Arsenic in clay samples used for ceramic water filters
We collaborated for a number of years with organizations in SE Asia to measure the presence of arsenic in clay water filters. See Arsenic page for a more complete description.
Restoration of an Urban Stream - Monitoring improvements during greenway development
Students and faculty worked together with Ecosystems Services LLC to assess the current state of Black's Run, and urban stream that is the site of a planned greenway project. See further description of this urban stream project.
Mercury in the South River, Virginia
Major work with the South River Science Team utilized caged clams to help define the pattern of mercury contamination in the South River. This worked helped to identify areas of most concern in the river, and provided methodological data on the use of clams as environmental monitors.Neufeld, D.S.G. (2010). Mercury Accumulation in Caged Corbicula: Rate of Uptake and Seasonal Variation. Environmental Monitoring and Assessment. 168: 385-396.Air Pollution Phnom Penh, Cambodia
Work with colleagues at Buffalo State College demonstrated the distribution of fire and coarse air particulates in Phnom Penh, identifying areas of the city of concern due to high traffic inputs and unpaved roads.Vermette, S.J., Bernosky, J., and Graber Neufeld, D. (2011). Mapping of Airborne Particulates in Phnom Penh, Cambodia: Comparisons with Bangkok, Thailand and Phoenix, Arizona. Asian Journal of Water, Environment and Pollution. 8(2): 1-9.Drinking Water and Sewage in Cambodia and Thailand
Additional work in Cambodia and Thailand focused on drinking water and sewage treatment, and was funded by an NSF IRES grant with colleagues at Buffalo State College. Examples of several projects are shown on the posters below (click for larger images).
Organic Transport in Insect Malpighian Tubules - Importance in Pesticide Resistance.
Three years of work was funded by the Jeffress Foundation, and worked towards understanding the mechanisms and importance of organics transport in the kidney of insects. This work demonstrated that the organic anion transport process in crickets can handle several pesticides, and thus is a potential mechanism of pesticide resistance in insects.Neufeld, D.S.G., Kauffman, R., and Kurtz, Z. (2005). Specificity of the Fluorescein Transport Process in Malpighian Tubules of the Cricket, Acheta domesticus. J. exp. Biol. 208, 2227-2236.Metal Chelator Handling by the Kidney
Work at the University of Arizona helped to elucidate how the mammalian kidney handles DMPS, a metal chelator with potential therapeutic applications.
