Özet

During May 2002- April 2003, 72 field works were done on 6 sampling points at Dariören stream basin (Isparta/ Turkey). Ecological methodologies (species richness, diversity and saprobic indices, as well as multivariate analysis) were employed to assess the impact of the pollution on epilithic diatom assemblages. Biological oxygen demand, NH4-N, NO 3-N, NO2-N SO4, conductivity, total hardness and turbidity parameters were increased, pH was variable, but dissolved oxygen was decreased at the 5th and 6th sampling points of the stream, which were affected by organic and inorganic pollutants. Changes in water quality levels were better reflected by saprobic index and by principal component analysis than species richness and diversity indices in the Dariören stream. © by PSP.
