Critical evaluation of a new passive exchange-meter for assessing multimedia fate of persistent organic pollutants at the air-soil interface

Popis výsledku v původním jazyce

A new passive exchange meter (PEM) to measure inter-compartment fluxes of persistent organic pollutants (POPS) at the interface between soil and the atmosphere is described. The PEM uses labeled reference compounds (RC) added in-situ to vegetation litterdeployed in open cylinders designed to trap the vertical downward export of the RCS while allowing free exchange of POPs between litter and air. Fluxes of native compounds (bulk deposition, volatilization and downward export) are quantitatively tracked.One scope of the PEM is to investigate the influence of biogeochemical controls on contaminant re-mobilization. The PEM performance was tested in a subtropical forest by comparing measurements under dense canopy and in a canopy gap; conditions in whichdeposition and turn-over of organic matter (OM) occur at different rates. Significant differences in fate processes were successfully detected.
