Middle Paleolithic lithic and faunal assemblages throughout Eurasia reflect short-term Neanderthal occupations, which suggest high group mobility. However, the timing of these a key factor to assess mobility territorial range, remains unresolved. Anthropogenic combustion structures are prominent in record conceal information on intensity natural setting their associated human occupations. This paper examines concentration eleven from unit Xb El Salt, site Spain through geoarchaeological...
The primary challenge faced by researchers in multiresidue analysis is the development of efficient, environmentally friendly, and reliable methods to ensure quality, safety, traceability. QuEChERS method has demonstrated remarkable versatility achieving excellent results various matrices analytes. This approach offers flexibility selecting different solvents, salts, buffers for salting-out partitioning, as well employing varied sorbents clean-up process. emerged a greener alternative...
A new green alternative vortex-assisted dispersive liquid–liquid microextraction method based on a natural hydrophobic deep eutectic solvent was developed for the extraction of 14 phthalic acid esters and one adipate in cold infusions tonic waters. Analyses were carried out using ultra-performance liquid chromatography coupled to tandem mass spectrometry. Different mixtures monoterpene thymol (essential oil thyme) medium-chain fatty acids (octanoic decanoic acids) at different molar ratios...
Dispersive liquid-liquid microextraction (DLLME) was combined for the first time with NACE-UV selective determination of eight fluoroquinolone antibiotics (lomefloxacin, levofloxacin, marbofloxacin, ciprofloxacin, sarafloxacin, enrofloxacin, danofloxacin and difloxacin) in mineral run-off waters. Field-enhanced sample injection carried out order to improve sensitivity, whereas pipemidic acid used as internal standard. The BGE that provided complete separation analytes standard composed 3 M...
In this manuscript, a dispersive SPE method based on the use of multiwalled carbon nanotubes has been developed for determination 15 organophosphorus pesticides residues including some their metabolites (disulfoton sulfoxide, ethoprophos, cadusafos, dimethoate, terbufos, disulfoton, chlorpyrifos‐methyl, malaoxon, fenitrothion, pirimiphos‐methyl, malathion, chlorpyrifos, terbufos sulfone, disulfoton and fensulfothion) from real environmental waters (run‐off, mineral tap water) by GC with...
In this work, the analysis of alkylphenols, bisphenols and alkylphenol ethoxylates in bottled waters, kombuchas water kefir was performed through a vortex-assisted dispersive liquid-liquid microextraction method based on natural hydrophobic eutectic solvent. For purpose, mixtures monoterpenes fatty acids were employed. Different factors affecting extraction optimized validated terms matrix effect, linearity, limits detection recovery. Recovery values varied between 70.0 124.3% (except for...
In this work, an innovative green strategy has been developed for the analysis of twenty-seven endocrine disruptors, including bisphenols, alkylphenols and alkylphenol ethoxylates, phthalic acid esters one adipate in tropical beverages. For purpose, nine natural hydrophobic deep eutectic solvents based on terpenoids camphor, thymol menthol at different molar ratios were investigated first time as extractants liquid-liquid microextraction target analytes from coconut waters Aloe Vera drinks....
Abstract The indigenous populations of La Palma (Canary Islands), who arrived on the island from Northwest Africa ca. 2000 years B.P., were predominantly pastoralists. Yet, many aspects their subsistence economy such as procurement, management, and use wild plant resources remain largely unknown. To explore this, we studied 600–1100‐year‐old archaeological site Belmaco Cave, which comprises a stratified sedimentary deposit representative fumier . Here, present high‐resolution, multiproxy...
Plastics play an essential role in food packaging and processing. However, the migration of chemicals to may cause adverse effects on human health. For this reason, it is great importance assess presence these substances ensure its safety quality. The aim article review latest advances analysis potentially migratory plastics foodstuff, including target, non-target, simulant analyses during period 2019–2023. innovations are centred around development sample treatment procedures using...
