Investigating the relationship between non-occupational pesticide exposure and metabolomic biomarkers
The relationship between pesticide exposures and metabolomics biomarkers is not well understood. We examined the changes in the serum metabolome (early biomarkers) and the metabolic pathways associated with various pesticide exposure scenarios (OPE: overall exposure, PEM: exposure in months, PEY: exposure in years, and PEU: reported specific pesticides use) using data from the Northern Finland Birth Cohort 1966 31-year cross-sectional examination…
Towards a marine strategy for the deep Mediterranean Sea
Organic Air Quality Markers of Indoor and Outdoor PM2.5 Aerosols in Primary Schools from Barcelona
Airborne particulate matter with an aerodynamic diameter smaller than 2.5 μg, PM 2.5 was regularly sampled in classrooms (indoor) and playgrounds (outdoor) of primary schools from Barcelona. Three of these schools were located downtown and three in the periphery, representing areas with high and low traffic intensities. These aerosols were analyzed for organic molecular tracers and polycyclic aromatic hydrocarbons (PAHs) to identify the main sour…
Atmospheric patterns driving Holocene productivity in the Alboran Sea (Western Mediterranean)
High-resolution paleoproductivity variations have been reconstructed in a productive cell in the Alboran Sea for the Holocene. Fossil coccolithophore assemblages have been studied along with the [Formula: see text]-estimated sea-surface temperature (SST) and other paleoenvironmental proxies. The appearance of this cell is suggested at 7.7 ka cal. BP and was linked to the establishment of the western anti-cyclonic gyre. From that time until the pr…
Climate change and coastal hydrographic response along the Atlantic Iberian margin (Tagus Prodelta and Muros Ría) during the last two millennia
The Tagus Prodelta (W Portugal) and the Muros Ría (NW Spain) are areas of high deposition rates registering high-resolution palaeoclimatic records for western Iberia. We compare the climatic conditions of the two areas over the last two millennia based on proxies of temperature (sea surface temperatures and oxygen isotopes), continental input (grain size, iron and magnetic susceptibility) and productivity (inorganic and organic carbon, carbon iso…
Saharan Dust Transport and High-Latitude Glacial Climatic Variability
Millennial to submillennial marine oscillations that are linked with the North Atlantic's Heinrich events and Dansgaard–Oeschger cycles have been reported recently from the Alboran Sea, revealing a close ocean-atmosphere coupling in the Mediterranean region. We present a high-resolution record of lithogenic fraction variability along IMAGES Core MD 95-2043 from the Alboran Sea that we use to infer fluctuations of fluvial and eolian inputs to the …
The last 3000 years in the Ría de Vigo (NW Iberian Margin)
The hydrographic evolution of the Ria de Vigo (NW Spain) during the last 3000 years has been reconstructed using benthic foraminiferal assemblages, stable oxygen isotopes, molecular biomarkers and seasurface temperatures (SST) reconstructed from the U K 37 index. Benthic oxygen isotopes and SST records provide evidence of episodic salinity contrasts between surface and bottom waters. The comparison of SSTs with other climate records for the North…
Variability of the western Mediterranean Sea surface temperature during the last 25,000 years and its connection with the Northern Hemisphere climatic changes
Sea surface temperature (SST) profiles over the last 25 kyr derived from alkenone measurements are studied in four cores from a W‐E latitudinal transect encompassing the Gulf of Cadiz (Atlantic Ocean), the Alboran Sea, and the southern Tyrrhenian Sea (western Mediterranean). The results document the sensitivity of the Mediterranean region to the short climatic changes of the North Atlantic Ocean, particularly those involving the latitudinal posit…
Dansgaard‐Oeschger and Heinrich event imprints in Alboran Sea paleotemperatures
Past sea surface temperature (SST) evolution in the Alboran Sea (western Mediterranean) during the last 50,000 years has been inferred from the study of C 37 alkenones in International Marine Global Change Studies MD952043 core. This record has a time resolution of ∼200 years allowing the study of millennial‐scale and even shorter climatic changes. The observed SST curve displays characteristic sequences of extremely rapid warming and cooling eve…
Indicadores químicos de combustión en un hogar del Paleolítico Medio del yacimiento de Mediona I (Alt Penedès, Barcelona)
La aplicación del análisis químico orgánico a muestras arqueológicas es una técnica de desarrollo reciente. El estudio de la fracción lipídica (eso es, la fracción de materia extraíble mediante disolventes orgánicos) de restos sedimentarios en yacimientos permite recuperar una información inaccesible a otras técnicas de identificación aplicadas a la Arqueología. Este artículo describe de forma comparativa la fracción aromática del sedimento en el…
