Abstract
Gold mining activities in the Sarantangan Lake area including the Sungai Raya watershed lasted for a long time during the 18th century, gold extraction activities using mercury and without any waste processing, thus increasing the level of sediment toxicity of Sarantangan Lake. This study aims to identify the level of sediment quality of Sarantangan Lake. Measurement of mercury concentration in sediments using the H-VG method was carried out at the Pontianak Industrial Research and Standardization Center Laboratory (BARISTAND). The measurement results show that the mercury concentration of 15 sediment samples shows a concentration value of 0.510 mg / kg - 1.30 mg / kg, from TEL (0.17 ppm), ERL, NOAA-ERL, ANZECC-ERL, ANZECC-ISQG Low, HONGKONG -ISQG Low (0.15 ppm), LEL, MET (0.2 ppm), CBTEC (0.18 ppm), EC-TEL (0.13 ppm), SQO Netherlands Target (0.3 ppm), Hong Kong ISQVlow (0.28), Slightly Elevated Stream Sediments (SESS) (0.07), the concentration of heavy metals in the sediments of Sarantangan Lake has exceeded the quality standard of 13 quality standardscausing the level of toxicity of Sarantangan Lake sediment to be higher.
