The focus of this study is the determination of the heavy metals content of Teifera occidentalis grown in the Niger Delta oil producing areas. To achieve this, four oil producing communities were randomly selected from Niger Delta. Five research stations were also selected from the sub-settlements that made-up each oil producing community. Samples of edible portions of T. occidentalis were collected from five spots in each sampling station, bulked, a composite drawn, wrapped in absorbent paper and taken to the laboratory for analysis. The analytical standards adopted were USEPA and APHA and the analytical instrument deployed for the determination of the heavy metals concentration is Agilent atomic absorption spectrophotometer model 240A. The results obtained were as follows; Cu concentration is between 0.63mg/kg to 29.01mg/kg with the mean of 8.14±13.92; the concentration of Zn is between 1.20mg/kg to 36.61mg/kg with mean concentration of 10.86±17.18; Mn concentration is between 15.72mg/kg to 150.00mg/kg with a mean concentration of 63.89±60.55; the concentration of Co is between 1.68mg/kg and 6.40mg/kg with a mean concentration of 3.57±0.02mg/kg and Cr concentration between 0.00mg/kg to 22.03mg/kg and has a mean concentration of 5.65±10.82mg/kg. The results of the mean concentrations of the parameters were further subjected to test of significance with analysis of variance (ANOVA) with df numerator 4 and denominator of 15 at 0.05 level of significance. The F ratio calculated is 1.05 while F-ratio crit is 3.06. The study thus recommends that T. occidentalis should be produced and consumed in the Niger Delta oil producing regions.
