Physicochemical limnology of Lake Kubanni, Zaria-Nigeria

摘要

The quality of any water body is governed by its physi-cochemical factors. The monitoring of physicochemical characteristics of a water body is vital for both long term and short analysis (Wood, 1995). Distribution and productivity levels of organisms are largely determined by physicochemical factors (Ashton and Schoeman, 1983; Adakole et al., 1998). The direct effect of interactions of many frequently measured water quality parameters with biotic components that affect productive potentials of fish species have been demonstrated (Kemidirin, 1993; Adakole etal., 1998; Adakole, 2002). Kubanni lake, constructed primarily for domestic water supply, receives various domestic and agricultural effluents through its major tributary (Samaru stream) and this could affect the water quality. Variations in physicochemical parameters of a water body could significantly influence the water's treatment processes, portability of the water supply as well as have long term effects on the biota in the aquatic environment (WHO, 1971; Adakole et al., 1998). The objective of the present study is therefore to investigate the physicochemical variations of lake kubanni and its tributaries.
