EMERGING POLLUTANTS: OCCURRENCE, FATE, IMPACTS, AND APPROACHES FOR DETECTION (2025)

Classification, Potential Routes and Risk of Emerging Pollutants/Contaminant

Emerging Contaminants, 2021

Emerging contaminants (ECs), encompass both natural and synthetic chemicals that are present or transformed to new chemical compounds in water bodies across the globe. They are presently not checked in the environment but poses a serious health threat to human and ecosystem as well as environmental damage. ECs are released into environment during the anthropogenic activities such as water treatments, fumigation, farming etc. More than 1036 ECs and their biotransformation have been identified by the NORMAN project, established in 2005 by the European Commission. They were further classified into different categorizes/classes including disinfection by-products, pesticides, pharmaceuticals and personal care products, nanomaterials, benzotriazoles, benzothiazoles among others. The potential sources, path route and their health implication on human were also discussed. The presence of ECs in our environments is global issue that requires urgent attention.

Emerging Pollutants- A review of current understanding and future scenario

World Journal Of Advanced Research and Reviews, 2022

A recently identified community of chemicals found in aquatic ecosystems are pollutants of increasing concern or, literally, emerging pollutants (EPs). It was only the advances in analytical techniques that enabled the identification of these pollutants even at low concentrations. The persistent discovery of new chemicals prompts concerns about their origin routes, their destiny, their transport, their transition and their effect on the aquatic ecosystem. As new chemical substances are continually being generated and scientific research optimizes its awareness of existing and previous pollutants, pollutants of increasing concerns will stay a moving target. EPs primarily originating from the disposal of urban and industrial wastewater effluents, are widespread in the aquatic ecosystems. Owing to the potential biological effect on organisms within the ecosystem, their existence is of worry. A holistic approach to sampling is needed in order to understand their fate and transformations in wastewater and ecosystem. This implies the attainment of relevant evidence and promotes a deeper interpretation of spatiotemporal pollutant patterns and occurrence. During treating of wastewater, owing to more planning criteria and absence of good analytical techniques, there is a shortage of residual pollutants study. This leads to under-reported analysis of many EPs joining wastewater treatment works and the aquatic ecosystem. Sludge can hold concentrations of certain chemicals, during the treatment of wastewater that ends up being applied to agriculture without analysis for EPs. Hence a framework for environmental reporting that is more holistic is needed, so that the destiny and effect of EPs are explored in all environmental systems. This review discusses current understanding of EPs and provides recommendations for better future analysis.

Emerging Contaminants in the Environment: How Can We Identify the Problems?

Norman Newsletter | Issue 4 | May 2008 Copies can be obtained at http://www.norman-network.net OR www.emerging-pollutants.net |1| The aim of the activities of the NORMAN network is to enhance the exchange of information on emerging environmental substances, and to encourage the validation and harmonisation of common measurement methods and monitoring tools so that the requirements of risk assessors and risk managers can be better met. The NORMAN newsletter is for everyone interested in emerging substances in the environment. This newsletter keeps you up to date on scientific advances in this area and highlights the activities and events of the EU NORMAN Network.

Emerging Pollutants – Part I: Occurrence, Fate and Transport

Water Environment Research, 2012

Part I: Occurrence, Fate, and Transport (this literature review) compiles research from 2013 investigating emerging pollutants in wastewater and environmental waters and the sources of emerging pollutants. The paper summarizes important findings on environmental aquatic occurrence, persistence and transport of emerging pollutants in the environment, monitoring approaches, modeling, and regulatory discussions. The paper further mentions updates in our understanding of the toxicological impacts of these compounds where relevant specifically to wastewater. Finally, the paper speaks to the environmental sinks and degradation of pollutants. Part II: Treatment (the companion to this review) includes discussion of water and wastewater treatment technologies on emerging pollutants.

Emerging pollutants in the environment: present and future challenges in biomonitoring, ecological risks and bioremediation

New biotechnology, 2015

Emerging pollutants reach the environment from various anthropogenic sources and are distributed throughout environmental matrices. Although great advances have been made in the detection and analysis of trace pollutants during recent decades, due to the continued development and refinement of specific techniques, a wide array of undetected contaminants of emerging environmental concern need to be identified and quantified in various environmental components and biological tissues. These pollutants may be mobile and persistent in air, water, soil, sediments and ecological receptors even at low concentrations. Robust data on their fate and behaviour in the environment, as well as on threats to ecological and human health, are still lacking. Moreover, the ecotoxicological significance of some emerging micropollutants remains largely unknown, because satisfactory data to determine their risk often do not exist. This paper discusses the fate, behaviour, (bio)monitoring, environmental an...

Transport and dynamics of toxic pollutants in the natural environment and their effect on human health: research gaps and challenge

Environmental Geochemistry and Health, 2009

The source–pathway–receptor (SPR) approach to human exposure and risk assessment contains considerable uncertainty when using the refined modelling approaches to pollutant transport and dispersal, not least in how compounds of concern might be prioritised, proxy or indicator substances identified and the basic environmental and toxicological data collected. The impact of external environmental variables, urban systems and lifestyle is still poorly understood. This determines exposure of individuals and there are a number of methods being developed to provide more reliable spatial assessments. Within the human body, the dynamics of pollutants and effects on target organs from diffuse, transient sources of exposure sets ambitious challenges for traditional risk assessment approaches. Considerable potential exists in the application of, e.g. physiologically based pharmacokinetic (PBPK) models. The reduction in uncertainties associated with the effects of contaminants on humans, transport and dynamics influencing exposure, implications of adult versus child exposure and lifestyle and the development of realistic toxicological and exposure data are all highlighted as urgent research needs. The potential to integrate environmental with toxicological models provides the next phase of research opportunity and should be used to drive empirical and model assessments.
