Penelitian Lingkungan dan Kebencanaan Geologi Kelautan Perairan Teluk Jakarta (Tanjung Kait – Muara Gembong) dilakukan pada bulan Oktober - November 2010. Uji logam berat (Cu, Pb, Zn, Cd, dan Cr) dilakukan terhadap 28 contoh air laut dan 28 contoh sedimen dasar laut menggunakan metoda Atomic Absorption Spectrophotometry (AAS). Tujuan penelitian ini adalah untuk mendapatkan data dan informasi kondisi lingkungan terkini dari kandungan logam berat dalam air laut dan sedimen dasar laut. Kandungan logam berat (air laut dalam mg/l : sedimen dasar laut dalam ppm) terukur sebagai berikut : Cu ( <0.005 : 15.000-169.500 ); Pb (0.005-0.011 : 14.000-58.100); Zn (0.005-0.007 : 95.800-333.000); Cd (0.006-0.015 : 0.012-0.750); Cr (<0.001 : 45.320-139.180). Berdasarkan Metode Storet dapat dilihat nilai status mutu air laut perairan ini adalah -12, berarti bahwa kualitas air laut di perairan termasuk kelas C (tercemar sedang). Sedangkan status mutu sedimen di perairan menunjukkan skor nilai status mutu sedimen adalah 0, yang berarti bahwa kualitas sedimen termasuk kelas A (tidak tercemar/memenuhi baku mutu). Jelas terlihat bahwa nilai ambang batas (NAB) logam berat dalam sedimen jauh lebih tinggi dari NAB logam berat dalam air. Kata kunci: logam berat, sedimen dasar laut, air laut, nilai status mutu Marine Environmental and Geological Hazard Survey In Jakarta Bay Waters (Tanjung Kait - Muara Gembong) conducted in October-November 2010. Testing of heavy metals (Cu, Pb, Zn, Cd, and Cr) performed on 28 samples of sea water and 28 subsurface sediment samples using the method of Atomic Absorption Spectrophotometry (AAS). The purpose of this study was to obtain data and information on current environmental conditions of heavy metal content in seawater and subsurface sediment. Heavy metal content (sea water in mg/l: subsurface sediment in ppm) measured as follows: Cu ( <0.005 : 15.000-169.500 ); Pb (0.005-0.011 : 14.000-58.100); Zn (0.005-0.007 : 95.800-333.000); Cd (0.006-0.015 : 0.012-0.750); Cr (<0.001 : 45.320-139.180). Based on the Storet method shows the value of water quality status of sea waters is -12, which means that the seawater quality in these waters belong to a class C (medium contaminated). While the status of sediment quality in these waters indicate subsurface sediment quality score status value is 0, which means that subsurface sediment quality belongs to the class A (not polluted/correspond to the quality standards). It is clearly seen that the threshold value (NAV) of heavy metals in sediments is much higher than the NAV of heavy metals in water.

GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROPHOTOMETRY AS A METHOD FOR ANALYZING HEAVY METAL. Heavy metal, mostly present in a (ultra) trace-level, becomes one of the hazardous pollutants due to its toxicity, bioaccumulative, biomagnification characters. Conducting a micro analysis of these trace-level pollutants, a sensitive instrument and method are strongly recommended. Graphite Furnace Atomic Absorption Spectrophotometer (GFAAS) offers a solution for the challenge. It uses the principle of light emission absorption by nascent atom cloud from the metals. The analysis has been developed in three stages of the tube heating programs, i.e. drying, ashing and then atomizing element at 3000° C. Since the injected sample is almost completely atomized, the sensitivity of GFAAS is extremely high and this value is covering up the disadvantages of the other analyses. Therefore, the GFAAS analysis is suitable fo ultra-trace analysis of ultra-trace pollutants like heavy metals in environment.
