Fate of Heavy Metals Pb and Zn in the West Season at Jeneberang Estuary, Makassar
Abstract: The pollutant
quantity of heavy metals entering water environment does not give complete
answer toward the generated effect and risk, however it needs thoroughly study
related to the pollutant dynamic. The aim of this research was to investigate
the fate of Pb and Zn in water, such as: distribution, behavior, and reactivity
(case study: Jeneberang Estuary, Makassar). Pb and Zn concentrations were
determined using Atomic Absorption Spectrophotometry (AAS). The distribution of
dissolved Pb and Zn showed a pattern that the lowest concentration was in the
fresh water (the river zone), whereas the highest concentration was in the salt
water (the marine zone). The distribution pattern of particulate Pb and Zn
showed that the highest concentration was in the fresh water (the river zone)
and the salt water (the marine zone), whereas the lowest concentration was in
the estuary zone. The behavior of dissolved Pb and Zn tended to increase the
concentration (desorption) along the increased salinity gradient. The residual
fraction was the dominant component of geochemical fractions in the sediment that
indicated the sources of Pb and Zn mainly derived from a natural process and
the reactivity was low in the water.
