“…In this case, the largest share in these relationships is ascribed to the hair and liver, as well as to the hair and kidneys. This may indicate that the hair is a good matrix for the initial assessment of animal exposure to various metals, which was confirmed, among others, by Cygan-Szczegielniak et al [ 5 , 13 ] and other authors [ 3 , 14 ]. Moreover, the hair may be collected from the animal in vivo, which in some cases is of great importance.…”

“…The exception was the hair of red deer, in which Cd concentration was 50% lower (0.13 mg·kg −1 of d.w.) than in muscles of fallow deer. Animal hair is certainly one of the most important matrices that can be used as a bioindicator of trace elements in the environment [ 5 , 13 ], as with human hair [ 14 ]. The content of individual macro- and microelements as well as Pb and Cd in the hair of red deer was comparable to the content measured in the same matrix from red deer in the season before the present study [ 5 ].…”

“…Some plants tend to accumulate more pollutants [ 10 ] of which the consumption by an animal is a source of direct exposure to these compounds and their increased accumulation in animal tissues [ 7 ]. Toxic elements can accumulate in hard tissues, such as bones, teeth [ 7 , 8 ] and antlers [ 9 ], in hair [ 3 , 5 , 13 , 14 ] and in the parenchymal organs, such as the liver [ 4 , 15 , 16 ], muscles [ 6 , 17 ] and kidneys [ 4 , 18 ]. Red deer living in a given area have different access to essential trace elements and toxic elements, which is reflected in their different concentration in animal tissues [ 11 ].…”

The aim of the study was to analyse correlations and variability between the levels of mineral elements (Fe, Mn, Zn, Cu, Na, K, Ca and Mg) and toxic metals (Pb and Cd) in the longissimus lumborum muscle, hair and selected organs of red deer (Cervus elaphus L.). The levels of mineral elements were measured using atomic absorption spectroscopy (F-AAS). The levels of Pb and Cd were analysed by means of electrothermal atomic absorption spectroscopy (ET-AAS). Of all analysed microelements, the highest concentration (in g·kg−1 of dry weight) was found for Fe in the liver. Considering all macroelements, the highest level was found for K in the longissimus lumborum muscle. Particularly remarkable was the high level of Pb in the muscle and hair of red deer. The level of Cd in the hair was four to five times lower than in other samples. The study revealed many significant correlations between the levels of certain elements in individual tissues and organs. There were significant correlations between Cu-Fe (rxy = 0.650; p ≤ 0.01), Pb-Cu (rxy = −0.863; p ≤ 0.01) and Cd-Ca (rxy = −0.743; p ≤ 0.01) in testicles. For kidneys, a significant negative correlation was found for K and Na (rxy = −0.779; p ≤ 0.01) and for Ca and Cd (rxy = −0.695; p ≤ 0.01), and a positive correlation between Cu and Mn (rxy = 0.693; p ≤ 0.01). In the liver, significant negative correlations were found between Ca-K (rxy = −0.654; p ≤ 0.05), Cd-Fe (rxy = −0.651; p ≤ 0.05) and Pb-Cu (rxy = −0.627; p ≤ 0.05). In the muscle, only single significant correlations were found between Cd and Mn (rxy = 0.648; p ≤ 0.05). The highest number of significant correlations were recorded for the hair, among others between Na-K (rxy = 0.760) and Ca-Zn (rxy = 0.709) at p ≤ 0.01. The study revealed high variability in the levels of mineral elements and selected toxic metals in tissues, organs and hair of red deer. Additionally, this research confirmed that the accumulation of a specific metal in a tissue or organ can reduce its concentration in another matrix or promote its increased content in another tissue or organ.

“…The rationale for investigating elementary composition in the brain is diverse. The excellent sensitivity and specificity achievable with fluorescence x-ray microscopy (XRM) allow for the investigation of metal toxicity, for example, from environmental exposure to heavy metals (Md Khudzari et al, 2013). Some studies have also used this technique to investigate the normally functioning brain and disease-mediated changes due to the storage and metabolism of biologically essential metal elements in specific intracellular compartments or as widespread accumulation in the brain.…”

Illuminating the Brain With X-Rays: Contributions and Future Perspectives of High-Resolution Microtomography to Neuroscience

The assessment of three-dimensional (3D) brain cytoarchitecture at a cellular resolution remains a great challenge in the field of neuroscience and constant development of imaging techniques has become crucial, particularly when it comes to offering direct and clear obtention of data from macro to nano scales. Magnetic resonance imaging (MRI) and electron or optical microscopy, although valuable, still face some issues such as the lack of contrast and extensive sample preparation protocols. In this context, x-ray microtomography (μCT) has become a promising non-destructive tool for imaging a broad range of samples, from dense materials to soft biological specimens. It is a new supplemental method to be explored for deciphering the cytoarchitecture and connectivity of the brain. This review aims to bring together published works using x-ray μCT in neurobiology in order to discuss the achievements made so far and the future of this technique for neuroscience.

“…As working in the open air, sanitation workers are also suffered from rain, snow, sand, cold and ultraviolet rays. These factors lead to harmful effects on the overall health of the sanitation workers, including skin 2 , hair 3 , respiratory 4 , gastrointestinal 5 , urogenital 2 , as well as orthopedic problems 6 . Skin serves as a natural barrier from pathogens and damage between the internal and external environment in body defense, and is predisposed to disease when subjected to environmental stressors.…”

Background: Little research has been focused on the health status or the occupational protection awareness of sanitation workers. The policy recommendations on the occupational safety and health of sanitation workers based on the scientific research are also insufficient in developing countries like China. Objective: To study the incidence of dermatoses and the relevance with occupational exposure, protection awareness and protective measures among sanitation workers for better management and protection of the sanitation workers. Methods: 273 sanitation workers and 113 administrative staff from 11 streets of Wuhan were recruited. Dermatological problems were evaluated and recorded by physical examination. Occupational exposure, protection awareness, the use of protective equipments and personal history of skin disease were assessed by questionnaires. Results: Compared with administrative staff, sanitation workers had much more occupational dermatological problems and had a much higher rate of harmful ultraviolet ray exposure. Young sanitation workers were more aware of occupational self-protection and a relatively higher rate of them using protective equipments compared with old ones. Conclusion: Exposure to multiple health hazards and the poor use of protective equipments are related to skin diseases in sanitation workers. Prejob training of self-protection and the use of protective equipments are recommended.
