Iron(III)-induced activation of chloride from artificial sea-salt aerosol 
Julian Wittmer, Sergej Bleicher, Johannes Ofner and Cornelius Zetzsch

Environmental context. Inorganic, natural aerosols (sea-salt, mineral dust, glacial flour) and contributions of anthropogenic components (fly ash, dust from steel production and processing, etc.) contain iron that can be dissolved as FeIII in saline media. This study investigates photochemical processes in clouds and aerosols producing gas-phase Cl as a function of salt- and gas-phase composition employing a simulation chamber. Atomic Cl may contribute to the oxidative capacity of the troposphere, and our findings imply local sources.

Seasonal changes in chlorine and methoxyl content of leaves of deciduous trees and their impact on release of chloromethane and methanol at elevated temperatures 
W. Colin McRoberts, Frank Keppler, David B. Harper and John T. G. Hamilton

Environmental context. Chloromethane is the most abundant naturally produced chlorine-containing organic compound, responsible for ~16 % of chlorine-catalysed stratospheric ozone destruction. A significant source of this gas is emission from biomass by reaction between chloride ion and methoxyl groups of the biopolymers pectin and lignin. The seasonal changes in the chlorine and methoxyl pools observed in leaves of several deciduous tree species have implications for understanding chlorine volatilisation during biomass burning and estimation of the global chloromethane budget.

Thermolytic degradation of methylmethionine and implications for its role in DMS and MeCl formation in hypersaline environments 
Ines Mulder, Torsten Krause, Tobias Sattler, Christoph Tubbesing, Sabine Studenroth, Krzysztof Bukowski, Elliot Atlas and Heinz F. Schöler

Environmental context. Methyl chloride and dimethyl sulfide are important atmospheric trace gases, but their biogeochemical contributions to the atmosphere are not fully understood. The amino acid derivative methyl methionine has been hypothesised to be a precursor of these two atmospheric gases, especially in drying salt-lake environments. We found methyl chloride and dimethyl sulfide in salt crystals and soils samples of hypersaline lakes, suggesting that a thermal decay of methyl methionine could be one of the formation mechanisms responsible.

New particle formation above a simulated salt lake in aerosol chamber experiments 
K. A. Kamilli, J. Ofner, B. Lendl, P. Schmitt-Kopplin and A. Held

Environmental context. Deforestation in Western Australia beginning in the mid-19th century led to a considerable change of the land surface, and Western Australia is now suffering more often from droughts. Particle formation induced by salt lakes has been identified as a potential control factor for changed precipitation patterns. This study aims to determine key factors involved in the particle formation process by simulating a simplified salt lake in an aerosol chamber in the laboratory.

Vertical distribution of BrO in the boundary layer at the Dead Sea 
Robert Holla, Stefan Schmitt, Udo Frieß, Denis Pöhler, Jutta Zingler, Ulrich Corsmeier and Ulrich Platt

Environmental context. Reactive halogen species affect chemical processes in the troposphere in many ways. The reactive bromine species bromine monoxide (BrO) is found in high concentrations at the Dead Sea, but processes for its formation and its spatial distribution are largely unknown. Information on the vertical distribution of BrO at the Dead Sea obtained in this work may give insight into the processes leading to BrO release and its consequences.

Iron-catalysed oxidation and halogenation of organic matter in nature 
Peter Comba, Marion Kerscher, Torsten Krause and Heinz Friedrich Schöler

Environmental context. Natural organohalogens produced in and released from soils are of utmost importance for ozone depletion in the stratosphere. Formation mechanisms of natural organohalogens are reviewed with particular attention to recent advances in biomimetic chemistry as well as in radical-based Fenton chemistry. Iron-catalysed oxidation in biotic and abiotic systems converts organic matter in nature to organohalogens.

