Assessment of Struma river water quality using correlation analysis
2007
Dyadovski, I. | Atanasova, M. | Simeonov, V.
A model for assessing the Struna river pollution by the use of correlation analysis of water quality basic indicators is proposed. This assessment was made for the background and reference points of the Bulgarian section. The time period of 1990-2005 is considered. The Struma pollution assessment is based on the correlation matrix of 20 chemical indicators for this period. The correlation analysis of water quality indicators was made using information from the National Ecological Monitoring Network. The general correlations among the water pollution parameters are calculated with the help of the Programme Struma Software. Three factors are characterizad by the data set structure.
