EN24101Research on the effect of dissolved organic matter on the adsorption of oxytetracycline by high-density polyethylene

Qitian Xiao, Hui Liu 0009-0003-7128-8718, Jiying Zou, Haonan He, Jia Wei and Zhesheng Hou
 

FT-IR spectra of HDPE and HDPE bound to fulvic acid and oxytetracycline.

Environmental context. In the soil environment, microplastics (HDPE) act as carriers to adsorb contaminants, interacting with dissolved organic matter (DOM) and antibiotics such as oxytetracycline (OTC). The results show that DOM plays a bridging role in the HDPE–OTC adsorption system, and its hydrophobic groups are complexed with OTC, resulting in the quenching of DOM ultraviolet spectrum.

Environmental context. Polybrominated diphenyl ethers (PBDEs) are compounds that have previously been widely applied in many consumer and commercial products; their use is banned because of their toxicity but they remain a legacy environmental pollutant. This study provides concentrations of PBDEs in indoor and outdoor dust and soils. Relationships between their occurrence patterns and origins are established, which informs our understanding of threats to human health from soil and air exposure. (Image credit: the authors.)

EN24103Mercury concentration in Antarctic krill varies in time and space and with individual size

Rita M. Franco-Santos 0000-0001-7846-3425, Sam Eggins, Michael J. Ellwood, Nils Hoem, Peter D. Nichols, Patti Virtue and William A. Maher 0000-0001-7564-3383
 

Illustration of the sampling locations, sample processing steps and seasonal variation in krill mercury concentrations.

Environmental context. Several predators that eat Antarctic krill may be unintentionally ingesting toxic substances. Studying aspects of krill life to understand the effects of potential increases in Antarctic mercury (Hg) availability revealed that seasons, locations and individual size influence krill Hg concentration. Despite increasing human presence (potential Hg sources) in Antarctica, krill Hg content remains stable, and evidence suggests that Hg accumulates in predators by both short (krill-based) and longer food chains.

EN23031Historical (1850–1995) nitrogen changes in UK catchments recorded by lake sediment δ15N

Simon David Turner 0000-0001-8692-8210, Neil Rose 0000-0002-5697-7334, John Boyle, Gavin Simpson and Elizabeth Gardner
 

Environmental context. Unprecedented modification of the global nitrogen cycle by human activity is strongly imprinted in UK lakes by the changing abundance of nitrogen isotopes found in layers of lake sediment. UK lakes in the last century have responded to this change depending on their location, particularly if they are remote and occur above ~300-m altitude. Historical sediment nitrogen isotope data illustrate the impact of variable N sources on UK lakes, from fossil fuel combustion, synthetic fertilisers, to land use change and wastewater.

EN24098Precipitation Isotopes New Zealand (PINZ): improvements in precipitation isoscapes with machine learning

A. F. Hill 0000-0003-4089-5147, A. McKenzie, B. D. Dudley and D. B. Nelson
 

Representative monthly precipitation isoscape for New Zealand (δ18O for October 2023 shown).

Environmental context. Stable water isotopes δ18O and δ2H in atmospheric precipitation are valuable hydrologic tracers with varied applications, but measuring them over large scales is impractical. Precipitation isotope models (isoscapes) are instead needed to predict isotopes through space and time. Precipitation isotopes are affected by numerous variables ranging from orographic effects to phase changes to moisture mass origin, making them challenging to predict in complex geographies such as New Zealand. Improving data density together with recent advances in modelling approaches hold promise for improving accuracy of precipitation isoscapes in New Zealand and similar locations.

EN24054Aqueous lead speciation determined using DNAzyme GR5

Gaganprit K. Gill, Juewen Liu, Heather M. Gaebler, Ian Hamilton and D. Scott Smith 0000-0002-3075-4087
 

Schematic representation of the Pb species induced cleavage reaction of DNAzyme GR5.

Environmental context. The on-site and real-time detection of metal ions is important for environmental monitoring and risk assessment. For appropriate management decisions, it is necessary to specifically sense the labile fraction of metal rather than total metal. This study provides a proof-of-principle that the DNAzyme GR5 can be used to sense labile lead in natural waters containing dissolved organic matter. (Image credit: D. Scott Smith.)

