- Bioavailability, toxicity, and bioaccumulation of quantum dot nanoparticles to the amphipod Leptocheirus plumulosusBrian P Jackson
Trace Element Analysis Core, Department of Earth Sciences, Dartmouth College, Hanover, New Hampshire 03755, United States
Environ Sci Technol 46:5550-6. 2012..This study suggests QDs are accumulated to a greater extent than the dissolved ion and could lead to trophic transfer. QDs ingested with algae are bioavailable and result in toxicity, which is not observed in the absence of algae...
- Arsenic, organic foods, and brown rice syrupBrian P Jackson
Trace Element Analysis Core Laboratory, Department of Earth Sciences, Dartmouth College, Hanover, New Hampshire 03755, USA
Environ Health Perspect 120:623-6. 2012..Organic brown rice syrup (OBRS) is used as a sweetener in organic food products as an alternative to high-fructose corn syrup. We hypothesized that OBRS introduces As into these products...
- Synchrotron X-ray 2D and 3D elemental imaging of CdSe/ZnS quantum dot nanoparticles in Daphnia magnaBrian P Jackson
Trace Element Analysis Laboratory, Department of Earth Sciences, Dartmouth College, Hanover, NH 03755, USA
Anal Bioanal Chem 394:911-7. 2009..e., there was no effect of QD size. 3D tomography confirmed that the QDs were exclusively in the gut area of the organism. It is possible that the QDs aggregated and were therefore too large to cross the gut wall...
- Low-level mercury speciation in freshwaters by isotope dilution GC-ICP-MSBrian Jackson
Trace Element Analysis Core, Department of Earth Sciences, Dartmouth College, Hanover, New Hampshire 03755, USA
Environ Sci Technol 43:2463-9. 2009..006 ng L(-1) at concentrations as low as 0.014 ng L(-1)...
- Rice consumption contributes to arsenic exposure in US womenDiane Gilbert-Diamond
Children s Environmental Health and Disease Prevention Center at Dartmouth, Hanover, NH 03755, USA
Proc Natl Acad Sci U S A 108:20656-60. 2011..Our findings along with others indicate that rice consumption should be considered when designing arsenic reduction strategies in the United States...
- Mercury bioavailability and bioaccumulation in estuarine food webs in the Gulf of MaineCelia Y Chen
Department of Biological Sciences, HB 6044 Gilman Hall, Dartmouth College, Hanover, New Hampshire 03755, USA
Environ Sci Technol 43:1804-10. 2009..These results reveal the importance of both biogeochemical and ecological factors in determining the bioavailability and trophic transfer of MeHg in estuarine food webs...
- Mercury speciation and total trace element determination of low-biomass biological samplesVivien F Taylor
Trace Element Analysis Core, Dartmouth College, 6105 Fairchild, Hanover, NH 03755, USA
Anal Bioanal Chem 392:1283-90. 2008..The method also provides further validation of speciation data, by corroborating the sum of the Hg species concentrations with the total Hg concentration...
- Laboratory diet profoundly alters gene expression and confounds genomic analysis in mouse liver and lungCourtney D Kozul
Department of Pharmacology and Toxicology, Dartmouth Medical School, 7650 Remsen Building, Hanover, NH 03755 3835, United States Center for Environmental Health Sciences, Dartmouth Medical School, Hanover, NH 03755, United States
Chem Biol Interact 173:129-40. 2008..These findings indicate that the use of non-purified diets may profoundly alter observable patterns of change induced by arsenic and, likely, by other experimental treatments, particularly, altering gene and protein expression...
