Bioaccumulation Assessment Of Polycyclic Aromatic Hydrocarbons (PAHs) Distribution In Commonly Consumed Food Crops In Industrialised Site Located At Osisioma Aba, Abia State
ABSTRACT
This study investigated the concentration of
PAHs bioaccumulation in soil and selected commonly consumed fruits;
orange(Citrus sinensis), pawpaw(Carica papaya),star apple(Chrysophyllum
albidum),vegetables; fluted pumpkin(Telferia occidentalis), waterleaf(Talinum
triangulare), bitter leaf{ Vernocia amygdalina),tubers; yam(Dioscorea
spp.)cassava(Manihot esculenta),cocoyam(Colocacia
antiquorum),nuts;coconut(Cocos nucifera),palm kernel nut(Cola acuminate),and
kolanut(Cola acuminate) collected from an industrialized site located at
Osisioma Ngwa in Aba, Abia State Nigeria, PAH are organic compounds formed by
two or more fused aromatic rings originating from natural and anthropogenic
sources, such as incomplete combustions, industrial incinerations, transport,
or controlled spills. Twelve selected food crops and soil were analyzed and the
concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined
.The total concentration of 16 polycyclic aromatic hydrocarbons was found to be
59.32 mg/kg and 13.00mg/kg dry weight in analyzed food samples and soil
respectively. The highest level of total PAHs was detected in star apple
whereas the lowest concentration was found in cassava. Yam, cocoyam, coconut,
kola nut and pawpaw were below detection limit. Fruits and vegetables may have
high affinity for a variety of PAHs compared to tubers and nuts .The average
values for the estimated daily intake of B(a)peq across age groups were
significantly above the DPR intervention limit of 0.01. The LMWPAH/HMW-PAH
ratios observed from this study was
0.0
