The hydrosphere of catchments, which are disturbed by mining, is formed under the influence of not only natural, but also, to a large extent, man-made factors over a long period, sometimes tens or even hundreds of years. After the cessation of production, the return of the mining territory to a state as close to natural as possible is possible, as world experience shows, in exceptional cases, provided that the process of reclamation and revitalization is planned at the design stage of mining. In old industrial areas, the selfhealing processes of the hydrosphere are of great importance, which determine the time during which the territory should be considered as an object of accumulated environmental damage. At present, the total removal of metal compounds by mine waters in the discharge zones at flooded copper-ore mines of the Sverdlovsk region amounts to hundreds (manganese, zinc) and even thousands of tons per year (iron). The duration of self-rehabilitation of the hydrosphere of mining areas at the post-operational stage, i.e. the duration of the period during which the content of the main polluting components (copper, zinc, iron, sulfate ion) is reduced to the maximum permissible or background values, is tens or even hundreds of years. During this time, in order to prevent pollution of the underground and surface hydrosphere, expensive measures are required to implement a system of purification of underground and surface waters of the old industrial territory. The research was carried out on the basis of observations of the chemical composition of water bodies in the territory of the abandoned Levikhinsky mine since the beginning of the 2000s.

This article presents the study results of the change dynamics in the chemical composition of water in Lake Iskanderkul and the rivers flowing into it, as well as the comparison of water quality in the water bodies of the Iskanderkul Basin and several mid-stream tributaries of the Zarafshan River. It was established that the chemical composition of water in Lake Iskanderkul and its tributaries meets the requirements of the corresponding state standard (GOST 2874-82 “Drinking Water”). However, in terms of dissolved oxygen, copper, zinc, lead and iron the water in Lake Iskanderkul does not satisfy fish farming requirements. The main water pollution sources in the area include such natural phenomena as floods, avalanches, mudslides, and rock dissolution.

Abstract   Exploitation of natural resources through unlicensed gold mining (PETI) is not in accordance with mining operational standards occurring along the Noeltoko River, West Miomaffo Subdistrict, Timor Tengah Utara Regency, East Nusa Tenggara Province resulting in damage and environmental degradation. Changes and environmental damage include the formation of dug holes around the river flow, turbidity of water, changes in river flow. Other problems that arise are conflicts between these PETI workers and with other communities. This community service activity aims to provide an understanding to the community about the importance of maintaining and caring for rivers from excavation in the river walls that can cause debris / landslides explaining the impact of the use of hazardous materials such as mercury / mercury and cyanide, socialization of regulations regarding the formation of People's Mining Areas (WPR) ), introducing "sluice box" equipment to help the process of separating gold sand from sand. This activity was supported by the UPT ESDM Atambua Branch and was followed by 40 people who used to mine on the Noeltoko river. It is expected that the guidance and assistance can raise public awareness to be able to mine but still preserve the environment   Keyword: PETI, Noeltoko, WPR, sluicebox,   Abstrak   Eksploitasi sumber daya alam melalui Penambangan Emas Tanpa Izin (PETI) tidak sesuai dengan standar operasional penambangan terjadi di sepanjang sungai Noeltoko-Kecamatan Miomaffo Barat, Kabupaten Timor Tengah Utara Propinsi Nusa Tenggara Timur yang mengakibatkan kerusakan dan penurunan kualitas lingkungan.

Operating life of a mine lasts from a few years to several decades. Mine closure occurs once the mineral resource is exhausted, or operations are no longer profitable. Mine closure plans are required by most regulatory agencies worldwide before a mining closure permission is granted, and must demonstrate that the site will not pose a threat to the environment and health of the society in future. The article describes a new tool, the brownfields methodology, which can help to promote the revitalization of old mining areas as a part of their technological modernization and subsoil full extraction with environmental damage reduction.

The effects of supplementing a wheat/animal protein diet with copper (nil, 125 or 250 ppm), zinc (nil or 150 ppm) and iron (nil or 150 ppm) were studied in a 2 x 2 x 2 x 3 factorial experiment with 48 pigs. The diet was restrictively and individually fed to barrows and gilts between 18 and 73 kg liveweight. Daily rate of gain, feed conversion ratio and carcase score were not affected by the supplementary minerals. Supplementary copper increased the storage of manganese, zinc and copper in the liver. Although liver copper levels were greater in both sexes at 250 than at 125 ppm copper, barrows stored more copper than gilts at the higher level. Adding 150 ppm zinc at the same time as 250 ppm copper reduced liver copper storage in the barrows to the level of that in gilts given the same amount of copper. The iodine number, i.e, softness, of backfat in barrows was increased to that of gilts by 250 ppm copper; gilts were unaffected. Zinc supplementation also increased backfat softness in barrows but not in gilts. Despite this, 150 ppm zinc partially reduced the effect of 250 ppm copper on backfat in barrows.

