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.
