Comments From Research Reports

Several research programs for studying and establishing hair trace mineral concentrations have been implemented since 1965 by the International Atomic Energy Agency. These research programs have been coordinated under “Nuclear-based Methods for the Analysis of Pollutants in Human Hair.” Hair was chosen by the I.A.E.A. due to the concentration of minerals in the hair and its reflection of both external and internal contamination. The bulk of data on trace element concentrations has been reported from hair samples obtained from the scalp.

Bioassay of hair is attractive as it is an effective bio-concentrator, samples can be easily stored, the concentration reflects an integrated value, and, finally, the measurement of the (234)U/(238)U isotopic ratio in digested hair samples by MC-ICPMS is feasible and highly informative.Karpas Z, Lorber A, Sela H, Paz-Tal O, Hagag Y, Kurttio P, Salonen L., Measurement of the 234U/238U ratio by MC-ICPMS in drinking water, hair, nails, and urine as an indicator of uranium exposure source. Health Phys. 2005 Oct;89(4):315-21.

Human head hair is a recording filament that can reflect metabolic changes of many elements over long periods of time and thus furnish a print-out of post nutritional events.Strain, W. H.; Pories, W. J.; Flynn, A.; Hill, O. A.: Trace Element Nutriture and Metabolism Through Head Hair Analysis. Trace Substances in Environmental Health. Hemphill, D. D., ed. University of Missouri Press, Columbia, 1972.

It is well known that nutritional mineral deficiency can impair neurological development. Some transitional nutrients can cause later-life health disturbances when deficient in the diet, but in excess can be just as harmful and include iron, copper, manganese, zinc and others. Heavy metals such as lead, cadmium, mercury and arsenic are also neurotoxins and when present early in life can contribute to impaired neuro-development and detrimental health effects later in life and have been called the fetal origins of disease. Hair concentrations of cadmium compared to reference groups were found to be higher in children with mental retardation, learning disabilities, dyslexia and lower I.Q.Metals and Neurotoxicology. Wright, RO, et al. J. Of Nutr. 138,12, 2007.

Hair, blood and urine minerals analyzed in diabetic patients compared to non-diabetic controls showed that the mean levels of zinc, manganese and chromium were significantly lower in the blood and scalp hair of patients diagnosed with diabetes. Higher levels of copper and iron were also found in the scalp hair of the diabetic group as well.Copper, Chromium, Manganese, Iron, Nickel and Zinc Levels in Biological Samples of Diabetes Mellitus Patients. Kazi, TS, et al. Biol. Trace Elem. Res. 122,1, 2008.

Statistical evaluation of these data by multi variant analysis (MANOVA) using a contrast matrix and by discriminant analysis showed that elemental hair anomalies can be used to diagnose correctly the above-mentioned pathologies, demonstrating the usefulness of hair analysis as a complementary tool for the detection of disturbances in calcium/bone metabolism.Miekeley, N., et al. Elemental Anomalies in Hair as Indicators of Endocrinologic Pathologies and Deficiencies in Calcium and Bone Metabolism., J. Trace Elem. Med. Biol. 15, 1, 2005

The consensus of most workers in the field is that if hair samples are collected properly, cleaned and prepared for analysis correctly and analyzed by the best analytical methods, using standards and blanks as required, in a clean and reliable laboratory, by experienced personnel, the data are reliable.Toxic Trace Metals in Mammalian Hair and Nails. United States Environmental Protection Agency Publication 1979; EPA-600/4: 79: 049

A study of men over a period of thirteen years found that for each microgram of mercury found in the hair, the risk of acute coronary events increased by an average of eleven percent and cardiovascular disease death rate by ten percent.Mercury as a Risk Factor for Cardiovascular Disease. J. Nutr. Biochem. 18, 2007.

