“…reported concentrations ranging from 52 to 74 mg kg-I dry weight in benthic algae from the River Neckar (FRG), while in the River Leine (FRG) and Danube River (Austria), there was a range of3.0 to 288 mg kg-I Rehwoldt et al, 1975). Substantially higher levels (150-700 mg kg-I) occurred in algae inhabiting water adjacent to a UK smelter (Trollope and Evans, 1976).…”

“…Many scientific projects focused on the research of the rivers are limited to the shorter periods of time of just a few months or at best a few years. They cover wide range of topics such as analysis of eco-chemical status (e.g., van Dijk et al 1994), river biota (e.g., Subotić et al 2013), exploration of spatial and temporal variations and trends (e.g., Hamilton et al 2011;Skidmore et al 1998), and/or influence of the tributaries (e.g., Hinck et al 2007;Paller et al 2004), cities, or artificial structures such as dams (e.g., McGinnis et al 2006;Rehwoldt et al 1975;Takao et al 2008). These approaches are assumed to be reasonable, especially if the resources for the research are limited, because the period of 1 year covers all seasonal changes.…”

We have assembled and assessed the statistical procedure which is capable to objectively explore influence of the Danube's major tributaries (the Rivers Tisa, Sava, and Velika Morava) to its eco-chemical status. Procedure contains several tests for measurement of central tendencies: one-way analysis of variance (ANOVA), repeated measures ANOVA, and nonparametric Kruskal-Wallis and Mann-Whitney tests. Various nuisance factors, (outliers, departures from normality, seasonality, and heteroscedasticity) which are present in large data bases, affect the objectivity of central tendency tests; therefore, it was important not only to estimate their robustness, but also to apply proper procedures for detection of the nuisance factors (Grubbs', generalized ESD-extreme Studentized deviate, Kolmogorov-Smirnov, Shapiro-Wilk, turning point, Wald-Wolfowitz runs, Kendall rank, and Levene's tests) and to mitigate their influence (outlier exclusion, Box-Cox, and logarithmic transformations). The analysis of selected eco-chemical parameters: biological oxygen demand-5, chemical oxygen demand, UV extinction at 254 nm, dissolved oxygen, oxygen saturation, total dissolved solids, electrical conductivity, suspended matter, total phosphorus, phosphates, nitrates, ammonia, pH, total alkalinity, m-2p alkalinity, CO2, and temperature, was performed for 15 years period. The Tisa was the most polluted tributary, but its pollution load was not substantial enough to exceed the Danube self-purification potential. The City of Belgrade was also identified as serious pollution source. Assessment of assembled statistical procedure, which was based on the real environmental data, indicates that proposed tests are sufficiently robust to the observed level of nuisance factors with the exception of pronounced seasonality.
