Abstract

Illegal gold mining activities have caused significant environmental contamination, especially by heavy metals such as aurum (Au). Herbaceous plants were chosen as the object of study because of their ability to absorb and accumulate heavy metals from the soil. Metal uptake in plants can provide an indication of the level of pollution and phytoremediation potential. This study aimed to evaluate the bioaccumulation of Au in herbaceous plants at an ex-illegal gold mining site in Pancurendang, Banyumas, Indonesia. The research method involved collecting 6 soil samples and 19 herbaceous plant samples from several locations. Analysis of aurum was conducted using the Inductively Coupled Plasma Mass Spectometry (ICP-MS) method. From the analysis, it was found that the concentration of aurum in the herbaceous plants was higher than the concentration of aurum in the soil. This shows the potential of using herbaceous plants as Au phytoremediation and phytomining.
