TL;DR: This study investigated the applicability of different techniques for fluorescence excitation/emission matrices data interpretations, including peak-picking method, fluorescence regional integration and PARAFAC modelling, to act as surrogates in predicting emerging trace organic compounds removal during conventional wastewater treatments.
Journal ArticleDOI
Predicting trace organic compound breakthrough in granular activated carbon using fluorescence and UV absorbance as surrogates.
TL;DR: Surrogate predictions using UV254 and TF provide valuable tools for rapid or on-line monitoring of GAC performance and can result in cost savings by extended GAC run times as compared to using DOC breakthrough to trigger regeneration or replacement.
Journal ArticleDOI
Triclosan in water, implications for human and environmental health
TL;DR: Results from epidemiological studies on the effect of TCS on human health have implicated the compound as responsible for certain allergies and reproductive defects, which raises toxicity concern for humans as carcinogenic metabolites such as chlorophenols may be generated in the presence of the residual chlorine.
Journal ArticleDOI
Occurrence and fate of emerging trace organic chemicals in wastewater plants in Chennai, India.
TL;DR: The effluent composition of the 22 TOrCs were similar within the three WWTPs but quite different to those seen in the US, indicating the importance of region-specific monitoring.

Pharmaceuticals, hormones, and other organic wastewater contaminants in U.S. streams, 1999-2000: a national reconnaissance.
Dana W. Kolpin,Edward T. Furlong,Michael T. Meyer,E. Michael Thurman,Steven D. Zaugg,Larry B. Barber,Herbert T. Buxton +6 more
TL;DR: The U.S. Geological Survey used five newly developed analytical methods to measure concentrations of 95 organic wastewater contaminants (OWCs) in water samples from a network of 139 streams across 30 states during 1999 and 2000 as mentioned in this paper.

TL;DR: Atenolol, atrazine, DEET, estrone, meprobamate, and trimethoprim can serve as indicator compounds representing potential contamination from other pharmaceuticals and EDCs and can gauge the efficacy of treatment processes.

Fate of endocrine-disruptor, pharmaceutical, and personal care product chemicals during simulated drinking water treatment processes.
TL;DR: Conventional treatment would have low removal of many EDC/PPCPs, while addition of PAC and/or ozone could substantially improve their removals, and existing strategies that predict relative removal of herbicides, pesticides, and other organic pollutants can be directly applied.

An extensive new literature concerning low-dose effects of bisphenol A shows the need for a new risk assessment.
TL;DR: It is proposed that a new risk assessment for BPA is needed based on the extensive new literature reporting adverse effects in animals at doses below the current reference dose, and the high rate of leaching of BPA from food and beverage containers, leading to widespread human exposure.
