Summary: Determining the reliance on coastal resources in the past is crucial for understanding long-term social and economic development and assessing human health and environmental impacts. Through stable isotope analysis, this study challenges the assumption that prehistoric Mediterranean hunter-gatherers heavily exploited aquatic resources. By analyzing amino acids from skeletal remains, it is revealed that the El Collado population relied on local lagoonal fish and shellfish, rather than open marine species. This study highlights the maritime-oriented economies on the north-western Mediterranean coast during the Early Holocene.

Summary: Anthropogenic mercury emissions have led to adverse health effects on humans. This study utilized the MeHg Compound-Specific Isotope Analysis (CSIA) approach to track the lifecycle of mercury in Hg-emission areas. The results revealed distinct differences in the isotopes of MeHg and IHg in rice, fish, and hair. The CSIA approach proved to be effective in understanding the biogeochemical cycle of mercury and its impact on human exposure, providing valuable information for pollution control policies and protection of human health.

Summary: In this article, isotopic analysis of samples from Northern Greece was conducted to reconstruct the diet and climate of the Early Iron Age. The results showed that the diet in Agras was primarily based on C3 plants, with some contributions from C4 plants and freshwater fish. The isotopic values were in good agreement with those from other sites in Northern Greece, Croatia, and Hungary.

Summary: Sr-87/Sr-86 analysis of human skeletal remains is crucial in archaeology for understanding past human mobility. A systematic survey of modern flora and fauna in the Conchucos region mapped bioavailable Sr-87/Sr-86 signatures, revealing significant environmental variation and providing a baseline for future archaeological studies.

Summary: Isotopic analysis is widely used in archaeology to gain insights from various organic and inorganic materials, but there are issues with the quality and reporting of findings. This paper addresses weaknesses in traditional applications of isotopic techniques, focusing on sample selection, data handling, and results reporting. It provides advice on building comparative baselines, statistical analysis, and effective communication. The guidance aims to improve the use of isotopic techniques in archaeology.

Summary: This study assesses the source characteristics of coastal aerosols and evaluates the contribution of atmospheric deposition to particulate organic matter in surface seawater. The results show that biogenic and biomass sources, as well as fossil fuel combustion, are the major sources of total suspended particulates (TSP). Atmospheric deposition has a significant impact on suspended particulate matter and particulate organic carbon in coastal waters.

Summary: Isotope-labeled four polycyclic aromatic hydrocarbons were used to study the migration and distribution of PAH4 in oil and French fries during frying. The results showed that PAH4 mainly distributed in the crust of the French fries, especially five-ring PAHs. The migration of PAH4 was mainly caused by oil absorption of French fries, which was influenced by the fluidity and polar component of the oil. Higher frying temperature enhanced the crust ratio and porous structure of French fries.

Summary: Food quality, safety, and nutrient metabolism play a key role in human health. However, contaminants and metabolic dysregulation in food can be problematic. Chromatography-mass spectrometry technology, especially when combined with stable isotopes, is widely used in food analysis and nutrient metabolism research. This study provides an overview of stable isotope technology applications in quantifying contaminant residues and nutrient metabolism, aiming to contribute to effective analysis techniques for protecting food quality and human health.

Summary: This study investigates the carbon and nitrogen isotope fractionation characteristics during the degradation of atrazine in a constructed wetland. The observed isotope parameters are consistent with those observed in the cultivation of specific strains, indicating similarities in the biodegradation pathway and mechanism. However, variations in carbon and nitrogen isotope fractionation across different phases may lead to over- or underestimation of atrazine biodegradation extent. The accuracy of estimation improves when using the enrichment factor derived from batch cultivation of pore water. This study advances the application of compound-specific stable isotope analysis in tracking atrazine biodegradation in ecosystems, emphasizing the importance of carefully selecting and applying the enrichment factor for quantifying intrinsic biodegradation.

Summary: There has been more research on major economic, political, and social changes during the Medieval period in western and north-western Europe compared to eastern Europe. This study focuses on the diets of the inhabitants in the Polack region of Belarus in the 11-18(th) centuries using stable isotope analysis. The results show that the diets of urban and rural dwellers were similar with limited variation over time, which is different from the findings in western Europe.

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.
