title: Phytoplankton as index of water quality with reference to industrial pollution.
abstract: In this paper Shannon-Weaver (SI-3.58-4.07, SII-3.1-3.72, SIII-1.64-2.25, SIV-2.54-2.95 and SV-3.09-3.23) diversity index was applied to surface phytoplankton to study the water quality status of river Bhadra receiving Mysore paper mill and Iron and steel mill effluent. A total of 45 species of phytoplankton belonging to 5 classes were recorded and study indicated that the phytoplankton diversity (Chlorophyceae-19 species, Bacillanophyceae-16 species, Cyanophyceae-07 species, Euglenophyceae-2 species and Chrysophyceae-1 species) did not reveal the same type of water quality (water temperature 24.62-27.32 degrees C, pH-7.08-7.25, electrical conductivity-67.49-201.94 micromhos/cm, dissolved oxygen-4.13-5.98 mgl(-1), chloride-12.30-40.85 mgl(-1), calcium-6.49-23.74 mgl(-1), total hardness 28.98-76.65 mgl(1), magnesium-4.69-15.92 mgl(-1), total alkalinity-77.26-86.53 mgl(-1), BOD-1.88-4.01 mgl(-1), COD - 16.53-45 mgl(-1), phosphate-0.001-0.53 mgl(-1), sodium-2.70-7.46 mgl(-1) and potassium-2.37-7.88 mgl(-1)). The investigation emphasized the need of phytoplankton community as index of water quality polluted by industrial effluents at the downstream stretch of the Bhadra river.
