Physical-chemical water quality study of the Sava River in Serbia using the statistical and factor analysisPantelić, Milana ...Based on selected parameters, this paper aims to assess the physical-chemical water quality (PCWQ) of the Sava River in a part of the streamflow through Serbia, for the period 1997–2016. The ... spatio-temporal variations of surface water quality were determined by using One Way ANOVA, Pearson Correlation Index (PCI), Principal Component Analysis (PCA) and Confirmatory factor analysis (CFA). Water quality was assessed according to national and international water quality criteria. The parameter values are mostly within the permitted limits, however, on few stations, they were found to exceed the criteria levels. Better water quality was registered during the colder periods of the year. Also, better water quality was registered at SSt Šabac compared to SSt Jamena and SSt Ostružnica. PCI analysis shows a negative correlation between the T and DO and a positive correlation between the EC and PO4-P. The PCA defined four main components that determine the greatest impact on the temporal change of water quality. These are seasonal factors, eutrophication, sediment pollution and organic pollution. As shown in the algorithm results, as long as the covariance curve is included in the four factors, no related issues are detected in the goodness of fit of reflective indicators and interior and external quality is reported with excellence. The orthogonal model, thus, stands. The seasonality factor was dominant but it has been established that the pressures in the Sava River Basin exist, and there are most pronounced through the point sources of pollution.Source: Water resources. - ISSN 0097-8078 (Vol. 49, no. 6, 2022, str. 1048–1058)Type of material - article, component part ; adult, seriousPublish date - 2022Language - englishCOBISS.SI-ID - 133785603
