Rhizosphere microbial detoxification and phosphorus solubilization drive ecological remediation of Pb–Zn contaminated soils

PLANTS, PEOPLE, PLANET, EarlyView.
Heavy metal contamination of soils poses a serious threat to ecosystem health and food security worldwide. This study investigated how native plants, such as Artemisia annua and Buddleja davidii, interact with soil microbes in Pb–Zn waste slag areas. We found that these plants stimulate microbes, which improve phosphorus availability and reduce metal ...

Quantification of Alkali‐Fluoride Nanoparticle Dissolution in Aqueous Media as a Function of Crystallinity and Surface Modification

Particle &Particle Systems Characterization, EarlyView.
Fluoride release kinetics from uncoated and coated β−NaYF4$\ubeta-{\rm NaYF}_4$ and LiYF4${\rm LiYF}_4$ in aqueous solutions are quantified using an ion‐selective electrode coupled to a dialysis compartment. TEM/DLS/ICP‐OES and speciation‐aware modeling complement the fluoride release results.

Metals' Adsorption Onto Environmental Microplastics at Shoreline Sediments

X-Ray Spectrometry, EarlyView.
ABSTRACT This study assessed trace element concentrations and microplastic (MP) contamination in three sandy beaches on the southern coast of Ilha Grande (Rio de Janeiro, Brazil). Environmental MPs were manually extracted from sand samples, and beaches were classified using the microplastic pollution index (MPPI).

Optimal timing and rate of nitrogen fertilizer use: An integrated network technology approach

American Journal of Agricultural Economics, EarlyView.
Abstract Both the rate and timing of crop fertilizer application play an important role in agricultural productivity. However, inefficient fertilizer use can significantly increase production costs, water pollution, and greenhouse gas emissions. To capture both the spatial heterogeneity and dynamic nature of this problem, we develop a multi‐stage ...

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War

Anthropology of Consciousness, EarlyView.
ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

The exploitation of silver deposits in early medieval Europe: some documentary, economic and social problems

Archaeometry, EarlyView.
Abstract Focusing on Southern Europe, this article sheds light on the mining landscape of the early Middle Ages. Based on the current state of historical and archaeological knowledge, the article raises a number of questions that can be extended to other European regions.

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, EarlyView.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...
