Ia. Alsaleh et L. Coate, LEAD-EXPOSURE IN SAUDI-ARABIA FROM THE USE OF TRADITIONAL COSMETICS AND MEDICAL REMEDIES, Environmental geochemistry and health, 17(1), 1995, pp. 29-31
Twenty Henna samples were collected and analysed for lead by electroth
ermal atomic absorption spectrophotometry after a microwave acid diges
tion procedure. The mean lead concentration was 5.50 mu g g(-1), with
a range from 1.29 mu g (g-1) to 16.48 mu g g(-1). The data did not sho
w a high concentration of lead in these samples. However, if we take i
nto account the popular use of henna, the cumulative effects of prolon
ged exposure to low lead especially in children cannot be ruled out.
