Release of arsenite, arsenate and methyl-arsenic species from streambed sediment affected by acid mine drainage: a microcosm study 
Marina Héry, Corinne Casiot, Eléonore Resongles, Zoe Gallice, Odile Bruneel, Angélique Desoeuvre and Sophie Delpoux

Environmental context. Arsenic-rich waters generated from the oxidation of mining wastes are responsible for the severe contamination of river waters and sediments located downstream from mining sites. Under certain environmental conditions, the affected riverbed sediments may represent a reservoir for arsenic from which this toxic element may be released into water, mainly as a consequence of microbial activity.

Investigating the photo-oxidative and heterogeneous chemical production of HCHO in the snowpack at the South Pole, Antarctica 
P. D. Hamer, D. E. Shallcross, A. Yabushita, M. Kawasaki, V. Marécal and C. S. Boxe

Snowpacks present a surprisingly active environment for photochemistry, leading to sunlight-induced oxidation of deposited organic matter and the subsequent emission of a variety of photochemically active trace gases. We seek to address questions regarding the ultimate fate of organic matter deposited onto snow in the remote regions of the world. The work is relevant to atmospheric composition and climate change.

In vitro cytotoxicity assessment of a hydraulic fracturing fluid 
Madeleine E. Payne, Heather F. Chapman, Janet Cumming and Frederic D. L. Leusch

Environmental context. Hydraulic fracturing fluids, used in large volumes by the coal seam gas mining industry, are potentially present in the environment either in underground formations or in mine wastewater (produced water). Previous studies of the human health and environmental effects of this practice have been limited because they use only desktop methods and have not considered combined mixture toxicity. We use a novel in vitro method for toxicity assessment, and describe the toxicity of a hydraulic fracturing fluid on a human gastrointestinal cell line.

A pilot interlaboratory comparison of protocols that simulate aging of nanocomposites and detect released fragments 
Wendel Wohlleben, Gemma Vilar, Elisabet Fernández-Rosas, David González-Gálvez, Claus Gabriel, Sabine Hirth, Thomas Frechen, Deborah Stanley, Justin Gorham, Li-Piin Sung, Hsiang-Chun Hsueh, Yu-Fan Chuang, Tinh Nguyen and Socorro Vazquez-Campos

Environmental context. Nanoparticles are contained in many commercialised products, but the lack of validated methods to assess their potential release into the environment hampers our ability to perform a reliable risk assessment. Equipment to simulate aging is available, but the challenge is to sample released entities, and to analyse those fragments with suitable nano-analytics. We describe methods to characterise the degradation and surface accumulation of nanoparticles, and to quantify fragments released during UV irradiation of polymer nanocomposites.

The effect of anthropogenic volatile organic compound sources on ozone in Boise, Idaho 
Victor Vargas, Marie-Cecile Chalbot, Robert O'Brien, George Nikolich, David W. Dubois, Vic Etyemezian and Ilias G. Kavouras

Environmental context. Volatile organic compounds are precursors of ozone, a pollutant with adverse environmental effects. It is important to determine the associations between the various sources of volatile organic compounds and ozone levels because emission controls are based on sources. We estimated the contributions of specific sources of volatile organic compounds on ozone levels using both measurements and statistical models, and found that traffic is the largest source even in events when wildfire smoke is present.

Solid-phase characterisation of an effective household sand filter for As, Fe and Mn removal from groundwater in Vietnam 
Andreas Voegelin, Ralf Kaegi, Michael Berg, Katja Sonja Nitzsche, Andreas Kappler, Vi Mai Lan, Pham Thi Kim Trang, Jörg Göttlicher and Ralph Steininger

Environmental context. Household sand filters are widely used in Vietnam to remove As, Fe and Mn from groundwater used as drinking water. From the solid-phase characterisation of a sand filter that has been used for 8 years, we conclude that As and Fe are retained by a combination of fast sorption reactions, surface-catalysed Fe oxidation and mediated As co-oxidation and that microbial processes are probably involved in effective Mn retention. This study contributes to a better mechanistic understanding of filter functioning as a basis for further improvements in filter design and operation.