EN24083Bioindicators for monitoring atmospheric perfluorinated compounds: review of occurrences, transport, fate and analytical protocols

Nnanake-Abasi O. Offiong 0000-0003-4692-7891, Imeh J. Okop, Solomon E. Shaibu, Edidiong S. Akwaowo, Akwaowo I. Inyangudoh, Nnamso D. Ibuotenang, Idongesit A. Victor, George A. Robert, Timilehin A. Adegboyega and Nsikak U. Benson
 

Environmental context: Perfluorinated compounds are emerging organic contaminants recently detected in various environmental matrices and remain largely unregulated. Among these matrices, air is the least studied one due to analytical challenges. This review explores emerging trends in analysing perfluorinated compounds in air with the use of bioindicators and highlights future research needs to address existing gaps in detection and monitoring.

EN24093Altitudinal variations and local emission contributions to black carbon and ion deposition on Tibetan Plateau glaciers

Yixi Liu 0009-0009-0508-8199, Chao Zhang, Fangping Yan, Pengling Wang and Chaoliu Li
 

Pictorial representation of the glaciers studied and their proximity and routes of exposure to pollutants.

Environmental context. Impurities deposited on glaciers can significantly accelerate their melting. This study investigated the spatial variability of concentrations of impurities across three glaciers on the Tibetan Plateau, revealing a pronounced concentration increase with decreasing altitude and the influence of local emissions. To accurately evaluate the potential for glacier melt, it is necessary to account for local emissions and altitude-dependent variations of impurities in individual glaciers. (Image credit: Yixi Liu)

EN24041Solubility and dissolution kinetics of particle-bound metals in a surrogate lung fluid

Sara D’Aronco, Valerio Di Marco, Alberto Gambalunga, Federica Chiara, Andrea Trevisan and Chiara Giorio 0000-0001-7821-7398
 

An illustration of aerosol transportation from the environment into the epithelial lining fluid where it can be partly solubilised.

Environmental context. Metals in airborne particles can interact with lung fluids once particles are inhaled. Water solubility of particle-bound metals is often used to define their bioavailability. We show that particle-bound metals exhibit a complex dissolution kinetics in a surrogate lung fluid, their solubility and dissolution kinetics are driven by the fluid composition, and only to a minor extent by atmospheric aqueous phase processing of aerosols.

EN24088Mercury patterns in lakes within a natural hotspot in the Southern Volcanic Zone of the Andes (Nahuel Huapi National Park, Patagonia, South America)

Carolina Soto Cárdenas 0000-0001-5886-7780, Zaida Fernandez, Marina Arcagni, Andrea Rizzo and María C. Diéguez 0000-0002-8241-3719
 

Movement of dissolved organic matter and mercury in wet and dry seasons for a shallow (left) and a deep (right) connected lakes of Andean Patagonia.

Environmental context. The pristine oligotrophic lakes of Andean Patagonia are influenced by volcanic eruptions and atmospheric deposition. This study focuses on mercury (Hg) dynamics in two connected lakes in a natural Hg hotspot of the southern Andes. The lake waters have low dissolved organic carbon and moderate to high Hg concentrations, resulting in high Hg availability. These promote Hg binding to natural particulates, thereby favouring its incorporation into food webs. (Image credit: Carolina Soto Cárdenas)

EN24089Mercury wet deposition in the urban and industrialised region of Campinas, south-east Brazil

Amauris Hechavarria-Hernandez, José Lucas Martins Viana and Anne Hélène Fostier 0000-0002-6250-7419
 

A scheme depicting mercury wet deposition and analysis.

Environmental context. Wet deposition is a primary mechanism for transferring atmospheric mercury (Hg) to the Earth’s surface. In Brazil, as well as in the rest of the Southern Hemisphere, only limited data on wet Hg deposition are available. This article addresses this gap by providing a comprehensive dataset from nearly 2 years of monitoring, focusing on mercury concentrations in rainwater and wet Hg deposition in Campinas, one of the largest industrial and populated regions in São Paulo state (south-east Brazil).