Dynamics of halocarbons in coastal surface waters during short term mesocosm experiments 
Anna Orlikowska, Christian Stolle, Falk Pollehne, Klaus Jürgens and Detlef E. Schulz-Bull

Environmental context. Halocarbons are trace gases important in atmospheric ozone chemistry whose biogenic production – among other factors – depends on light-induced stress of marine algae. Several studies have confirmed this effect in laboratory experiments but knowledge in natural systems remains sparse. In mesocosm experiments, which are a link between field and laboratory studies, we observed that the influence of natural levels of ultraviolet radiation on halocarbon dynamics in the marine surface waters was either insignificant or concealed by the complex interactions in the natural systems.

Halogenated hydrocarbon formation in a moderately acidic salt lake in Western Australia – role of abiotic and biotic processes 
A. Ruecker, P. Weigold, S. Behrens, M. Jochmann, X. L. Osorio Barajas and A. Kappler

Environmental context. Volatile halogenated organic compounds (VOX) contribute to ozone depletion and global warming. Here we demonstrate that acidic salt lake sediments in Western Australia contribute to the global natural emission of these compounds and that the emissions are primarily of biotic origin. Elucidating major sources and sinks of VOX is a key task in environmental chemistry because their formation and degradation have major effects on atmospheric chemistry and thus earth climate.

Dissolution of mixed amorphous–crystalline Cd-containing Fe coprecipitates in the presence of common organic ligands 
Carla E. Rosenfeld and Carmen E. Martínez

Environmental context. Common soil minerals, which often contain trace metals in contaminated environments, are thought to limit metal-related risks in the environment. We studied the stability of these contaminated minerals and found that the presence of plant-derived organic compounds can alter contaminant availability in such environments. Understanding how soluble organics may change trace metal availability helps to predict risk and potentially remediate such environments more efficiently.

A recent survey of naturally occurring organohalogen compounds 
Gordon W. Gribble

Environmental context. The general perception that nature does not produce compounds containing halogens – chlorine, bromine, iodine and fluorine – is now known to be erroneous. Modern isolation and identification techniques have led to the discovery of more than 5000 halogen-containing compounds from myriad marine and terrestrial plant and animal sources. Many of these compounds possess extraordinary biological activity, including anticancer, antiviral and antibacterial activity of potential human benefit.

Interaction of humic acids with soil minerals: adsorption and surface aggregation induced by Ca2+ 
Nanci Kloster and Marcelo Avena

Environmental context. Humic acids, important components of natural organic matter in soils, sediments and aquatic media, can interact with the surface of minerals affecting key environmental processes. In the presence of calcium, humic acids can also interact among themselves leading to molecular aggregates. We demonstrate that a solid mineral surface facilitates the formation of humic acid aggregates, and thus surface aggregation occurs under conditions where normal aggregation in solution does not occur.

Change in chirality of semiconducting single-walled carbon nanotubes can overcome anionic surfactant stabilisation: a systematic study of aggregation kinetics 
Iftheker A. Khan, Joseph R. V. Flora, A. R. M. Nabiul Afrooz, Nirupam Aich, P. Ariette Schierz, P. Lee Ferguson, Tara Sabo-Attwood and Navid B. Saleh

Environmental context. Chirally enriched semiconducting single-walled carbon nanotubes (SWNTs) are some of the most utilised nanomaterials. Although chirality of SWNTs is known to influence their electronic properties and interfacial interaction, the interplay between chirality and surfactant structure in SWNT stability is not well understood. This study investigates these interactions, providing data to better assess the environmental fate of SWNTs.

Effect of fluctuating oxygen concentration on iron oxidation at the pelagic ferrocline of a meromictic lake 
Jenny Bravidor, Julika Kreling, Andreas Lorke and Matthias Koschorreck

Environmental context. The cycling of iron plays an important role in pelagic boundary zones such as the oxic–anoxic interface where physical and chemical gradients occur. The turnover of iron in this zone depends on oxygen fluctuation and the duration of the fluctuation event. This study increases the understanding of biogeochemical iron transformation in such hotspots.