Analysis of soil organic matter at the solid–water interface by nuclear magnetic resonance spectroscopy 
Stephanie C. Genest, Myrna J. Simpson, André J. Simpson, Ronald Soong and David J. McNally

Environmental context. Structural and conformational information on organic matter–clay complexes and whole soils was obtained using different NMR methods. The results show that organic matter interactions with clay mineral surfaces determine the accessibility of specific organic matter components at the soil–water interface. This physical conformation may also play a role in soil biogeochemical processes and binding to pollutants in terrestrial environments.

Current status and future direction for examining engineered nanoparticles in natural systems 
Manuel D. Montaño, Gregory V. Lowry, Frank von der Kammer, Julie Blue and James F. Ranville

Environmental context. The detection and characterisation of engineered nanomaterials in the environment is essential for exposure and risk assessment for this emerging class of materials. However, the ubiquitous presence of naturally occurring nanomaterials presents a unique challenge for the accurate determination of engineered nanomaterials in environmental matrices. New techniques and methodologies are being developed to overcome some of these issues by taking advantage of subtle differences in the elemental and isotopic ratios within these nanomaterials.

Separation, detection and characterisation of engineered nanoparticles in natural waters using hydrodynamic chromatography and multi-method detection (light scattering, analytical ultracentrifugation and single particle ICP-MS) 
Kim Proulx and Kevin J. Wilkinson

Environmental context. The effects of engineered nanoparticles on the environment and on human health are difficult to evaluate largely because nanoparticles are so difficult to measure. The main problems are that concentrations are low and the engineered nanoparticles are often difficult to distinguish from the environmental matrices in which they are found. We report a separation technique that facilitates the detection of engineered nanoparticles in natural waters.

In situ characterisation of physicochemical state and concentration of nanoparticles in soil ecotoxicity studies using environmental scanning electron microscopy 
Jani Tuoriniemi, Stefan Gustafsson, Eva Olsson and Martin Hassellöv

Environmental context. Characterisation of nanoparticles in terms of number concentration and aggregation state is essential for interpreting data from toxicological tests. These parameters have never been measured in situ in tests carried out in soil matrices. Here, environmental scanning electron microscopy imaging is evaluated for particles in soil, and a method for determining the number concentrations by counting the particles in the images is developed.

Recalcitrant pharmaceuticals in the aquatic environment: a comparative screening study of their occurrence, formation of phototransformation products and their in vitro toxicity 
Marlies Bergheim, Richard Gminski, Bernd Spangenberg, Malgorzata Dębiak, Alexander Bürkle, Volker Mersch-Sundermann, Klaus Kümmerer and Reto Gieré

Environmental context. Many pharmaceuticals on the market have not undergone detailed evaluation for potential aquatic toxicity. We found that most tested pharmaceuticals were persistent, that phototransformation products were likely to be formed as a result of UV treatment of wastewater and that some transformation products were more toxic to bacteria than their precursor pharmaceutical compound. Thus UV treatment of wastewater does not seem appropriate to completely degrade or transform micropollutants into harmless compounds.

Microbial fuel cells under extreme salinity: performance and microbial analysis 
Oihane Monzon, Yu Yang, Cong Yu, Qilin Li and Pedro J. J. Alvarez

Environmental context. The treatment of extremely saline, high-strength wastewaters while producing electricity represents a great opportunity to mitigate environmental effects and recover resources associated with wastes from shale oil and gas production. This paper demonstrates that extreme halophilic microbes can produce electricity at salinity up to 3- to 7-fold higher than sea water.

