Abstract:

In recent decades, previously unobserved trace compounds have become more widely detected in wastewater treatment effluents and freshwater ecosystems. Emanating from various sources and presenting potential human health and ecological risks at much lesser concentrations than traditional contaminants, detection of “emerging contaminants” has increased with improvements in analytical techniques. The behavior of emerging contaminants in wetlands is a topic of increasing interest, as natural wetlands are known to transform and sequester pollutants and constructed or treatment wetlands are widely utilized to address elevated concentrations of constituents of concern. Both natural and constructed wetlands are complex biogeochemical systems with interrelated abiotic and biotic mechanisms leading to the removal of emerging contaminants. A literature review was performed to assess the current state of knowledge of various wetland mechanisms involved in removing these contaminants from surface waters and effluents. The primary mechanisms discussed in the literature are sorption, photodegradation, microbial biodegradation and phytoremediation. The most influential mechanisms are dependent on the properties of the contaminants and wetland systems studied. Common trends exist for different constructed wetland designs to leverage various mechanisms based on hydrology, substrate and vegetation plantings. Much remains to be understood about the various processes occurring in wetlands as they relate to emerging contaminant removal. Improving the understanding of the potential role of wetland mechanisms can help manage this environmental challenge more effectively.

Abstract:

Abstract Rapid increase in population and emergence of many industries led to the emergence of contaminants from various sources such as domestic, industrial and agricultural activities etc. These contaminants reach the groundwater, surface water, municipal wastewater and food sources from agricultural fields. These pollutants contaminate the soil and in long term contaminate the groundwater sources due to transportation phenomena. Once the soil and groundwater are contaminated, the environment becomes a threat to the living beings. The objective of this article is to give an overview of the various types of contaminants, their emerging sources, their effect on the environment and suitable remediation techniques with emphasis on bioremediation techniques such as phytoremediation, phycoremediation, mycoremediation, bioventing, bioleaching, landfarming, bioreactor, composting, bioaugmentation, rhizofiltration, and biostimulation for treatment of these contaminants.This chapter mainly focusses on the fate of the contaminants emerging from various activities, their effects on the environment, remediation techniques and in specific the environmental friendly techniques to remediate the contaminated soil and water.

Abstract:

Emerging contaminants have been increasingly recognized as critical determinants in global public health outcomes. However, the intricate relationship between these contaminants and glucose metabolism remains to be fully elucidated. The paucity of comprehensive clinical data, coupled with the need for in-depth mechanistic investigations, underscores the urgency to decipher the precise molecular and cellular pathways through which these contaminants potentially mediate the initiation and progression of diabetes mellitus. A profound understanding of the epidemiological impact of these emerging contaminants, as well as the elucidation of the underlying mechanistic pathways, is indispensable for the formulation of evidence-based policy and preventive interventions. This review systematically aggregates contemporary findings from epidemiological investigations and delves into the mechanistic correlates that tether exposure to emerging contaminants, including endocrine disruptors, perfluorinated compounds, microplastics, and antibiotics, to glycemic dysregulation. A nuanced exploration is undertaken focusing on potential dietary sources and the consequential role of the gut microbiome in their toxic effects. This review endeavors to provide a foundational reference for future investigations into the complex interplay between emerging contaminants and diabetes mellitus.

Abstract:

Термин «emerging contaminants» получил широкое распространение в современной научно-технической литературе, посвященной проблематике загрязнения окружающей среды. Между тем примеры употребления вариантов перевода данного термина в русскоязычной профильной литературе свидетельствуют об отсутствии адекватного понимания значения данного термина. В англоязычной научно-технической литературе к «emerging contaminants» в настоящее время относят вещества и материалы природного, промышленного или искусственного происхождения, которые были обнаружены или предположительно присутствуют в различных средах, и токсичность или стабильность которых могут существенно изменить метаболизм живых существ. Такие вещества классифицируют как «emerging contaminants» до тех пор, пока в научной литературе существует недостаток информации или плохо документированы вопросы о связанных с ними потенциальных проблемах. В целом «emerging contaminants» демонстрируют определенный потенциал для создания рисков для здоровья человека или окружающей среды, но не подпадают пока под регулирующие критерии или нормы для защиты здоровья человека или окружающей среды. Общим для них является отсутствие соответствующих данных о месте в окружающей среде и потенциальной токсичности, что не позволяет правильно оценить связанные с ними риски. Уже регулируемые, предположительно хорошо известные загрязняющие вещества могут вновь обрести статус «emerging contaminants» по мере поступления новой научной информации, что послужит основанием для регулирующих органов пересмотреть свои нормы и рекомендации. The term «emerging contaminants» has been widely used in modern scientific and technical literature on the problem of environmental pollution. Meanwhile, the examples of using translation versions of this term in the Russian-language relevant literature indicate the lack of an adequate understanding of the meaning of this term. In the English-language scientific and technical literature «emerging contaminants» currently refer to the substances and materials of natural, industrial or artificial origin found or presumably present in various environments; and their toxicity or stability can significantly change the metabolism of living beings. These substances have been classified as «emerging contaminants» while there is a lack of information in the scientific literature, or questions about their potential problems have been poorly documented. In general, «emerging contaminants» show certain potential to create risks to the human health or environment; however, they have not been subject to regulatory criteria or standards to protect human health or the environment, so far. What they have in common is the lack of relevant data on the environmental role and potential toxicity, which makes assessing correctly the risks associated with them impossible. Already regulated, presumably well-known pollutants may revert to the status of «emerging contaminants» as and when new scientific information becomes available, prompting regulators to revise regulations and recommendations.