An example of how mineral intake is reflected in the hair was demonstrated in a study of several thousand Iraqi peasants, whose diet contained grain heavily treated with fungicides. The fungicides contained organic mercury, which was reflected in higher concentrations in the hair when consumption was highest and decreased when consumption was lowest. Hair concentrations correlated directly with the extent of symptoms.Al-Shahristani, H.; Al-Haddad, I. K.: Mercury Content of Hair From Normal and Poisoned Persons. J Radioanalytical Chem 1973; 15. Al-Shahristani, H.; Shihab, K. M.: Variation of Biological Half-Life of Methylmercury in Man. Arch Environ Health 1974; 28.

Hair samples collected and analyzed from five countries with known arsenic sources, both high and low included the United States, Canada, and People’s Republic of China, Bangladesh and Nepal. Hair arsenic concentration in all hair samples correlated with the amount of arsenic in drinking water and revealed the low intake of selenium in areas of high arsenic concentrations. The results demonstrate the viability of hair as a noninvasive biomonitor in assessing aspects of dietary Se and environmental As exposure.Spallholz JE, Boylan LM, Palace V, Chen J, Smith L, Rahman MM, Robertson JD., Arsenic and Selenium in Human Hair; A comparison of Five Countries With and Without Arsenicosis., Biol Trace Elem Res. 2005 Aug;106(2):133-44.

The proliferation of trace element analysis as a tool for biological investigation of nutrition, growth and development, and disease processes has led to consideration of (hair) trace element analysis as a means not only of present evaluation and estimation, but also as a technique for the reconstruction of past biological events in an organism.Gilbert, R. I.: Trace Elements in Human Hair and Bone. Hair, Trace Elements and Human Illness Brown, A.C.; Crounse, R. G. ed. Praeger Publications, 1980.

This study was performed to establish a relationship between elements in the serum, red cells and hair and included one hundred and seventy-four children. Tests measured the concentrations of the heavy metals, cadmium and lead, as well as calcium, magnesium, copper, zinc and iron. Serum and red blood cell concentrations of cadmium and lead were within normal allowable levels, but hair levels exceeded maximum levels. Supplementation of magnesium and vitamin B6 was begun in children with elevated hair heavy metals. Follow-up tests showed a marked reduction in the lead and cadmium concentration in the hair and erythrocytes.Concentrations of Selected Bioelements and Toxic Metals and Their Influence on Health Status of Children and Youth Residing in Szczecin. Kedzierska, E. Ann. Acad. Med. Stetin. 49, 2003.

The significance of hair analysis as a biological indicator of abnormal intake of trace elements in man is confirmed. Geographical variations of hair trace element concentrations, on the whole, depend on geochemical conditions or nutritional factors.Batzevich VA., Hair trace element analysis in human ecology studies., Sci Total Environ. 1995 Mar 15;164(2):89-98.

The result of research studies indicate that hair mineral analysis can be useful as a diagnostic tool in the examination of trace metal exposure, including abnormal nutritional intake, and may assist in the study of certain mental states. They (hair mineral analysis) may suggest mineral imbalances present in the body that perhaps could be rectified by a mineral supplemented diet. Hair metal testing is a fascinating new diagnostic tool and often gives unexpected clues to mineral imbalances in the body. The authors would support this statement from the results that they have accumulated to date.Barlow, P. J.; Kapel, M.: Metal and Sulfur Contents of Hair in Relation to Certain Mental States. Hair, Trace Elements, and Human Illness Brown, A.C.; Crounse, R. G., eds. Praeger Publications, 1980.

By implementation of statistic pattern recognition methods, it has been found that the concentrations of trace elements in hair can remarkably reflect different recovery phases of NPC patients.Leung PL, Huang HM., Following the recovery of naso-pharyngeal cancer patients by trace elements in hair using statistical pattern recognition methods., Biol Trace Elem Res. 1998 Jun;62(3):235-53.

We suggest that the changed element status (Zn, Mg, and Cu) in hair may play an indicator role in the diagnosis of epileptic patients.Ilhan A, Uz E, Kali S, Var A, Akyol O., Serum and hair trace element levels in patients with epilepsy and healthy subjects: does the antiepileptic therapy affect the element concentrations of hair?, Eur J Neurol. 1999 Nov;6(6):705-9.

