Characterizing the fate and transport of chemicals of emerging concern (CECs) from swine manure during waste to energy processes
… contain chemicals of emerging concern (CECs) that can threaten ecosystems and human health. For instance, estrone (E1) and 17β-estradiol (E2) can disrupt the reproductive biology of vertebrates at very low concentrations. This study investigates the effects of novel manure management …

Sorption and bioaccumulation of neutral and ionizable wastewater-derived contaminants of emerging concern: exposure of edible crops via solid and liquid effluent streams
Diverse contaminants of emerging concern (CECs) are ubiquitous in waste streams. Batch sorption tests with sludge solids from wastewater treatment systems examined sorption to the solid phase of CECs during wastewater treatment. Compounds, including neutral, acidic and basic CECs, were evaluated …

A phenomenological approach to understanding the development of athletic training preceptors
… Association. Clinical education coordinators (CECs) felt that preceptors with suitable resources and education would be able to positively affect athletic training students’ learning and educational outcomes. The educational program’s size and location influenced preceptor selection for CECs. …

Breaking the Binary: Negotiating Space and Power in Course-Embedded Consulting
<p>Course-Embedded (writing) Consultants (CECs) disrupt the common classroom power binary between the teacher and the student. Therefore, CECs must constantly negotiate authority and power in relation to their workspaces. Based on a Foucaultian analysis of power ideologies and spatial rhetoric, I …

Modeling the transport of sucralose, an anthropogenic tracer, in an effluent dependent watershed with the Soil and Water Assessment Tool during an extreme drought.
Contaminants of emerging concern (CECs) in rapidly urbanizing watersheds represent an area of increasing attention. The Soil and Water Assessment Tool (SWAT), has been used for numerous water quality and quantity assessments, but CEC studies using SWAT are limited. Because the North Bosque …

Model-based Exploration of Chemical Absorption and Metabolism Kinetics in the Human Gastrointestinal Tract
… in the physiochemical properties between CECs and pharmaceuticals. In addition, pre-absorption metabolism can potentially play an important role in the Fbio of CECs. Therefore, a physiological-based toxicokinetic (PBTK) model is built to understand the potential of chemicals to undergo …

Nanofiltration Rejection of Contaminants of Emerging Concern from Municipal Water Resource Recovery Facility Secondary Effluents for Potable Reuse Applications
… upcycling of contaminants of emerging concern (CECs) could prove harmful to human health and aquatic species if more effective and robust treatment barriers are not in place.</p> <p>There are no federal Safe Drinking Water Act (SDWA) regulations in place specifically for direct potable reuse …

Use of Biochar to Produce Reclaimed Water for Irrigation Reuse Purposes
Contaminants of emerging concern (CECs), especially, pharmaceutical and personal care products (PPCPs) are not removed well during conventional wastewater treatment and hence pose water quality risk to the environment and potentially to public health. The goal of this work was to remove CECs, with …

Desarrollo de nuevos métodos analíticos para la extracción, preconcentración y determinación de contaminantes emergentes en muestras ambientales
Los contaminantes emergentes (CECs, por sus siglas en inglés) son sustancias, productos y materiales químicos que se esparcen en el ambiente y se detectan, con frecuencia, en suelos y aguas superficiales, subterráneas y potables. Debido a la alta y continua producción de estas sustancias y su …

Evaluating non-point source microplastic pollution and its impact on biota in the Huron River
<p>Contaminants of emerging concern (CECs), like microplastics and pharmaceuticals, are a growing threat to aquatic ecosystems across the globe. Microplastics can be transported into waterways through a myriad of sources, including point sources such as wastewater treatment plants (WWTPs) and …

CHARACTERIZATION OF SEPTIC SYSTEM WASTEWATER AND MUNICIPAL SOLID WASTE LANDFILL LEACHATE
… and release of contaminants of emerging concern (CECs). The increasing volume and changing composition of waste poses new challenges for waste management and the protection of ecosystem, surface water, and groundwater resources. In the U.S., most domestic solid waste is disposed of in landfills, …
