Özet

Inorganic metals besides their direct toxic effects, carry the potential of causing serious variations on existing ecosystems in receiving waters A selfpurification mechanim is vital for the continuity of the existing micro and macro living organisms in the streams. This mechanism is effected from the existence of met.als In this study, interferences of HgCl2, HgSO4, CuSO4.5H(2)O, K2Cr2O7,ZnSO4.7H(2)O and Al-2 (SO4)(3).18H(2)O metal compounds on respirometric BOD and related effects on the self purification, were investigated with representative formations of Sag curves. In the presence of these metals, streamwater BOD parameters and the related Sag curve formations were significantly effected.