Abstract:

Emerging contaminants are substances found in the environment whose concentrations vary from µg to ng L-1 and whose presence in wastewater has gained popularity in the scientific community due to the potential impacts these compounds can cause to the environment. This designation concerns the lack of legislation to regulate their discharge or even to monitor these compounds. Moreover, emerging contaminants are capable of causing harmful effects to nontarget organisms and therefore affect the ecosystem balance. There are several compounds classified as emerging contaminants such as pharmaceuticals, illicit drugs, hormones, pesticides, among others. And among them, caffeine is considered an emerging contaminant and can be highlighted due its presence in medicines, beverages, foodstuff and several other products. In addition, it is a compound used worldwide recognized as a marker of anthropogenic activity. In this review, we present a discussion about emerging contaminants, focusing on caffeine, regulatory aspects that involve the theme, as well as effects on organisms, removal technologies and techniques for analyzing these compounds in environmental matrices.

Abstract:

There are potentially many thousands of municipally derived contaminants of emerging concern (CECs) present in discharged wastewaters that may cause adverse effects in receiving aquatic environments. Wastewater authorities, therefore, may face the momentous task of investigating these compounds with little or no prior CEC data for their sewage treatment plants (STPs). Such is the case for the Cleveland Bay Sewage Treatment Plant (CBSTP). To evaluate the potential environmental risk posed by municipal CECs, it is first necessary to understand which CECs are present in discharging wastewater, how they will be sampled and quantified, and which CECs are the most concerning regarding ecological risk. A Sampling Analysis and Quality Plan (SAQP) is a valuable tool that can be used to critically review and detail the strategy that will be adopted to achieve these outcomes. As such, this paper describes the development of a SAQP for screening wastewaters released from the CBSTP into Cleveland Bay as part of a preliminary CEC assessment. This paper describes the qualitative decision-making process employed to shortlist CECs into those perceived to pose the greatest ecological risk. In addition, the rationale and methods adopted to determine sampling locations and frequency are described.

Abstract:

Contaminants of emergent concern (CECs) in aquatic ecosystems entail a potential risk for the environment, due to their persistent behavior and adverse effect on living organisms during a long-term exposition, even at residual concentrations. Conventional Wastewater Treatment Plants (WWTPs) are not designed to eliminate CECs properly because the treatment technologies are not enough to remove these contaminants, which generates environmental and technological challenges. In this review, the sources of CEC contaminants to aquatic environments have been discussed in detail. Understanding the occurrences and pathways of CECs, their adverse effects on the environment, and removal techniques is a valuable key for the proper maintenance of global ecological health. This scenario was more explored through the harmful impacts of CECs on the environment, including their toxic effects and permissible limits. This review gathers information about CECs occurrences from a global perspective compiling information about their ecotoxicological effects, conventional and advanced treatment methods towards their mitigation. Advanced hybrid treatment techniques such as membrane bioreactor with ozonation, reverse osmosis, and ultrafiltration have shown to be a promising alternative for CECs removal. New advanced oxidation processes with assisted and non-assisted UVC/H2O2 systems with TiO2 photocatalysis were also demonstrated as a good approach to be implemented in the CECs mitigation strategies.

Abstract:

Abstract A new concern about surface water quality is the occurrence of emerging contaminants that have being recognized as a new class of water contaminants such as antibiotics, hormones, pesticides, personal care products and pharmaceutical products. The occurrence of these contaminants in the aquatic environment and especially in surface water is a serious concern because this is usually the source of water for drinking water treatment plants (DWTP). This review provides a summary of the occurrence and the analytical methodology (extraction process, chromatography analysis, detection systems and ionization source) of emerging contaminant analysis in surface waters including rivers, lakes, creeks and wetlands for their analysis.

