内容記述タイプ Abstract
内容記述 As a part of the monitoring program on mercury contamination in Talawaan Watershed, north Sulawesi Indonesia, total mercury contents in plankton along the watershed has been determined. The plankton samples were collected three times with two-week interval from 12 sampling sites along the three main rivers (Talawaan River, Kima River and Bailang River). All values ranged from 0.4 to as high as 118μg mercury per g dry weight of concentrated plankton, not implying content in individuals of plankton. In general, plankton collected from sites around tailing ponds along the three rivers observed contained more Hg than do plankton collected upstream. In upstream area, T1 and B1 (in average of 4.03 and 6.5μg/g d. w, respectively). Total mercury in plankton collected from downstream of Talawaan River were much higher, 3-13 times than those in upstream (in average of 4.03μg/g d. w), where the highest levels in sites the sites T2 and T3 where the wastes of most active processing units drained into. Mercury concentrations in sampling sites along Bailang River and Kima River were lower than those in Talawaan River, i. e. in range of 9.2 to 25.5μg/g d. w. and 3.1 to 10μg/g d. w., respectively. This fact is a clear evidence for mercury emission from the existing gold processing plants. Gold mining activities in the study area are considered exclusive factor for environmental contamination by mercury, and high levels in plankton suggest that a process of bioaccumulation is occurring, which needs more clarification in the future.