Observations and assessment of iron oxide and green rust nanoparticles in metal-polluted mine drainage within a steep redox gradient 
Carol A. Johnson, Gina Freyer, Maria Fabisch, Manuel A. Caraballo, Kirsten Küsel and Michael F. Hochella

Environmental context. Legacy contamination from mining operations is a serious and complex environmental problem. We examine a former uranium mine where groundwater leaving the site enters a stream with chemically dramatic effects resulting in a fundamental change in the way contaminant metals are transported to the surface environment. The results are important for our understanding of how these contaminants are dispersed, and how they could interact with the biosphere.

Aquatic toxicity of manufactured nanomaterials: challenges and recommendations for future toxicity testing 
blank image
Aaron G. Schultz , David Boyle , Danuta Chamot , Kimberly J. Ong , Kevin J. Wilkinson , James C. McGeer , Geoff Sunahara and Greg G. Goss
pp. 207-226

Environmental context. The increased use of nanomaterials in industrial and consumer products requires robust strategies to identify risks when they are released into the environment. Aquatic toxicologists are beginning to possess a clearer understanding of the chemical and physical properties of nanomaterials in solution, and which of the properties potentially affect the health of aquatic organisms. This review highlights the main challenges encountered in aquatic nanotoxicity testing, provides recommendations for overcoming these challenges, and discusses recent studies that have advanced our understanding of the toxicity of three important OECD nanomaterials, titanium dioxide, zinc oxide and silver nanomaterials.

pp. 227-246

Environmental context. The ability of the soil nematode Caenorhabditis elegans to withstand a wide range of environmental conditions makes it an idea model for studying the bioavailability and effects of engineered nanomaterials. We critically review what has been learned about the environmental fate of engineered nanoparticles, their effects and their mechanisms of toxicity using this model organism. Future systematic manipulation of nanoparticle properties and environmental variables should elucidate how their interaction influences toxicity and increase the predictive power of nanomaterial toxicity studies.

Isotopically modified silver nanoparticles to assess nanosilver bioavailability and toxicity at environmentally relevant exposures 
blank image
Marie-Noële Croteau , Agnieszka D. Dybowska , Samuel N. Luoma , Superb K. Misra and Eugenia Valsami-Jones
pp. 247-256

Environmental context. Predicting the environmental implications of nanotechnology is complex in part because of the difficulty in studying nanoparticle uptake in organisms at environmentally realistic exposures. Typically, high exposure concentrations are needed to detect accumulation and effects. We use labelled Ag nanoparticles to determine whether Ag bioaccumulation responses are linear over concentrations likely to occur in the environment, and whether concentration-dependent changes in agglomeration and dissolution affect bioavailability.

Nanoparticle core properties affect attachment of macromolecule-coated nanoparticles to silica surfaces 
blank image
Ernest M. Hotze , Stacey M. Louie , Shihong Lin , Mark R. Wiesner and Gregory V. Lowry
pp. 257-267

Environmental context. The increasing use of engineered nanoparticles has led to concerns over potential exposure to these novel materials. Predictions of nanoparticle transport in the environment and exposure risks could be simplified if all nanoparticles showed similar deposition behaviour when coated with macromolecules used in production or encountered in the environment. We show, however, that each nanoparticle in this study exhibited distinct deposition behaviour even when coated, and hence risk assessments may need to be specifically tailored to each type of nanoparticle.

Toxicity of cerium oxide nanoparticles to the earthworm Eisenia fetida: subtle effects 
blank image
Elma Lahive , Kerstin Jurkschat , Benjamin J. Shaw , Richard D. Handy , David J. Spurgeon and Claus Svendsen
pp. 268-278

Environmental context. This study investigates the toxicity of cerium oxide nanoparticles to earthworms, key organisms in soil ecosystems. Cerium oxide did not affect survival or reproduction of the earthworms but did exert histological changes. We conclude that current soil guidelines, based simply on metal toxicity, appear to adequately protect against cerium exposure risk, at least for earthworms.

