Physicochemical Parameters of River Water and their Relation to Zooplankton: A Review

Abstract

Abstract Rivers are dynamic systems that respond to various physicochemical characteristics. In this review, we focused on the most important physicochemical parameters that influenced zooplankton composition and diversity in the rivers, including water temperature, dissolved oxygen, biochemical oxygen demand, hydrogen ion concentration, electrical conductivity, salinity, total dissolved solids, total suspended solids, turbidity, total hardness, calcium, magnesium, total alkalinity, bicarbonate, phosphate, nitrate, sulphate, and water velocity. As well as, we define these environmental factors and determined the minimum and maximum values for each factor. In general, we can be concluded that physicochemical factors that exceed standard values affected negatively on the zooplankton composition and diversity.
