  Abstract: This study reports the investigation of seasonal variation of air quality measures in Owerri Metropolis and Isiala Mbano L.G.A in Imo State. Parameters such as NO2, CO, Cl, SO2 and TPM were monitored in air samples during the dry and rainy seasons using a portable gas analyzer and particulate matter analyzer for the gases and TPM respectively. Water samples were collected from open air and were analyzed for heavy metals …

  Abstract: The effects of pollution on water have been reviewed. This study is aimed at determining the level of pollution of the River Benue, with the view of assessing its use as potable water. Different analytical techniques including titrimetry, gravimetry, potentiometry, and spectrophotometry were used for the study. The total hardness gave (22.28 mg/L and 41.87 mg/L) for dry and rainy season respectively. Electrical conductivity gave (91.35 mg/L and 54.10 mg/L) …
