Abstract
A biomonitoring survey was performed to measure PCDD/Fs deposition for mapping spatial dispersion of dioxins in the region of Setúbal, Portugal. Since, no single lichen species was found occurring in the whole study area, samples of two lichen species — Ramalina canariensis and Xanthoria parietina — were collected. These two species have different abilities to monitor the same pollutant concentration. As they are spread preferentially in two different areas, they should be viewed as two complementary indicators of dioxins concentration. The objective of this study was to build a geostatistical model that integrates, within a single coherent model, the two complementary visions of the same reality given by contaminant concentrations measured in the two sampled lichen species. For this purpose, a geostatistical model was built to integrate both lichen species’ data to obtain a unique map of PCDD/Fs deposition. This model uses co-located cokriging with local spatial correlations in order to estimate the primary data. Some of the congeners of dioxins were also estimated with the same methodology.
