Rapid socio-economic development and urbanization have contributed to the serious deterioration of air quality in many world cities including Pristina, the capital of Kosovo. Through a data-driven analysis of regulatory intervention, this study attempts to examine the effectiveness of air pollution control regulations that have been implemented in Kosovo between 2010–2021. Our results show that the measures enforced during this 10-year period in Kosovo, and particularly in the capital city, have resulted in the reduction of pollution. The applied methods for this research are the standard ones of the Instituti Hidrometeorologjik i Kosovës (Hydrometeorological Institute of Kosovo). All results showed a decrease of each pollutant over the ten years. These changes strongly indicated that the origin of the pollution was traffic and anthropogenic activity, while the power plant was considered to be a less significant source of pollution. The basic pollutants of air quality in Pristina are particulate matters (PM2.5 and PM10), ozone and nitrogen oxide.

The physicochemical parameters of water play an important role in determining aquatic life and its development. In this study, the water quality index is used in order to assess the water quality in river Lepenci River. For the calculations of this index, eighteen physicochemical parameters were analysed, which were measured in 3 years during the years 2009, 2010 and 2014 in three stations of the main flow of river Lepenci during all months of the years. From the results, it is concluded that the better quality of water was in station SP1- Brezovica with a WQI value of 83 and it belongs to the Good category, lower quality of water has been shown in station SP3- Hani Elezit with a WQI value of 53 belonging to the marginal category. The average value for all measurement periods resulted in 70.44 which has shown that the water quality of the river Lepenci, based on the physicochemical parameters, belongs to the Fair category. Based on these results, we conclude Water quality impairment is mainly associated with an increase in population, urbanization, industrialization, and agricultural production, among others, and the development of ecotourism and hospitality in high areas near the source areas.