Abstract:

The bioaccumulation of organic contaminants in the Lake Erie food web is reviewed in context of the numerous changes experienced by the system. In the late 1960s, internal lake processes, related to the eutrophic status of the lake, minimized contaminant bioaccumulation despite high contaminant loadings. From the 1970s to 1980s contaminant concentrations decreased at different rates in many species of different trophic levels, coincident with decreased loadings to the lake. Since the early 1980s contaminant concentrations in biota have not changed consistently. Several factors have been proposed to account for these patterns, including reduced nutrient loadings and productivity, and the invasion of several exotic species such as zebra mussels. These factors have altered the food web structure and the internal distribution of contaminants in the lake. Emerging and continuing issues, such as climate change, invasions of additional exotic species, new chemical contaminants of concern, and algal toxins will likely impact contaminant dynamics in the future.Key words: Lake Erie, bioaccumulative contaminants, food web.

Abstract:

The presence of emerging contaminants in water resources has been a global concern due to their environmental impact and effects on human and animal health. These compounds include pharmaceuticals and personal care products, pesticides, fire retardants, hormones, and plasticizers, among others. These contaminants are not completely removed during water and wastewater conventional treatment. Thus, alternative processes are necessary to face this issue. In this context, nanotechnology represents a promising strategy for the remediation of emerging contaminants. Nanostructured materials have highlighted properties, such as adsorption capacity and porosity, chemical stability, reactivity, mobility, and antimicrobial activity. The diversity of nanomaterials and the possibility of combining them contribute to their application in contaminant mitigation. Furthermore, they can be used in different removal techniques such as adsorption, and membrane filtration. Thus, this review article provides an overview and advances in the production and application of nanofiltration membranes and adsorbent nanomaterials for the treatment of effluents containing emerging pollutants.

Abstract:

The pervasive presence of emerging contaminants in food and the environment poses a grave threat to human health and ecological stability. Addressing this challenge necessitates a comprehensive approach that integrates physiochemical characterization techniques into toxicological screening protocols. This paper provides an extensive review of the methodologies and advancements in the amalgamation of various physiochemical characterization techniques, including chromatography, spectroscopy, and mass spectrometry, in toxicological screening for emerging contaminants. By synergistically employing these techniques, the identification, quantification, and toxicity assessment of contaminants are significantly enhanced, facilitating a thorough understanding of their implications for human health and environmental integrity. Through case studies and empirical evidence, this paper underscores the pivotal role of integrated physiochemical characterization techniques in ensuring the safety of food and the environment. By integrating these physiochemical characterization techniques into toxicological screening workflows, researchers can elucidate the presence of emerging contaminants, assess their bioavailability and bioaccumulation potential, and evaluate their toxicological profiles. Furthermore, the synergistic application of these techniques facilitates the identification of transformation products and metabolites, enhancing our understanding of contaminant fate and behavior in environmental matrices and food systems DOI: https://doi.org/10.52783/tjjpt.v45.i02.6483

Abstract:

The anti-inflammatory drug ibuprofen is considered to be an emerging contaminant because of its presence in different environments (from water bodies to soils) at concentrations with adverse effects on aquatic organisms due to cytotoxic and genotoxic damage, high oxidative cell stress, and detrimental effects on growth, reproduction, and behavior. Because of its high human consumption rate and low environmental degradation rate, ibuprofen represents an emerging environmental problem. Ibuprofen enters the environment from different sources and accumulates in natural environmental matrices. The problem of drugs, particularly ibuprofen, as contaminants is complicated because few strategies consider them or apply successful technologies to remove them in a controlled and efficient manner. In several countries, ibuprofen’s entry into the environment is an unattended contamination problem. It is a concern for our environmental health system that requires more attention. Due to its physicochemical characteristics, ibuprofen degradation is difficult in the environment or by microorganisms. There are experimental studies that are currently focused on the problem of drugs as potential environmental contaminants. However, these studies are insufficient to address this ecological issue worldwide. This review focuses on deepening and updating the information concerning ibuprofen as a potential emerging environmental contaminant and the potential for using bacteria for its biodegradation as an alternative technology.

