Monitoring and Biodegradation of Emerging Contaminants

About this Research Topic

Background

Emerging contaminants (ECs) are characterized by severe harmfulness, hidden risks, environmental persistence, widespread sources, and complex treatment challenges. They are prevalent in various environments, posing significant risks to ecosystems and human health, and have garnered substantial scientific and public attention. To effectively control EC pollution, stricter regulations, efficient treatment methods, and routine monitoring are essential. Microbial biotechnologies are commonly employed to remove ECs, although their halogenated functional groups contribute to strong ecological toxicity, complicating complete biodegradation by organisms. Therefore, it is crucial to reduce the toxicity of ECs and enhance the capacity of microorganisms to degrade them.

Even at concentrations as low as nanogram per liter, ECs can adversely affect human health and other organisms, causing issues such as endocrine disruption, mutagenesis, carcinogenesis, and congenital disorders. Rapid and accurate monitoring of EC contamination is urgently needed for environmental security. Many innovative bio-based technologies have been developed for monitoring ECs, with biosensors emerging as a promising approach due to their low cost, simplicity, rapid processing, sensitivity, and portability.

This Research Topic focuses on technological innovations for monitoring ECs, such as persistent organic pollutants, pharmaceuticals and personal care products, micro/nano-plastics, and antibiotic resistance genes in water, sediments, and soil. It also explores theoretical and technological advancements in microbial treatment of these ECs.

We invite articles that focus on, but are not limited to, the following themes:
• Enzyme-based, antibody-based, nucleic acid-based, and whole cell-based biosensors for ECs monitoring.
• Microbial treatment of ECs for removal or resource utilization.
• Molecular mechanisms of microbial toxicology related to ECs.
• Biodegradation pathways of ECs.
• Techniques or methods for predicting and evaluating the microbial toxicological of ECs.

Please note that the Microbiotechnology section does not consider submissions limited to descriptive studies and observational that are based on bioinformatic analyses or 'omics' data alone. For example, studies limited to sequencing and sequence analyses of nucleic acid extracts (i.e., 16S rRNA gene amplicon libraries, shot-gun genomic analyses “metagenomics”).

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
