A photograph of Jingang Bridge with the Tianjin Eye behind, shrouded in air pollution.

Environmental context. Atmospheric particulate NH₄⁺, primarily produced from the reaction of NH₃ and acids, is an important component of PM_2.5. In this study, nitrogen stable isotope analyses and an atmospheric chemistry model were used to estimate the contribution of major NH₃ sources to particulate NH₄⁺ in Tianjin, a megacity in North China Plain (NCP). Our research has implications for investigations of NH₃ emission sources and relevant pollution control in Tianjin and NCP. Photograph by Libin Wu.

EN24042Photolysis characteristics and influencing factors of the pesticide pyrimethanil in natural waters

Jiayun Zhao, Hui Liu

, Zhiwen Li, Xiaomei Zhu and Bing Sun

Image depicting photodegradation of pesticide in aqueous environments and graph of increasing degradation with time.

Environmental context. The widespread use of pesticides leads to a large amount of residues in natural waters where photochemical degradation is the main removal process. The factors influencing the photodegradation of pyrimethanil were investigated in different aqueous matrixes, and a chlorinated product was found in saline water, indicating a higher ecological risk of residual pyrimethanil in estuarine and nearshore water than in fresh water. A better understanding of the natural degradation mechanisms for pesticides will inform their safer use in agriculture. (Image credit: Jiayun Zhao.)

EN24031Methods and current developments of the Solvay process for brine management and CO₂ capture: a critical review

Zohreh Rahimi-Ahar

and Abbas Ghareghashi

Stylised picture of a factory releasing CO2 underneath a reactor schematic for the Solvay process.

Environmental context. This manuscript focuses on the introduction of the conventional and modified Solvay processes. The Solvay process is used to produce sodium carbonate and sodium bicarbonate, while also providing brine management and CO₂ capture. Optimal values must be used for reactant contents, temperature, salinity of the brine and stirring rate to enhance efficiency.

EN24011Quantification of palladium-labelled nanoplastics algal uptake by single cell and single particle inductively coupled plasma mass spectrometry

Elizabeth C. Bair

, Zhangzhen Guo, Tammi L. Richardson

and Jamie R. Lead

Schematic of Pd@polymer nanoplastics in solution phase and cell samples after exposure.

Environmental context. Plastic pollution is widespread and continues to be a major concern, both for the environment and human health. Identifying nanoplastics is challenging but it is important to understand how they behave once in the environment. It is shown that a combination of single particle (SP)– and single cell (SC)–inductively coupled plasma–mass spectrometry (ICP-MS) can be used to quantify nanoplastics on a per cell basis after exposure to algal cells.

EN23111Testing of the bioremediation on model substrates for complex refinery contaminants arising from accidental or deliberate facility damage

Tanja Jednak Beric

, Miroslav M. Vrvic, Marija Lješevic, Jelena Avdalovic, Mila Ilic, Dragan Crnkovic, Branimir Jovancicevic and Srdan Miletic

Environmental context. Mitigating the environmental fallout of industrial accidents is crucial. In a recent study, researchers conducted tests on model substrates to explore the effectiveness of bioremediation in treating complex refinery contaminants resulting from both accidental and deliberate facility damage. The research reveals that bioremediation can be a promising, eco-friendly solution for cleaning up such pollutants, aligning with broader efforts to combat environmental harm resulting from industrial incidents.

EN24021A critical assessment of physicochemical indices used to characterise natural dissolved organic carbon (DOC), their inter-relationships, and the effects of pH

Carolyn Morris

, Samantha Zulian, Colin J. Brauner

, Chris M. Wood

and D. Scott Smith

Diagram of samples at differing pH showing trends in colour, lipophilicity, aromaticity and charge.

Environmental context. Dissolved organic carbon (DOC) is ubiquitous in freshwater and concentrations are rising universally while pH is decreasing with climate change. This study demonstrates the interrelationships among DOC characterisation techniques and the pH-sensitive aspects of these techniques that were previously not well understood. As DOC regulates important processes within ecosystems, understanding DOC behaviour at altered pH and identifying techniques to effectively evaluate DOC composition are critical requirements for monitoring aquatic ecosystem health.

