“…Hammer ct al. (1972), Petering et al (1973), Klevay (1973), Orheim et al (1974) and Dorn et al (1974) reported significant correlations between Cd, Pb and As contents of human and animal hair and exposure of humans and animals to these elements. Hammer et al (1972), Klevay (1973) and Petering et al (1973) emphasized, however, that the extent to which hair predicts environmental exposure to heavy metals depends on factors such as age, sex, length of hair and chemical treatment of hair.…”

“…Hammer et al (1972) and Petering et al (1973) reported that significant correlations existed between Cd content of human hair and exposure to Cd. Dorn et al (1974) examined Cd content of hair from cattle grazing on a farm located within 800 m of a Pb smelter and compared them with Cd content in hair from cattle grazing on a farm that was free of industrial Cd exposure. The authors found significantly higher Cd levels in hair of cattle on the farm located near the smelter than in hair of cattle on the control farm.…”

“…Hammer et al (1971Hammer et al ( , 1972, Petering et al (1973) and Klevay (1973) reported that humans have hair Pb levels that corresponded to environmental Pb exposure. Dorn et al (1974) reported that cows grazing within 800 m of a Pb smelter had higher concentrations of Pb in their hair than cows grazing on a farm that was free of Pb exposure. It appears that the major source of Pb in the hair of cows grazing near the smelter was exogenous contamination.…”

Mineral content of hair is affected by season, breed, hair color within and between breeds, sire, age and body location. Seasonal effects may be due to stage of growth of hair and to changes caused by perspiration, surface contamination and diet. Breed and sire effects on mineral content of hair complicate prediction of nutritional status based on hair analyses because, in many commercial cattle, neither breed nor sire is known. Hair from young animals may be lower in Zn, Mn and Fe, but is higher in Na, Ca, Cu and K than that from older animals. Pigmented hair apparently is higher in Ca, Mg, K and NA than white hair, but trace mineral concentrations are similar in hair of different colors. The effect of body location on mineral content of hair may be due to differences in surface contamination, differences in hair growth cycles and differences in texture of the hair. Concentrations of Ca, P and Cu in hair are not affected by dietary intake of these minerals. Zn and Se contents of hair may reflect dietary intake. Information on other required minerals in lacking. Pb, As and, possibly, Cd levels in hair may be related to dietary or environmental exposure. Because of the many factors that cause variation in mineral content of hair, hair analyses are not likely to be precise indicators of the mineral status of animals. Hair analyses may help to detect severe deficiencies of some required minerals or exposure to some heavy metals. However, if hair analyses are to be conducted, care must be taken to compare values from test animals with those from animals of similar breed, sex, season, sire and color. In addition, new hair growth should be analyzed, environmental contamination should be minimized and the hair samples should be cleaned before analyses.

“…Significant correlations (p = 0.01) between hair and liver concentrations of cattle were found by Russell and Schoberl (1970). Dorn et al (1974) found one to two orders of magnitude increase in lead concentrations in hair of cows exposed to industrial pollution when compared to controls.…”