Ecological Problems

Environmental damage, climate change, and increasingly intense natural disasters are serious problems faced by humanity in this millennium. More ecological damage occurs due to expensive and destructive human activities. Illegal logging, expansion of mining areas, pollution of water sources, overfishing, trade-in protected wildlife continue to happen, and the scale is even greater. Meanwhile, climate change is increasingly visible and impacting communities in urban to rural areas. Coastal cities in the United States to coastal villages in the north of Java and the microstates of the South Pacific facing the real impact of sea-level rise. Disasters that occur bring not only material losses but also socio-economic consequences for people affected. The emergence of new ecological problems is being faced by humanity. The complexity of ecological problems is nonlinear, turbulent, and dynamic. This was the theme of the panel (New) Ecological Problems: Defining the Relationship between Humans and the Environment at the Symposium on Social Science 2020. This paper, part of the SOSS 2020 panel on ecological problems, argues for countries to overhaul and “reset” their public health and economic systems to ones based on strengthening multilateral institutions and collaboration, and to abandon or seriously curtail neoliberalism models that have failed. It also argues that the profession of journalism also needs to approach climate change strategies with as much urgency as for addressing the global COVID-19 coronavirus pandemic. The current crisis is a precursor to further crises unless the globe changes its ways to heal both people and the planet.

The Relationship

Socio-environmental conflicts are situations that exemplify human rights transgressions caused by extractive activities. These are present in developing countries where extractivism, imperialism, and colonialism paradigms prevail. In the context of Mexico, criminalization, violence, and the absence of rule of law promote these conflicts, frequently aggravated by involvement with private interests. In the last 20 years, the relationship between human rights in the mining sector and its impact on the environment has been a critical research subject. This paper aims to carry out a systematic review to analyze human rights transgressions related to the mining industry’s impact in Mexico, and identify factors causing socio-environmental conflicts. The current study shows a systematic analysis based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology. This method contributed to the collection of references that describe conflicts due to human rights transgressions and environmental damage in mining areas in Mexico. Human rights transgressions caused by mining in a Mexican context demonstrate the inability of the state to stop the increase in socio-environmental conflicts and its lack of concern towards preventing damage to the environment.

Abstract Small-scale mining has a very long history, and the majority operated without permits: coal and almost all kinds of minerals they cultivate. The area of operation covers most of Indonesia. There are grab licensed mining areas. The number of illegal miners is estimated at more than 3.6 million people, about 1.4 million gold miners. This activity has been going on for years, never be solved. The Negative impacts of illegal mining, include the loss of potential state revenue, environmental damage and mercury pollution, mining accidents, social vulnerabilities, conflicts with licensed companies, and no resource conservation. It is time for this issue serious attention of the government to be resolved. Legalization by granting permits can be a business guarantee that will grow responsibility for regulations and become the basis for environmental management. This research is socio-legal research. The role of local governments, associations, and the state-owned company is required in technical guidance on mining and the environment, institutions, business management, and product markets. If the activities can be managed and developed, the negative impacts can be overcome. So, the benefits of their business can become a forum for people’s activities in the mining sector, and state revenues can be collected.

Sand mining activities in Pasir Sakti District, East Lampung Regency, have changed the landscape and the allotment of land around it. The former sand mining area now becomes large puddles that are not utilized. This study aimed to analyze the suitability of water quality in ex-sand mining areas for tilapia (Oreochromis niloticus) culture. Observations were carried out at three stations in January-October 2019. Water quality measurements were performed to check water depth, clarity, temperature, current, dissolved oxygen, pH, salinity, nitrate, phosphate, iron, sulfate, and phytoplankton density. Analysis of suitability for aquaculture was carried out using weighting and scoring methods. Based on the results of the suitability analysis, the scoring result of the sand mining land for O.niloticus culture was in the range of 64% -68%. This score is classified as marginally suitable. The parameters with low scores are clarity, dissolved oxygen, temperature, pH, ammonia, phosphate, and iron (Fe) concentration parameters. Meanwhile, salinity, nitrate, sulfate, and phytoplankton density indicate conditions that are suitable for aquaculture. Therefore, severe treatment is needed to improve water quality to make it ideal for O.niloticus culture.

Abstract The mining of underground deposits causes the inflow of water to workings and the necessity of pumping them to the surface. The mining plant of KGHM Polska Miedź S.A. extracts copper ore in plant branches with different hydrogeological conditions. The inflowing water into the workings is characterised by variable mineralisation, which depends on the location of the branch. In the south-western part of the deposit, a low-mineralised stream with a relatively high flow rate can be observed, while the outflow of highly saline waters occurs in the north-eastern branch. Despite the activities undertaken that aim at using the pumped-off mine waters industrially, it is necessary to deposit them into the Odra River. Reducing the environmental impact on the Odra River is one of KGHM's goals, which is being implemented by stabilising its salt concentration at a safe level. The paper presents the results of a 3D simulation of brine plume propagation based on a numerical model of advection–diffusion and turbulent flow. Bathymetric data from a section of the river approximately 500 m long and point data from an Odra water quality test were used to develop and validate the model. The paper discusses the types of factors that minimise the impact of brine discharge. The developed model will be used in the future to propose solutions that accelerate the mixing of mine waters with the waters of the Odra River.
