Abstract: Vegetation samples from King George Island, Antarctica (62°05'S, 058°23'W) were collected in the austral summer of 2004-2005. Lichens (Usnea aurantiaco-atra and Usnea antarctica), mosses (Sanionia uncinata, Syntrichia princeps and Brachytecium sp.), and one angiosperm (Colobanthus quitensis) species were analyzed for persistent organic pollutants as well as ?13C and ?15N stable isotopes. The following contaminants were found above the method detection limit (MDL): HCB (0.141-1.06ngg-1 dry weight), HCHs (URL: http://dx.doi.org/10.1016/j.chemosphere.2011.07.047
