TRANSLOCATION CONCEPT OF HEAVY METALS IN PLANTAIN CONSUMPTION CHAIN OF CRUDE OIL IMPACTED COMMUNITY IN BAYELSA STATE NIGERIA
This study was conducted to assess the concentrations of some Heavy Metals (HM) and their translocation capacity in the various milieus of plantain cultivation-consumption chain using a rabbit as an animal model. Twelve male albino rabbits divided into control and treatment groups constituted the sample size. Both groups were fed with normal rabbit meal void of detectable HM, except for the treatment that plantain harvested from Imiringi Bayelsa State was included. Heavy metals (Cr, Pb, Cd, As, Hg) concentrations were estimated using AAS in soil, plantain, and serum, and vitreous of the groups. Data analysis was carried out using Student-tests on the SPSS version 22 package. Cadmium, chromium, arsenic, and mercury concentrations were significantly increased (p<0.05) in plantain cultivated soil when compared to the plantain. The concentrations of vitreous cadmium and lead were significantly elevated (p<0.05) in the treatment group when compared to the control group, whereas vitreous chromium was vice versa. Similarly, serum cadmium and chromium significantly decreased (p<0.05) in the treatment group when compared to the control group, whereas serum lead concentration increased. The study has shown that heavy metals have the preponderances of bioaccumulation and translocation in studied body fluids.
