Polycyclic Aromatic Hydrocarbons (PAHs) and some Trace metals in Yam, Cassava, Orange and Papaya from two Oil and Gas Flaring Impacted Communities in Southern Nigeria
NWAICHI, EO; AGBAM, P & IWU, PI
Abstract
The present investigation provides data on the levels of PAHs and trace nutrient elements in selected
tubers (yam and cassava) and fruits (orange and papaya) harvested from oil impacted and gas flaring areas in Akalaolu
and Ogale Niger Delta communities. PAHs and heavy metals concentrations were analysed by Gas Chromatography and
Atomic Absorption Spectrometry. Akalaolu samples gave (mg kg-1 PAHs) 4.321, 2.934, 19.003 and 7.004 while Ogale
samples gave 3.445, 3.200, 5.41, 0 and 5.021 for cassava, yam, papaya and orange respectively. All selected fruits and
tubers collected from the two sites contained significantly decreased trace nutrient elements and signal deficiency
conditions. These findings suggest that study food crops from exposed areas are markedly contaminated by carcinogenic
PAHs and may pose public nutrition and health concerns. Also, determination of trace nutrient elements in papaya at
contaminated sites showed that papaya markedly accumulates metals in response to contamination.
Keywords