Abstract:

Abstract ‘Emerging contaminants’ are newly introduced into the environment through release into surface waters from wastewater treatment effluent, manufacturing, and agricultural use. How emerging contaminants move through water systems is unclear. Since the decay rates of emerging contaminants in piping systems have not been determined, this study determines the importance of decay rate on concentration throughout a distribution system and also determines how the system layout effects concentration. Systems were modeled to determine the time to peak contamination for a clean system becoming contaminated, as well as a contaminated system being cleaned of contamination. It was found that only emerging contaminants with second-order decay at the highest rate observed did not build up to high concentrations. The position of storage tanks in the distribution system affected the rate at which contaminants cleared the system, and systems with a branched layout could be cleared of contamination faster than systems containing loops.

Abstract:

Emerging contaminants are being detected at a high frequency, posing significant environmental and human health challenges. This study aimed to investigate the potential of using commercial granular activated carbon for adsorbing nine aqueous emerging contaminants (carbamazepine, phenacetin, pentoxifylline, norfloxacin, iprobenfos, isoprothiolane, metolachlor, tebuconazole, and hexaconazole). The adsorption study involved employing kinetic and isotherm models, using various concentrations of emerging contaminants and sorbents in a batch system. Additionally, the study explored the correlation between the characteristics of emerging contaminants and their adsorption values, which displayed a relatively linear relationship. While some previous papers have evaluated the performance of one or two substances, there is a lack of research on the adsorption mechanisms of all nine aqueous emerging contaminants. Therefore, the findings from this study on the adsorption potential of granular activated carbon can serve as a valuable foundation for further investigations into its effectiveness in adsorbing emerging contaminants.

Abstract:

For survival and quality of human life, the search for better ways to ensure food safety is constant. However, food contaminants still threaten human health throughout the food chain. In particular, food systems are often polluted with multiple contaminants simultaneously, which can cause synergistic effects and greatly increase food toxicity. Therefore, the establishment of multiple food contaminant detection methods is significant in food safety control. The surface-enhanced Raman scattering (SERS) technique has emerged as a potent candidate for the detection of multicomponents simultaneously. The current review focuses on the SERS-based strategies in multicomponent detection, including the combination of chromatography methods, chemometrics, and microfluidic engineering with the SERS technique. Furthermore, recent applications of SERS in the detection of multiple foodborne bacteria, pesticides, veterinary drugs, food adulterants, mycotoxins and polycyclic aromatic hydrocarbons are summarized. Finally, challenges and future prospects for the SERS-based detection of multiple food contaminants are discussed to provide research orientation for further.

Abstract:

Industrial development has made new products available to people to make their lives easier. Items such as food, cleaning, personal care and health products, among others, are processed, sold and consumed daily by all age groups. These products include in their formulation inorganic and organic chemicals with the purpose of improving or increasing some of their properties, making them more attractive to the consumer. These substances are strictly controlled during production so that the final product may be safely consumed. In most cases, the constituents of commercial products end up in wastewater, where they are not controlled. These uncontrolled pollutants of differing chemical natures are known as “Emerging Contaminants” (ECs). Research worldwide has found ECs in various environmental matrices, especially water. To understand this problem, four fundamental aspects must be addressed: 1) the analytical methods for its determination; 2) the occurrence in environmental matrices; 3) the treatments for the removal of ECs in wastewater and drinking water plants; and 4) the risks to health and the environment. This document reviews these four aspects with regard to 14 ECs commonly found in the studies around the world and addresses the state of these ECs in trans-American waters.

Abstract:

Numerous studies on environmental remediation have been focused on water pollution by pharmaceuticals. Diclofenac (DCF) is regarded as an anti-inflammatory drug which is used globally. For more than 10 years now, intensive studies have shown the distribution of diclofenac in various environmental media at different concentrations worldwide. In this case, diclofenac behaviour in different environmental matrices especially soil and water were addressed, giving credence to modem remediation techniques. Toxicity issues as it concerns diclofenac in both soil and water as well as exposure to diclofenac metabolites via consumption and abiotic degradation route has also been discussed. Possible Mechanisms of dikclofenac interactions with other contaminants, ranging from interactions with metals, other inorganic and organic matter, and with other emerging contaminants and diclofenac metabolites have been duly discussed.

Abstract:

Processing contaminants are chemical substances that have not been intentionally added to edible oils or food. These substances may be present in edible oils and food as a result of the various stages of its production, processing, transport or environmental contamination and may pose a risk to animal and human health. Processing methods include fermentation, smoking, drying, refining and high-temperature cooking. Many foods must be cooked to actually be edible and digestible. It also makes them tastier. However, baking, frying, grilling or barbecuing, either at home or in manufacturing, can have undesired consequences. Besides the loss of some nutrients like vitamins, potentially harmful by-products can develop too. 3-Monochloropropanediol (3-MCPD) is an organic chemical compound, one of the heat- and process-induced food contaminants, belonging to a group called chloropropanols and is considered as the most toxic processing contaminant emerging during thermal treatments in refining of edible oils. The aim of this review was to provide an overview of current knowledge regarding 3-MCPD in edible oils for further research, in order to reduce its contents in consumed foodstuffs.

