Book Description :

Management of Emerging Public Health Issues and Risks: Multidisciplinary Approaches to the Changing Environment addresses the threats facing the rapidly changing world and provides guidance on how to manage risks to population health. Unlike conventional and recognized risks (major, industrial, and natural), emerging risks are characterized by low or non-existent scientific knowledge, high levels of uncertainty, and different levels of acceptability by the relevant authorities and exposed populations. Emerging risk must be analyzed through multiple and crossed approaches identifying the phenomenon linked to the emergence of risk but also by combining scientific, policy and social data in order to provide more enlightened decision making. Management of Emerging Public Health Issues and Risks: Multidisciplinary Approaches to the Changing Environment provides examples of transdisciplinary approaches used to characterize, analyze, and manage emerging risks. This book will be useful for public health researchers, policy makers, and students as well as those working in emergency management, risk management, security, environmental health, nanomaterials, and food science. Presents emerging risks from the technological, environmental, health, and energy sectors, as well as their social impacts Contextualizes emerging risks as new threats, existing threats in new locations, and known issues, which are newly recognized as risks due to increased scientific knowledge Includes case studies from around the world to reinforce concepts

Book Description :

"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.

Book Description :

The presence of contaminants of emerging concern (CECs) in the environment is a growing field of research for analytical environmental scientists. CECs are a class of anthropogenic pollutants not regulated by governmental agencies, and their potential deleterious environmental and human impacts are largely unknown. One of the main sources of CEC entry into the aquatic environment is wastewater treatment plant (WWTP) effluent as the treated water is often released into bodies of water, such as river and streams. Because most WWTPs were not designed to remove organic micropollutants, many CECs are poorly removed in traditional WWTPs and persist in the treated effluent waters. As a model system for study, the University Park WWTP treats the wastewater from the Penn State main campus. Following primary and secondary treatment, effluent water is then disinfected using sodium hypochlorite ("chlorine contact") and pumped for spray irrigation of over 500 acres of agricultural and forested lands called the Living Filter. The full characterization of CECs in environmental matrices requires the use of both targeted and non-targeted analysis employing a variety of advanced analytical techniques and multi-residue extraction methods. Comprehensive two-dimensional gas chromatography (GCxGC) coupled to time of flight mass spectrometry (TOFMS) is utilized for the separation and analysis of complex samples, such as wastewater. In these studies, GCxGC-TOFMS has been utilized for the non-targeted analysis of wastewater influent, effluent, and Living Filter irrigation water. Over the course of three years, these samples were investigated for CECs, revealing a new class of benzotriazole corrosion inhibitors and their transformation products. The tentatively identified chloromethyl-benzotriazole isomers were detected at higher concentrations in the effluent and irrigation water than the influent. Upon further investigation with a lab-scale synthesis, it was determined that the methyl-benzotriazoles in the influent react with sodium hypochlorite during chlorine disinfection to form previously unidentified chloromethyl-benzotriazoles. These compounds were not detected in the groundwater below the Living Filter. Traditionally, the extraction of wastewater and aqueous environmental samples is performed using liquid-liquid extraction (LLE). This method is time consuming and solvent intensive therefore a microextraction method, stir bar sorptive extraction (SBSE) was investigated. SBSE and LLE were compared for their application to multiclass organic contaminants in the University Park wastewater with GCxGC-TOFMS. LLE was found to be a better method for the quantitative analysis of a broader range of contaminants. SBSE was determined to be a more sensitive method for the non-targeted analysis of trace contaminants in effluent samples. These extraction methods were further tested and verified using wastewater from the Bellefonte, PA municipal WWTP as well as surface waters downstream of the WWTP outfall. 32 CECs, including a variety of pharmaceuticals and personal care products, were detected and tentatively identified in the samples. To further explore the fate and transport of CECs in the University Park wastewater, the soil and crops at the Living Filter were investigated. Specifically, corn roots, leaves, and grain were examined separately to determine the uptake and translocation of contaminants throughout the plant. The Living Filter samples were also compared to a corn crop control site at the agricultural research center at Rock Springs because it is not irrigated with the WWTP effluent. Target compounds detected in the soil and corn samples include herbicides, phthalates, and polycyclic aromatic hydrocarbons. Non-targeted principal component analysis of each sample type showed chemical differences between the control and Living Filter samples attributed to the treated wastewater irrigation. In addition, new chloro-dimethyl-benzotriazole compounds were tentatively identified in the wastewater as well as the Living Filter soil and corn root samples. Lastly, another class of CEC, microplastic particles (MPs), was investigated using a different set of analytical techniques. The surface characteristics and chemical composition of neat MP standards were compared to those extracted from personal care products and effluent water from the University Park WWTP. Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and Optical Profilometry were all utilized for a more comprehensive view of the MP samples. This proof-of-concept study is the first to combine the three methods for MP analysis and demonstrate that MPs extracted from personal care products and WWTP effluent differ greatly from neat microsphere standards of similar sizes. The following research presented in chapters 2-6 has been published or submitted for publication in peer reviewed journals. Chapter 2 has been published in Science of the Total Environment and chapter 6 was published in Analytical Methods. Chapter 3 has been accepted for publication in Talanta. Chapter 4 has been submitted for publication in Analytical Methods and chapter 5 has been submitted to Chemosphere. I am first author on all five of these publications.

