A comparison of activated carbon remediation success in floodplain soils contaminated with DDT and its metabolites using ex situ and in situ experimentation

Autor: Amanda D. Harwood, Samuel A. Nutile, Adam M. Simpson

Publikováno v: Environmental pollution (Barking, Essex : 1987). 295

Remediation of hydrophobic organic contaminants using activated carbon is an effective means by which to clean up contaminated areas. Predicting remediation success using laboratory experimentation with soil, however, is unclear. Current remediation

Utility of normalizing Tenax extractable concentrations for phase volume in application as an environmental screening tool

Autor: Samuel A. Nutile, Federico L. Sinche, Amanda D. Harwood

Publikováno v: Chemosphere. 261

Bioaccessibility-based extraction tools, such as single-point Tenax extractions (SPTEs), provide cost-effective and accurate estimates of bioaccumulation and toxicity of hydrophobic organic contaminants during environmental sampling. Use of SPTEs as

Publikováno v: Environmental Monitoring and Assessment. 192

The Pine River, in the central, Lower Peninsula region of Michigan, has a long history of contamination. Livestock facilities and manure application sites along the Pine River and its tributaries have led to elevated nutrient levels. In addition to n

The Value of Using Multiple Metrics to Evaluate PCB Exposure

Autor: Michael J. Lydy, Marc A. Mills, Amanda D. Harwood, Samuel A. Nutile, Kara E. Huff Hartz, Megan C. Archer, Jim E. Garvey

Publikováno v: Archives of Environmental Contamination and Toxicology. 74:361-371

Current methods for evaluating exposure in ecosystems contaminated with hydrophobic organic contaminants typically focus on sediment exposure. However, a comprehensive environmental assessment requires a more holistic approach that not only estimates

Methodological and Environmental Impacts on Bioaccessibility Estimates Provided by Single-Point Tenax Extractions

Autor: Samuel A. Nutile, Peter F. Landrum, Amanda D. Harwood, Michael J. Lydy, Kara E. Huff Hartz, Federico L. Sinche

Publikováno v: Archives of Environmental Contamination and Toxicology. 72:612-621

Single-point Tenax extractions (SPTEs) of hydrophobic organic contaminants provide estimates of bioaccessibility through consistent measures of the chemical concentration initially in the rapidly desorbing fraction in sediment (C rapT0), such that a

The robustness of single-point Tenax extractions of pyrethroids: Effects of the Tenax to organic carbon mass ratio on exposure estimates

Autor: Samuel A. Nutile, Amanda D. Harwood, Kara E. Huff Hartz, Federico L. Sinche, Peter F. Landrum, Michael J. Lydy

Publikováno v: Chemosphere. 171:308-317

Use of Tenax extractable concentrations to estimate biological exposure to hydrophobic organic contaminants is well documented, yet method variation exists between studies, specifically in the ratio of Tenax mass to organic carbon mass in the sedimen

Fate and risk of atrazine and sulfentrazone to nontarget species at an agriculture site

Autor: Tracye M. Murphy, Jordan L. Thorngren, Courtney Y. Fung, Amanda D. Harwood, Kara E. Huff Hartz, Michael J. Lydy

Publikováno v: Environmental Toxicology and Chemistry. 36:1301-1310

The present study evaluated the risk associated with the application and co-occurrence of 2 herbicides, atrazine and sulfentrazone, applied to a 32-ha corn and soybean rotational field. Field concentrations of the compounds were measured in soil, run

Evaluating toxicity risk in sediments after remediation at a Superfund megasite using a Triad approach

Autor: M. Megan Woller-Skar, Grace E. Sutherland, Amanda D. Harwood, Murray C. Borrello, Michael J. Lydy

Publikováno v: Environmental Monitoring and Assessment. 191

The Pine River downstream of the Velsicol Superfund site has been contaminated with various hydrophobic organic pollutants for more than 50 years. Remediation and sediment dredging near the site began in spring of 1999, and was completed in 2006. In
