Ecorc’Air: A Citizen Science Project for the Biomonitoring of Vehicular Air Pollution in Paris, France

Claire Carvallo, Aude Isambert, C. Franke, L. Turcati, Yann Sivry, Sophie Coural, Mélina Macouin, Sonia Rousse, F. Fluteau

Airborne particulate matter (PM) is known to have adverse health effects and is a growing concern in urban areas. Spatial and temporal variability is difficult to assess with the few air quality stations typically available in cities. As an alternative, tree bark acts as a passive captor on which…

Ana Alves, Matthieu Paulhac Buisson, Pascale Louvat, Claire Rollion-Bard, Franck Bassinot, William Robert Gray, Guillaume Paris, Benoît Caron, Giulia Del Manzo, Anne Le Friant, Eva Moreno, Annachiara Bartolini

To date, little is known about the impact of super-eruptions on ocean biogeochemistry. Using boron isotopes ratios measured on planktonic foraminifera in the marine sediment core BAR94–25, we provide a high-resolution pH record in the Andaman Sea (North of Sumatra), spanning Marine Isotopic Stage 5…
