    KORELASI KANDUNGAN LOGAM BERAT (Pb DAN Cd PADA RAJUNGAN {Portunuspelagicus) DAN SEDIMEN DI PERAIRAN PANTAI DUMAI BARAT, RIAU
    (2015-02-27) AMNUR; ARIFIN
    sediment has been done in laboratory of material analyse of the engineering faculty. University of Riau, and laboratory of material testing of the settlement and facility authorization. Province of Riau in Mei 05 ^° Nov 05 This research aims to undestand heavy metals (Pb and Cd) correlation of rajungan and sediment. The applied method wus survai method, throughout Pb and Cd measurement by using Atomic Absorption Spectrofotometer (AAS). Analyse yield demonstrated Plumbum contents range at station I of rajungan flesh wus 3.437 PPM, sediment 9.753 PPiVI, through correlation value 0.42. At station II of rajungan flesh was 2.670 PPM, sediment 8.193 PPM through correlaton value -0.19, meanwhile at station III of rajungan flesh 3.587 PPM, sediment 7.567 PPM through correlation value 0.19. Cadmium concent range at station I of rajungan flesh was 3.899 PPM, sediment 5.546 PPM through correlation value 0.27. At station II of rajungan flesh was 4.482 PPM, sediment 5.416 PPM through correlation value 0.62, meanwhile at station III of rajungan flesh was 4.743 PPM, sediment 7.562 PPM through correlation -A)AO. No correlation of heavy metal (Pb and Cd) content of rajungan and sediment.
