| Abstract: | The concentrations of the elements copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) in hair of caged (in Maryland) and
freeranging (in Puerto Rico) rhesus monkey populations were determined. Significant chronological age-related decreases were
evident for the trace elements Mn and Zn in both populations (P<0.01) and for Cu and Fe in free-ranging monkeys (P<0.005). The only overall gender difference was higher hair Mn concentration in freeranging males than in females (P<0.03). There were no significant differences in hair Cu, Fe, or Mn related to pregnancy status. Hair Zn was lower in samples
from pregnant than from nonpregnant monkeys from the caged monkeys (P≤0.05), but did not differe in the freeranging monkeys. Comparison of the two populations revealed that hair Zn levels were
significantly higher in caged vs free-ranging animals (P<0.001). We attribute this higher hair Zn in the caged monkeys to contact and ingestion of Zn from their galvanized enclosures.
Hair iron levels were significantly higher (P<0.001) in free-ranging monkeys, possibly as a result of Fe-rich soil ingestion from their environment. These data support
continued investigation of the use of hair as an indicator of the exposure of large groups or populations to potentially high
levels of specific minerals, and the use of nonhuman primates as models for the study of trace element deficiency and/or toxicity
in humans.
Prelliminary reports of portions of these data were presented at the 69th Annual Meeting of the Federation of American Societies
for Experimental Biology, April 1982, New Orleans, LA (B. M. Marriott, J. C. Smith, R. Jacobs, A. O. Jones, M. J. Kessler,
and R. Rawlins,Fed. Proc. 41:770, 1982]) and in a symposium at the 6th Annual Meeting of the American Society of Primatologists, 1983, East Lansing,
MI (B. Marriott, J. C. Smith, R. Jacobs, A. O. Lee Jones, R. Rawlins, and M. J. Kessler,Am. J. Primatol. 4(3): 157 1983]; B. Marriott, J. C. Smith, Jr., R. M. Jacobs, A. O. Lee Jones, R.