Adsorption of trace metals by microplastic pellets in fresh water 
Andrew Turner and Luke A. Holmes

Environmental context. Although microplastics are known to adsorb and transport contaminants in the aquatic environment, there is no information on the significance of the effect in fresh waters. We studied the adsorption of metals to new and aged plastic pellets in river water, and show interactions that are dependent on time, pH and metal concentration. Because metals have a higher affinity for aged pellets than for new pellets, weathered microplastics could represent a significant vehicle for the transport of metals in aquatic environments.

Current perspective on produced water management challenges during hydraulic fracturing for oil and gas recovery 
blank image
Kelvin Gregory and Arvind Murali Mohan
pp. 261-266

Environmental context. There is growing worldwide interest in the production of oil and gas from deep, shale formations following advances in the technical expertise to exploit these resources such as hydraulic fracturing (fracking). The potential widespread application of hydraulic fracturing has raised concerns over deleterious environmental impacts on fragile water resources. We discuss the environmental management challenges faced by the oil and gas industry, and the opportunities for innovation in the industry.

Chemical and bioanalytical assessment of coal seam gas associated water 
blank image
Janet Y. M. Tang, Mauricio Taulis, Jacinta Edebeli, Frederic D. L. Leusch, Paul Jagals, Gregory P. Jackson and Beate I. Escher
pp. 267-285

Environmental context. Water associated with coal seam gas is generally of poor quality and thus its management and potential further usage is a subject of concern. In a comprehensive study involving chemical and bioanalytical assessments of coal seam gas associated water, we found that less than 5 % of the biological effects could be explained by chemical analysis. The use of bioanalytical tools to complement chemical analysis is recommended for monitoring the quality of water associated with coal seam gas.

In vitro cytotoxicity assessment of a hydraulic fracturing fluid 
blank image
Madeleine E. Payne, Heather F. Chapman, Janet Cumming and Frederic D. L. Leusch
pp. 286-292

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.

Oihane Monzon, Yu Yang, Cong Yu, Qilin Li and Pedro J. J. Alvarez
pp. 293-299

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.

Lawton Shaw, Chuyen Phung and Michael Grace
pp. 301-306

Environmental context. Pharmaceuticals and personal care products are routinely found in waters discharged from treatment plants and in surrounding aquatic ecosystems. Despite the widespread occurrence of these biologically active agents, there is limited understanding of their potential effects on key ecosystem processes such as primary production, ecosystem respiration and algal growth. This paper examines the effects of five common pharmaceuticals on the rates of these fundamental processes.

Corinne Parat, Laurent Authier, Alain Castetbon, David Aguilar, Encarna Companys, Jaume Puy, Josep Galceran and Martine Potin-Gautier
pp. 329-337

Environmental context. Knowledge of the speciation of metals, especially of the free metal ion concentration, is essential to understand the fate of these elements in rivers and their effects on living organisms. On-site analyses are preferred for these measurements as they allow problems associated with sample transportation and preservation to be avoided. In this context, an on-site methodology based on an electrochemical method and screen-printed sensors has been developed in the laboratory and validated on site.

Catherine Guigue, Lionel Bigot, Jean Turquet, Marc Tedetti, Nicolas Ferretto, Madeleine Goutx and Pascale Cuet
pp. 350-365

Environmental context. Hydrocarbons are among the most widespread and harmful pollutants found in the aquatic media. Although they have been investigated in various temperate coastal environments, their dynamics in coral reef tropical ecosystems, which are under increasing human pressure, remain poorly understood. It was found that hydrocarbons had moderate to high concentrations, multiple origins (biogenic and anthropogenic) and could be used to track inland intrusions in fore reef waters of the eutrophicated La Saline reef ecosystem (La Réunion Island, Indian Ocean).

pp. 366-373

Environmental context. Methoxylated and hydroxylated polybrominated diphenyl ethers are of increasing concern owing to their global distribution and potential ecological risks. We investigated the spatial distribution and sources of these brominated compounds in surface sediments from the southern Yellow Sea, China. The results suggest that marine phytoplankton may be the potential producers of these compounds, thereby providing new insights into their occurrence and provenance in marine environments.
