Environmental context. Secondary organic aerosol, formed by oxidation of volatile precursors such as monoterpenes, is a major contributor to the total atmospheric organic aerosol. We focus on the online mass spectrometric analysis of the aerosol generated by oxidation products of four major monoterpenes in an environmental chamber. Numerous important monoterpene oxidation products were clearly observed and provided a direct comparison of the formation of biogenic secondary organic aerosols.


Environmental context. Dissolved organic matter (DOM) plays an important role in influencing the migration and ultimate fate of metals. Different sources of pollution resulted in changes in the structure of sediment DOM in Lake Wuliangsuhai. We investigate the binding properties of DOM with CuII and HgII using fluorescence quenching combined with two-dimensional correlation spectroscopy (2D-COS) in order to demonstrate the influence of different sources of DOM on metals.

EN16144The decreasing aggregation of nanoscale zero-valent iron induced by trivalent chromium

Danlie Jiang, Xialin Hu, Rui Wang, Yujing Wang and Daqiang Yin
pp. 99-105

Environmental context. Nanoscale zero-valent iron is a promising material for environmental engineering and groundwater remediation. However, the environmental behaviour and fate of nanoscale iron that is essential for applications and risk assessment is still uncertain. We report a study on the aggregation behaviour and mobility of nanoscale iron in the aquatic environment using colloidal chemical methods.

EN16152Atmospheric short-chain-chlorinated paraffins in Melbourne, Australia – first extensive Southern Hemisphere observations

Robert W. Gillett, Ian E. Galbally, Melita D. Keywood, Jennifer C. Powell, Gavin Stevenson, Alan Yates and Anders R. Borgen
pp. 106-114

Environmental context. This study presents the first comprehensive set of ambient atmospheric concentrations of short-chain-chlorinated paraffins in the southern hemisphere. The data show a seasonal cycle with a summer maximum and a winter minimum. The seasonal cycle is consistent with temperature dependence of the vapour pressure of the short-chain-chlorinated paraffins resulting in partitioning between the atmosphere and other reservoirs with a secondary modulation by soil moisture.

EN16137On-site determination of bisphenol A in river water by a novel solid-state electrochemiluminescence quenching sensor

Xiaoying Wang, Yijie Wang, Meng Jiang, Yanqun Shan and Xiaobing Wang
pp. 115-122

Environmental context. Bisphenol A is an endocrine disruptor, which may migrate and transfer to the environment where it presents a potential risk to the health of humans and animals. Herein, we demonstrate that electrospun nanofibers could be used to develop a highly efficient solid-state quenching sensor for on-site determination of bisphenol A in river water samples. The strategy has great potential for routine environmental analyses.

EN16136Ion exchange technique (IET) to characterise Ag+ exposure in soil extracts contaminated with engineered silver nanoparticles

Dina Schwertfeger, Jessica Velicogna, Alexander Jesmer, Heather McShane, Richard Scroggins and Juliska Princz
pp. 123-133

Environmental context. Biosolid-amended soils are likely sinks for manufactured silver nanoparticles, the environmental toxicity of which is believed to be related to the release and accumulation of Ag+ ions. This study demonstrates how an ion exchange technique can be applied to soil extracts to provide Ag+ measurements at low, environmentally relevant levels. The technique is a valuable addition to existing analytical methods for tracking the behaviour of Ag nanoparticles and Ag+ ions in the terrestrial environment.

EN16202Solar-driven advanced oxidation processes for full mineralisation of azo dyes in wastewater

Chunhong Nie, Pingping Sun, Lingyue Zhu, Simeng Gao, Hongjun Wu and Baohui Wang
 

Environmental context. Full mineralisation of synthetic azo dyes in industrial wastewater is a tough job for traditional wastewater treatment technologies. There is an urgent need for the development of both sustainable and environmentally friendly technology capable of fully mineralising these azo compounds. We show that solar-driven advanced oxidation processes are capable of completely mineralising azo compounds with high utilisation of solar energy.

EN16192Doped Ti-pillared clays as effective adsorbents – Application to methylene blue and trimethoprim removal

Beatriz González, Raquel Trujillano, Miguel A. Vicente, Vicente Rives, Emerson H. de Faria, Katia J. Ciuffi, Sophia A. Korili and Antonio Gil
 

Environmental context. Water is an essential compound for life; however, several factors limit the amount available for human consumption. Every day, thousands of pollutants are discharged into drinking water. Here, new materials that are efficient as adsorbents and photocatalysts for pollutants are reported.

EN16196Boron detection and quantification based on the absorption spectra of pyridoxine and its boron complex

Fuming Chen, Ye Ai and Hui Ying Yang
 

Environmental context. Boron, an essential element for human health and the growth of animals and plants, can also be harmful when intake is excessive. Herein, a simple and efficient method for determining boron species in aqueous samples has been developed based on the optical absorption of the pyridoxine or boron–pyridoxine complex. This rapid method is suitable for online analysis, with great significance to drinking water and industrial water treatment.

EN16204In situ detection of intermediates from the interaction of dissolved sulfide and manganese oxides with a platinum electrode in aqueous systems

Yao Luo, Yougang Shen, Lihu Liu, Jun Hong, Guohong Qiu, Wenfeng Tan and Fan Liu
 

Environmental context. Dissolved sulfide results in soil acidification and subsequent contaminant leaching via oxidation processes, usually involving manganese oxides. In this work, redox processes were monitored in situ by cyclic voltammetry and HS concentrations were semi-quantitatively determined. The method provides qualitative and semi-quantitative assessment for dissolved sulfide and its oxidation intermediates in aqueous systems.


Environmental context. Dimethylsulfide is a biogeochemically important sulfur gas emitted from the oceans that can lead to aerosol formation, thereby affecting earth albedo and climate. Studies on the biogeochemistry of dimethylsulfide and its precursors and oxidation products in coastal waters can link the atmospheric chemistry of dimethylsulfide with the bioavailable organic sulfur pool in the oceans. The ensuing information is essential for understanding the biogeochemical dynamics of sulfur and its global cycles.

EN16169Mercury(II) reduction and sulfite oxidation in aqueous systems: kinetics study and speciation modeling

Kurt L. B. Solis, Go-un Nam and Yongseok Hong
 

Environmental context. Wastewater contains various substances such as sulfur-containing chemicals and heavy metals including mercury ions. Several technologies have been developed to trap mercury ions; however, mercury can undergo reactions with sulfite and change to its vapour form, which easily escapes to the atmosphere. Here, we devised a model to predict the formation of vapour-phase mercury as a function of sulfite concentration, temperature and water acidity based on coal-fired power plant wastewater.

EN16174Vanadate complexation to ferrihydrite: X-ray absorption spectroscopy and CD-MUSIC modelling

Maja A. Larsson, Ingmar Persson, Carin Sjöstedt and Jon Petter Gustafsson
 

Environmental context. Vanadium, a metal pollutant from fossil fuels and slags, may be toxic, thereby necessitating an understanding of its environmental chemistry. One important factor that controls the mobility and bioavailability of vanadium is its binding to iron oxides. This study focuses on the characterization and modelling of vanadium adsorption onto ferrihydrite. The new model can be used to simulate the transport and bioavailability of vanadium in the environment.
