Marie Noele Croteau, Ph.D.
Marie came to the USGS in September 2002 as a postdoctoral fellow to study the bioavailability and bioaccumulation of metals in freshwater food webs. Her work focused on understanding how metals are transferred through food webs and how trophic position in a food web influences exposure to metals.
Marie used nitrogen and carbon stable isotopes to show that cadmium, in contrast to copper, could be magnified along certain freshwater food webs. This suggests that processes that drive Cd trophic transfer are more complex than that of organo-metals, metalloids and organic contaminants.
In addition to her work on metal trophic transfer, she refined an approach that involves the use stable metal isotopes (rather than radioisotopes) to describe accumulation and loss dynamics in freshwater invertebrates. Characterization of bioaccumulation dynamics is critical to understanding risks associated with contaminant exposure in organisms. For instance, this tracing technique allowed showing that a slow rate constant of loss for Cu likely explains the elevated levels of this toxic trace metal found in molluscs in nature, and that diet is an important bioaccumulation pathway for metals for several aquatic species.
She used biodynamic modeling and the enriched stable isotope tracers in novel ways to understand the fate and effects of nanosized metals in aquatic organisms as well as to investigate how the geochemical properties of mineral particles consumed by organisms affect their bioavailability.

Bioavailability and bioaccumulation of metal-based engineered nanomaterials in aquatic environments: Concepts and processes
Bioavailability of Me-ENMs to aquatic organisms links their release into the environment to ecological implications. Close examination shows some important differences in the conceptual models that define bioavailability for metals and Me-ENMs. Metals are delivered to aquatic animals from Me-ENMs via water, ingestion, and incidental surface exposure. Both metal released from the Me-ENM and uptake

Dietary bioavailability of Cu adsorbed to colloidal hydrous ferric oxide
The dietary bioavailability of copper (Cu) adsorbed to synthetic colloidal hydrous ferric oxide (HFO) was evaluated from the assimilation of 65Cu by two benthic grazers, a gastropod and a larval mayfly. HFO was synthesized, labeled with 65Cu to achieve a Cu/Fe ratio comparable to that determined in naturally formed HFO, and then aged. The labeled colloids were mixed with a food source (the diatom

Isotopically modified nanoparticles for enhanced detection in bioaccumulation studies
This work presents results on synthesis of isotopically enriched (99% 65Cu) copper oxide nanoparticles and its application in ecotoxicological studies. 65CuO nanoparticles were synthesized as spheres (7 nm) and rods (7 × 40 nm). Significant differences were observed between the reactivity and dissolution of spherical and rod shaped nanoparticles. The extreme sensitivity of the stable isotope traci

Silver bioaccumulation dynamics in a freshwater invertebrate after aqueous and dietary exposures to nanosized and ionic Ag
We compared silver (Ag) bioavailability and toxicity to a freshwater gastropod after exposure to ionic silver (Ag+) and to Ag nanoparticles (Ag NPs) capped with citrate or with humic acid. Silver form, exposure route, and capping agent influence Ag bioaccumulation dynamics in Lymnaea stagnalis. Snails efficiently accumulated Ag from all forms after either aqueous or dietary exposure.

Synthesis of isotopically modified ZnO nanoparticles and their potential as nanotoxicity tracers
Understanding the behavior of engineered nanoparticles in the environment and within organisms is perhaps the biggest obstacle to the safe development of nanotechnologies. Reliable tracing is a particular issue for nanoparticles such as ZnO, because Zn is an essential element and a common pollutant thus present at elevated background concentrations. We synthesized isotopically enriched (89.6%) wit

A novel approach reveals that zinc oxide nanoparticles are bioavailable and toxic after dietary exposures
If engineered nanomaterials are released into the environment, some are likely to end up associated with the food of animals due to aggregation and sorption processes. However, few studies have considered dietary exposure of nanomaterials. Here we show that zinc (Zn) from isotopically modified 67ZnO particles is efficiently assimilated by freshwater snails when ingested with food. The 67Zn from na

Measurement and modeling of polychlorinated biphenyl bioaccumulation from sediment for the marine polychaete neanthes arenaceodentata and response to sorbent amendment
Bioaccumulation rates of polychlorinated biphenyls (PCBs) for the marine polychaete Neanthes arenaceodentata were characterized, including PCB uptake rates from water and sediment, and the effect of sorbent amendment to the sediment on PCB bioavailability, organism growth, and lipid content. Physiological parameters were incorporated into a biodynamic model to predict contaminant uptake. The resul

Predicting dietborne metal toxicity from metal influxes
Dietborne metal uptake prevails for many species in nature. However, the links between dietary metal exposure and toxicity are not well understood. Sources of uncertainty include the lack of suitable tracers to quantify exposure for metals such as copper, the difficulty to assess dietary processes such as food ingestion rate, and the complexity to link metal bioaccumulation and effects.

A biomonitor for tracking changes in the availability of lakewater cadmium over space and time
Determining the exposure of organisms to contaminants is a key component of Ecological Risk Assessments (ERAs). Effective estimates of exposure consider not only the total concentrations of contaminants in an organism's surroundings but also the availability of the contaminants to organisms. Contaminant availability can be inferred from mechanistic models and verified by measurements of contaminan

A biodynamic understanding of dietborne metal uptake by a freshwater invertebrate
Aquatic organisms accumulate metals from dissolved and particulate phases. Dietborne metal uptake likely prevails in nature, but the physiological processes governing metal bioaccumulation from diet are not fully understood. We characterize dietborne copper, cadmium, and nickel uptake by a freshwater gastropod (Lymnaea stagnalis) both in terms of biodynamics and membrane transport characteristics.

Determining metal assimilation efficiency in aquatic invertebrates using enriched stable metal isotope tracers
We employ a novel approach that combines pulse-chase feeding and multi-labelled stable isotopes to determine gut passage time (GPT), gut retention time (GRT), food ingestion rate (IR) and assimilation efficiency (AE) of three trace elements for a freshwater gastropod. Lettuce isotopically enriched in 53Cr, 65Cu and 106Cd was fed for 2 h to Lymnaea stagnalis. The release of tracers in feces and wat

Characterizing dissolved Cu and Cd uptake in terms of the biotic ligand and biodynamics using enriched stable isotopes
The biotic ligand model considers the biological and geochemical complexities that affect metal exposure. It relates toxicity to the fraction of physiological active sites impacted by reactive metal species. The biodynamic model is a complementary construct that predicts bioaccumulation and assumes that toxicity occurs when influx rates exceed rates of loss and detoxification. In this paper we pre
