Special Issue Information
Dear Colleagues,
We are pleased to invite you to contribute to this Special Issue, titled "Transformation and Associated Isotope Kinetics of Halogenated Organic Pollutants in the Environment and Living Organisms". Halogenated organic pollutants (HOPs), including polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), chlorinated organophosphate esters (Cl-OPEs) and per- and polyfluoroalkyl substances (PFASs), represent a class of pervasive and persistent environmental contaminants. They have been posing significant ecotoxicological risks and long-term threats to human health. Elucidating their transformation processes in both abiotic and biotic systems is essential for assessing their environmental fate and ecological risks. In recent years, compound-specific isotope analysis (CSIA), particularly dual- or multi-dimensional CSIA, has emerged as a powerful tool for investigating the biogeochemical processes of HOPs in the environment. By measuring the isotopic composition variations (e.g., carbon, hydrogen, chlorine, or bromine) within a molecule, CSIA provides direct evidence for source apportionment, transformation discrimination, and mechanism elucidation of HOPs.
This Special Issue aims to highlight recent advances in our understanding of the transformation and associated isotope kinetics of halogenated organic pollutants. We invite contributions that explore innovative analytical methods, field and laboratory studies on biotic and abiotic transformation processes, and theoretical models that integrate isotopic fractionation into assessments of environmental and biological fate. By bringing together cutting-edge research in this field, we hope to foster interdisciplinary dialogue and advance the application of compound-specific isotope analysis (CSIA) in environmental monitoring, remediation, and public health protection.
In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:
- Microbial and abiotic transformation mechanisms of halogenated organic pollutants and associated kinetic isotope effects;
- Isotopic fractionation during bioaccumulation, trophic transfer, and metabolism in living organisms;
- Field applications of compound-specific isotope analysis (CSIA) for source apportionment and transformation discrimination;
- Transformation kinetics and pathways of emerging halogenated contaminants;
- Methodological advances in CSIA.
