“The neurotoxicity of methylmercury in children exposed in utero has been determined to be the critical effect for the human RfD. Maternal hair mercury concentrations predict mercury concentrations in fetal brain (Cernichiari et al., 1995), fetal blood (Cernichiari et al., 1995), umbilical cord blood (Wheatley and Paradis, 1995; Girard and Dumont, 1995), and newborn hair (Chai et al.,1994).”
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.

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.

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.

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.”

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.

“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.”

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.

“As new chemicals enter commerce, the number of chemicals on the Inventory changes. Today more than 84,000 chemical substances are on the Inventory.”
The initial reporting period was January to May of 1978, for chemical substances that had been in commerce since January of 1975. The initial TSCA Inventory, published in 1979, was followed by a second version in 1982, which included approximately 62,000 chemical substances.
“Chemicals are part of life in the 21st century and are found in nearly everything we use. Some 70,000 different chemicals are available on the market today and around 1,500 new ones are introduced every year. Estimates indicate that at least 30,000 chemicals on the market have never been subject to comprehensive testing on any risks to humans, and that appropriate testing of risks during their developmental stages was not included in standard testing. Furthermore, there is little information on which population groups are being exposed to which chemicals, at what doses, and what the exposure means to health. “

“Using the definitions above, each category was enumerated using data first from the FDA, then from regulatory agencies outside the US. In this step, inclusion and completeness was the goal, with redundancy to be eliminated later (see following section). Lists of drug names approved for human use were obtained from the FDA official publications including the Orange Book, the National Drug Code (NDC), the Drugs@FDA webpage, the Over-the-Counter (OTC) listings from the Office of Nonprescription Products, and its Substance Registration System’s Unique Ingredient Identifier (UNII). After assigning structures and Chemical Abstracts Service (CAS) numbers to these names wherever applicable and removing duplicate entries, we found that FDA has over 100,000 Drug Products registered. These Drug Products have in them over 10,000 Drugs. However, this latter number, though formally correct, is misleading since the majority of these 10,000 are different brands of the same API, different APIs of the same ME, or chemically undefined substances (e.g. allergenic extracts)”

“There is substantial evidence from animal and man demonstrating that both transient and more long-term epigenetic mechanisms have a role in the regulation of the molecular events governing adipogenesis and glucose homeostasis. Intrauterine exposure such as poor maternal nutrition has consistently been demonstrated to contribute to a particular epigenotype and thereby developmental metabolic priming of the exposed offspring in animal and man.”

“Maternal gestational glucose concentration was significantly associated with offspring insulin sensitivity and β-cell response independent of adiposity. These results suggest that maternal glucose may program the fetus both at the pancreas and at the level of insulin target tissues such as skeletal muscle and liver.”

“Pathways of core metabolism can then be separated conveniently into three classes: those that synthesize simple molecules or polymerize them into more complex macromolecules (anabolism); those that degrade molecules to release energy (catabolism); and those that help eliminate the toxic waste produced by the other classes (waste disposal). These pathways are profoundly important. Stated bluntly, they are the sole source of energy that allows life to resist the urge to degrade into entropy.”
