ENVIRONMENTAL RISK ASSESSMENT OF FERIZAJ REGION

Water is the most common substance in the composition of all living beings. It’s required to meet our basic needs in daily life, cooking, drinking, bathing, disposal of sewage, irrigation, generating electricity in power plants, cooling etc. Municipal wastewater is the outflow that comes from households, offices, laundries, hospitals, and small industrial plants. This wastewater typically contains human and other organic waste, nutrients, pathogens, microorganisms, suspended solids, household and industrial chemicals not removed. The water pollution in Kosovo is an important problem because of the wastewaters from inhabited areas is discharged in the nearest rivers without previous treatment. The Kosovo Rivers in a daily basis are becoming more polluted by endangering the existence of the vegetal and animals in the same time while affecting pollution of the fertile land of direct or indirect manner. Same fate has the Nerodime River, which derives into the village Nerodime of Ferizaj city. The main purpose of this work was the qualitative and quantitative study of organic, inorganic and trace heavy metals and to evaluate the ecological state of water at the Nerodime river. Standard procedure for examination of wastewater was used to mark organic and inorganic compounds. The experimental results show that wastewater discharged from the municipality of Ferizaj to the Nerodime River, contains small value of OD, high value of: COD, BOD5, fats and oils, proteins, carbohydrates, trace amounts, of priority pollutants and surfactants. To adequately protect public health, the safety of wastewater discharged to a receiving stream must be ensured.
