Abstract:



Purpose.
To reflect the impact of discharge waters from the ferronickel smelter and surface lignite mining on the pollution of the Drenica River with heavy metals. According to our estimation, the effect of mining on the river pollution is undeniable.


Methodology.
The standard methods ISO 5667-6, ISO 5667-11, and ISO 5667-1.3 were used to determine the physical and chemical parameters of the Drenica River surface water. The EPA-3015A method was applied for sample preparation, while the AAS (Atomic Absorption Spectrophotometry) measurement technique was used to determine the concentration of heavy metals. Standard ISO methods were applied for determining the following parameters: pH, DO, BOD5, COD, NNH4, NO3-, TN, PO4P, and TP.


Findings.
From the obtained results, it can be concluded that the levels of heavy metals in the river Drenica have exceeded the allowed values as a result of industrial activities.


Originality.
The paper supplies new additional information on the ecological status of the Drenica River, based on samples taken along the river, especially where the greatest impact of the ferronickel smelter and surface lignite mining could be. The problematic of this research is quite contemporary; river pollution affects the life chain.


Practical value.
We believe that the content and problems in the focus of the research are topical and present significant interest to all those who deal with environmental issues.
