“…In medium-sized terrestrial mammals, Pb levels ranged from 0.19 ppm (C. lupus signatus from Italy) [27] to 2.95 ppm (Vombatus ursinus in a mining area from Australia) [114]. Mora et al [49] quantified 150 ppm of Pb in hair of Felis pardalis from Texas (US), these authors suggesting that the animal was exposed through consumption of preys captured near busy roadsides. In large mammals, the variation between species was even larger, ranging from 0.401 ppm in U. arc tos from Poland [76] to 13 ppm in Camelus sp.…”

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.

“…In the meantime, camel hair is a good indicator of pollution because of the high exposure of their feed to soil contamination (Mora, et al 2000). Rashed and Soltan, (2002) found that lead was higher in camel hair than in wool and goat hair.…”

The study assessed the quality and variability of camel hair fibres in arid regions of Egypt. Raw camel-hair samples were collected from fifteen Sudanese camels divided into seven males (414.60 ± 38.19 kg, BW) and eight females (401.67 ± 26.76 kg BW), and the study investigated the influences of animal sex on both the physical and chemical traits of camel-hair fibers. The relationships among physical properties and both mineral and amino acid content were studied. Camel’s sex had no significant effect on any of the studied traits including fibre diameter (FD), prickle factor (PF), medullated fibre (MF), staple length (SL) and staple strength (SS). In the meantime, no significant differences were found between males and females in fibers’ minerals contents except potassium, where fibres of females had significantly higher potassium content than those of males. For amino acids contents in camel fibres, camel sex had a significant effect only on glutamic acid, since fibres of males showed higher (P < 0.05) content than females. Fibre diameter had positive (P < 0.01) correlations with prickle factor (r = 0.83) and medullated fibres (r = 0.73). Zinc content in camel fibres was positively correlated with fibre diameter (r = 0.57; P < 0.05) and medullated fibres (r = 0.73; P < 0.01). Moreover, a significant (negative correlation coefficient P < 0.05) was found between fibre diameter and both sulfur and proline contents (r=-0.39 and − 0.56). Ammonia content in fibres was correlated negatively (P < 0.05) with prickle factor and elongation (r=-0.62 and − 0.58, respectively). The variability in the physical properties and chemical composition of Sudanese camel-hair fibers under subtropical desert conditions may shed light on the possibility of improving fiber quality.

“…These include, but are not limited to, native habitat loss and fragmentation, transboundary industrial air pollution, water quality and use issues (irrigation, distribution, and rights), and insecticide and contaminant occurrences in wildlife tissues (Custer and Mitchell 1987; Ellenson et al 1997; Fipps and Pope 2004; Leslie 2016; Mejia-Velazquez and Rodriguez-Gallegos 1997; Mora et al 2000; Mukerjee et al 1999; Schoolmaster 2010). Additional environmental problems include municipal solid waste, pesticide contamination, pollutant contamination, industrial estrogen exposure, and insect infestation (Chang and Davila 2008; Garcia et al 2001; Summy, Morales-Ramos, and King 1992; Wainwright et al 2001; White, Mitchell, and Kaiser 1983; White, Mitchell, Kennedy, et al 1983).…”

Charrettes are a useful tool to facilitate stakeholder discussion and generate useful end products to address regional issues. To identify regional environmental and sustainability issues, we held a series of interdisciplinary charrettes with stakeholders that shared a similar concern toward protecting the region. Outcomes included distinguishing exemplary sites representative of the issues on a base map and developing initial action items to address them. We present our lessons learned and provide recommendations to assist others in planning and implementing interdisciplinary charrettes.
