“…On average, mining requires around 0.4 to 1 kg of explosives to crush one ton of rock prior to mineral extraction [74,75]. Mining explosives are made up of chemical mixtures that produce pressure (over 2000 bar), heat (over 3000 K), and gasses that generate waves to crack and break rocks at different speeds depending on the type of rocks and minerals being extracted [75,76].…”

“…Detonation of mining explosives uses mixtures such as ammonium nitrate -fuel oils (AN-FO), Amonex-1, and Majdanit 10, which produce high quantities of carbon monoxide and nitrogen oxides (mainly NO 2 ) as their byproducts, amongst other chemicals and gases [76,77]. AN-FO are low-cost N-based explosives commonly used in both pit and open cast mines; they contain 94.5% ammonium nitrate (NH 4 NO 3 ) and 5.5% fuel oil, which are delivered separately and only mixed at the mining site prior to denotation, hence a great contributor to N contamination [78].…”

Freshwater is a scarce resource that continues to be at high risk of pollution from anthropogenic activities, requiring remediation in such cases for its continuous use. The agricultural and mining industries extensively use water and nitrogen (N)-dependent products, mainly in fertilizers and explosives, respectively, with their excess accumulating in different water bodies. Although removal of NO3 from water and soil through the application of chemical, physical, and biological methods has been studied globally, these methods seldom yield N2 gas as a desired byproduct for nitrogen cycling. These methods predominantly cause secondary contamination with deposits of chemical waste such as slurry brine, nitrite (NO2), ammonia (NH3), and nitrous oxide (N2O), which are also harmful and fastidious to remove. This review focuses on complete denitrification facilitated by bacteria as a remedial option aimed at producing nitrogen gas as a terminal byproduct. Synergistic interaction of different nitrogen metabolisms from different bacteria is highlighted, with detailed attention to the optimization of their enzymatic activities. A biotechnological approach to mitigating industrial NO3 contamination using indigenous bacteria from wastewater is proposed, holding the prospect of optimizing to the point of complete denitrification. The approach was reviewed and found to be durable, sustainable, cost effective, and environmentally friendly, as opposed to current chemical and physical water remediation technologies.

“…The first step in this process is a procurement of raw material for further processing and transformation. [18] Large amount of lignite makes possible a certain level of energy independence on one side, while on the other side3, the negative effects of reliance on lignite must be taken into account. The Thermal Power Plants "Kosovo A" and "Kosovo B" operate according to the outdated environmental standards, thus producing the high emissions of harmful gases which, consequently, greatly affect the environment and human health.…”

The objective of this paper is to point out the significance of the natural lignite resources in the region of Kosovo and Metohija and to consider their influence on the environment of the said part of the territory of the Republic of Serbia. The region of Kosovo and Metohija is extremely rich in lignite. It makes up 76% of the total coal reserves in Serbia and it is the third biggest region in Europe regarding the coal reserves. Lignite is burned in the existing thermal power plants in Kosovo and Metohija, and the construction of the additional blocks is being planned at the moment. Lignite reserves are so immense that on one hand they enable the energy independence, but on the other hand the overall negative impact of reliance on lignite must be taken into account, especially since the existing thermal power plants operate according to the outdated environmental standards, producing large emissions of air pollutants (harmful gases resulting from lignite combustion in thermal power plants) that have negative impact on health. In order to reduce the environmental pollution that such thermal power plants create, operating of the said power plants needs to be adjusted to the stricter standards in compliance with the legal requirements and the Industrial Emissions Directive of the European Union.
