High Escherichia coli number (116–149/mL) was detected downstream in the Ciliwung River. In addition to evaluate mercury pollution caused by gold mining, mercury contents of water and sediment samples from the Cikaniki River, and from paddy samples were determined. The water was not badly polluted. However, toxic metals such as mercury were detected at levels close to the baseline environmental standard of Indonesia (0.83–1.07 μg/g of sediments in the Cikaniki River). From analyses of the paddy samples (0.08 μg/g), it is considered that there is a health risk caused by mercury.Springer New YorkJournal Articleapplication/pdfhttp://hdl.handle.net/2115/47657https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/47657/1/YsudaBECTHUSCAP.pdf0007-48611432-0800AA00104307Bulletin of Environmental Contamination and Toxicology8766696732011-12enginfo:pmid/21979139info:doi/10.1007/s00128-011-0411-zThe final publication is available at www.springerlink.comauthor
