Tracing Heavy Metal Contamination in Salt Marshes, Estuaries, and Coastal Systems: Sources, Fate, and Ecological Impacts
Session ID#: 258070
Session Description:
Salt marshes, estuaries, and coastal systems are key depositional zones for metal contaminants.
Inputs from legacy mining, urban runoff, industrial activity, fires, transportation, and
infrastructure failures can lead to persistent metal accumulation and complex cycling among
dissolved, particulate, sedimentary, and biological pools. Understanding these processes is
essential for evaluating ecological risks to benthic and pelagic communities and informing
remediation and regulatory strategies.
This session aims to highlight recent advances in understanding the sources, transport, and fate
of metal contaminants in coastal systems, including estuaries and salt marshes. We aim to engage
scientists from a wide range of disciplines and geographic regions. We welcome contributions
focused on sediment–water exchange, metal partitioning, redox transformations, microbial
interactions, metal bioavailability, and long-term monitoring programs. Studies employing
metals as geochemical tracers of contamination, passive samplers, novel in situ technologies,
mesocosm experiments, and mechanistic models are encouraged. We are also interested in
research addressing transient or pulsed contamination events—such as wildfires or industrial
accidents which are often poorly resolved using conventional monitoring techniques.