Book Description :

"The presence of contaminants of emerging concern (CECs) in the aquatic environment and the associated proven toxic impacts have increasingly alarmed researchers. The discharge of wastewater into surface water was identified as the major source for the release of CECs into the environment. Despite the available data on the removal of CECs in wastewater treatment plants (WWTPs) in the literature, previous studies had several shortcomings, resulting in an inaccurate prediction of the CEC fate. This PhD project aimed at monitoring the fate of CECs in different treatment steps with special consideration to the hydrodynamics of the treatment units and adsorption to sludge. The project also aimed at developing and calibrating a model to predict the fate of target CECs in the most widespread secondary treatment technology: the activated sludge process. Among the various classes of CECs, this thesis focused on the widely consumed pharmaceuticals, personal care products, drugs of abuse, hormones, stimulants and artificial sweeteners based on evidences of their presence in treated wastewater implying their inefficient removal during treatment. Recently, the hydraulic characteristics of WWTPs were demonstrated to bias the calculations of CEC removal if not accounted for. To address this issue, the fractionated approach that integrates hydraulic modelling and improved sampling strategies was recently proposed. In order to verify the capability of the fractionated approach at capturing the hydraulic differences, the temperature and electric conductivity of wastewater were used as tracers to model the hydraulics of two full-scale WWTPs. Results demonstrated that a distinctive model was necessary to describe the hydraulics in each WWTP, requiring different number of days for sampling, as well as different CEC removal calculations.In order to explore the contribution of the different fate pathways to the removal of CEC during wastewater treatment, a sampling campaign was performed in a WWTP using an optimized sampling strategy based on the fractionated approach to collect and chemically analyze both wastewater and sludge samples. This allowed performing a mass balance on the incoming load of CECs, which was carried out for the first time with consideration to the hydraulic characteristics. Results indicated that for 21 out of 24 investigated CECs, degradation was the major removal process, with sorption accounting for

Book Description :

"There is a growing concern about contaminants of emerging concern (CECs) found in the environment. These CECs include pharmaceuticals, personal care products and illicit drugs that are often not easily removed using conventional treatment technologies. Aclarus has developed a low-cost, low energy ozonation system that may be applied to the treatment of wastewater. The objective of this thesis was to test the potential of the ozonation used as a disinfection technology, to remove CECs and reduce toxicity. The evaluation was performed using the Aclarus AOWWT-10 pilot ozonation unit applied to the secondary effluent at the wastewater treatment plant in Peterborough, Ontario. The unit was operated in parallel to a full-scale ultraviolet (UV) disinfection unit. A suite of illicit drugs and indicator compound were selected as a representative sample of CECs in wastewater. Wastewater samples collected prior to and after ozone or UV treatment were extracted using solid-phase extraction, and thereafter quantified for target compounds using LC/MS-MS (Orbitrap XL, Thermo) and subjected to toxicity testing. From experimental results, ozonation treatment led to disinfection levels comparable to the level obtained in the full-scale UV treatment system (>99% disinfection based on Escherichia coli counts), but yielded much higher CEC removals for a large variety of target compounds, with an average of 86% for ozonation compared to an average of 7% for UV. Statistical analysis showed that both flow rate of water through the ozonation system, as well as the level of ozone generation (i.e. ozone dose) significantly affected the removal of CECs, while the interaction between the two factors, and also system pressure had no significant effects. Based on the results of a factorial design experimental plan, optimal CEC removal can be obtained by running the Aclarus system at a flow rate of 5 gal/min, with the use of two ozone generators fed by oxygen, corresponding to an ozone dose of 5.3 mg/L. Flow rates lower than 5 gal/min were found to cause no significant additional removal of CECs.Toxicity analysis of the samples using the Microtox systems indicated that ozone-treated samples had decreased toxicity as compared to pre-treated water (secondary effluent), whilst post-UV treated water were shown to have increased toxicity after UV treatment. These results confirm our hypothesis that ozonation has additional benefits, CEC removal and decreased toxicity, even when used as a disinfection unit." --

Book Description :

