Anthropogenic activities, such as domestic and industrial activities, around rivers could affect the quality of the rivers and surrounding areas. These activities could produce heavy metals and magnetic minerals as anthropogenic materials. The presence of anthropogenic materials changes river condition, including magnetic properties of river sediments. We have examined magnetic susceptibility of Cimande River sediments that can be used as tracer of environmental contamination. The research is integrated with Electrical Conductivity (EC) and Total Dissolve Solid (TDS) analysis of river water as well as river sediments. The results show that water river has EC and TDS values below international criteria for water quality. However, EC and TDS measurements of river sediments, by applying similar international criteria, show that number of samples have EC and TDS values close to threshold values and some samples are in higher level. Magnetic susceptibility measurements infer that river sediments have |LF in range of 507.0 – 1430.9 (× 10-8) m3kg-1. It suggests that the samples are dominated by ferrimagnetic minerals. According to |FD (%), in majority samples have |FD (%) below <4% indicating the anthropogenic origin of magnetic minerals. [ABSTRACT FROM AUTHOR] |
