“…Kidney or liver are most commonly used as bioindicator of Se in the environment [e.g. 38 , 39 , 175 , 176 ]. We found the highest Se concentration in kidney for all individuals (Tables 2 and 3 ), while it was also found in nearly all other tissues that we analyzed in lower concentrations (Tables 2 and 3 ; Fig.…”

The ionome—an important expression of the physiological state of organisms—is poorly known for mammals. The focus on particular tissues—such as liver, kidney, and bones—in biomonitoring of environmental pollution and potential deficiencies is based on widely held assumptions rather than solid knowledge of full mammalian ionomes. We examined the full ionome of Red deer (Cervus elaphus) and Wild boar (Sus scrofa), two commonly used mammals for biomonitoring, in a Dutch protected nature reserve (Veluwezoom). We used four individuals per species. We dissected 13 tissues and organs from each individuals (eight in total) of each species and measured 22 elemental concentrations in each. We assessed, for each element, how concentrations varied across tissues within and between individuals. Based on existing literature, we put our findings in the context of their function in the mammalian body. We found that the ionome was highly variable between as well as within the two species. For most elements, tissues containing the highest and lowest concentration differed between individuals. No single tissue accurately represented the accumulation of toxic elements or potential deficiencies in the bodies. Our assessment of the element’s biological roles revealed a serious lack of reference values. Our findings imply that analyses of commonly used tissues in biomonitoring do not necessarily capture bioaccumulation of toxins or potential deficiencies. We recommend establishing a centralized database of mammalian ionomes to derive reference values in future. To our knowledge, our study is one of the most complete assessments of mammalian ionomes to date.

“… 32 – 37 ]. For example, Nowakowska et al [ 38 ] used liver and kidney samples of Wild boar to examine environmental levels of Se in Poland. Vikøren et al [ 39 ] used the liver as an indication for the cupper (Cu), Co and Se concentration in wild Red deer in Norway.…”

“…The lack of reference values, and the severe elemental variation within and among age and sex groups as we report in this paper, limit the use of wild-living animals for biomonitoring purposes, which is usually based on a limited number of elements in only a few tissues [e.g. 17 , 32 , 110 ]. We believe that it is important to increase our understanding of this variation in more detail before this can be applied to biomonitoring purposes.…”

Abstract(1) In mammals, the mineral nutrient and trace elemental composition of the body - the ionome - differs among individuals. It has been hypothesized that these differences may be related to age and sex, both for ecotoxic and essential elements. (2) We investigated whether and how intraspecific ionomic variation is related to age and sex in Fallow deer (Dama dama). We tested the predictions that concentrations of ecotoxic elements increase with age, that ionomic variation is lower among young individuals than among older individuals, and that reproductive females (does) have the lowest concentrations of essential elements. (3) Culled animals of different sex and age were obtained from a single protected area. The animals were dissected to collect 13 tissues, and concentrations of 22 different elements were measured in a sample of each tissue. (4) We described substantial ionomic variation between individuals. Some of this variation was related to age and sex, as predicted. Based on the limited existing knowledge on chemical element allocation and metabolism in the body, sex-related differences were more difficult to interpret than age-related differences. Since reference values are absent, we could not judge about the consequences of the elemental values that we found. (5) More extensive ionomic surveys, based on a wide range of elements and tissues, are needed to enlarge the understanding of within-species ionomic variation and potential biological, ecological, and metabolic consequences.
