“…About 15 cm 2 of each sample was crushed to a fine powder with a powder mill (Varian PM-2005m, Osaka Chemical Co., Ltd., Osaka, Japan) to produce homogeneous samples for analysis. The tree bark powders (30 mg of each sample) were digested with a mixture of indium (In) and HNO 3 in a ratio of 3:100, before the heavy metal concentrations such as Pb, Zn, Fe (especially Hg), and As were determined with PIXE [19,20] at Iwate Medical University (Iwate, Japan). The dimensions of the tree bark samples (about 15 cm 2 ) were calculated with the ImageJ (version 1.48) software (National Institutes of Health, Bethesda, MD, USA).…”

Abstract:We report the atmospheric Hg contamination in an artisanal and small-scale gold mining (ASGM) area in North Gorontalo, Indonesia. It is well known that atmospheric Hg contaminates the air, water, soil, and living organisms, including trees. In this study, we calculated total weight of heavy metals, especially Hg, and quantitatively measure the concentrations of heavy metals, especially Hg, in tree bark from an ASGM area. Tree bark can be used for the environmental assessment of atmospheric contamination because it attaches and absorbs heavy metals. Atmospheric Hg and other heavy metals, including Fe and Mn, and As were detected on the tree bark samples. The total weight of Hg, As, Fe, and Mn in the tree bark samples ranged from undetectable (ND) to 9.77, ND to 81.3, 124-4028, 37.0-1376 µg dry weight (DW), respectively per weight of sample. Based on quantitatively analysis micro-PIXE, the highest concentrations of all these metals were detected in the outer part of the bark. We conclude that tree bark can adsorb atmospheric contamination, which is then absorbed into the inner tissues.

It is well known that atmospheric mercury (Hg) contaminates air, water, soil, and living organisms, including trees. Therefore, tree bark can be used for the environmental assessment of atmospheric contamination because it absorbs heavy metals. This study aimed to establish a new biomonitoring for the assessment of atmospheric Hg pollution. Reporting on atmospheric Hg contamination in an artisanal and small-scale gold mining (ASGM) area in North Gorontalo, Indonesia, we calculated the total weight of Hg (THg) and quantitatively measured the concentrations of Hg in the tree bark of Mangifera indica,Syzygium aromaticum, Terminalia catappa, and Lansium domesticum. The THg of Hg in the M. indica tree bark samples ranged from not detected (ND) to 74.6 μg dry weight (DW) per sample. The total Hg in the tree bark of S. aromaticum, T. catappa, and L. domesticum ranged from ND to 156.8, ND to 180, and ND to 63.4 μg DW, respectively. We concluded that topography significantly influences the accumulation of Hg together with local weather conditions. A mapped distribution of the THg suggested that the distribution of THg in the tree bark was not affected by the distance to the amalgamation site. Therefore, tree bark can be used as biomonitoring of atmospheric Hg contamination for the assessment of ASGM areas.

“…The TF is calculated from the heavy metal concentrations and is used to evaluate the phytoextraction ability of the plant, in particular the plant's ability to translocate heavy metals from the roots to the shoots. The TF is defined as the ratio of the heavy metal concentration in the shoots to that in the roots as follows [11].…”

Artisanal and Small Scale-Gold Mining (ASGM) is one of the anthropogenic activity of heavy metal contaminations sources and indicated high negative impact on the environment, especially the mercury (Hg) contaminations. The aim of this research was screened potential plants that can be used as remediation agents due to ASGM activity in the post-mining area. This study was conducted in Katingan Regency, Central Kalimantan and at PT Napal Umbar Picung (NUP), Tanggamus Regency, Lampung. The study collected the potential hyperaccumulator plant from contaminated areas. Plant samples were dried at 80ºC for 3 days in a ventilated oven. The powder samples were weighed and dissolved with 6 ml of HNO3. Then, samples were digested using a Multiwave 7,000. Dissolved samples were analyzed using X-Ray Fluorescence (XRF).The highest concentrations of As, Fe, Hg, Pb, and Zn in the shoots of ASGM in Katingan Regency were 90 mg/kg, 9,837 mg/kg, 1,023 mg/kg, 114 mg/kg, and 315 mg/kg, respectively. The analysis results of highest concentrations of As, Fe, Hg, Pb, and Zn in the shoots of PT NUP were 97.2 mg/kg, 15,4710 mg/kg, 162.9 mg/kg, 152.4, and 1,220 mg/kg, respectively. The results showed that the hyperaccumulators plant of Hg were Christella sp., Hoya sp., Stenochlaena sp., Athyrium sp., Palhinhaea sp., and Pecluma sp in both ASGM area, Katingan and PT NUP. This study can be concluded that the plants can be used as phytoremediation approach of heavy metals contamination such as As, Fe, Pb, Zn, and especially Hg.
