Abstract
The
objectives of this study were to measure the levels of lead, cadmium, and
mercury in the muscle tissues of halfbeaks (Hyporhampus affinis) captured at
five stations along the East Java coast, Indonesia. This fish is one of the
important species and consumed by local people as a cheap source of protein. We
evaluated the hazard level posed by the metals in relation to the maximum
residual limit for human consumption and to estimate the weekly intake and
compare it with the provisional tolerable weekly intake (PTWI). The Pb, Cd, and
Hg concentrations in fish at all stations ranged from 0.006 to 0.023 mg/kg,
0.007 to 0.024 mg/kg, and 0.047 to 0.055 mg/kg wet weight, respectively. All
samples of halfbeaks collected from this area appear to be safe for human
consumption because their metals' levels are below the permissible limit for
human consumption and the maximum weekly intakes are below the recommended
values of PTWI. © 2013 Copyright Taylor and Francis Group, LLC.
