“…In the Pancurendang Village gold mining area, the biological accumulation coefficient (BAC) of mercury in herbaceous plants ranges from 0.11 to 4.54, potentially indicating a medium to high category of mercury accumulator. According to this study, Plectranthus sp., which grows in regions with gold mining, has the greatest capacity to accumulate mercury, with a BAC value of 4.54 [17]. The BAC value was obtained on Plectranthus sp.…”

Sludge (tailing), a waste product of the amalgamation process used in the mining of gold, contains a high concentration of the heavy metal mercury (Hg). It is well known that mercury builds up in large quantities in Plectranthus sp. herbaceous plants in the Pancurendang Village Small-Scale Gold Mining area. The study intends to: 1) quantify the amounts of mercury present in plant organs and media tailing during phytoremediation treatment; 2) examine the mechanisms and capacities of plant phytoremediation using values of the Biological Accumulation Coefficient (BAC), Biological Concentration Factor (BCF), and Translocation Factor (TF); and 3) determine the impact of percentage variations in tailing and time on Plectranthus sp.’s capacity to accumulate mercury. On a lab scale, phytoremediation of tailings is done with concentrations of 0%, 30%, 50%, and 100%. Planting medium is combined with dried tailings. Pots are used for phytoremediation, and the residence times are 10, 20, and 30 days. With the use of a mercury analyzer, the amount of mercury present in plant media, roots, and shoots is determined. Using the BAC, BCF, and TF values, the mathematical calculation of phytoremediation ability is performed. Hg content ranged from 1.82 to 16.23 ppm in shoots and 5.15 to 37.19 ppm in roots. Throughout the course of treatment, the tailings Hg concentration varied between 13.18 and 220.05 ppm. Plectranthus sp. is categorized as a medium accumulator with a phytoextraction mechanism, according to the analysis’s findings. Hg phytomining is possible with Plectranthus sp., the TF value is 2.38. Within 10 days, Plectranthus sp. most effectively accumulates 50% Hg in tailings.

“…A large fraction of the research on phytoremediation of mercury has focused on finding mercury accumulator or hyperaccumulator plants because, despite their phytotoxic characteristics, there are plant communities that grow on mercury-contaminated sites [20][21][22][23][24]. Hyperaccumulator plants can accumulate large numbers of heavy metals at concentrations 10 to 100 times higher than nonhyperaccumulator plants can tolerate [25].…”

Mercury is classified as one of the world’s most toxic and dangerous pollutants. It tends to bio-accumulate and biomagnify within the trophic chain and is persistent. Various approaches are available to remediate Hg-affected sites, including phytoremediation, which includes the use of plants to clean up contaminated environments. Phytoremediation of mercury contamination is at-tracting increasing attention because of its advantages: it is environmentally friendly, inexpensive, simple, and can improve soil fertility. In this report, VOSviewer, and Bibliometrix software were used to analyze 457 and 697 documents published from 2000 to 2023, retrieved from the data-bases WoS and Scopus, respectively. China, India, the United States, and Spain are the top four most productive countries. The largest topic area was environmental sciences, and the Chinese Academy of Sciences was the organization that contributed the most to the overall number of pub-lications. The keywords with the highest frequency, excluding phytoremediation and mercury in WoS, were heavy metals, accumulation, cadmium, soils, and phytoextraction. In Scopus, the most frequent keywords were bioremediation, heavy metals, soil pollution, bioaccumulation, biodeg-radation, and environmental. From the above analysis, we concluded that future research should focus on 1) finding native plants, 2) increasing remediation ability through assisted phytoremedi-ation, 3) studies of molecular mechanisms in plants with phytoremediation potential, and 4) ge-netic engineering applications. This study provides insight into trending themes and serves as a reference for future research.

Heavy metal waste can be caused by anthropogenic activity. This waste can pollute soil and water far from the source. One of the ways to immobilize the heavy metals is using a plant that can accumulate them. This research aimed to screen potential plants that can be used as remediation agents due to ASGM activity in the post-mining area. This study was conducted at PT Napal Umbar Picung (NUP), Tanggamus Regency, Lampung. The study collected the potential hyperaccumulator plant from contaminated areas. Plant samples were dried at 80°C for three days in a ventilated oven. The dried samples were powdered using the Philips Blender 5000 series into fine-grained sizes. The powder samples were analyzed using X-ray fluorescence (XRF). The highest concentrations of As, Cd, Fe, Hg, Ni, Pb, and Zn in the shoot tissues of ASGM at PT NUP were 285.8 mg/kg, 11.7 mg/kg, 258,320 mg/kg, 501.6 mg/kg, 57.4 mg/kg, 806.2 mg/kg, and 4,520 mg/kg. The results showed that the hyperaccumulator plant of Hg was Alpinia galanga. Christella sp. Chromolaena odorata, Clidemia hirta, Melastoma malabathricum, and Nephrolepis cordifolia. This study can conclude that the plants can be used as a phytoremediation approach to heavy metals contamination such as As, Cd, Fe, Ni, Pb, Zn, and especially Hg.
