KONSENTRASI LOGAM BERAT DI PERAIRAN, SEDIMEN DAN BIOTA DENGAN FAKTOR BIOKONSENTRASINYA DI PERAIRAN BATU BELUBANG, KAB. BANGKA TENGAH
Abstract: The reduction of
land that used for land-based mining caused the shift of mining from land-based
mining to off-shore mining, that used to namedFloating Inkonvensional Mining.
This type of mining caused waters quality degradation.This research aimed to analyze
Pb, Cd, and Zn content in water, sediment, and biota so that the value of the
bio-accumulation factor can beanalyzed.The locations determination was
conducted by using purposive random sampling method and the implementation was
using GPS Garmin 60 in June 2013. The sea water sampling was using the water
sampler, the sediment sampling was using paralon pipe, the plankton sampling
was using the plankton-net, the shellfishes sample was collected from the
fishermen, and the chavies and squids sample was got from Baganin the waters of
Pulau Panjang.The analysis of the metal in water and sediment was refer to the
prosedur standard method (APHA, 2005), while the analysis of the heavy metal in
the planktons and the tissue of the biota was refer to SNI 2354.5:2011. The
content of metal was compared with the quality standard that have been
determined.The Cd and Zn content in water was under the sea water quality
standard for sea biota. The Pb in the waters have been exceeded the quality
standard that have been determined in Kepmen LH no. 51 Tahun 2004.The Pb, Cd,
and Zn content in sediment was lower and
far away from the quality sandard that have been determined by Norwegia and
Irlandia. The heavy metal content in Anadara granosa, Stolephorus, sp, and
Loligo chinensis, gray which were got chaught in the waters of Batu Belubang
was lower thanthe national quality standard (SNI 2731.1:2010). The value of
bio-concentration factor (BCFs-w) showed that the highest ability of sediment
to accumulate Pb was existed in station number 2, i.e. 10,037 l/kg. The value
of bio-concentration factor (BCFo-s) showed the plankton ability to accumulate
Pb in sediment (1,26) was higher than its ability to accumulate Zn in sediment
(1,22), while its ability to accumulate metal in water (BCFo-w) was as high as
8,275 in station number 2. The value of bio-concentration factor (BCFo-s)
showed that the shellfish, chavies, and squid ability in accumulating metal in
sediment was as high as 0,713; 0,564 and 0,703. The value of bio-accumulation
of shellfish in sediment was higher because sediment was the habitat of
shellfish.Floating Inkonvensional Mininghave contribution in spreading heavy
metal, that was contained in the soil, to the waters. This condition needs
supervision to control TI Apung growth in this location so that does not
pollute the waters.
