  • 摘要:This paper reports copper, zinc, lead, cadmium, and chromium records of Jakarta Bay sediment since 500 AD of a 150 cm long gravity core (TJ–17, 106.902488°E, 5.99381°S). The core was acquired from the eastern part of Jakarta Bay in 2010 onboard RV Geomarin I by the Marine Geological Institute–MEMR. We applied core scanning, grain size and elemental analyses to track environmental changes. Core scanning was conducted by multi sensor core logger, grain size analysis was carried out by sieving and pipette methods and heavy metal concentration was analyzed using atomic absorption spectrometry on bulk samples. The results yield baseline values of Cu at 12.88 ppm, Zn at 95.5 ppm, and at Cr 60.13 ppm. Vertical record of heavy metals show three stages of environmental changes in the region: (I) 476–933 AD, (II) 933 – 1799 AD, and (III) 1799 – 1991 AD. These changes are interpeted as related to land use changes caused by human activity in the West Java region since Tarumanagara to modern Indonesia.
