Abstract
Tailing from artisanal gold (Au) processing activities using amalgamation in Kalirejo Village, Kulon Progo Regency, Yogyakarta, is recognized as a major issue on the environment. The mercury (Hg), media used as a Separator of gold and other minerals, most likely contaminates the plampang River and the surrounding ecosystems. Thus, this study aimed (i) to examine the concentration of mercury on abiotic and biotic components and (ii) to determine the contamination level. Stream water, sediment, and benthic macro-invertebrates samples were purposively collected based on the scattered location of mining activities around the river. The mercury content was then measured using a mercury analyzer. The results showed that the maximum mercury concentration in stream water, sediments, and benthic macro-invertebrates were 0.002, 0.135, and 0.106 mg/L, respectively. In conclusion, the status of water quality in the Plampang River still meets the standard of good quality (PI 0.73). The level of pollution in the sediments shows no contamination until sufficiently polluted ( Igeo 0-1). The degree of pollution on the biotic component ( benthic macroinvertebrates) categorized into low accumulation properties (BCF < 100). Furthermore, the community perception of Kalirejo Village due to the gold mining activities on Plampang River and environmental management strategies were also discussed.
