Abstract

The concentration analysis of heavy metals: Cd, Cr, Cu, Hg and Pb in the biota in the Kalisari, Wonokromo and Wonorejo rivers anu the sea around the river's of East Surabaya Shore (PAMURBA Y A) using Grab sampling have already done. The samples biota preparations using digestion method using concentrated HN03 and H20 2• In the Kalisari river, the researchers could not find the biota, while in the sea around estuary, the researchers found Yoldia Iucida with concentrations of Cd, Cr, Cu, Hg and Pb are: 0.881 ± 0.0646; 1.644 ± 0.0101; 10.130 ± 0.0172; 23.783 ± 0.0277 and 2.506 ± 0.0144 ug/g, also Anadara granosa with concentrations of Cu and Hg are: 0.849 ± 0.0032 and 12.931 ± 0.0020 ug/g. On the resaerch in Wonokromo river, the researchers found Tel/ina alternata with concentrations of Cd, Cu, Hg and Pb are: 0.713 ± 0.0006; 1.335 ± 0.0079; 7.668 ± 0.0001 and 0.853 ± 0.0006 ug/g also Meretrix meretrix with concentrations of Cd, Cr, Cu, Hg and Pb are: 2.923 ± 0.0022; 1.349 ± 0.0079; 10.369 ± 0.0143; 19.090 ± 0.0164 and 3.573 ± 0.0097 ug/g. In the sea around estuary of this river, the researchers found Anadara granosa with concentrations of Cu and Hg are: 0.524 ± 0.0035 and 44.3 10 ± 0.0334 ug/g, also Corbula contracta with concentrations of Cr, Cu and Hg are: 0.360 ± 0.0027; 1.814 ± 0.0097; 9.934 ± 0.0 I 31 ug/g and Meretrix meretrix with concentrations of Cr, Cu, Hg and Pb are 2.245 ± 0.0050; 2.812 ± 0.0057; 22.498 ± 0.0147 and 2.849 ± 0.1790 ug/g dry weight samples respectively. In the Wonorejo river and the sea around estuary, the researchers could not fmd biota. The tolerance limit for Cd was 400-500 ug/person/week, Cr was 35 ug/day, Cu was 10 ug/day/woman or 12 ug/day/man and Pb was 3 mglpersonlweek, while concentration of Hg was not tolerated .
