Aspects of Physico-Chemical Parameters of Bodna River in Kwali Area Council Abuja, Nigeria

Abstract

<jats:p>In this study, the Bodna River was analyzed for some physicochemical parameters. The main aim of the study was to determine the effect of human activities on the physical, chemical and biological properties of the river, and to enhance systemable usage for conservation and management. The water quality parameters examined were Temperature, pH, Transparency, Salinity, Total dissolved solids (TDS), Dissolved oxygen (DO) and Electrical Conductivity (EC) for the four sampling stations from May 2018 to April 2019. There was no significant difference (p&gt;0.05) in the pH values of the river ranging between (7.16 to 7.20) in all the sampling stations. The Analysis of Variance (ANOVA) showed significance differences (p&lt;0.05) in other parameters across the months. The result showed that air temperature ranged from 32.10±0.73 to 36.15±0.17 oc, water temperature from 30.20±0.94 to 34.30±0.22oc, transparency ranged from 5.9±0.61cm to 18.7±6.17cm, Salinity varied 2.08±0.06 to 3.15±0.50 mg/l. Total dissolved solid (TDS) was between 33.50±7.91 and 83.85±21.06mg/l. Dissolved oxygen (DO) ranged from 6.23±0.05 to 8.28±0.10 mg/l and Electrical conductivity (EC) ranged from 40.00±4.32 to 87.25±19.97ꭒ/s. The parameters were correlated within the stations. The results from the study showed that most of the physicochemical parameters were within the accepted values for consumption, biodiversity, productivity, domestic usage and are below pollution level.</jats:p>

Determination of physicochemical parameters and heavy metals content of water samples from domestic and Kaduna River in Kaduna Metropolis, Kaduna State

“…The DO value (1.18-8.55 mg/l) recorded from water sampled from domestic and Kaduna River, this could be attributed to aquatic insects and fish that live in streams and river gained oxygen from the atmosphere and plants as a result of photosynthesis (Oduor, 2000). This is similar with the work of Sani et al, (2019) that reported dissolved oxygen of 8.28mg/l of water samples from Bodna River in Kwali. There are physical factors that can lessen the amount of oxygen dissolved in the river.…”

“…There are physical factors that can lessen the amount of oxygen dissolved in the river. High temperatures which may result from high turbidity, from the return of domestic used water to the river decrease the amount of gases that can be dissolved in water (Sani et al, 2019).…”