Abstract:

AbstractThe presence of various types of contaminants such as heavy metals, emerging organic contaminants, pesticides, organic waste, organic dyes, radionuclide's, fluorides, etc. cause water pollution. These pollutants are of concern to engineers, environmentalists and scientists. Due to the lack of freshwater, it is very important to recycle the wastewater after treatment to remove organic contaminates and heavy metal pollutants. Chemical precipitation, ion exchange, adsorption, filtration via membranes, flocculation, coagulation, flotation, and electrochemical techniques are just a few of the methods used to eliminate contaminants from wastewater. The most popular and effective among these is the ion exchange process. New generation hybrid materials, inorganic three‐dimensional matrices and synthetic organic resins are some examples of the different types of ion exchange resins. Most investigations have found that pseudo‐first and second order kinetic studies are important in the contaminant removal process. The isotherm model, which also incorporates the Langmuir, Freundlich, Dubinin Radushkevich, and Temkin equations, proved appropriate for most of the research. For an example, orgnic polymeric materials can maximum uptake capacity of 4.28 mmolg‐1 Cr(VI) and 1.97 mmolg‐1 As(V) respectively. The effectiveness of ion exchanger and its current trends in various environmental applications have been the main topics of this review article.

Abstract:

The adsorption of 115 emerging contaminants, mainly organic chemicals identified by the US Environmental Protection Agency's 2009 Contaminant Candidate List 3, was ranked using two published classical quantitative structure-activity relationship (QSAR) models and a newly developed quantum QSAR model. Approximately 75% of the investigated contaminants were predicted to be cost-effectively treatable, with an activated carbon usage rate below 10 mg/L. A limited experimental validation campaign was carried out by rapid small-scale column testing (RSSCT) using Lake Ontario water for eight selected compounds: 17β-estradiol, ibuprofen, diazinon, sulfamethoxazole, carbamazepine, 4-nonylphenol diethoxalyate, azithromycin and tylosin, with the activated carbon adsorption of the latter three having never been previously reported. The experimental results were consistent with the quantum chemistry model rankings.

Abstract:

Currently, public health is seriously threatened by the massive concentrations of emerging contaminants. Treating emerging contaminants in water using effective methods has become a major challenge worldwide. Photocatalytic technology, as an eco-friendly technology, has been recognized as an effective means of removing contaminants from water. Among the various photocatalysts, layered double hydroxides (LDHs), known as hydrotalcite-like materials, have been explored extensively in photocatalytic reactions due to their switchable properties and the large surface areas of their unique two-dimensional structures. In this article, recent advances in the photocatalytic degradation of emerging contaminants by LDH-based photocatalysts are reviewed. Firstly, the fundamental principles of the photocatalytic degradation of emerging contaminants using LDH-based materials are briefly introduced. Various LDHs applied in the photocatalytic degradation of emerging contaminants are broadly summarized into four types: pure-phase LDHs, interlayer-modified LDHs, LDH-based composites, and layered double oxides (LDOs). Moreover, the synthesis process and catalytic mechanism of LDH-based photocatalysts are also reviewed. An outlook on the problems and future development of LDH-based photocatalysts in water remediation is provided at the end.

Abstract:

The increasing disposal of emerging contaminants in the environment is a worldwide concern due to environmental impacts, such as toxicity, hormonal disorders, and bioaccumulation. The persistence of these pollutants in water bodies makes conventional pollutant removal techniques inefficient or partial, thus requiring the development of new, more effective, sustainable remediation technologies. Therefore, chitosan-based materials have emerged as a promising alternative for application in catalysis and contaminant removal. The biopolymer has functional properties that make it an excellent adsorbent capable of removing more specific pollutants, such as pharmaceuticals, microplastics, agricultural pesticides, and perfluoroalkyl and poly-fluoroalkyl substances, which are increasingly in evidence today. Therefore, this review of recent and advanced research into using chitosan to manufacture catalytic and adsorption materials offers an innovative approach to treating contaminants in aqueous environments, significantly reducing their presence and impact. It discusses the advantages of using chitosan as an adsorbent and catalyst and its role as a support for catalysts and biocatalysts. In addition, the review highlights the diversity of the physical forms of chitosan, such as particles, membranes, and hydrogels, and its possible chemical modifications, highlighting its effectiveness in catalytic applications and the removal of a wide range of emerging contaminants.
