Two pie charts detailing pollution sources for Chengguan (left) and Xigu (right) districts.

Environmental context. Exploring the characterisation and sources of the chemical composition of fine particulate matter in the atmosphere is critical to human health. Dust, primarily from soil, is the main source of atmospheric fine particulate matter in Chengguan and Xigu Districts of Lanzhou City, Gansu Province, rather than other causes. This provides directions and ideas for future local ecological environment and pollution management. (Image credit: Qin Cui.)

EN23131Daphnia reproductive impacts following chronic exposure to micro- and nano-scale particles from three types of rubber

Brittany E. Cunningham 0000-0002-2164-9402, Bryan J. Harper, Susanne M. Brander and Stacey L. Harper
 

Schematic showing the testing of Daphnia with different types of rubber.

Environmental context. Tyre rubber particles, from both driving and reuse of tyre rubber, are pollutants that carry toxic chemicals into the environment. We investigated the long-term effects that these particles have on small aquatic organisms and found that they drastically reduce their ability to reproduce. Continued exposure of aquatic invertebrates to tyre-related pollutants, has the potential to affect the population by inhibiting reproduction into future generations.

EN24062Influence of initial speciation of platinum and palladium on their accumulation and toxicity towards phytoplankton

Julien Michaud-Valcourt 0009-0002-8136-0480, Sylvie Blanc, Louis Courtois, Jelle Mertens, Séverine Le Faucheur and Claude Fortin 0000-0002-2479-1869
 

Diagram indicating the determined toxicity of the Pd and Pt complexes studied towards phytoplankton.

Environmental context. The increasing global demand for platinum and palladium for the development of new technologies will likely enhance their biogeochemical mobility. However, our understanding of the environmental risks of these metals remains incomplete. To help fill this knowledge gap, we determined the toxicity of various forms of platinum and palladium on a green alga. We found that palladium was more toxic than platinum and that platinum toxicity depended on the form tested. (Image credit: J. Michaud-Valcourt.)

Environmental context. Atmospheric particulate NH4+, primarily produced from the reaction of NH3 and acids, is an important component of PM2.5. 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 0000-0001-8991-9192, 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.)

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

Elizabeth C. Bair 0000-0001-7277-8688, Zhangzhen Guo, Tammi L. Richardson 0000-0002-0667-3455 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.

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.

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.)

Collections

Collections are a curation of articles relevant to a topical research area

Mercury in the environment

Mercury is a ubiquitous environmental contaminant. In Australia, there is an active Mercury Australia Network that held a symposium in 2023 that demonstrated the interest in the topic. We are seeking papers that cover all aspects of mercury in the environment, not only in Australia but in other international locations.

Environmental Chemistry publishes manuscripts addressing the chemistry of the natural and engineered environment (including indoor and outdoor air, water, earth and biota), including the behaviour and impacts of contaminants and other anthropogenic disturbances. The scope encompasses atmospheric chemistry, geochemistry and biogeochemistry, climate change, marine and freshwater chemistry, polar chemistry, fire chemistry, soil and sediment chemistry, and chemical aspects of ecotoxicology. Papers that take an interdisciplinary approach, while advancing our understanding of the linkages between chemistry and physical or biological processes, are particularly encouraged. The special issue will consider all studies that cover any of these areas in relation to mercury as an environmental contaminant.
