Navigating the complexity of detrital rutile provenance: methodological insights from the Neotethys Orogen in Anatolia [PDF]

open access: yesGeochronology
Sedimentary provenance is a powerful tool for reconstructing convergent margin evolution. However, single mineral approaches, like detrital zircon, have struggled to track sediment input from mafic and metamorphic sources.

Urinary lead in relation to combustion-derived air pollution in urban environments. A longitudinal study of an international panel

open access: yesEnvironment International, 2019
Background: Urinary lead (Pb) is generally considered to have limited use in biomonitoring environmental exposure to lead. Carbon load in airway macrophages (AM BC) is an internal marker to assess long-term exposure to combustion-derived aerosol ...
