Study on Heavy Metals Levels and Some Physicochemical Parameters of a Polluted Creek along the Tin Can Island In Lagos (Published)
The study was carried out to assess the level of selected metals and physico-chemical parameters of a polluted creek along the Tin Can Island in Lagos. Metals such as Cu, Fe, Zn, Pb, Cd, Mn, and Cr were analysed using Atomic Absorption Spectrophotometer. Correlations analysis was conducted to determine the spatial distribution of the metals. From the results, it was evident that accumulation of heavy metals was within the internationally acceptable standards as reported by WHO and EPA. There was significant difference (p<0.05) between the physicochemical parameter across the different stations and months. Although conductivity (11060.5±6.4), TDS (2328.33±3.04) and BOD (107±52.0) were higher than the recommended limit of these metals by WHO which could be attributed to large amount of deposited and sewage floating at the banks of the creek. However, if these levels are not checked, they may increase the potential of bioaccumulation in the aquatic organisms and inhabitants that depends on the creek for survival. Therefore, there is need for policies to conduct regular monitoring of this creek to avoid future deterioration of the creek.
