Dartmouth Superfund Research Program researchers Margaret Karagas and Brian Jackson are co-authors of the paper Validity of Retrospective Occupational Exposure Estimates of Lead and Manganese in a Case-Control Study. The study used toenail samples as bioindicators of exposure and “assessed whether work tasks and expert assessments of occupational metal exposure obtained from personal interviews were associated with lead and manganese concentrations”. The paper is published in the journal Occupational & Environmental Medicine.
Dartmouth Superfund Program researchers Celia Chen, Kate Buckman and Vivien Taylor are co-authors of a paper that “examined the individual and combined effects of temperature, sediment organic carbon, and salinity on the bioaccumulation of MeHg in an estuarine amphipod, Leptocheirus plumulosus, when exposed to sediment from two locations in the Gulf of Maine (Kittery and Bass Harbor) that contained different levels of MeHg and organic carbon.” The paper, Effects of Temperature, Salinity, and Sediment Organic Carbon on Methylmercury Bioaccumulation in an Estuarine Amphipod, is published in Science of the Total Environment.
Dartmouth Superfund Program Director and researcher Celia Chen is co-author of the paper, Factors Affecting MeHg Bioaccumulation in Stream Biota: the Role of Dissolved Organic Carbon and Diet. The paper, published in the journal Ecotoxicology, studied the “effects of water chemistry and diet on mercury bioaccumulation in stream biota.”
Dartmouth Superfund Program researcher Brian Jackson is co-author of a study that “…tests the hypothesis that higher levels of exposure to PAHs and PAH-DNA adducts in placenta of women living near Superfund sites contribute to the increased rate of PTBs” (pre term births). The paper, Association Between Elevated Placental Polycyclic Aromatic Hydrocarbons (PAHs) and PAH-DNA Adducts from Superfund Sites in Harris County, and Increased Risk of Preterm Birth (PTB), is published in the journal Biochemical and Biophysical Research Communications.
Dartmouth Superfund Program researchers Kate Buckman and Vivien Taylor are co-authors of a study that “…demonstrates that vernal pools are important hotspots where amphibians bioaccumulate MeHg, which may then be transferred to terrestrial ecosystems.” The paper, Bioaccumulation of Methylmercury in Wood Frogs and Spotted Salamanders in Vermont Vernal Pools, is published in Ecotoxicology.
Dartmouth Superfund Program researchers Tracy Punshon, Brian Jackson and Margaret Karagas are co-authors of a paper that examines relationships between placental concentrations of cadmium (Cd), arsenic (As), mercury (Hg) and lead (Pb) and measures of placental growth and functioning as part of the New Hampshire Birth Cohort Study. Placental Metal Concentrations in Relation to Placental Growth, Efficiency and Birth Weight

Dartmouth SRP Trainee Antonio Signes-Pastor (lead author) and Researcher Margaret Karagas are co-authors of the paper Inorganic arsenic exposure and neuropsychological development of children of 4–5years of age living in Spain. The study, published in the journal Environmental Research,” …suggests that relatively low inorganic As exposure may impair children’s neuropsychological development and that sex-related differences may be present in susceptibility to iAs related effects.”
