“…reproductive indicators, population imbalances, among others) (Ali & Khan, 2019 ; Ali et al, 2019 ; Castellanos et al, 2010 ; Levengood & Heske, 2008 ). Histopathological analysis can be performed in parallel with the metal(loid)s determinations to access lesions and organic effects of these compounds (McNamara, 2016 ), and the liver and kidney are the most used organs due to their role in the metabolism and excretion of xenobiotics (Jota Baptista et al, 2022 ). Previous studies in Europe have been assessing heavy metal(loid)s in several wild mammals.…”

The red deer is an ungulate and large game species. The contamination of the ecosystems by metal(loid)s may lead to the exposure of animals (as well as humans) through water and food resources. The direct contact of hunters and wild animal meat consumers with deer carcasses may be a potential contaminant source. This study aimed to determine the metal(loid)s’ concentrations in the liver and kidney of red deer from two regions of Portugal (Idanha-a-Nova and Lousã), and to relate these with histopathologic lesions. Thirteen young male deer were submitted to metal(loid) determination (As, Cd, Co, Cr, Cu, Pb, and Zn) by inductively coupled plasma mass spectrophotometry (ICP-MS) and histopathology examination. Renal Cd (8.072 ± 5.766 mg/kg dw) and hepatic Pb (3.824 ± 6.098 mg/kg dw) mean values were high, considering the maximum values for consumption established by the European Commission. The hepatic mean value of Cu was significantly higher in Idanha-a-Nova (150.059 ± 33.321 mg/kg dw), and it is at the Cu toxicity limit considered for ruminants (150 mg/kg). The pollution induced by Panasqueira mines (Castelo Branco) may be a possible explanation for some of the findings, especially the higher values of hepatic Cu and Pb found in Idanha-a-Nova deer. These results have high importance under a One Health perspective, since they have implications in public health, and pose at risk the imbalance of animal populations and ecosystems.

“…To our knowledge, all past studies of lead exposure in scavenging mammals have utilized invasive sampling via collection of blood (Boesen et al, 2019; Brown et al, 2023; Fuchs et al, 2021; Hivert et al, 2018; Rogers et al, 2012), teeth (Brown et al, 2022) or liver (Kelly et al, 2021). Recent reviews have highlighted the value of non-invasive sampling of heavy metal exposure in wild mammals (Jota Baptista et al, 2022). One non-invasive approach to investigating heavy metal exposure in mammals is through hair analysis, a technique used by some recent studies on non-scavenging mammal species such as fruit bats ( Pteropus spp.)…”

Lead (Pb) toxicity is a threat to scavenging wildlife across the globe. To allow inexpensive measurement of long-term lead exposure from archived wildlife tissues, portable X-ray fluorescence (XRF) devices have been optimized to measure lead concentrations in bone samples from avian species. In this study, we assessed portable XRF for hair lead measurement in an Australian mammalian scavenger, the threatened Tasmanian devil (Sarcophilus harrisii). We attempted to first validate the method by analysing relatively large (~1.0 g) hair samples from 39 deceased animals initially with XRF, and then with inductively coupled plasma mass spectrometry (ICP-MS) (validation study). We then measured lead concentrations via XRF only in a further 61 hair samples taken from live devils trapped in a plantation forestry landscape, where devils may scavenge on browsing marsupials that are regularly culled using lead ammunition (plantation study). Portable XRF hair lead measurement demonstrated a positive correlation with ICP-MS results (R2 = 0.95), although the relationship was weak at low lead concentrations. In the validation study, 95% of sampled Tasmanian devils had relatively low lead levels (≤ 3 mg/kg), but the remaining two animals showed considerably elevated lead levels (> 15 mg/kg), suggesting that harmful long-term lead exposure can occur in this species. In the plantation study, lead levels were comparable to those found in the hair of mammals in other studies, though a higher proportion (11%) of devils showed levels > 3 mg/kg than in the validation study, suggesting devils may have higher exposure to lead in a landscape subjected to regular culling of browsing mammals. Our results suggests that portable XRF is a promising emerging technology, and after some refinement, may allow non-invasive real-time measurement of lead concentrations in the hair of mammals.

“…Moreover, STM (including Apodemus sylvaticus and M. arvalis ) are considered as suitable bioindicators not only for REs but also for organic soil contaminants such as polychlorinated biphenyls, polybrominated diphenyl ethers, and/or polyaromatic hydrocarbons (Vávrová et al 2003 ; Marcheselli et al 2010 ; Rodriguez-Estival and Smits 2016 ; Voorspoels et al 2007 ). However, the recent review by Jota Baptista et al ( 2022 ) has pointed out that not all animal tissues and organs provide the same information or should be interpreted in the same way. While non-invasive samples are more accessible and less stressful, invasive samples provide more detailed information with clinical and ecological relevance.…”

The aims of this study were (i) to specify real risk elemetnt (RE) uptake by wild terresrial mammals (A. sylvaticus and M. arvalis), (ii) to describe RE distribution in critical organs such as the liver and kidney, and (iii) to determine potencial differences in RE toxicokinetics with regards to individual species or sex. Three groups of experimental animals were fed diets amended with soil and green biomass of hyperaccumulator Arabidopsis halleri with different RE levels. The contents of As, Cd, and Pb in the liver and kidneys of the animals reflected the element contents in the diet. Higher Cd and Pb accumulation ability was observed in A. sylvaticus compared to M. arvalis tissues, and an opposite pattern was recorded for As. Zn contents in tissues of both species remained unchanged, and total contents of Zn in the exposed animals even tended to decrease compared to the controls. Results of this study indicate a generally similar response of both species to elevated RE contents in the diet, confirming these wild rodents as suitable models for RE biomonitoring in ecosystems. However, our data highlights some distinction in As toxicokinetics in wood mice compared to that of field voles and a significantly higher accumulation of Pb and Cd in females. Therefore, factors of species and sex should not be overlooked if relevant data are to be obtained in environmental studies conducted on small terrestrial rodents.
