Public Health Implications of Some Heavy Metals Contained in Palm Wines of Wilberforce Island Area, Nigeria
Abstract
This study evaluated the heavy metals hazard of palm wine from Raphia species sold in Wilberforce Island, Bayelsa State Nigeria. Triplicate samples were obtained from six locations in Wilberforce Island and analyzed using atomic absorption spectrophotometer. The health risk associated with heavy metal contaminants was calculated following standard protocol. Results of heavy metals in palm wine were in the range of 0.157–0.319mg/L, 0.554–0.983mg/L, 0.000– 0.2289mg/L, and 0.123–0.5299mg/L for zinc, iron, cobalt, and copper respectively. There were significant discrepancies (p < 0.05) in the palm wine samples across various locations for the different parameters. Metals such as cadmium, chromium, nickel, and lead were not detected in palm wine, indicating that toxicity related to them is nonexistent. However, zinc, cobalt, and copper were observed at low concentrations, while iron levels exceeded regulatory comparison. This is possibly an indication of iron-rich soils which are prevalent in the area. It may also have resulted from activities releasing this metal within the study area. Average daily intake and hazard quotient and health index (< 1) indicate no adverse acute health effect. To forestall potential health risks associated with heavy metals in palm wine, there is a need to regularly evaluate heavy metal concentrations.
