摘      要：The bioaccumulation of PAHs and metal elements in the indigenous lichens Xanthoria parietina was monitored during two years at a quarterly frequency,in 3 sites of contrasted anthropic *** impact of the meteorological factors(temperature,relative humidity,rainfall,wind speed)was first estimated through principal component analysis,and then by stepwise multilinear regressions to include wind *** pollutants levels reflected the proximity of atmospheric emissions,in particular from a large industrial *** humidity and mild temperatures,and in a lower extent low wind speed and rainfall,also favored higher concentration *** contributions of these meteorological aspects became minor when including wind direction,especially when approaching major emission *** bioaccumulation integration time towards meteorological variations was on a seasonal basis(1–2 months)but the wind direction and thus local emissions also relied on a longer time scale(12 months).This showed that the contribution of meteorological conditions may be prevalent in remote places,while secondary in polluted areas,and should be definitely taken into account regarding long-term lichen biomonitoring and inter-annual *** the same time,a quadruple sampling in each site revealed a high homogeneity among supporting tree species and *** resulting uncertainty,including sampling,preparation and analysis was below 30%when comfortable analytical conditions were ***,the occurrence of unexpected events such as a major forest fire,permitted to evaluate that this type of short,although intense,events did not have a strong influence on PAH and metals bioaccumulation by lichen.
