Summary: This study developed a suspect screening method based on industrial compounds with bioaccumulation potential. Results showed that SQDIA has a significantly lower false-positive rate compared to standard DIA. Through suspect screening and nontargeted screening, multiple pollutants were identified, with some compounds confirmed through standards and structural analysis.

Summary: This paper focuses on the chemical analysis of human scent samples from fired cartridge cases and their comparison with scent samples obtained under laboratory conditions. Comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometer was used for analyzing the scent samples. The results confirmed the stability of human scent evidence and its potential application in forensic purposes. The qualitative findings align with previous studies on the composition of human scent and the chemical composition of human fingerprints. Statistical analysis using similarity algorithms yielded a perfect identification rate of the scent inflictor when comparing the scent samples secured from fired cartridge cases with those collected under laboratory conditions.

Summary: This study identified and quantified volatile organic compounds (VOCs) in fermented sea bass using gas chromatography-ion mobility mass spectrometry (GC-IMS) and gas chromatography-mass spectrometry (GC-MS). Aldehydes were found to be the principal contributors to the overall flavor of fermented sea bass, and several characteristic VOCs were identified. GC-IMS was demonstrated to rapidly detect VOCs, providing a theoretical basis for studying flavor formation in fermented sea bass.

Summary: Analytical techniques for chemical analysis of oil and its transformation products have greatly benefited from research following the Deepwater Horizon oil spill. Advanced gas chromatography and high-resolution mass spectrometry have provided a better understanding of the composition and complexity of oil, while novel separation approaches have increased the information available on spilled oil. The development of these techniques is important for future oil spills and investigations into the fate and effects of petroleum and dispersants.

Summary: This study describes for the first time the composition and content of the essential oil of Gynoxys laurifolia (Kunth) Cass. collected in Loja province, Ecuador. The essential oil is dominated by sesquiterpene hydrocarbons (about 45%) and monoterpene hydrocarbons (about 25-30%). In addition, enantioselective analysis of some common chiral terpenes was conducted. Due to the wildness of the plant and the relatively low distillation yield, no industrial applications can be identified at this stage for this essential oil.

Summary: This study analyzed the residues from four archaeological ceramic sherds to determine the contents and probable functions of the original vessels. The analysis revealed significant differences in the residues, reflecting variations in decoration, manufacture, and ceramic typologies. One vessel contained residue indicative of oils, another had residues consistent with scented materials or medicinal contents, a third probably held medicinal material, and the fourth sherd suggested it may have held chemicals or explosive ingredients. This residue analysis provides insights into luxury items, medicines, technology, and trade in medieval Jerusalem.

Summary: In this study, we used advanced mass spectrometry techniques to analyze crude oil compounds and proposed a new analytical approach. The method involved three-dimensional visualization of mass spectrometry data, multivariate statistical analyses, and a combination of multivariate statistical and conventional analytical methods. The results identified specific compounds as differential markers for distinguishing between different crude oil samples. The study also discussed the potential application of this method in petroleum-contaminated groundwater.

Summary: This paper presents new interdisciplinary research results on the commodities contained in the ovoid amphorae of Hispania Ulterior/Baetica. The study found that the majority of these amphorae were coated with pitch from Pinaceae trees and contained grape derivatives, shedding light on wine production in the region during the late Republican period. This use of ovoid amphorae for carrying wine is unexpected, as it was previously thought that similar amphorae types in other regions were used for olive oil.

Summary: The aim of this research is to investigate various aspects related to combustion structures in Iron Age archaeological sites, including efficiency, fuel types, structure maintenance, and domestic activities. An experimental programme was conducted using replica structures and different fuel sources, and variables such as heating and time were measured to determine their impact on the combustion process. Multiple methodologies were applied for integrated analyses, and observations and data recorded during the experiments contributed to a better understanding of Iron Age combustion structures.

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.
