Summary: This study shows that lead isotopes in lead white pigment can be used as an additional diagnostic tool to determine the production time of 17th century Dutch paintings. Analysis of 77 well-dated paintings from 27 different Dutch artists reveals significant changes in the source of lead used in lead white at the start, middle, and end of the 17th century.

Summary: This study predicts the long-term transport of heavy metals at an abandoned e-waste recycling site, considering historical pollution activities, land use, and metal pollution dynamics. The results show severe heavy metal contamination in the soil profiles, with copper and zinc primarily accumulating in the upper layers and significant migration of cadmium and lead in the deeper layers. Pb isotopes and the Hydrus model trace the sources of Pb contamination and predict its distribution, indicating the significant contribution of e-waste recycling activities and minor impacts from other anthropogenic sources. Additionally, the model predicts a concentration of 60% of Pb contaminants in the surface soil within the next 30 years. These findings provide a foundation for evaluating and remediating abandoned e-waste recycling sites.

Summary: The study found that there is isotopic heterogeneity in lead white within individual paintings, while pure pigment from 16th-century Venetian lead white is isotopically homogeneous. The evolution from pure pigment to artwork is associated with an increase in the heterogeneity of lead isotope ratios.

Summary: The lead isotopic composition analysis of 15 tin bronze objects recovered at Baba Jilan suggests they may have originated from multiple copper sources in Iran, particularly from the Urumieh-Dokhtar and the Sanandaj-Sirjan zones. These zones have been identified as ancient mining areas and previously thought to be sources for metals found at other sites on the Iranian Plateau.

Summary: The U-Th-Pb system is widely used in Earth science to date and trace geological events. However, there are two major paradoxes in the Pb isotope systematics. This study reviews the proposed solutions and presents a new framework for understanding the evolution of Pb isotopes in Earth materials. The new model suggests distinct Pb evolution paths for different components of the Earth, with the present-day upper continental crust being one end member.

Summary: The study investigated the sources of atmospheric lead in Beijing, identifying anthropogenic sources contributing approximately 85% annually, with natural sources accounting for the rest of 15%. Natural sources contributed around 9.4% in spring, 29.7% in summer, 16.0% in autumn, and 6.1% in winter, indicating a potentially higher contribution of natural sources on clear days.

Summary: To analyze the isotope distributions of PM2.5 in residential buildings and identify their sources, carbon and lead isotope ratios were analyzed in indoor and outdoor air. Factor analysis was used to investigate sources and isotopic analyses were compared. The seasonal variations of delta C-13 values or Pb isotope ratios in indoor and outdoor air were not significant. Traffic emissions were identified as the major contributor to PM2.5 in both indoor and outdoor air. Indoor air in buildings with poor ventilation conditions showed significantly lighter delta C-13 values than outdoor air. Spatial and seasonal variations of isotopes were similar in residential buildings, providing valuable information for source identification of indoor PM2.5.

Summary: The study reveals that anthropogenic lead is widespread and dominant in the western Arctic Ocean, with significant contributions from historic aerosol lead deposited from Europe and Russia during the 20th century. The remobilization of this lead, especially in water layers with higher concentrations, highlights the impact of human activities and environmental changes on the Arctic. Detecting 20th century Eurasian lead in deep water also provides insights into ventilation ages and helps constrain sources of contaminants in Arctic seawater.

Summary: Despite over a century of archaeological research, we have limited information about the lives of the first inhabitants of Puerto Rico, known as the Archaic or Pre-Arawak people. This study presents the analysis of five individuals from the Ortiz site in Puerto Rico, shedding light on their mortuary practices, paleodiet, and potential social organization. The findings provide insights into the earliest lifeways in Puerto Rico, indicating standardized mortuary practices and the presence of both male and female adults. Stable isotope analysis reveals dietary differences from later periods, and dental pathology suggests heavy wear from diet and/or non-masticatory function. The direct AMS dating confirms these as the oldest burials on the island, hinting at a higher cultural complexity than previously thought.

Summary: The objective of this study was to create a comprehensive database compiling lead isotope analyses of copper and/or lead ores. The database includes isotopic signatures from geological and archaeological studies, covering a large area, and excludes incomplete and unrelated data. The database is a valuable tool for provenance studies.

Summary: In this study, the preformation probability Pc of cluster radioactivity in the NpNn scheme for the effective number of valence particles in trans-lead nuclei was investigated. Pc was explored in a microscopic and model-dependent way. The results showed that Pc is linearly related to NpNn and NpNnI, and different approaches were used to calculate Pc.

Summary: This study uncovers a previously hidden feature in the conduction band states of lead halide perovskites and finds that it is strongly influenced by the strength of electronic coupling between the A-cation and bromide-lead sublattice. The findings provide an alternative mechanism for understanding slow hot carrier cooling and emphasize the optoelectronic role of the A-cation.

Summary: This study collected soil and moss samples from different slopes and altitudes in Shennongjia Mountain to identify the sources of lead and the regulation mechanisms of altitude and slope on its distribution. The results showed that atmospheric deposition was the main source of lead, and altitude determined the distribution pattern of atmospheric lead.

Summary: This paper presents a study on copper production and distribution in Lower Austria's southeastern region during the Late Bronze Age, focusing on the chemistry and isotopic character of artifacts from a small copper mining site at Prigglitz-Gasteil. The analysis revealed that the copper from Prigglitz-Gasteil was relatively pure, with imported copper alloys mainly originating from the Slovakian Ore Mountains and being mixed or recycled with locally produced copper. The study highlights the complexity of metal production processes in the region and the need for further geochemical research to draw definitive conclusions on ore-to-metal production.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
