EVALUATION OF TOTAL MERCURY IN SCALP HAIR SAMPLES OF LIBYAN FISHERMENIntisar Alakeili, Aiman. M. Bobaker and S.B. Sarmani
To evaluate the concentration of total mercury (T-Hg) in Libyan fishermen 40 scalp hair samples were collected from the fishermen and analysed by neutron activation analysis. The results show that the mean (Â±standard deviation) of T-Hg in hair of anticipates fishermen was 5.25Â±1.81 Î¼g/g in the range of 1.34 to 8.93 Î¼g/g. In term of comparison, 15 scalp hair samples from non-fish eaters (control group) were collected and analysed for total mercury. The results show that, the mean (Â± standard deviation) concentration of THg in their hair samples was 1.71 Â± 0.90 Î¼g/g in the range of 0.65 to 4.01 Î¼g/g. The difference between the two groups was significant. The influence of fish consumption, age, weight, dental amalgam and smoking were also investigated.
