title: Mercury determination in hair of Malaysian fishermen by neutron activation analysis.
abstract: Fish has been known as a source of nonoccupational mercury exposure to fish-consuming population groups. In this study, hair samples collected from fishermen and their families residing in an industrialized area in Penang and a nonindustrialized area in Terengganu were analyzed for mercury by neutron activation. The range, arithmetic mean, geometric mean, and median of the mercury concentrations for the groups in Penang and in Terengganu were 0.45-16.68, 3.61, 3.49, and 2.96 and 6.79-18.31, 12.08, 11.69, and 12.05 mg/kg, respectively. Somewhat lower values than from the Penang group were found in a group from Selangor consisting mainly of office workers. The group in Penang took about 40-100 g of fish/d, whereas the group in Terengganu consumed twice as much. This shows that hair mercury levels depend on a fish consumption pattern, and not on the location of the population. The levels of mercury found in this study were similar to those reported by other workers for fish-consuming population groups worldwide.
