Abstract
Abstract. Gold mining activities in the Lake Sarantangan area including the Sungai Raya watershed lasted for a long time
during the 18th century by Chinese workers from China, gold extraction activities using mercury and without any waste
processing, thus increasing the level of sediment toxicity of Lake Sarantangan. This study aims to identify the level of
sediment quality of Lake Sarantangan. 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
ISQV-low (0.28), Slightly Elevated Stream Sediments (SESS) (0.07), the concentration of heavy metals in the sediments of
Lake Sarantangan has exceeded the quality standard of 13 quality standardscausing the level of toxicity of Lake Sarantangan
sediment to be higher.