EN24024A comprehensive analysis of water-soluble arsenicals in Icelandic macroalgae

Rebecca Sim

and Ásta H. Pétursdóttir

Photograph of several seaweed species superimposed by structures of common water-soluble arsenic compounds.

Environmental context. Seaweeds are known to accumulate high levels of arsenic, and cellular concentrations may reach several orders of magnitude higher than that of the surrounding environment. Arsenic may be methylated by seaweed cells and further metabolised to water-soluble arsenic-containing sugars through unknown pathways. Whether these compounds are the result of a detoxification process or are produced with a biological purpose remains to be seen. (Image credit: Rebecca Sim.)

EN23105Developing a modern approach to assess ecological risk from pesticides without unnecessary vertebrate animal testing

David A. Dreier

, Christian Picard, Kent Kabler, Natalia Ryan, Haitian Lu, Odette Alexander-Watkins, John Abbott, Richard A. Currie

, Douglas C. Wolf

and Tharacad Ramanarayanan

Environmental context. Pesticides are critical to agriculture and food production but require ecological risk assessments. Although most risk assessments require data from vertebrate animal testing, we have developed an approach to assess risk to fish, birds and mammals using other means. This approach could help to ensure protection of the environment while minimising animal testing.

EN23117Potential for atmospheric acid processing of mineral dust to supply bioavailable trace metals to the oceans

Anthony Stockdale

and Michael D. Krom

Environmental context. Mineral dust is an important external source of trace metals to the offshore ocean. Dust exposure to acids is a significant driver of the release of dissolved trace elements. This study provides an analysis of mineral dust interaction with acid, as a proxy for atmospheric processes. An insight is given into the processes that may occur in the atmosphere where desert dust may add nutrient or toxic metals to oceans.

EN23106Characteristics, potential sources and interaction of carbonaceous components in PM_2.5 in two adjacent areas in Shanxi, China

Xiaofeng Liu

, Xin Tan, Xinyang Li, Xuan Li, Yuhuan Cheng and Kun Wang

Environmental context. Carbonaceous components in PM_2.5 have a negative effect on the environment, human health and climate. We explored the pollution characteristic, potential sources and interaction of carbonous aerosols in two adjacent areas in Shanxi, China. The concentration levels of organic carbon and elemental carbon were of a moderate level of all those measured between 2009 and 2020. Vehicle exhaust and coal combustion were the two main sources, and Yuci may be affected by the regional transport of Taiyuan in winter.

EN23108Size evolution of Eu^III–fulvic acid complexes with pH, metal, and fulvic acid concentrations: implications for modelling of metal–humic substances interactions

Yasmine Kouhail

, Pascal E. Reiller

, Laurent Vio and Marc F. Benedetti

Environmental context. This study investigates how rare earth elements (REEs), such as europium (Eu), bind to organic matter. We are also gaining valuable insights into how these elements affect the structure of the organic matter that controls their mobility in natural systems, helping us to better understand the broader processes that govern the behaviour of trace metals in the environment.

EN23116Distribution, speciation, mobility and ecological risk of potentially toxic elements in dust and PM_2.5 from abandoned mining areas

Zhaoying Shen, Hong Huang, Yujie Jiang, Yuan Tang, Changwei Zou

, Jianlong Li, Chenglong Yu and Fangxu Zhu

Environmental context. Dust is a heterogeneous material deposited on the ground surface and is a source and sink for potentially toxic elements (PTEs) originating from the air and soil. Tracking the distribution and effects of PTEs in an abandoned mining area is critical as few studies have quantified the speciation and bioavailability of PTEs contained in dust and PM_2.5. In this paper, we track the distribution of PTEs in an abandoned mining area, quantifying the mobility of PTEs using the speciation of PTEs in dust and PM_2.5 and quantitatively assess the environmental and ecological risks of PTE in a mining area.
