“…The observed pattern in spatial distribution of Os concentration in bank voles and fruticose lichens is in close agreement with previous results on Os in a variety of plant tissues from the same region (Rodushkin et al 2007b(Rodushkin et al , 2007c. Whole body Os concentrations in bank voles collected at 122 km distance from the pollution source (<0.3 pg g −1 ) probably reflect the upper limit of background concentration range characteristic for the study area.…”

“…Whole body Os concentrations in bank voles collected at 122 km distance from the pollution source (<0.3 pg g −1 ) probably reflect the upper limit of background concentration range characteristic for the study area. In our sparsely populated study area, Os from automobile catalysts can most likely be excluded as a contributing factor (see also Rodushkin et al 2007b). Interestingly, even though Os concentrations did not indicate any anthropogenic Os source, the 187 Os/ 188 Os ratio for samples from this remote locality (approximately 0.35) is much less radiogenic than for local inorganic soil layers (1.02-1.68) (Rodushkin et al 2007b).…”

“…The environmental effects of Os are poorly understood, mainly due to the analytical challenges associated with Os determination at environmentally relevant levels. Only recently, accumulation of Os has been observed in cryptogams (mushrooms, mosses, and lichens) and vascular plants (e.g., bilberry, birch, and lyme grass) in northern Sweden (Rodushkin et al 2007b). The steelwork in Tornio, Finland was identified as the main source of the anthropogenic Os in the region (Rodushkin et al 2007c).…”

Osmium tetroxide (OsO 4 ) is one of the most toxic air contaminants but its environmental effects are poorly understood. Here, for the first time, we present evidence of osmium uptake in a common herbivore (bank vole, Myodes glareolus) in boreal forests of northern Sweden. Voles (n=22) and fruticose arboreal pendular lichens, the potential main winter food source of the vole, were collected along a spatial gradient to the west of a steelwork in Tornio, Finland at the Finnish-Swedish border. 187 Os/ 188 Os isotope ratios increased and osmium concentrations decreased in lichens and voles along the gradient. Osmium concentrations in lichens were 10,000-fold higher than those in voles. Closest to the steelwork, concentrations were highest in kidneys rather than skin/fur that are directly exposed to airborne OsO 4 . The kidney-to-body weight ratio was higher at the two localities close to the steelwork. Even though based on a small sample size, our results for the first time demonstrate that osmium is taken up, partitioned, and accumulated in mammal tissue, and indicate that high kidney-to-body weight ratios might be induced by anthropogenic osmium.

“…Several authors applied Al as a crustal indicator (Bargagli 1990b;Wiersma et al 1992;Calvelo et al 1997;Varrica et al 2000;Carignan et al 2002;Cloquet et al 2006;Rodushkin et al 2007;Merešová et al 2008;Boamponsen et al 2010). In certain cases, Al is not available as a determinant factor of crustal identity and Mn is selected as a crustal reference (Machado et al 2004).…”
