Abstract: Poboya River estuary
that known to have been contaminated with heavy metals, one of them is metal
lead (Pb). This is because the high human activity in the surrounding waters
hed, which may be the source of the entry of heavy metals into the estuary
waters. Poboya River estuary has many kinds of marine life, including fish such
as Belanak (Liza Melinoptera). Fish used as an indicator of contamination that
occurred in the waters. This study aims to determine how much accumulation and
metal concentrations of lead (Pb), which accumulates in fish living Belanak
Poboya estuaries. The method used is the gravimetric method for determining
water content, biomass and low ash content, while the analysis of the samples
in this study using Atomic Absorption Spectrometry instrument (SSA). The
results showed that the water content mobtained at 55.830%. While the levels of
biomass were obtained for 89.200% and ash content of meat samples obtained at
10.790%. While the results showed that the accumulation of the metal lead (Pb)
in Belanak fish average of 1.746 ± 1.673mg/kg. That exceeds the maximum value
of the metal Lead in food in accordance with ISO 01-2729.1-2006, ie 0.4 mg/kg.
