Chicken meat is classed among one of the major sources of animal proteins and still enjoys global acceptance to date without recourse to their heavy metal residues. Hence, this study investigated the heavy metal residues in raw chicken meat and the associated health risk via consumption within major markets in southern Nigeria. A total of 240 raw chicken meat samples (muscle tissues) were purchased randomly from Warri, Akure, Ado-Ekiti and Benin City markets. After ashing, digestion and heavy metals analysis for Pb, Cr, Cd, Mn, Ni, Zn and Cu using standard atomic adsorption spectrophotometer, the target hazard quotient (THQ), health risk index (HI) and daily intake index (non-carcinogenic risk) and incremental cancer risk in children and adults were determined. The mean heavy metals ranged from 0.001 ± 0.001 mg/kg (Cr) to 2.094 ± 0.001 mg/kg (Zn) and varied significantly (P<0.05) with Warri samples (58.9 %) yielding the highest level, followed by Benin City (26.8 %), Ado-Ekiti (10.2 %) and Akure (4.2 %) samples. The non-carcinogenic risks (HR/HI) were substantially low for the metals studied in all the locations except for Cd, which could pose serious health risk among children in Warri location. However, the incremental cancer risk ranged from 10-4 to 10-3 in all the locations, suggesting at least a cancer case per 1,000 exposed people (both in children and adults). Considering the impending public health risks, critical hazards points of heavy metals contaminations along meat production chains should be properly identified to drastically reduce their potential risks to exposed consumers.

Food crops grown in contaminated soils have a greater accumulation of heavy metals and the consumption of food crops grown in the contaminated soils are the source of metals that enters into the human body. Rice being a major food crop, the presence of heavy metals should be monitored regularly for reducing health risk. The analysis of total heavy metal always overestimates the content which leads to misinterpretation of results; however, bioaccessible heavy metal analysis projects the actual health risk. Hence, the present study aims to assess the bioavailable form of heavy metals in rice. The rice samples were collected from 20 different places and used for the inherent and bioavailable metal estimation. In vitro simulated digestion method was applied for bioaccessible metal analysis. Metal concentration in polished rice ranged from 0.10 to 0.82, 0.10 to 1.07, 0.11 to 0.56 and 0.23 to 1.09 mg kg-1 for Lead (Pb), Nickel (Ni), Cadmium (Cd) and Chromium (Cr), respectively. Twenty five percent of the samples recorded less than 0.028, 0.01, 0.01, and 0.03 mg kg-1 of bioaccessible Pb, Ni, Cd, and Cr, respectively. A significant negative correlation was observed between total metal concentration and bioaccessibility percentage. Targeted Hazard Quotient (THQ) of all the metals were less than one for adults indicating that there were no health risks, which undoubtedly reveals the importance of bioaccessible metal analysis. Hence, regular monitoring of heavy metals is essential to reduce the intensive accumulation in the human food chain. Also, the present study has opened up a wide scope on human health risk assessment using an in vitro digestion model.

Abstract This study investigated the potential health risk due to dietary exposure to Polycyclic Aromatic Hydrocarbons (PAHs) for the populace living around selected industrial areas in the south eastern states of Nigeria. The concentrations of PAHs were measured in edible food crops using Gas Chromatography - Flame Ionization Detection (GC-FID). The mean concentration of PAHs in food crops collected ranged from < 0.01 to 2.64 ± 0.02, 5.27 ± 0.04, 0.96 ± 0.02, 8.94 ± 0.01 and 1.95 ± 0.06 in mg/kg for Osisioma, Ishiagu, Irete, Akwuuru, and Ngwo respectively. PAHs distributions in food samples analyzed in this study showed vegetables to be significant higher (p ≤ 0.05) in the order vegetables > fruits > nuts > tubers. Total PAHs (ΣPAHs) concentrations in most crop samples had highest values 14.49, 36.29, 4.59, 23.36 and 21.8 mg/kg for Chyrysophyllum albidum, Telferia occidentalis, Vernonia amygdalina, Talinum triangulare and Elaies guinnensis for Osisioma, Akwuuru, Irete, Ishiagu and Ngwo respectively. The low molecular weight-PAHS/high molecular weight-PAHS were < 1 with values 0.76, 0.18, 0.28, 0.91 and 0.12 for Osisioma, Irete, Akwuuru, Ishiagu and Ngwo respectively. 58.3% and 71.7% of ΣB(a)P and ΣPAHs in food samples in the study areas exceeded the permissible limits set by DPR and EU. The estimated daily intake of PAHs via the ingestion of food crops were within the tolerable range. The carcinogenic risk values for the food crops were within the predicted permissible lifetime risks of carcinogen (10−6-10−4) for adults and children in Osisioma, Akwuuru, Ishiagu and Enugu respectively. Therefore, this study suggests that the populace around industrialized areas in South Eastern Nigeria, may be at risk due to PAHs exposure through food consumption.
