“…The town is home to many medium scale industrial clusters in Southeastern Nigeria [9] that produces automobile, petrochemicals, metals, paints, electric wires, cables, car battery, vegetable oil, soap, plastic tanks, and animal feeds [10] , [11] . These industrial activities have been reported to be responsible for polluting the surrounding land surface in Nnewi [9] , [12] , [13] . Also, these unbridled human activities, including borehole water pumping, industrial emission of heavy metals, and poor waste handling, have led to significant water pollution in the region [14] .…”

A physicochemical profile study on the soil along the banks of the Ubu river that runs across Ekwusigo and Nnewi Local Government Areas (LGA) of Anambra State of Nigeria was investigated for possible evidence of industrial waste disposal by the various large to medium scale industrial activities taking place within the two LGAs. When compared with soil samples from Uzoakwa Ihiala (pH 5.44) with little or no industrial activities, the soil along the banks of the course of the river were found to be more acidic with mean pH values that are lower than 4.7. Similarity in mean sulphate (7.01 mg/kg), phosphate (12.95 mg/kg) and chloride (242 mg/kg) contents was observed between the soils from the banks at Nnewi with those of the Uzoakwa Ihiala that was used as control. This was attributed to contributions from domestic sources rather than from industrial sources, and partly to the similarity of their soil chemistry that may be indigenous to both areas. Electrical conductivity values (55 -74 microS/cm) show that the ionic content of the soil is lower than those of the control (129 microS/cm). This may have been explained by the higher extractible Ca (175.73 mg/kg), K (34.32 mg/kg), and Mg (1.94 mg/kg) recorded for the control. The abundance of the metals extractible from the soils of the river banks follow the sequence Ca>K>Na>Fe. Results for the digested soil samples show that Fe is the most abundant metal in the soil with mean values that are close to 13,000 mg/kg, but is much lower than the mean value of 39,210 mg/kg recorded for the control. Both bank and control samples can be characterized as ferrous. The relative abundance of metal ions observed in the digested soil samples from the river banks follow the sequence Fe>>Al>Ca>Na>K>Zn>Cr. Values of 4,565 mg/kg and 300 mg/kg were recorded for total hydrocarbon content and lead respectively for soils around Cento Group, indicating that there were industrial waste disposal or spillages on soil around the area, which was not observed in other areas.

Today, industrialization has been implicated in the generation of certain compounds which are potentially hazardous to human life. This is a cross sectional study designed to evaluate some heavy metal levels in blood of lead acid battery manufacturing factory workers in Nnewi, Nigeria. A total of 39 apparently healthy individuals in lead acid battery manufacturing factory aged between 19 and 56 years and 79 control individuals (comprising of 39 control individuals from Nnewi (N) and 40 control individuals from Elele (E) respectively) aged between 18 and 44 years were recruited for the study. Demographic data and body mass index (BMI) of participants were obtained using structured questionnaire and thereafter, 5ml of venous blood sample was collected from each individual for the evaluation of heavy metal levels (Pb, Ni, Cu, Zn, As and Se) using atomic absorption spectroscopy (AAS). Results showed that the factory workers had an average length of service (LOS) of 7.70±0.86 years and BMI which did not differ significantly when compared with the control groups (control N and E individuals) respectively (p>0.05). However, elevated levels of Ni, As and Pb and decreased levels of Cu, Zn and Se were observed in the blood of the factory workers compared with control N and E individuals respectively (p<0.05). Therefore, this study has shown that these individuals may be prone to heavy metal toxicity and possible depletion on some vital micronutrients which may have grave health consequences for individuals dwelling in this area.
