【 摘 要 】

The objective of the study was to examine the levels of mercury concentrations in plants due to the traditional gold mining of Buladu, Sumalata District, Gorontalo Regency. Buladu gold mining was located in Sumalata District, North Gorontalo Regency, Gorontalo Province. Plant samples were taken in 3 locations, namely plants living along the Hulawa River, living near to the tailings and those in residential areas. The number of plants that became the samples along the Hulawa River were 13 samples, 5 samples in the tailings, and 16 samples in residential areas. The total number of plants were as many as 34 samples. The samplings were taken from the roots and leaves so that there were a total of 68 samples. Plant analysis was carried out using mercury analyzer at UGM Integrated Research and Testing Laboratory. The quality standard used as a reference for plants employed the Decree of the Director General of National Agency of Drug and Food Control No: 03725 / B / SK / VII / 89, where mercury levels could not exceed 0.5 mg / kg. Data analysis used tables and graphs and was subsequently interpreted. The results showed that the concentration of mercury in the leaves of plants living along the Hulawa River ranged from 0.00142 mg / kg to 0.41617 mg / l and that in the root ranged from
