Sr-Nd ISOTOPES IN MOSSES FROM ROMAGNA (ITALY) AND THEIR ENVIRONMENTAL SIGNIFICANCE

Francesca Castorina, Umberto Masi

Abstract


Sr-Nd isotopes were applied for the first time to the study of several moss samples from a transect stretching through Romagna from the Apennines to the Adriatic sea coast. The isotopic data suggest that the mosses uptake Sr and Nd via atmospheric depositions from both marine carbonates and old siliceous crustal rocks. Anthropic pollution cannot be precisely evaluated because of the lack of univocal isotopic signature of the sources.
