Canopy influence on trace metal atmospheric inputs on forest ecosystems: Speciation in throughfall [PDF]

, 2010
Trace Metal (TM: Cd, Cu, Ni, Pb, Sb and Zn) atmospheric inputs have been studied on six forested sites. In order to evaluate canopy interaction with atmospheric inputs, TM have been measured in both Open Field Precipitation (OFP) and Throughfall (TF ...
