Twenty Henna samples were collected and analysed for lead by electrothermal atomic absorption spectrophotometry after a microwave acid digestion procedure. The mean lead concentration was 5.50 p.g g-l, with a range from 1.29 I.tg g-1 to 16.48 lxg g-~. The data did not show a high concentration of le

โฆ Synopsis
Lead was determined in whole blood samples obtained from 202 Saudi male volunteers. The influence of smoking on lead exposure was investigated. Blood lead was significantly higher in current smokers than in non-smokers and previous smokers (P < 0.05). The distribution of blood lead data in the screened subjects suggested the eixstence of two mixed populations and a cut-off of 12/lg dl-i was found where the two populations separate. Of the exposed population, 80% with blood lead concentrations above 12/~g dl-J were smokers.
