Nonylphenyl (NP) and NP ethoxylates (NPEs) are a group of organic chemicals that are widely used as surfactants, emulsifiers, wetting agents, and dispersants in a wide variety of industrial processes & commercial products. This document provides the rationale for development of Canadian environmental quality guidelines for NP & NPEs. It contains technical background information on the chemical & physical properties of NP & NPEs and a review of their sources & emissions in Canada, the distribution & behaviour of these chemicals in the environment, their toxicological effects on aquatic & terrestrial species, and NP/NPE guidelines developed in other jurisdictions. The information is then used to derive water, sediment, & soil quality guidelines for NP/NPEs to protect ecological receptors in each of these environmental compartments. The final sections suggest areas for future research & provide guidance on implementation of the guidelines.

The report outlines the technical aspects of the various approaches and methodologies available with respect to the assessment of risks from combined exposures to multiple chemicals. The document draws from approaches applied and experience gained in the regulatory context and will therefore be most relevant to the regulatory authorities addressing chemicals, the regulated community and other interested stakeholders.

Over the last few years there has been a growing concern over the increasing concentration of micropollutants originating from a great variety of sources including pharmaceutical, chemical engineering and personal care product industries in rivers, lakes, soil and groundwater. As most of the micropollutants are polar and persistent compounds, they are only partially or not at all removed from wastewater and thus can enter the environment posing a great risk to the biota. It is hypothesized that wastewater is one of the most important point sources for micropollutants. Treatment of Micropollutants in Water and Wastewater gives a comprehensive overview of modern analytical methods and will summarize novel single and hybrid methods to remove continuously emerging contaminants - micropollutants from the aqueous phase. New trends (e.g. sensor technology, nanotechnology and hybrid treatment technologies) are described in detail. The book is very timely because the new techniques are still in the development phase and have to be realized not only in the laboratory but also on a larger scale. The content of the book is divided into chapters that present current descriptive and analytical methods that are available to detect and measure micropollutants together with detailed information on various chemical, biological and physicochemical methods that have evolved over the last few decades. Treatment of Micropollutants in Water and Wastewater will also enable readers to make well informed choices through providing an understanding of why and how micropollutants must be removed from water sources, and what are the most appropriate and available techniques for providing a cost and technologically effective and sustainable solutions for reaching the goal of micropollutant-free water and wastewater. The book will be suitable for water and wastewater professionals as well for students and researchers in civil engineering, environmental engineering and process engineering fields.

In order to analyse the challenges posed by the quest for sustainability, Green Technologies for Wastewater treatment: Energy Recovery and Emerging Compounds Removal evaluates water management together with energy use. The strong effects that the release of emerging pollutants such as endocrine disruptors (EDCs), pharmaceuticals and personal care products (PPCPs) have in wastewater reuse applications are examined, as well as the need to optimize the energy consumption in wastewater treatment. More specifically, this volume focuses on: - Presenting the advantages linked to the application of chemically assisted primary sedimentation (CAPS) that enables energy optimization of wastewater treatment plants and points to the possibility of wastewater as a possible resource; - Discussing the analytical problems related to the analytical detection of emerging pollutants and of their transformation products; - Comparing the efficiency of MBR plants for removing trace pollutants with conventional systems; - Evaluating the application of Wet Oxidation (WO) for the treatment of aqueous effluents to remove trace pollutants; - Reviewing the application of Photo-Fenton process and complementary treatment systems (H2O2/UV-C and Fenton’s reagent) for the degradation of two industrial pollutant categories with significant endocrine disrupting properties: alkyl phenols (nonyl and octyl phenols) and bisphenol A. Green Technologies for Wastewater treatment: Energy Recovery and Emerging Compounds Removal will be of great interest to students, technicians, and academics alike who are interested in evaluating and selecting the technologies that lead to better and more sustainable treatment of these huge classes of pollutants.
