Physicochemical parameters of the s

Physicochemical parameters of the study sites were collected on sites and include water temperature using hand mercury thermometer, pH using a pH meter, conductivity and total dissolved solid using a conductivity/TDS meter, turbidity
using a spectrophotometer (HACH model DR/2000) by the absorptometric method, water alkalinity by phenophthalein methyl orange indicator method, dissolved oxygen and biochemical oxygen demand (BOD5) by the azide modification method, nitratenitrogen, ammonia-nitrogen and orthophosphate using a spectrophotometer (HACH model DR/2000) by cadmium reduction method, Nessler method and
ascorbic acid method, respectively.
