- 27 January 2010
We combined N, C, and Hg stable isotope measurements to identify the most important factors that influence MeHg accumulation in fish from the northern Gulf of Mexico (nGOM), and to determine if… Expand
Spatial heterogeneity of methane ebullition in a large tropical reservoir.

- 1 November 2011
Tropical reservoirs have been identified as important methane (CH(4)) sources to the atmosphere, primarily through turbine and downstream degassing. However, the importance of ebullition (gas… Expand
Characterization of zinc, lead, and cadmium in mine waste: implications for transport, exposure, and bioavailability.

We characterized the lability and bioaccessibility of Zn, Pb, and Cd in size-fractionated mine waste at the Tar Creek Superfund Site (Oklahoma) to assess the potential for metal transport, exposure,… Expand
Mercury bioaccumulation and trophic transfer in sympatric snapper species from the Gulf of Mexico.

- 1 October 2007
Consumption of marine fish is a major route of toxic methyl mercury (MeHg) exposure to ocean apex predators and human populations. Here we explore the influence of trophic structure on total mercury… Expand
Impact of a large tropical reservoir on riverine transport of sediment, carbon, and nutrients to downstream wetlands
- M. Kunz, A. Wüest, B. Wehrli, J. Landert, D. Senn
- Environmental Science, Geology
- 1 December 2011
Large dams can have major ecological and biogeochemical impacts on downstream ecosystems such as wetlands and riparian habitats. We examined sediment removal and carbon (C), nitrogen (N), and… Expand
Sediment accumulation and carbon, nitrogen, and phosphorus deposition in the large tropical reservoir Lake Kariba (Zambia/Zimbabwe)
- M. Kunz, F. Anselmetti, +4 authors D. Senn
- Geology
- 1 September 2011
Large dams affect the aquatic continuum from land to ocean by accumulating particles and nutrients in their reservoirs. We examined sediment cores to quantify sediment, organic carbon (OC), nitrogen… Expand
Nitrate Controls on Iron and Arsenic in an Urban Lake
Aquatic ecosystems are often contaminated by multiple substances. Nitrate, a common aquatic pollutant, strongly influenced the cycling of arsenic (As) under anoxic conditions in urban Upper Mystic… Expand
Fish Consumption and Mercury Exposure among Louisiana Recreational Anglers

BACKGROUND
Methylmercury (MeHg) exposure assessments among average fish consumers in the United States may underestimate exposures among U.S. subpopulations with high intakes of regionally specific… Expand
Sources and fates of heavy metals in a mining-impacted stream: temporal variability and the role of iron oxides.
