Contaminants of Emerging Concern in Water and Wastewater: Advanced Treatment Processes presents the state-of-the-art in the design and use of adsorbents, membranes, and UV/oxidation processes, along with the challenges that will need to be addressed to close the gap between development and implementation in water/wastewater treatment applications. Chapters cover adsorbent and membrane design and performance, direct comparison of performance data between new (inorganic and metal organic nanoporous materials) and classic adsorbents and membranes, a list of advantages, disadvantages, and challenges related to performance limitations, regenerability, and upscaling. In addition, users will find sections on the identification of potential site and off-site applications that are listed according to adsorbent and membrane types, transformation of CECs in low- and/or medium-pressure UV irradiation processes used for disinfection, the oxidation of CECs by chlorine and ozone, and a comparison of advanced oxidation processes for the treatment of a variety of CECs in water and wastewater. Addresses the advantages/disadvantages of select technologies, including energy resource needs and waste management issues of reverse osmosis, amongst other issues Presents information on the advancements of technology within the realm of Engineered Treatments of CECs Focuses on the inherent science and technology of advanced treatment processes

"Conventional wastewater treatment plants were not designed to remove contaminants of emerging concern (CECs), and hence these chemicals have been shown to contribute to contamination into the environment, where CECs ultimately exist in the parts per trillion to parts per million concentration range. CECs have been shown to induce toxicity in aquatic life which has led to concern from researchers, governments and more recently the general public. Consequently, there is a pressing need for technologies to remove CECs and their associated toxicity, and for wastewater quality measurement methods to monitor these contaminants. Treatment of wastewater by ozone has been shown to reduce or remove many CECs; while many studies have demonstrated a decrease in the toxicity associated with their removal, some have reported a toxicity increase. This highlights the need to monitor the success of wastewater treatment by ozone using bioassays. The LuminoTox bioassay, which measures photosynthetic inhibition, was proposed as a tool for this application. While the LuminoTox has been used for different types of water analysis, there is limited research on its applicability for wastewater monitoring, and in particular, in municipal secondary effluents (SEs). In this PhD project, the LuminoTox was explored as a tool for the detection of CECs in wastewater and for monitoring the removal of CEC-associated toxicity during treatment by ozone. Two current LuminoTox biosensors were explored: Photosynthetic Enzyme Complexes (PECs), and Stabilized Aqueous Photosynthetic Systems I (SAPS I), as well as a new biosensor, SAPS II. In this PhD, the LuminoTox proved to be a good monitoring tool for toxicity of SEs and demonstrated the ability to detect and distinguish changes in CECs in wastewater mixtures. Furthermore, it proved to be excellent at monitoring wastewater during treatment by ozone. The LuminoTox, however, demonstrated limited CEC sensitivity at environmentally relevant concentrations. The LuminoTox pre-concentration method increased the sensitivity of the LuminoTox into the range applicable to native CECs in SE but further development of the sample preparation method is required prior to implementing the technology for wastewater monitoring.

An excellent, concise, and interdisciplinary overview of different classes of emerging pollutants arising, for example, from pharmaceuticals, pesticides, personal care products, and industrial chemicals and their impact on water, soil, and air. Following an introduction to chemical pollutants, with special attention focused on organic compounds and their properties, the book goes on to describe major emerging pollutants grouped according to their applications in different sectors of industrial or economic activity. For each type of compound, the chemical structure, main properties, and source are presented, along with their fate in the environment as pollutants, the latest analytical methods for detection, possible health or ecology consequences, as well as current regulatory laws. New developments, such as nanotechnology as a pollution source, are also included. The book closes with a chapter devoted to conclusions and future perspectives.

Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.
