A Cleaner Energy Future

by ASTM International  (Oct. 16, 2014)

As renewable energy plays an increasingly important role in the world’s energy portfolio, the standards of ASTM International Committee E44 are helping to pave the way for innovation in clean energy sources. A growing population and improving living standards around the world are causing significant increases in energy demand and competition ...

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. ...

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 ...

Urban wastewater effluent increases antibiotic resistance gene concentrations in a receiving northern european river

by John Wiley & Sons, Ltd.  (Oct. 20, 2014)

Antibiotic resistant bacteria are an emerging global problem which threatens to undermine important advances in modern medicine. The environment is likely to play an important role in dissemination of antibiotic resistance genes (ARGs) among both environmental and pathogenic bacteria. Wastewater treatment plants (WWTPs) accumulate both chemical ...

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 ...

by Eijkelkamp Agrisearch Equipment  (Jul. 23, 2014)

Michael Bird of the James Cook University (Centre for Tropical Environmental & Sustainability Sciences) in Cairns and his team are looking for 100.000 year old records of environmental change in the north of Australia. Michael Bird uses Eijkelkamp equipment to take sediment samples. Check the ...

Characterization of trenbolone acetate and estradiol metabolite excretion profiles in implanted steers

by John Wiley & Sons, Ltd.  (Sep. 22, 2014)

Exogenous growth promoters have been used in United States beef cattle production for over 50 years. The environmental fate and transport of steroid growth promoters suggest potential for endocrine disrupting effects among ecological receptors; however, the initial excretion of steroid metabolites from cattle administered growth promoters has ...

Sorption of per‐and polyfluoroalkyl substances (PFASs) on filter media: Implications for phase partitioning studies

by John Wiley & Sons, Ltd.  (Sep. 15, 2014)

Per‐and polyfluoroalkyl substances (PFASs) including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are ubiquitous in the environment. Investigations into their fate and potential phase‐partitioning behaviour require separation of solid from aqueous phases via filtration. However, sorption of aqueous‐phase PFASs on ...

Game-Changing Technology for $350 Billion Water Treatment Industry Validated by the University of Alberta

by Biolargo, Inc.  (Oct. 21, 2014)

Scientists at the University of Alberta, Department of Agricultural, Food and Nutritional Science validated the unprecedented effectiveness of BioLargo’s (BLGO) AOS Filter in removing ...

Typing of Legionella strains isolated from environmental samples in Crete, Greece, during the period 2004–2011

by IWA Publishing  (Dec. 11, 2013)

In Greece, standard tests are performed in watering and cooling systems of hotels. A total of 1,494 water samples were collected during 2004–2011 from 124 hotels from four regions in Crete (Greece). Samples were tested for the presence of Legionella spp.; 103 isolates were identified and typed by polymerase chain reaction (PCR)-sequencing ...
