Effect of petroleum waste water on new Calabar River and its sediment in Buguma, Rivers State of Nigeria
Abstract
Effect of petroleum waste water on New Calabar River and its sediments in Buguma, Rivers State of Nigeria, was investigated. Water and sediment samples were taken upstream; point of waste water discharge, and
downstream 1 and 11. Some physico-chemical properties [pH, temperature, turbidity, conductivity, and salinity] were determined using standard methods, and results showed significant increase in these parameters at the petroleum waste water discharge point, compared to the upstream and downstream points. Water analysis results also showed
that Biological Oxygen Demand (BOD), Total Dissolved Solid (TDS), Total Suspend Solid (TSS) was significantly increased. However cation and anion components Calcium, Sodium, Magnesium, Potassium and nitrate, sulphate and phosphate were not significantly (p>0.05) affected. Microbial load were also significantly reduced at the discharge point. The results indicate that the petroleum waste water adversely affected the water quality at the point of discharge into the river and by extension the aquatic organisms of the river. The probable effects of these findings on human life and the environment are discussed.
