TerraTherm has recently completed its final progress soil sampling effort of Phase 1 at the Solvents Recovery Service of New England, Inc. (SRSNE) Superfund site in Southington, Connecticut. The site's total target treatment zone covers an area of approximately 74,195 square feet and an approximate volume of 47,298 cubic yards; with Phase 1 and ...

Establishing environmental baseline case study

by Antea Group - USA  (Nov. 6, 2014)

Challenge: A major integrated oil company, intending to divest a portfolio of 68 retail petroleum facilities in the northwest United States, requested the services of Antea Group to conduct Phase II Environmental Site Assessments in order to establish an environmental baseline prior to selling the assets. Among the project-specific challenges were ...

Impact of environmentally based chemical hardness on uranium speciation and toxicity in six aquatic species

by John Wiley & Sons, Ltd.  (Dec. 5, 2014)

Treated effluent discharge from uranium (U) mines and mills elevates the concentration of U, calcium (Ca), magnesium (Mg) and sulfate (SO42‐) above natural levels in receiving waters. Many investigations on the effect of hardness on U toxicity were often experiments on the combined effect of changes in hardness, pH and alkalinity which do not ...

ANSI N13.1-2011 Stack Sampling Considerations

by HI-Q Environmental Products Company  (Sep. 20, 2014)

Background Nuclear facilities are required to follow industry standards for sampling stack effluents. Exposure of the general public to released radionuclides must be monitored as specified in US governmental regulations. The United States Environmental Protection Agency (USEPA) and the United States Nuclear Regulatory Commission (USNRC) have the ...

The influence of environmental and social sustainability practices on firms’ performance: an empirical study of the dairy product sector in Goiás (Brazil)

by Inderscience Publishers  (Oct. 23, 2014)

Environmental and social sustainability have been major social and political issues in recent times. This study aims to analyse the relationship between governments’ socio-environmental policies and firms’ economic and socio-environmental performance. To achieve this main objective, a questionnaire was designed and addressed to the CEOs of firms ...

Direct detection of Mycobacterium avium in environmental water and scale samples by loop-mediated isothermal amplification

by IWA Publishing  (Jun. 18, 2014)

We previously demonstrated the colonization of Mycobacterium avium complex in bathrooms by the conventional culture method. In the present study, we aimed to directly detect M. avium organisms in the environment using loop-mediated isothermal amplification (LAMP), and to demonstrate the efficacy of LAMP by comparing the results with those ...

Biodiversity Detectives Solve Mysteries with Environmental DNA

by Ensia  (Aug. 4, 2014)

For years, Monterey Bay Aquarium’s 1.2 million gallon main tank has been a source of thrill for visitors seeking fish-eye views of life in the pounding Pacific Ocean right outside its doors. Now, thanks to advances in DNA sequencing, it’s also becoming a model for how to survey life inthat vast ocean with just a few glasses of water. ...

Evaluating cost when selecting performance reference compounds (PRCs) for the environmental deployment of polyethylene passive samplers

by John Wiley & Sons, Ltd.  (Sep. 19, 2014)

A challenge in environmental passive sampling is determining when equilibrium is achieved between the sampler, target contaminants, and environmental phases. A common approach is the use of performance reference compounds (PRCs) to estimate target contaminant sampling rates and indicate degree of sampler equilibrium. One logistical issue ...

Venerupis decussata under environmentally relevant lead concentrations: Bioconcentration, tolerance and biochemical alterations

by John Wiley & Sons, Ltd.  (Sep. 8, 2014)

The edible clam Venerupis decussata is widely distributed in European aquatic systems, some of them under strong anthropogenic pressure, which can contribute to trophic transfer of xenobiotics to humans. Taking into account this rationale, the present study focused on the tolerance, bioconcentration and bio chemical responses of V. decussata ...

SupelMIP SPE for Sample Cleanup and Analysis of Food and Environmental Contaminants

by Sigma-Aldrich/Supelco  (Sep. 5, 2013)

MIP SPE was successfully used for extraction of multiple classes of food and environmental contaminants from difficult matrices, such as egg, oil and flour. • Six nitroimidazoles were extracted from egg and milk with recoveries typically over 90%. • Among NSAIDs compounds, acidic compounds gave good recoveries between 100-115% while ...