"There is a continuous growth in the use of chemicals in our society, including some compounds with undefined impacts on the environment and human health, which are thus called contaminant of emerging concerns (CECs). These contaminants usually make their way into wastewater after use or disposal. The wastewater treatment plants (wwtps) are designed for the removal of conventional pollutants and therefore do not efficiently remove CECs. The CEC concentrations are generally in the low ug/L or less but they are continuously discharged in the environment and studies have shown effects at such low concentrations. These CECs include illicit drugs, pharmaceuticals, pesticides and personal care products. Ozone has been shown to remove CECs contained in wastewater, and it is now proposed as a treatment technology to meet the new regulation in Switzerland related to the removal of CECs, the first country to have regulations targeting these contaminants. However, large amounts of ozone are required to properly remove CECs, resulting in large operating and capital costs. The use of metal-based catalysts with ozone has been shown, on laboratory scale, to improve COD reduction and the removal of certain CECs. In collaboration with Air Liquide Canada, the industrial partner on this project, we used a pilot scale catalytic ozonation system to investigate this novel technology for wastewater disinfection and CEC removal. The objective of the thesis was to determine the potential of catalytic ozonation in comparison to conventional ozonation to disinfect, remove CECs and reduce toxicity of wastewater. Selected catalysts were tested in the lab and then at the pilot scale at the wwtp of the Régie d'assainissement des eaux du bassin de La Prairie. Using a 3^2 factorial design and E.coli count as an output measure, five potential catalysts were screened and the two most promising materials were determined to be Al2O3_A, a proprietary aluminum oxide based catalysts, and TAO3®. Further work was performed to determine the optimal catalyst loading and placing in the ozonation column. Results showed that increasing the catalyst loading over 80 g/L did not increase efficiency, and that TAO3 appeared to work best when placed in the middle of the column, while Al2O3_A was more efficient when placed at the bottom. Statistical analysis showed that both catalysts significantly reduced the amount of ozone required to reach a target disinfection of 2 MPN/mL of fecal coliforms. A reduction of the ozone requirement of 2.5 mgO3/Lww was obtained for both catalysts when compared to conventional ozonation, which would result in tons of ozone saved daily on a full scale wwtp, hence reducing the capital and operating costs. Using optimal conditions for each catalyst, triplicate experiment were then performed with a full analysis including disinfection, CEC removal, formaldehyde formation, acute toxicity, estrogenic activity removal, COD and TOC removal. Results for Al2O3_A confirmed the improvement in disinfection, a decreased requirement of 2.5 mgO3/Lww over ozonation, and indicated additional removal > 15% increased for 7 out of the 10 CECs detected. No increase in acute toxicity was detected, no changes were observed in the amount of formaldehyde produced, the removal of COD, TOC and residual toxicity. Catalytic ozonation was shown to be a promising technology to help wwtp managers meet more stringent regulations. Economical analysis, optimization and scale-up are now required to continue the investigation of this novel technology. " --

Book Description :

"The increasingly more stringent regulations related to wastewater quality and the inability of conventional wastewater treatment to adequately eliminate contaminants of emerging concern (CECs) make it essential to develop novel treatment approaches to upgrade existing treatment train. Catalytic ozonation is one of the newest advanced oxidation processes (AOPs) investigated as a strategy to improve the quality of wastewater prior to discharge in the environment. The present Ph.D. thesis focused on expending the knowledge about catalytic ozonation and identify novel materials as efficient catalysts for CECs removal and wastewater disinfection. The results of this research are presented in two manuscripts. The first manuscript reports on the screening of the potential catalysts, on the apparent reaction kinetics, and on the reusability of the most promising catalysts. The screening was conducted in a semi-batch reactor in MilliQ water (MQW) and synthetic wastewater. TiO2/Al2O3, AL-1010S (Al2O3-based catalyst), and Polonite® were shown to enhance the efficiency of catalytic treatment for the CECs removal and disinfection of E. coli. The apparent kinetic reaction between oxidative species (ozone and hydroxyl radicals) and atrazine (ATZ) was studied in a batch reactor in MQW with the addition of scavengers. The reusability experiments demonstrated that TiO2/Al2O3 and AL-1010S maintained their efficiency over four consecutive days, with removal of ATZ at the level of more than 90% and disinfection efficiency exceeding the one obtained using non-catalytic ozonation by more than 1.5 MPN Log units. Polonite® provided the least stable efficiency as a function of time but provided significant increase in disinfection. The second manuscript reports on the effect of wastewater characteristics (chemical oxygen demand (COD) and nitrite (NO2) concentration) and operating conditions (ozone to catalysts ratio, ozone concentration, and hydraulic retention time (HRT)) on process efficiency using the two most promising materials identified, Polonite® and AL-1010S. The optimal parameters for disinfection and ATZ removal were defined to be 8 g-O3 nm3 of ozone gas concentration, 10 minutes of HRT and a ratio of 0.11 of ozone gas concentration to catalyst loading. Both NO2 and COD concentrations greatly impacted the efficiency of treatment but the use of AL-1010S or Polonite® rendered the process less sensitive to variations of these wastewater characteristics. The benefits of catalytic ozonation using AL-1010S or Polonite® were verified for the disinfection of effluent wastewaters collected from two municipal wastewater treatment plants but analytical challenges limited the information available to conclude on the potential for improved CEC removal." --

Book Description :

This report follows key policy questions that provide an insight into the relationship between agriculture and environment in the accession countries. It covers agricultural characteristics, trends and changes, effect on EU enlargement and key agri-environmental policy options of the 13 accession countries. It finds that the process of modernisation and intensification of agriculture has been disrupted by political changes. Agriculture is currently characterised by low inputs and productivity as a high associated biodiversity. Accession to the EU will make more resources available for agri-environment schemes and other rural development measures. These are important for reducing the environmental impact of the current trends. National level implementation and capacity building are key factors for making EU enlargement a success in this regard
