TL;DR: The approach allowed us to define the EDBPs that it is most important to monitor in order to assess population exposure and related public health issues, and thus to improve drinking water treatment and distribution.

Journal ArticleDOI
TL;DR: Some of the wastewater and surface water samples were found to exceed the effect-based trigger values for estrogenic and glucocorticoid activity, suggesting these environmental waters may pose a potential risk to ecosystem health, while the lack of bioassay activity and low detected chemical concentrations in the drinking water samples do not suggest a risk to human endocrine health.

Journal ArticleDOI
TL;DR: Assessing whether current in vitro bioassays are suitable to detect endocrine activity in a range of water types can help provide guidance on in vitroBioassay selection and required sample enrichment for optimised detection of endocrineactivity in environmental waters.

Journal ArticleDOI
TL;DR: In this paper, the bioanalytical equivalent concentration (BEQ) approach was applied for the first time to determine the contribution of DBPs, with DBPs found to contribute between 17 and 58% of the oxidative stress response.

Journal ArticleDOI
TL;DR: The whole animal Xenopus Embryonic Thyroid Assay (XETA) detected some activity in the unspiked surface water and treated wastewater extracts, but not in unspiking drinking water, and appears to be a suitable assay to detect thyroid activity in environmental waters.

Journal ArticleDOI
TL;DR: This work demonstrates how effect data for parent compounds can be used in combination with analysis of toxicophore structures and bioconcentration potential to facilitate transformation product effect assessment and integrates existing research into a coherent model-based, risk-driven framework.
Abstract: When micropollutants degrade in the environment, they may form persistent and toxic transformation products, which should be accounted for in the environmental risk assessment of the parent compounds. Transformation products have become a topic of interest not only with regard to their formation in the environment, but also during advanced water treatment processes, where disinfection byproducts can form from benign precursors. In addition, environmental risk assessment of human and veterinary pharmaceuticals requires inclusion of human metabolites as most pharmaceuticals are not excreted into wastewater in their original form, but are extensively metabolized. All three areas have developed their independent approaches to assess the risk associated with transformation product formation including hazard identification, exposure assessment, hazard assessment including dose−response characterization, and risk characterization. This review provides an overview and defines a link among those areas, emphasizing...

TL;DR: In this article, the occurrence of Pharmaceutically active compounds (PhACs) in water and wastewater worldwide as well as their fate, focusing on the removal by conventional WTPs and the risk imposed to human health associated to the presence of PhACs in raw and drinking water.
Abstract: This paper reviews the occurrence of Pharmaceutically active compounds (PhACs) in water and wastewater worldwide as well as their fate, focusing on the removal by conventional water and wastewater treatment plants and the risk imposed to human health associated to the presence of PhACs in raw and drinking water. For this, it was assessed 23 drinking water treatment plants and 30 municipal wastewater treatment plants around the world of different capacities. Due to the high stability, intrinsic characteristics and low concentration, adsorption to the sludge and biodegradation are the most used path to remove of these compounds in wastewater treatment plants (WWTP). In water treatment plants (WTP), chlorination and application of activated granular carbon are the processes associated with the highest removal of pharmaceutical compounds, but, in general, conventional WTPs are able to reduce but not completely remove PhACs in potable water. Carbamazepine, gemfizobril and fenofibrate are found to be the PhACs that risks to human health could not be excluded. This indicates the necessity of investments in advanced techniques for the treatment of water and wastewater. The results also point to the need for more studies focusing on the determination of guideline values for drinking water of more PhACs.

TL;DR: The review examines the efficacy of process wash water disinfectants during produce processing with the aim to prevent cross-contamination of pathogens and free chlorine, chlorine dioxide, ozone, and peracetic acid were considered suitable disinfectants.
Abstract: The potential cross-contamination of pathogens between clean and contaminated produce in the washing tank is highly dependent on the water quality. Process wash water disinfectants are applied to maintain the water quality during processing. The review examines the efficacy of process wash water disinfectants during produce processing with the aim to prevent cross-contamination of pathogens. Process wash water disinfection requires short contact times so microorganisms are rapidly inactivated. Free chlorine, chlorine dioxide, ozone, and peracetic acid were considered suitable disinfectants. A disinfectant’s reactivity with the organic matter will determine the disinfectant residual, which is of paramount importance for microbial inactivation and should be monitored in situ. Furthermore, the chemical and worker safety, and the legislative framework will determine the suitability of a disinfection technique. Current research often focuses on produce decontamination and to a lesser extent on preventing cross-contamination. Further research on a sanitizer’s efficacy in the washing water is recommended at the laboratory scale, in particular with experimental designs reflecting industrial conditions. Validation on the industrial scale is warranted to better understand the overall effects of a sanitizer.