Mercury, cadmium and other heavy metals have a high affinity for sulfhydryl groups, inactivating enzymatic reactions, amino acids, and sulfur-containing antioxidants. Cadmium concentrations in the kidney induce renal dysfunction and contribute to hypertension due to sodium retention, glucose intolerance, dyslipidemia and zinc deficiency. Heavy metal toxicity should be evaluated in any patient with hypertension, cardiovascular heart disease, or other vascular disease. Specific testing for acute and chronic toxicity and total body burden using hair, nail, urine and serum with baseline and provoked evaluation should be done.The Role of Mercury and Cadmium Heavy Metals In Vascular Disease, Hypertension, Coronary Heart Disease and Myocardial Infarction. Houston, MC. Altern. Ther. Health Med. 13,2,2007.

Various changes in the content of trace elements in biological samples taken from patients with idiopathic scoliosis are not accidental.

Hair mineral analysis was performed on over three-hundred adult females with BMI’s ranging between low, normal and high. Significant differences were noted in zinc levels between women with a low BMI compared to those with a high BMI. The obese group had the lowest zinc levels as well as the lowest ratios of sodium/potassium, iron/copper and zinc/copper. ..we suggest that hair concentrations of Ca, Cu, Fe, Mg, K, Na and Zn may be correlated with adult female BMI, but further studies are needed.Wang, CT, et al., Concentrations of Calcium, Copper, Iron, Magnesium, Potassium, Sodium and Zinc in Adult Females hair with Different Body Mass Indexes in Taiwan., Clin. Chem. Lab. Med. 43, 4, 2005

Hair tissue mineral analysis was performed on one-hundred and twenty individuals. Supplementation of magnesium and vitamin B6 was implemented in the treatment groups and placebos in the control group. Repeat hair mineral analysis revealed a positive influence as a result of supplementation. Magnesium levels were increased in the hair along with a significant reduction of the heavy metals, lead and cadmium. The above mentioned results indicate a positive influence of magnesium supplementation on the decrease of lead and cadmium hair content in the individuals studied.Kozielec T, Salacka A, Karakiewicz B., The influence of magnesium supplementation on concentrations of chosen bioelements and toxic metals in adult human hair. Magnesium and chosen bioelements in hair., Magnes Res. 2004 Sep;17(3):183-8.

From the analyses, it was clear that hair concentrations of Ca, Fe, and Zn could reflect the effects of supplementation.Leung PL, Huang HM, Sun DZ, Zhu MG., Hair concentrations of calcium, iron, and zinc in pregnant women and effects of supplementation., Biol Trace Elem Res. 1999 Sep;69(3):269-82.

One such procedure which has shown great potential, at least for the determination of micro-element nutriture…, is the use of hair as the biological sample. Perhaps an even more important advantage would be that hair, by the very nature of the sample, should reflect a rather long-term nutritional state rather than recent (i.e. previous meal or day) dietary intake.Sauberlich, H. E.; Scala, J. H. Department of Nutrition, Letterman Army Institute of Research, San Francisco, California. Dowdy, R. P.

Lorenzo, A, et al. J. Trace Elem. Med. Biol. 19,1, 2005.

Changes in the hair iron concentrations were accompanied by similar changes in the concentrations of the markers most commonly used to diagnose and monitor iron deficiency. The results suggest that quantification of hair iron may be useful to complement evaluations of the body iron status.Bisse E, Renner F, Sussmann S, Scholmerich J, Wieland H., Hair iron content: possible marker to complement monitoring therapy of iron deficiency in patients with chronic inflammatory bowel diseases?, Clin Chem. 1996 Aug;42(8 Pt 1):1270-4.

Hair calcium concentration did reflect the risk of CHD on a population basis and was strongly influenced by both the hardness of the water supply and the annual sunshine hours which also independently affected the SMR for CHD.MacPherson A, Bacso J., Relationship of hair calcium concentration to incidence of coronary heart disease., Sci Total Environ. 2000 Jun 8;255(1-3):11-9.