Mario Villalobos , Manuel Carrillo-Cárdenas , Richard Gibson , N. Ruth López-Santiago and Jimmy A. Morales
pp. 279-288

Environmental context. Sorption and oxidation reactions at mineral surfaces can substantially influence the mobility and toxicity of environmental contaminants. An understanding of the factors that control these reactions is crucial for predicting the fate of contaminant species. We investigate the reactivity of manganese oxides towards polycyclic aromatic hydrocarbons, persistent organic compounds of environmental concern.

The degradation of arsenoribosides from Ecklonia radiata tissues decomposed in natural and microbially manipulated microcosms 
blank image
Elliott G. Duncan , William A. Maher , Simon D. Foster , Frank Krikowa and Katarina M. Mikac
pp. 289-300

Environmental context. Arsenoribosides are the major arsenic species in marine macro-algae, yet inorganic arsenic is the major arsenic species found in seawater. We investigated the degradation of arsenoribosides associated with Ecklonia radiata by the use of microcosms containing both natural and autoclaved seawater and sand. The decomposition and persistence of arsenic species was linked to the use of autoclaved seawater and sand, which suggests that arsenoriboside degradation is governed by the microbial composition of microenvironments within marine systems.

Composites of nanostructured calcium silicate hydrate with superparamagnetic particles and their use in the uptake of copper from solution 
blank image
Mathew J. Cairns , Giancarlo M. Barassi and Thomas Borrmann
pp. 301-308

Environmental context. Mining operations release dissolved metals in waste streams which can present an environmental hazard as well as an economic loss. Large volumes of waste water and low levels of metals mean that highly effective materials such as nanoparticles or nanostructures need to be employed to remove the dissolved metals from the stream. The challenge in using nanotechnology lies in the recovery of the particles, as filtration proves ineffective; this article discusses use of magnetic composites as a potential solution to this challenge.

Development and validation of a shipboard system for measuring high-resolution vertical profiles of aqueous dimethylsulfide concentrations using chemical ionisation mass spectrometry 
blank image
Sarah-Jeanne Royer , Martí Galí , Eric S. Saltzman , Cyril A. McCormick , Thomas G. Bell and Rafel Simó
pp. 309-317

Environmental context. Dimethylsulfide, a trace gas produced by oceanic plankton, is a key chemical species in the global cycles of sulfur and aerosols, with implications that span marine ecology to climate regulation. Knowledge of what governs dimethylsulfide production in the surface ocean depends on our ability to measure concentration changes over time and depth. We describe a sampling and analytical system that provides continuous shipboard measurements of dimethylsulfide concentrations in high-resolution vertical profiles.

Modelling proton and metal binding to humic substances with the NICA–EPN model 
blank image
Andrea C. Montenegro , Silvia Orsetti and Fernando V. Molina
pp. 318-332

Environmental context. The toxicity of metals in the environment is greatly influenced by natural organic matter owing to its ability to bind metals to form complexes that can be immobile and non-bioavailable. Sound mathematical models are important to reliably predict the behaviour of such contaminants, and how they are affected by organic matter and other environmental colloids. Here a new model is discussed and compared with precedent ones.

pp. 333-340

Environmental context. Photolysis is one of the most important transformation pathways in natural ecosystem for enrofloxacin (Enro), which is a hazard for humans and other living organisms. The effects of NO3 and humic acid on Enro photolysis were found to be light-source dependent. These results are of significance toward the goal of providing insight into the transformation and fate of Enro in the environment.

pp. 341-350

Environmental context. Recently developed fast fluorescence detectors have opened the way to the development of element speciation mapping, i.e. X-ray absorption near edge spectroscopy (XANES) imaging, of environmental samples. This technique is potentially very informative but is also highly data intensive. Here, we used XANES imaging to explore the distribution of Cu species in biosolid materials, destined for agricultural use, as this is of importance in relation to the bioavailability and potential toxicity of this metal.
