“…Contamination of soil and water by cadmium is connected with its uptake by plants -crops and vegetables -cultivated for human consumption (Jafarnejadi et al 2011;Khodaverdiloo et al 2011;Moustakas et al 2011;Romkens et al 2011). Smoking represents one of the most important sources of humans' exposure to cadmium (Satarug and Moore 2004;Massadeh et al 2010;Takeuchi et al 2010;Lin et al 2011). Numerous studies are focused on the formation of organic cadmium compounds by organisms, which are more toxic in comparison with inorganic forms, especially dimethyl derivatives (Yannai and Berdicevsky 1995).…”

The mustard family -Brassicaceae -is well known as family of plants, metallophytes, which are able to accumulate wide range of heavy metals and metalloids, especially zinc and cadmium, but also nickel, thallium, chromium and selenium. Ecological importance of this process consists partially in plants themselves to survive negative environmental conditions. There are two basic different strategies, how to survive these conditions -accumulation of heavy metals in plants tissues with different intensity in individual cell types, but also organs, which is partially given by chemical composition of cell walls, and ability to synthesize special defensive -detoxification compounds rich on thiol groupsglutathione and phytochelatins, which are able to bind heavy metals and transport them to the "secure" cell compartment -vacuole. The second principle is based on ability to exclude heavy metals. Role of secondary metabolites rich on sulphur in detoxification of heavy metals is still discussed with unclear conclusions. Members of Brassicaceae family, especially genera Thlaspi and Brassica, are well-known hyperaccumulators of heavy metals with possible utilization in phytoremediation technologies. In this review chapter, mechanisms of cadmium uptake and transport and its deposition in various plant cells and tissues are discussed with respect with

“…In the past few years human hair and fingernails have been recognised as an invaluable tissue and more attractive diagnostic tool in assessing heavy metals in human body with environmental exposure [20]. Nowadays there is an increasing interest of scalp hair and fingernails in the fields of medical, biological, forensic, and environmental sciences [17,18,[21][22][23], they can be easily sampled collected, stored and prepared for analysis [24,25].…”

The aim of this study was to determine selected heavy metal levels including cobalt (Co), Chromium (Cr) nickel (Ni) in scalp hair and fingernail samples of dental technicians. The scalp hair and fingernail samples were collected from 55 dental technicians and 25 medical technicians (control group). In the same time a questionnaire was filled by each subject of the two groups. The concentration of heavy metals (Co, Cr and Ni) in scalp hair and fingernail were determined by spectrometry. The result showed that the Co concentration in hair and nails of dental technicians was (0.74 µg/g, 6.5 µg/g respectively) compared with medical technicians (0.04 µg/g, 0.03 µg/g respectively). Ni concentration in hair and nails of dental technicians was (12.00 µg/g, 17.4 µg/g respectively) compared with medical technicians (6.3 µg/g, 6.00 µg/g respectively). Concentration of Cr in hair and nails of dental technicians was (9.37 µg/g, 10.6 µg/g respectively) compared with medical technicians (0.0 µg/g, 10.3 µg/g respectively), Ni was found to have the highest level in the hair and fingernails of dental technicians.

“…Each hair shaft is continuously in contact with the bloodstream at the hair root, and thus may incorporate elements circulating in the blood during growth. As a consequence, hair may reflect tissue element concentrations and serve as a good source for element analysis; it is an appropriate accumulative indicator of element bioavailability, with significant correlation between elements within hair and other tissues as well as environmental levels (McLean et al 2009;Massadeh et al 2011). It is therefore, a more reliable indicator of nutritional and clinical investigations.…”

This study was aimed to evaluate the comparative distribution, correlation and apportionment of selected elements (Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Pb and Zn) in the scalp hair of arthritis patients and healthy subjects. The hair samples collected from the patients (rheumatoid and osteoarthritis) and healthy donors were digested in nitric acid and perchloric acid mixture, followed by the quantification of trace elements using atomic absorption spectrometry. In the case of healthy donors, highest mean concentration was shown by Ca (3240 mg g À1 ), followed by Mg (340 mg g À1 ), Zn (192 mg g À1 ), Fe (184 mg g À1 ) and Pb (27 mg g À1 ), whereas, the estimated average metal levels in rheumatoid arthritis and osteoarthritis patients were 3160, 290, 197, 61 and 23 mg g À1 , and 3090, 300, 182, 50 and 21 mg g À1 , respectively. Most of the elements revealed diverse and random distribution in the scalp hair of the donor groups. The correlation study pointed out significant disparities in the mutual relationships among the trace elements in the patients and controls. Principal component analysis and cluster analysis of the element data manifested diverse apportionment of the selected elements in the scalp hair of the patients compared with the healthy counterparts.
