Air pollution is a global threat leading to large impacts on health and urban ecosystems.The air quality index is based on measurement of particulate matter (PM2.5 and PM10), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Carbon Monoxide (CO) and Ozone (O3). Recent the years in Kosovo are installed nation air quality monitoring in different areas such as residential areas, industrial, roadside and reference areas. The study was conducted in Prishtina region between November-December 2021 and January 2022 in five monitoring stationes. The purpose of this paper is to determine compliance with air quality limit value, to detect pollutant levels (NO2, SO2, CO, O3), particulate matter (PM10 and PM2.5) and to study the values of exceedances, from the standards values for air quality. Air quality monitoring in this study was done in the study area Agglomeration-AKS1 (IHMK, ex-Rilindja, Obiliq, Dardhishte and Palaj). Particulate matter (PM10) and (PM2.5) and Nitrogen Dioxide (NO2) have shown exceedancces value from the standard values for air quality in Agglomeration-AKS1area in Prishtina. Nitrogen Dioxide (NO2) have shown exceedancces value (100-120 μg/m3) from the standard values for air quality at the ex-Rilindja (132.2 μg/m3). PM2.5 has exceeded the limit values (20–25 μg/m3) in monitoring stations:IHMK,Obiliq, Dardhishte and Palaj. The respect and application of international standards for air quality strengthens the image of Kosovo, preserves the health of citizens, fulfills environmental criteria, while the contribution of the media is considered important.

Surface water pollution is mainly due to large urbanization, agricultural waste and discharges of production. The purpose of this study was to evaluate the pollutant parameters of surface waters effluents contaminated by synthetic detergents and organic chemical substances. During the study, the following physico-chemical parameters were analyzed: phosphate ion (PO43−), total phosphate (TP), sodium tripolyphosphate (Na5P3O10), sodium perborate (NaBO3n H2O ), ammonium (NH4+), nitrate (NO−3), nitrite (NO2−), water temp. (°C), and hydrogen ion concentration (pH). The correlation between the source water and the current level of pollution of this river was measured in four locations: (Prevalla L1 ; Reqane L2; City park L3; Vlashnje L4) along the surface course of the Lumbardhi River in Prizren. From the results of the study for both time periods, the chemical parameters values of phosphate ion (PO43−) for May, 2022 according to monitoring of physico-chemical parameters in Lumbardhi River in Prizren were 0.01. The value of total phosphate (TP) was 0.002, for sodium tripolyphosphate (Na5P3O10). The water quality of the Lumbardhi river directly depends on the amount of flows in the river. Poor quality of the water is more pronounced during the month of October, when the amount of flows in the river is smaller. Location (L3) had higher pollution as a result of the discharge of urban sewage and city waste. Research has shown the presence of different forms of phosphorus that are higher in the (L2 and L3) locations.
