“…Dahmardeh Behrooz et al [35] observed that old European hedgehogs had high levels of Hg in spines (94 ppb) in comparison with juveniles (20 ppb) or pups (2 ppb); thereby a positive correlation between Hg levels in spines and age was observed. As widely described for other mammals, this observation has also been previously shown in the fur of bats [43,99], mustelids [38,56,101], and other terrestrial wild mammals [58].…”

Trace Metals in the Environment

As highly relevant environmental contaminants, metals and metalloids have been extensively evaluated for decades in biomonitoring programs, due to their potential toxicity at low levels and highly persistent in many ecosystems. When considering chemical analysis, metal quantification has been carried out through conventional methods, based in the determination of their levels in internal organs, such as liver and kidney. Nevertheless, non-invasive methods constitute an alternative response regarding trace elements biomonitoring studies. Specifically, keratinized tissue from terrestrial mammals (such as hair, nails or spines) presents a high accumulation rate, giving relevant information about heavy metal dynamic at internal levels, and most particularly, a chronic exposure. This critical review focuses on the use of non-invasive tissues, mainly hair and spines, as adequate tools on heavy metals assessment, specifically mercury (Hg) and lead (Pb), in biomonitoring studies performed in terrestrial wild mammals.
