Environment & Ecosystem Science (EES)

Trace elements with bio-importance are presence in some heavy metals but adverse effects of these elements called for concern in human system. Hence, the parameters involved must be put into consideration, such as the environment, health effects, and concentrations. The occurrences of the substance to our immediate environment, leaching processing, and their sources must be known. It is generally known that these substances are input into our immediate environment by both natural and anthropogenic means. The substance are imported into the subsurface water, flowing through water directions and finally depositing in the aquifer, or transported by erosion and end up in water and subsequently soil pollution. Heavy metals concentration level presence in soil samples from transformer oil was determined in Sango and Orita-Challenge, Ibadan, Oyo State, Nigeria using Inductively Coupled Plasma (ICP). The heavy metals determined were: (Pd, Ni, Cd, Mn, Cu, Fe, Zn, Ca, Co, K, Mg, Na, and Cr). It was affirmed from the results that some high level of heavy metals concentration from the transformer sites differs from one another, as a result of heavy metals content in the transformer oil released to the surrounding soil, while the analysis of some samples shows that the heavy metals fall below the detection limit or absent.
