the occurrence, toxicity, and degradation of triclosan (TCS; 5-chloro-2,4-dichlorophenoxy)phenol) in the environment. TCS is a synthetic, broad-spectrum antibacterial agent incorporated in a wide variety of household and personal care products such as hand soap, toothpaste, and deodorants but also in textile fibers used in a range of other consumer products (e.g., toys, undergarments and cutting boards among other things).OccurrenceBecause of its… Expand
Occurrence, Toxicity, and Removal Methods of Triclosan: a Timely Review
Purpose of Review Triclosan (TCS) is a broad-spectrum antimicrobial agent that has been widely used in pharmaceutical and personal care products. TCS enters the environment mainly in effluent andExpand

TLDR
Emerging evidence is document here the emerging evidence--from in vitro and in vivo animal studies and environmental toxicology studies--demonstrating that TCS exerts adverse effects on different biological systems through various modes of action, speculate that T CS-induced adverse effects may be relevant to human health. Expand
In vitro effects of triclosan and methyl-triclosan on the marine gastropod Haliotis tuberculata.
TLDR
A toxic effect of TCS and MTCS on immune (hemocytes) and/or respiratory cells (gill cells) of the abalone, species living in coastal waters areas and exposed to anthropogenic pollution is revealed. Expand
Occurrence and environmental levels of triclosan and triclocarban in selected wastewater treatment plants in Gauteng Province, South Africa
Triclosan and triclocarban are industrial chemicals that are frequently added into consumer and personal care products. Information on the levels on these compounds in water systems in the AfricanExpand
Removal and metabolism of triclosan by three different microalgal species in aquatic environment.
TLDR
Hydroxylation, reductive dechlorination, or ether bond cleavage and their conjugates produced through glucosylation and/or methylation were detected in the biodegradation samples of triclosan. Expand

TLDR
This is the first scientific study to compare five different wastewater treatment processes: facultative and aerated lagoons, chemically-enhanced primary treatment, secondary activated sludge, and advanced biological nutrient removal, and determined how their removal is affected by environmental/operational factors in different WWTPs.

TLDR
The studies on the effect of TCS on soil microbiological processes showed that triclosan can disrupt the nitrogen cyclein sensitive soils at concentrations ≥5 mg/kg, and there is an urgent need to assess exposure to TCS and its effect on ecosystem health. Expand
Triclosan: environmental exposure, toxicity and mechanisms of action
TLDR
Concern has been raised over TCS's potential for endocrine disruption, as the antimicrobial has been shown to disrupt thyroid hormone homeostasis and possibly the reproductive axis, and there is strong evidence that aquatic species such as algae, invertebrates and certain types of fish are much more sensitive to TCS than mammals. Expand
Consideration of Exposure and Species Sensitivity of Triclosan in the Freshwater Environment
TLDR
State-of-the-science probabilistic exposure models, including Geography-referenced Regional Exposure Assessment Tool for European Rivers (GREAT-ER) for European surface waters and Pharmaceutical Assessment and Transport Evalutation (PhATE™) for US surface waters, have been used to predict in-stream concentrations (PECs), suggesting risks to pelagic species are low even under the highest likely exposures which would occur immediately downstream of wastewater treatment plant (WWTP) discharge points. Expand
Triclosan: occurrence and fate of a widely used biocide in the aquatic environment: field measurements in wastewater treatment plants, surface waters, and lake sediments.
TLDR
The measured vertical concentration profile of triclosan in a lake sediment core of lake Greifensee reflects its increased use over 30 years, and the measured concentrations in surface waters are in the range of the predicted no effect concentration of 50 ng/L. Expand
Effects of triclosan on various aquatic organisms.
TLDR
Triclosan exerts a marked influence on algae, which are important organisms being the first-step producers in the ecosystem; therefore, the possible destruction of the balance of the ecosystem is expected if triclosan is discharged into the environment at high levels. Expand
Environmental Exposure of Aquatic and Terrestrial Biota to Triclosan and Triclocarban.
TLDR
The synthetic biocides triclosan and triclocarban are routinely added to a wide array of antimicrobial personal care products and consumer articles and exhibit toxicity toward a number of biological receptors. Expand
Occurrence and environmental behavior of the bactericide triclosan and its methyl derivative in surface waters and in wastewater.
TLDR
Modeling the situation of lake Greifensee indicated that photodegradation can account for the elimination of triclosan from the lake and suggested a seasonal dependence of the concentrations (lower in summer, higher in winter), consistent with observed concentrations. Expand
Fate and effects of triclosan in activated sludge.
TLDR
The experiments show that TCS is extensively biodegraded and removed in activated-sludge systems and is unlikely to upset sewage treatment processes at levels expected in household and manufacturing wastewaters. Expand
Aquatic toxicity of triclosan.
TLDR
The neutral form of TCS, a chlorinated biphenyl ether used as an antimicrobial in consumer products, was determined to be associated with toxic effects and Ionization and sorption will mitigate those effects in the aquatic compartment. Expand
Effect of triclosan on microbial activity in Australian soils.
TLDR
It is demonstrated that TCS at concentrations below 10 mg/kg can disturb the nitrogen cycle in some soils, and a first-tier hazard assessment highlighted the need for further work on TCS impact on soil microorganisms. Expand
