ASSESSING THE DEPOSITION AND REMOBILIZATION BEHAVIOR OF METALS BETWEEN RIVER WATER AND RIVER SEDIMENT USING PARTIAL LEAST-SQUARES REGRESSION

Partial least squares regression (PLS) as a method for multivariate da ta analysis has been applied to environmental data of the German river s Saale, Ilm and Unstrut. Main aspects of the study are to describe th e relationships of the distribution of metals between river water and river sediment using PLS, A simulation of the distribution of metals b etween the liquid and solid phase by variation of some parameters (e.g . conductivity, DOC, dissolved oxygen, pH, phosphate and suspended mat ter) is presented and compared with experimental results.
