Opis:: Artisanal small-scale gold mining presents numerous opportunities for Uganda's rural poor. However, it also poses serious environmental, health and safety challenges. A suite of data collection methods including interviews, focus groups discussions, water and soils sampling were used to examine the perceptions of miners on the status, prevalence and extent of mercury use in artisanal gold mining, mercury transit routes and toxicity levels of soils and water in Karamoja sub-region. It also explores the health, safety and environmental implications of artisanal small-scale gold mining in the sub-region. The findings show that trade and access to mercury is widespread; although trade in, access to and its use is highly secretive. Traders access mercury through a number of ways including smuggling across the porous borderline and formal, but covert, importation. Miners then discreetly access it through undercover sales in jewellery shops and in affluent gated communities in Uganda's capital, Kampala. Soil and water samples showed mercury levels that exceeded the minimum acceptable limits of 0.03 mg/kg and 0.006 mg/l respectively. Further, artisanal small-scale gold mining is associated with massive land clearances and landscape deformations. It has invariably scarred the countryside with piles of waste and uncovered pits that are a source of accidents and ideal breeding grounds for vectors.

Opis:: This article presents the results of comparing mercury content measurements made with the AMA254 automatic atomic absorption spectrometer with measurements obtained using the CVAAS method in a different laboratory. The aim of the article is to show the potential of applying the AMA254 analyzer to measure low mercury content (including trace amounts) without the pre-treatment (mineralization) of the samples. Mercury, as one of the more toxic elements (according to Agency for Toxic Substances and Disease Registry), which is present in hard coal, is the main cause of the problems resulting from the environmental pollution associated with hard coal combustion, as well as storing coal processing waste, such as extractive waste and combustion by-products including slag, ash, and slag-ash mixtures (CBP). Precise measurements of trace mercury content in extractive waste and combustion wastes (CBP) is very important in the context of the act on waste (2008 and 2013), BAT regulations 2016 and new BAT regulations (coming into force by 2021), which introduce more and more rigorous limits on mercury emission into the environment. The AMA254 analyzer performs analysis in a short period of time (approximately 5 min), enables repeatability, is intuitive to use and has very high accuracy and precision (the lower limit of quantification is 0.00001 μg Hg), is an ideal tool for measuring low mercury content in samples of both fuels and coal processing waste.

Opis:: This paper presents the results of a study on the influence of the temperature of characteristic zones of coal combustion in a stoker fired boiler (drying, degassing, and burn-out), on changes in physical and chemical parameters of bituminous coal and slags. This information is important as it helps identify the impact of coal properties on the accumulation of trace elements, primarily mercury, in combustion waste. The study is the continuation of research work on the impact of mercury compounds accumulated in combustion waste on the natural environment (mercury from landfills of slag, and fly ash). Studies were undertaken because no in-depth analysis of the impact of the temperature of particular zones of stoker fired boilers on the physical and chemical parameters of the post-process slag, including mercury content, had been reported in literature. Both of the coals examined, classified as bituminous coal according to the International Classification of Seam Coals and of type 32.1 according to the PN-G97002:1982 standard, showed an average mercury content of 0.0849 mg/g. In the chemical composition determined for the ash derived from burnt coal, the dominance of SiO2 and Al2O3 over other oxides was found. This feature results in the increase of the softening temperature and ash melting and, therefore, during the combustion of coal tested in a stoker fired boiler, only ash was subjected to the sintering process. Mercury content in the other examined samples taken from various locations of the stoker fired boiler (drying – 32-1050 ºC, degassing – 1050-1020 ºC, and burn-out – 1020-400 ºC) varied from 0.0668 to 0.0009 mg/g and was determined with the use of a LECO atomic absorption spectrometer. The analyses of the elemental composition, performed with the application of XRF spectrometry, for ash obtained from samples collected from different sampling points of the stoker fired boiler showed that the largest concentration of trace elements was observed for the ash derived from the samples collected in the degassing zone (temperature range 1050-850 ºC).

Opis:: Coal consumption secures more than 50% of needs of Polish economy for primary energy carriers and the consumption of hard coal alone amounts 70-80 million Mg annually. Almost 14% of hard coal consumption - up to 11 million Mg per year - fall to households in Poland. Coal combustion in domestic furnaces and boilers is regarded as the main source of emissions into the atmosphere, referred to as the low-stack emission. The matter of the paper is the assessment of the emission of mercury from the households sector as the result of coal combustion. The results of the assessment were collated with GUS data on mercury emission from this sector. A change in the annual emission of mercury from the household sector has been proposed and justified, assuming that the whole low-stack emission of mercury is the result of coal combustion only.

Opis:: Najważniejszymi źródłami emisji rtęci w Polsce, obok procesów spalania w sektorze produkcji i transformacji energii oraz przemysłu chemicznego, są wydobycie i przeróbka węgla kamiennego. Wiedza o zawartości rtęci w węglu oraz odpadach górniczych i transferze tego pierwiastka w cyklu życia węgla kamiennego (od wydobycia do deponowania odpadów), może przyczynić się do optymalizacji zarządzania zasobami naturalnymi i gospodarką odpadami. W niniejszym artykule przedstawiono wyniki badań laboratoryjnych zawartości rtęci w węglu kamiennym oraz w odpadach towarzyszących jego wydobyciu i przeróbce. Zaprezentowano także bazę danych dotyczącą zawartości rtęci w próbkach węgla surowego oraz próbkach przemysłowych.
Mining and processing coal are the most significant sources of mercury emissions in Poland, next of combustion processes in the production and transformation of energy and chemical industry. Knowledge of the mercury content in coal and mining wastes and the transfer of this element in the "life cycle" of coal - from mining to waste deposit can help to optimize the management of natural resources and waste management. In this paper the merits of undertaking research on qualitative and quantitative mass flux of mercury from the start of the element of the natural geological deposits. It also presents the results of the first phase of laboratory tests for determining the mercury content of coal and associated mining waste and the carbon conversion of the best currently available technology in this field.

Opis:: Artisanal and small-scale mining (ASM) - small sized, largely unrecognized, rudimentary, and an informal form of mining - occurs in more than 70 countries around the world and is mainly hailed for its socioeconomic benefits and reviled for its environmental devastation. As a result, many people are confused about the future of ASM. In Ghana, the government banned ASM in 2017 and formed a security taskforce drawn from the military and police to crack down on nomadic and local ASM workers who defy the ban. This approach is unsustainable, deals less with the fundamental problems, and increases poverty among the already impoverished local populations who depend on this type of mining as their only means of livelihood. To support the argument for sustainable reforms, revenue growth decomposition and growth accounting analyses were performed to determine the factors shaping ASM revenue over 25 years (1990-2016). Results show that production (gold output) is the most important factor that influences revenue growth from ASM, contrary to the usual view that the price of the metal is mainly responsible for the increase in revenue. Thus, increasing labor hours in ASM could significantly increase mining revenue, reduce unemployment, and improve local commerce. We strongly conclude that sustainable reforms such as increasing local participation in decision making, education and training, adoption of improved technology, strengthening regulatory institutions, legislation and enforcement of enactments, and the provision of technical support and logistics could ensure socio-environmental sustainability.
