“…In addition, our results would be also supported by a rodent study (including Apodemus spp.) in which authors found no gender differences in the concentration of various chemical elements in muscle and bone samples [ 80 ]. Likewise, no differences in isotopic values depending on age, sex or breeding condition have been found in several rodent species, including the wood mouse [ 51 , 70 , 74 , 75 , 81 , 82 , 83 , 84 ].…”

The analysis of carbon and nitrogen elemental (C, N) and isotopic compositions (δ13C, δ15N) in faeces are considered reliable methodologies for the study of diet in wildlife. Here, we tested the suitability of these techniques to detect variations in the amount of food intake. We captured wild wood mice (Apodemus sylvaticus) with Sherman live traps where bait access was initially free, and later it was experimentally limited inside by four different devices to cause intended variations in the amount ingested. The total C and N (%) and stable δ13C and δ15N isotopic values were determined for the bait and in mice faecal samples. Faecal values were lower than bait ones except for N, likely due to animal matter ingested before capture. No significant differences in total C, N and δ13C were found due to individual traits. However, breeding males showed higher δ15N values than breeding females, probably due to differences in energy and protein demands between both sexes during the breeding season. Only δ13C detected food intake variations (≥2 g). Despite further research being needed, these results initially support the potential of δ13C to provide information on the amount ingested, thus being useful to complement trophic ecology studies.

“…Heavy metals are necessary for the efficient functioning of biological systems, as long as their concentration in fruits and vegetables is balanced, in order not to produce a series of metabolic disorders (Fawad et al, 2017). In this sense, heavy metal concentrations and nutritional intake from fruits and vegetables are important for maintaining human health (Balčiauskas et al, 2022).…”

The current study has investigated the accumulation and transfer coefficient for three heavy metals (Cu, Pb, Zn) found in the contaminated soil with three concentrations (c1=1.5%, c2=3.0%, c3=4.5%, c4=6.0%), obtained by mixing the three metals, in blueberry and raspberry fruits. The pots in which the shrubs were planted were loaded with fertile soil which was mixed and homogenized in turn with each of the three solutions of different concentrations. The highest accumulation in blueberry fruits was recorded for zinc, then copper and the lowest for lead, while for raspberries the highest results was recorded for zinc, then lead and the lowest for copper. The findings are valid for all four concentrations used. The transfer coefficient decreases as the concentration of heavy metals increases, thus for high heavy metal concentrations, the values of the transfer coefficient are very low, and for small heavy metal concentrations in the soil, the values for the transfer coefficient are higher. From the assessment of accumulation and transfer of heavy metals to berries (blueberries and raspberry) grown in the contaminated soil, it was concluded that all concentrations of the copper, lead and zinc mix have shown a low risk for human consumption.

This study assessed environmental metal and metalloids (TE) levels using hair of Apodemus sylvaticus as a non-lethal biomonitor. TE decreased as follows: Zn > Al > Fe > Cu > Pb > Cr > Ni > Mn > Cd > Se > As > Hg; TE widely distributed in soils as Zn, Al, Fe, and Cu, are more abundant than those of ecotoxicological interest, such as Cd, Se, As and Hg. Cd, Pb, Cu, and Cr concentrations are highly variable, while Zn, Fe, and Mn are less variable. TE in hair are below the threshold levels in soil and decrease the same way in both sexes. Concentrations in soil and hair are significantly related, and their level can be modulated both by homeostatic control of essential metals and absorbance from the soil by keratin. Slight differences in Ni and Cr can be related to the differing behaviour of males and females during reproduction. A scarce tendency toward mercury bioaccumulation has been observed in both sex and age classes; from an ecological point of view, these data suggest that the species is a primary consumer, feeding more on the leaves and seeds than on small invertebrates.
