LC-MS/MS Measurement of Nanomaterial Induced Genotoxicity in Isolated DNA

November 24, 2015
Author(s)
Bryant C. Nelson, Elijah J. Petersen, Pawel Jaruga, M Miral Dizdar
Making accurate measurements of the environmental fate and environmental and biological effects of engineered nanomaterials (ENMs) is critical for reliable risk assessment of these materials. However, the unique behaviors of ENMs may cause artifacts in

Degradation of 14C-labeled Graphene via Fenton Reaction: Reaction rates, characterization of reaction products, and potential ecological effects

September 28, 2015
Author(s)
Yiping Feng, Elijah Petersen, Kun Lu, Xiangke Guo, Shixiang Gao, Liang Mao
Graphene has attracted considerable interest due to its numerous emerging applications. It is inevitable that graphene will be released into the environment during their transportation and usage in consumer products, but their ecological risks are still

ADAPTING OECD AQUATIC TOXICITY TESTS FOR USE WITH MANUFACTURED NANOMATERIALS: KEY ISSUES, CONSENSUS RECOMMENDATIONS, AND DATA GAPS

July 16, 2015
Author(s)
Elijah J. Petersen, Alan Kennedy, Greg Goss, Ho Kay, Jamie Lead, Shannon Hanna, Kerstin Hund-Rinke, Brian Mader, Nicholas Manier, Pascal Pandard, Edward Salinas, Kathrin Schwirn, Doris Voelker
The unique or enhanced properties of manufactured nanomaterials (MNs) suggest that their use in nano-enabled products will continue to increase in the future. This will result in increasing potential for human and environmental exposure to MNs, during

A perspective on the use of nanomaterial categorization for risk assessment and regulatory decision-making

March 19, 2015
Author(s)
Hilary Godwin, Catherine Nameth, David Avery, Lynn Bergeson, Elizabeth Beryt, Wlliam Boyd, Amy Clippinger, Christine Hendren, Patricia Holden, Keith Houck, Agnes Kane, Frederick Klaessig, Tong Kooi Lee, Iseult Lynch, Timothy Malloy, Mary Miller, Gunter Oberdorster, Elijah Petersen, Vicki Stone, Andre Nel
For nanotechnology to meet its potential as a revolutionary and sustainable technology, it is necessary that engineered nanomaterials (ENMs) and nano-enabled products that are safe and effective make it to the marketplace. This process is frequently

The Use of Cause-and-Effect Analysis to Design a High Quality Nano-Cyto-Toxicology Assay

December 4, 2014
Author(s)
Matthias Rosslein, John T. Elliott, Marc L. Salit, Elijah Petersen, Cordula Hirsch, Harald Krug, Peter Wick
An important consideration in developing standards and regulations that govern the production and use of commercial nanoscale materials is the development of robust and reliable measurements to assess potential biological effects of these nanomaterials

Assessment of Crude Oil and a Dispersant in a Simulated Spartina alterniflora Salt Marsh Ecosystem

December 1, 2014
Author(s)
P Key, K Chung, C Cooksey, DeLorenzo M, M Fulton, D Greenfield, T Greig, J Hylund, Bryant C. Nelson, Varun Patel, P Pennington, Elijah Petersen, E Wirth
NOAA's Environmental Sensitivity Index (ESI) lists saltmarshes along the Atlantic and Gulf Coasts as the most vulnerable habitat to oil spills. As a result of the Deepwater Horizon offshore drilling rig accident, more that 200 million gallons of crude oil

The DNA Damaging Potential of Photoactivated P25 Titanium Dioxide Nanoparticles

September 30, 2014
Author(s)
Elijah Petersen, Vytas Reipa, Stephanie S. Watson, Deborah Jacobs, Savelas A. Rabb, Bryant C. Nelson
Titanium dioxide nanoparticles (TiO2 NPs) are found in numerous commercial and personal care products. Thus, it is necessary to understand and characterize their potential environmental health and safety risks. It is well known that photoactivated TiO2 NPs

Using Single Particle ICP-MS as a Tool for Understanding Metallic Nanoparticle Transformation during Nanotoxicity Assays

July 1, 2014
Author(s)
Monique E. Johnson, Shannon Hanna, Antonio R. Montoro Bustos, Bryant C. Nelson, Elijah J. Petersen, Lee L. Yu
The advent of engineered nanoparticles (ENPs) and their increased use has remarkably improved the performance of basic materials and consumer products, but has also increased the potential for ENP release into the environment. Technical procedures, more
