Assessment of Metal Contamination and Human Health Risk in the Buffalo River Estuary, Eastern Cape, South Africa

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in estuarine environments poses environmental and public health concerns, particularly where surface waters support domestic and subsistence uses. This study assessed the seasonal distribution, controlling mechanisms, and non‐carcinogenic health risks of selected metals (Mg, Al, Ba, Fe, Mn, and Zn) in the Buffalo River ...

Synthesis and Crystal Structure of Sb2O2[CO3] with Stereochemically Active Lone Electron Pairs at Elevated Pressures

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Sb2O2[CO3] was synthesized at 20 GPa in a laser‐heated diamond cell and is an antimony oxocarbonate with stereochemically active lone electron pairs on the antimony atoms. Its crystal structure is characterized by the presence of [CO3]2–‐groups and by interconnected “Sb2O5‐units” which form a Sb–O‐network within the b,c lattice plane.

The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

open access: yesArchaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.
