| Zusammenfassung |
| Tree rings represent an important tool to monitor, over time, environmental information
and anthropogenic emission related to the region where trees grow. Isotopic and
dendroecological analyses on wood can detect the physiological responses of trees to
environmental changes and are a powerful resource for the quantitative assessment
of pollution trends. In the natural reserve of “Bosco Fontana” (Mantova, North
Italy), eight specimen of Quercus robur were sampled at increasing distance from
the heavily trafficked street SS236. Dendroecological and carbon (13C and 14C),
nitrogen (15N) and oxygen (18O) isotopic analyses were performed to understand the
spatial and temporal effect of the vehicle exhaust on tree growth. Cellulose was
extracted from wood for C and O measurements; instead, movable nitrogen was
removed to select only structural nitrogen, avoiding interferences in N analyses. A
specific protocol of measurement of δ15N with IRMS in low nitrogen concentration
wood ( |
