EN24024A comprehensive analysis of water-soluble arsenicals in Icelandic macroalgae

Rebecca Sim 0000-0001-7398-8062 and Ásta H. Pétursdóttir 0000-0002-6739-0598

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 0000-0002-2669-7358, Christian Picard, Kent Kabler, Natalia Ryan, Haitian Lu, Odette Alexander-Watkins, John Abbott, Richard A. Currie 0000-0002-6528-3326, Douglas C. Wolf 0000-0003-1868-9574 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 0000-0002-1603-0103 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 PM2.5 in two adjacent areas in Shanxi, China

Xiaofeng Liu 0000-0002-6019-4965, Xin Tan, Xinyang Li, Xuan Li, Yuhuan Cheng and Kun Wang
 

Environmental context. Carbonaceous components in PM2.5 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 EuIII–fulvic acid complexes with pH, metal, and fulvic acid concentrations: implications for modelling of metal–humic substances interactions

Yasmine Kouhail 0000-0003-4371-5690, Pascal E. Reiller 0000-0002-7317-359X, Laurent Vio and Marc F. Benedetti 0000-0003-1075-8205
 

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 PM2.5 from abandoned mining areas

Zhaoying Shen, Hong Huang, Yujie Jiang, Yuan Tang, Changwei Zou 0000-0002-9760-3486, 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 PM2.5. 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 PM2.5 and quantitatively assess the environmental and ecological risks of PTE in a mining area.

EN23093Natural cobalt–manganese oxide nanoparticles: speciation, detection and implications for cobalt cycling

Environmental context.  Cobalt is a technologically critical element due to its uses in the green energy transition, but its cycling is poorly constrained in surface environments. We determined the form of cobalt in naturally enriched soils and found that it is commonly associated with manganese as mixed oxide nanoparticles. These findings demonstrate that the behaviour of critical elements such as cobalt in the environment is in part governed at the nanoscale. (Photograph by O. P. Missen, 11 July 2022.)

EN23114Effects of arsenite and dimethylarsenic on the growth and health of hydroponically grown commercial Doongara rice

Hayden P. Martin, William A. Maher 0000-0001-7564-3383, Peter Snell, Kim J. Philpot and Michael J. Ellwood 0000-0003-4288-8530
 

Environmental context. Arsenic’s effect on rice plant health is a critical environmental issue. This study reveals that rice plants absorb inorganic arsenic and dimethylarsenic differently, with dimethylarsenic posing a greater threat to rice plant health. These findings contribute to our understanding of arsenic toxicity in plants, highlighting the need for further research into detoxification strategies for dimethylarsenic.

Environmental context. Mine tailings are a mixture of fine materials obtained after crushing, processing and extracting the valuable minerals from ore. Ultramafic and mafic mine tailings have the potential to mineralise carbon, offering a solution to offset greenhouse gas emissions from the mining sector. The study revealed that the effects of wetting and drying ultramafic and mafic mine tailings under atmospheric conditions have the potential for carbon sequestration and acid mine drainage.

EN23112Occurrence, spatial distribution, risk assessment, and management of environmental estrogens in surface waters of the Taihu basin

Environmental context. Environmental estrogens can disrupt the normal functioning of endocrine systems, and their occurrence in drinking water sources could cause potential health risk. We investigated concentrations of four estrogens in the lakes from the Taihu Basin, and found that BPA and EE2 were elevated in some sites. However, concentrations of all four environmental estrogens were below the national standards, and caused no health threat to local population.

Environmental context. Wildland fire smoke and its impacts on air quality and human health are increasing globally. However, uncertainties in organic emissions from these fires hinder our understanding of downwind atmospheric photochemical processes driving the formation of hazardous air pollutants. In this study, we investigated the impact of fuel moisture content on organic species emission during the combustion of ponderosa pine needles, an important fuel source in the western United States.

Environmental context. Arsenic (As) contamination in agricultural soil threatens safe agricultural production. Therefore, an ex situ magnet-assisted soil washing, using different types of nanoscale zerovalent iron was tested as a remediation option in soil restoration. Uncoated nanoparticles was the best tested option, with As removal at 45.5% and the nanoparticles were reusable up to four times.

EN23077Photolysis characteristics and influencing factors of adenosine 5′-monophosphate in seawater

Xiao-Yan Cao 0000-0002-4382-8321, Min Liu, Ling Li and Gui-Peng Yang 0000-0002-0107-4568
 

Environmental context Organophosphorus (OP) is bioavailable to phytoplankton with photolysis can play an important role in the process. The photolysis behaviour of an OP (adenosine 5′-monophosphate, AMP) in seawater was investigated, and AMP can release inorganic phosphate under environmentally relevant light conditions, indicating OP photodegradation might be important in the phosphorus biogeochemical cycle. The results are helpful to further understand the bioavailability and cycle of OP in marine environment.
