“…Hair mineral analysis has been used in forensic medicine, in screening populations for toxic metal poisoning, and in monitoring environmental pollutants [6,[12][13][14]. Furthermore, its clinical use has been tried for diagnosis of some diseases and symptoms [7,8], but reliability remained to be confirmed [15,16].…”

Objectives The objective of this metallomics study is to investigate comprehensively some relationships between cancer risk and minerals, including essential and toxic metals. Methods Twenty-four minerals including essential and toxic metals in scalp hair samples from 124 solid-cancer patients and 86 control subjects were measured with inductively coupled plasma mass spectrometry (ICP-MS), and the association of cancer with minerals was statistically analyzed with multiple logistic regression analysis. Results Multiple logistic regression analysis demonstrated that several minerals are significantly correlated to cancer, positively or inversely. The most cancer-correlated mineral was iodine (I) with the highest correlation coefficient of r = 0.301, followed by arsenic (As; r = 0.267), zinc (Zn; r = 0.261), and sodium (Na; r = 0.190), with p \ 0.01 for each case. In contrast, selenium (Se) was inversely correlated to cancer (r = -0.161, p \ 0.05), followed by vanadium (V) (r = -0.128). Multiple linear regression value was highly significantly correlated with probability of cancer (R 2 = 0.437, p \ 0.0001), and the area under the receiver-operating characteristic (ROC) curve was calculated to be 0.918. In addition, using contingency table analysis and the chi-square test, the precision of discrimination for cancer was estimated to be 0.871 (chi-square = 99.1, p \ 0.0001). Conclusions These findings suggest that some minerals such as arsenic, selenium, and probably iodine, zinc, sodium, and vanadium contribute to regulation of cancer and also that metallomics study using multiple logistic regression analysis is a useful tool for estimating cancer risk.

“…However, the fiber in the root during its growth is metabolically very active. This is mainly because of the certain advantages offered by hair over other clinical specimens such as blood or urine, namely; (i) the concentrations of most trace elements are higher in hair than other clinical specimens; (ii) the stability of hair, as a biological material, which facilitates the storage and transport processes; (iii) unlike other clinical samples, hair is inert and chemically homogeneous, and (iv) trace elements present in the body are incorporated into the hair during its growth [8][9][10]. Hair samples have been used for noninvasive diagnosis of cadmium toxicity in humans [11].…”

Abstract. This paper describes a new comparison and determination for demonstrating the levels of Al, Cd and Pb in cow's tail hair between Tehran as a polluted area and Semnan as an area free from pollution. The hair samples were collected from a total 227 apparently healthy lactating cows above 3 years of age. This includes 165 cows reared in industrial and urban area (Tehran) and 62 cows reared in area supposed to be free from pollution (Semnan). Prior to analysis, samples were washed with 0.1M HCl, acetone and deionized water. The hair samples were digested afterward in a mixture of nitric and perchloric acid mixture (HNO3:HCLO4=4:1 v/v). Concentrations of all metals were assessed by flame and graphite furnace atomic absorption spectrophotometer.

“…Just one study has addressed these issues during the last decade. It revealed (Batzevich, 1995) that it is not possible to associate ethnic differences with HSH trace element distribution because trace element concentrations are strongly influenced by nutritional and environmental factors.…”

Determination of inseparable exogenous and endogenous levels of toxic trace elements such as lead in human scalp hair has been used to understand and assess population exposure to such elements. For any such analysis, washing of the hair samples to remove superficial contamination is the foremost requirement. However, the use of such washing methods prior to elemental analysis removes minute quantities of trace elements from the hair strands. This degree of loss is dependent on the washing method employed. In the present study, the element lead has been determined in human scalp hair after three methods of hair washing. It is apparent that the nonionic detergent-acetone method is best suited for securing valid lead analysis results in human scalp hair.
