Development of a recombinant human ovarian (BG1) cell line containing estrogen receptor α and β for improved detection of estrogenic/antiestrogenic chemicals

by John Wiley & Sons, Ltd.  (Jul. 3, 2015)

Estrogenic endocrine disrupting chemicals are found in environmental and biological samples, commercial and consumer products, food, and numerous other sources. Given their ubiquitous nature and potential for adverse effects, there is a critical need for rapidly detecting these chemicals. We developed an estrogen‐responsive recombinant human ...

Responses of Hyalella azteca to acute and chronic microplastic

by John Wiley & Sons, Ltd.  (Jun. 4, 2015)

Limited information is available on the presence of microplastics (MPs) in freshwater systems, and even less about the toxicological implications of the exposure of aquatic organisms to plastic particles. The present study was conducted to evaluate the effects of MP ingestion on the freshwater amphipod, Hyalella azteca. H. azteca was exposed to ...

Tracking multiple modes of endocrine activity in Australia's largest inland sewage treatment plant and effluent‐receiving environment using a panel of in vitro bioassays

by John Wiley & Sons, Ltd.  (May 2, 2015)

Estrogenicity of sewage effluents, and related ecotoxicological effects in effluent‐receiving environments, has been widely reported over the last two decades. However, relatively little attention has been given to other endocrine pathways that may be similarly disrupted by a growing list of ‘contaminants of concern’. Further, the Australian ...

A robust bioassay to assess the toxicity of metals to the antarctic marine microalga Phaeocystis antarctica

by John Wiley & Sons, Ltd.  (Apr. 30, 2015)

Despite evidence of contamination in Antarctic coastal marine environments, no water‐quality guidelines have been established for the region because of a paucity of biological effects data for local Antarctic species. Currently, there is limited information on the sensitivity of Antarctic microalgae to metal contamination, which is exacerbated ...

Linking trace element variations with macronutrients and major cations in marine mussels Mytilus edulis and Perna viridis

by John Wiley & Sons, Ltd.  (Apr. 21, 2015)

Marine mussels have long been used as biomonitors of contamination of trace elements, but little is known whether variation in tissue trace elements is significantly associated with those of macronutrients and major cations. Here, we examined the variability of macronutrients and major cations and their potential relationships with ...

Detection of polycyclic aromatic hydrocarbons (PAHs) in raw menhaden fish oil using fluorescence spectroscopy: Method development

by John Wiley & Sons, Ltd.  (Apr. 13, 2015)

Raw menhaden fish oil was developed for biomonitoring polycyclic aromatic hydrocarbons (PAHs) using fluorescence spectroscopy. Menhaden (Genus Brevoortia) were collected from Delaware Bay, NJ (DBNJ), James River, VA, Vermillion Bay, LA (VBLA) and Barataria Bay, LA (BBLA) in 2010 and/or 2011. Barataria Bay, LA received heavy oiling from the ...

Improved sensitivity to heavy metals in the bioluminescence assay using alternative salt solutions

by microLAN On-line Biomonitoring Systems  (Apr. 1, 2015)

Introduction The marine bacterium Vibrio fischeri is widely used for the toxicity assessment of environmental samples. The toxicity is measured in a medium containing 2% NaCl. When the bacteria are exposed to toxic compounds, the light production is inhibited. Toxicity values are obtained after 15 and 30 minutes exposure and expressed as EC50 ...

Microbial fuel cell-based biosensors for environmental monitoring: a review

by IWA Publishing  (Mar. 27, 2015)

The microbial fuel cell (MFC) is an innovative technology that was initially designed to harness energy from organic waste using microorganisms. It is striking how many promising applications beyond energy production have been explored in recent decades. In particular, MFC-based biosensors are considered to be the next generation biosensing ...

Evaluation of acute ecotoxicity removal from industrial wastewater using a battery of rapid bioassays

by IWA Publishing  (Dec. 19, 2014)

The present study compares conventional wastewater treatment technologies (coagulation–flocculation and activated sludge) and powdered activated carbon (PAC) treatment for the removal of acute ecotoxicity from wastewater generated by tank truck cleaning (TTC) processes. Ecotoxicity was assessed with a battery of four commercially ...

Zebra mussels (Dreissena polymorpha) as a biomonitor of trace elements along the southern shoreline of lake michigan

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

The invasive zebra mussel (Dreissena polymorpha) has become an accepted biomonitor organism for trace elements, but it has yet to be studied along the Lake Michigan shoreline. Likewise, the relationships between tissue concentrations of elements, organism size and sediment concentrations of elements have not been fully explained. This study ...
