  The antioxidative and anti-fungal effects of ginger oil on smoked Chrysichthys nigrodigitatus, Clarias gariepinus and Oreochromis niloticus were examined during five week storage at room temperature 25-30°C. The ginger oil was extracted from fresh ginger through hydro-distillation. The fish samples were gutted washed thoroughly and each fish species were divided into three groups. Two groups were spiced with 1.0 and 1.5 mL of ginger oil/kg of fish, respectively before they were smoke dried for 2 h. The third group acts as the control which was not spiced with ginger oil. Chemical and microbiological analyses were performed to investigate quality changes and to determine the shelf stability of the products. The lowest TBA (14.64 mg MDA kg-1) and peroxide (3.91 mEq kg-1) values were recorded in Oreochromis niloticus samples treated with 1.5 mL ginger oil/kg of fish at week 1, while the highest TBA (30.48 mg MDA kg-1) and PV (18.76 mEq kg-1) occurred in the Clarias gariepinus control at week 5. The result also revealed that samples treated with ginger oil had lower mould count than the control but there was no significant different (p≥0.05), when compared to the control after 5 weeks of storage.

  This study was carried out to investigate the ability of water hyacinth (Eichhornia crassipes (Mart.) Solms.) to absorb and translocate iron (Fe) and copper (Cu). The study was conducted with three concentration gradients of Fe and Cu at 10, 15, 20 mg L-1 and control (no metal). The whole set-up was carried out in triplicate and the experiment lasted for 12 weeks. The results showed that iron (Fe) had the highest accumulation value in the root (11.22±6.69 mg kg-1), while copper (Cu) had the highest value in the leaf (3.80±0.12 mg kg-1) both occurred at treatment spiked at 20 mg metal/L of water. Statistical analysis showed that there was significant difference (p<0.05) in metal accumulation among treatments. The Translocation Factor (TF) values for Fe ranged from 0.49±0.57 to 0.68±0.27 in leaf and 0.64±0.17 to 0.77±0.18 in the stem while the TF values for Cu ranged from 0.78±0.08 to 1.12±0.12 in leaf and 0.72±0.32 to 1.09±0.19 in the stem. This reveals that Cu had better translocation capability than Fe. Highest values of Bioconcentration factor (BCF) for Fe and Cu were 2.32±0.65 at 20 mg L-1 and 0.72±0.01 at 15 mg L-1 obtained in the root and leaf respectively, indicating that the accumulation potential of Fe by water hyacinth is higher than Cu. So, according to the accumulation capabilities of the investigated plant (Eichhornia crassipes), this study showed that the plant was found to be a promising candidate for phytoremediation and adequate for bio-monitoring programmes for contaminated water.
