“…the advent of multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS), as well as continual rening of preparation/separation and pre-concentration methods 1 have allowed inclusion of heavier stable elements in the 'isotope toolbox' and the number of published stable isotope studies has grown exponentially in the last decade. 16 For example, in environmental studies involving bio-indicators, Pb 11,17 and Sr 18 isotopes have been relied upon for at least the past three decades, whereas Os, [19][20][21][22] Cd 23 and Tl have been relatively new additions contributing to the expanding array of investigations.…”

“…Pallavicini et al present an ICP-SFMSbased method for osmium quantification in biological material. 322 For reliable Os quantification at environmentally relevant concentrations in small-sized biological samples, preparation and handling of the samples is of utmost importance. The isotopes 189 Os, 190 Os and 191 Os were determined at low resolution in several organs of vole (rodents), such as liver, kidney, lung and muscle.…”

ICP-MS is based on the formation of (preferentially monovalent positively) charged atomic ions in an inductively coupled Ar plasma at almost 10 000 K. The ions formed are transferred from the plasma source at ambient pressure into a mass separator operated at high vacuum via a set of cones. The ions are separated according to their mass/charge ratio in the mass separator (quadrupole, magnetic sector field or time-of-flight mass separator). In most cases, the ions are detected using a secondary electron multiplier; in some set-ups (also) a Faraday cup can be used. Single-collector (scanning mass spectrometer usually used for quantitative elemental analysis) or multicollector (static operation of mass spectrometer for precise isotope ratio analysis) configurations can be found (Figures 12.1 and 12.2).

Diet shifts are common in mammals and birds, but little is known about how such shifts along the food web affect contaminant exposure. Voles are staple food for many mammalian and avian predators. There is therefore a risk of transfer of contaminants accumulated in voles within the food chain. Osmium is one of the rarest earth elements with osmium tetroxide (OsO) as the most toxic vapor-phase airborne contaminant. Anthropogenic OsO accumulates in fruticose lichens that are important winter food of bank voles (Myodes glareolus). Here, we test if a) anthropogenic osmium accumulates in bank voles in winter, and b) accumulation rates and concentrations are lower in autumn when the species is mainly herbivorous. Our study, performed in a boreal forest impacted by anthropogenic osmium, supported the hypotheses for all studied tissues (kidney, liver, lung, muscle and spleen) in 50 studied bank voles. In autumn, osmium concentrations in bank voles were even partly similar to those in the graminivorous field vole (Microtus agrestis; n=14). In autumn but not in late winter/early spring, osmium concentrations were generally negatively correlated with body weight and root length of the first mandible molar, i.e. proxies of bank vole age. Identified negative correlations between organ-to-body weight ratios and osmium concentrations in late winter/early spring indicate intoxication. Our results suggest unequal accumulation risk for predators feeding on different cohorts of bank voles.
