“…The average natural level of Zn in the Earth's crust is 70 mg/kg (dry weight). Fe is the primary mineral compound that is the dominant element in weathered rocks (Fashola et al, 2016;Nurcholis et al, 2017). Cr is widely distributed in soils and rocks where it occurs in minerals such as chromite, and its concentration ranges below 60 mg/kg in natural soil.…”

The objectives of the present study were to determine the concentrations of heavy metals and metalloids in frogs (Sylvirana nigrovittata) and to assess chromosome aberrations (CAs) in frogs collected from the Nam Kok River near the Sepon gold-copper mine, Lao PDR, as compared with those from a reference site. The results showed that the concentrations of As, Cd, Cr, and Mn in the frog muscle samples exceeded the standard values, and the accumulation of heavy metals in the frogs from the two sampling sites was significantly different (P <0.05), particularly Ba, Cd, Cr, Cu, Fe, Mn and Ni. Chromosome assessment of S. nigrovittata from the study site revealed 13 types of CAs, and the highest total number of CAs was isochromatid gap with a percentage of 31.80%. Furthermore, the total number of CAs, cell number with CAs and percentage of CAs in the frogs from both sites were significantly different (P <0.05). The results of this study suggest that heavy metal and metalloid from the Sepon gold-copper mine area negatively affected S. nigrovittata in terms of chromosomal defects.

“…In particular, herpetofauna has been extensively used as bioindicators of habitat damage since they play an important role in ecosystems as part of the food chain (Fabian et al 2013) Selogiri Sub-district, Wonogiri District, Central Java Province, Indonesia, is an area with a high potential for gold deposits. As a consequence, some villages in this subdistrict attract many people to extract the gold resource contained in the village (Nurcholis et al 2017). The artisanal mining activities have an impact on the ecosystem environment in the Selogiri Sub-district, including flora and fauna.…”

Abstract. Isworo S, Oetari PS. 2022. Flora and fauna in the areas around artisanal gold mining in Selogiri Sub-district, Wonogiri, Indonesia. Biodiversitas 23: 6600-6618. Artisanal or small-scale gold mining has devastating impacts on the environment due to negligence of the principles of good environmental management. In particular, the mining activities often involve vegetation clearing and topsoil removal, which affect the biotic elements of the mined landscape. Selogiri Sub-district, Wonogiri District, Central Java Province, has a gold mineral resource that drives many traditional mining activities that have an indirect impact on the ecosystem's species diversity and community structure. This research aimed to investigate the diversity of flora and fauna in Selogiri Sub-district by comparing the area where the artisanal gold mining occurred (the inside area) and the areas surrounding the mining (the outside area). Six groups of taxa were observed in this study, including the plant group using the plot method, avifauna (birds) using Indices Ponctuels d'Abondance method, Odonata (dragonflies) and Lepidoptera (butterflies) both using visual encountering survey (VES) method, micromammals (Rodentia) using traps, VES, and camera traps and herpetofauna (amphibians and reptiles) using VES method. The diversity values of each taxa group in the inside and outside area were calculated and Sorensen's Coefficient Similarity Index formula was analyzed to see the community similarity between the two areas. A total of 243 species were found, consisting of Lepidoptera (35%), flora taxa (29%), avifauna (16%), herpetofauna (9%), Odonata (7%), and mammals (3%). The avifauna and Odonata had higher diversity values in the outside area than in the inside area. Similarly, the outside area had a higher diversity value for mammalian taxa documented using the VES method. Meanwhile, using the trap method, the taxa of Lepidoptera, herpetofauna, and mammals had higher diversity value in the inside area than in the outside. Nonetheless, the two areas had moderate similarity in the composition of flora and fauna species, with a community similarity value of less than 60% for all taxa studied. Conservation activities and off-site tree planting are solutions for restoring ecosystem structure and function to support ecological stability and biodiversity.

“…The existence of heavy-trace metals, especially lead, due to mining activities in the environment, has caused a great deal of concern owing to its toxicity to human life (Moors and Dijkema, 2006, Montanaro et al, 2001, Nurcholis et al, 2017. Leaching of the poisonous metals unavoidably will pose a hazard to the environment and public health worldwide (Ye et al, 2015).…”

In this paper, the results obtained from various leaching tests to determine the leaching behavior of lead from lead-zinc mine tailing under natural conditions were evaluated. In order to measure the level of toxicity of the tailings, synthetic precipitation leaching procedure (SPLP), toxicity characteristic leaching procedure (TCLP), leachate extraction procedure (LEP), and field leach test (FLT) protocols were used. The effect of liquid to solid ratio, particle size, contact time, and pH on lead release from tailings was also tested. Based on the results, the release of lead from the tailings was entirely affected by pH and amphoteric leaching behavior was observed. According to the results of the TCLP leaching protocol, the tailings categorized as hazardous material. Lead mobility index for S1 and S2 samples were 51% and 5.6%, respectively. The release of lead from the tailings was affected by the solubility process. The highest amount of lead release from S1 and S2 samples were observed in the particle size range of 0.3-0.5 mm and 0.6-1.0, mm respectively. According to the results, management of tailings and prevention of the release of lead into the environment, requires a special strategy. Controlling the amount of pore water, the size range of tailing particles in order to prevent wind erosion, prevent in situ pH changes, and acidification of tailings, and classification is essential factors in tailing management. In fact, health and diet security, climate change, safe water, accountable production, biodiversity, and ultimately the people must be considered in the planning of the authorities.
