“…Consumers of these edibles should be particularly cautious of the excessive amount of carcinogenic PAH in EleleAlimini land snails and Ebubu pumpkins, having recorded the highest amount of carcinogenic PAH, and as such, are capable of producing significant health threats. More so, the total PAH and total carcinogenic PAH in all samples and locations in this study, exceeded the WHO recommended maximum permissible limit of 10 ppm [17]. Oxidative stress enzymes from snail and fish samples obtained from Ebubu and Elele-Alimini localities were presented in Table 3.…”

Abstract. This study was carried out to assess the levels of heavy metals, polycyclic aromatic hydrocarbons (PAHs), and antioxidants present in pumpkin leaf (Telfairia occidentalis), catfish (Clarias anguillarus), and African land snail (Archachatina marginata), obtained from Ebubu and Elele-Alimini communities in Rivers State, Nigeria. The heavy metals and PAHs were analyzed using Atomic Absorption Spectrophotometry (AAS) and gas chromatography respectively, while the antioxidants were assayed by conventional methods. Soil samples at Ebubu contained significantly higher Pb, Cr, Cd, and Ni contents than that of Elele-Alimini. The pumpkin leaf from Elele-Alimini contained higher Pb, Zn, Cd, and Fe levels. Cr was undetected in the snails from both locations, while Cd and Ni contents of the snails and catfish at both communities were comparable. For the PAHs, the soil samples from Ebubu contained mostly anthracene (93.37 ppm), benzo[k]fluoranthene (74.36 ppm), fluoranthene (72.64 ppm), and acenaphthylene (47.38 ppm), while those from Elele-Alimini contained more of dibenz[a,h]anthracene (38.65 ppm) and naphthalene (20.55 ppm). Pumpkin leaves from Ebubu were mostly composed of naphthalene, indeno[1,2,3-cd]pyrene, and dibenz [a,h]anthracene, which were undetected in pumpkin leaf samples from Elele-Alimini. In the snail and catfish from Ebubu, acenaphthylene and fluoranthene respectively were the most occurring PAHs, whereas pyrene and phenanthrene respectively had the highest occurrences in snails and catfish from Elele-Alimini. Results for the antioxidant enzymes: catalase and superoxide dismutase in both snails and catfish from Elele-Alimini were significantly higher than those from Ebubu whereas samples from Ebubu contained significantly higher glutathione and malondialdehyde levels. The level of toxicants shown in the foods analyzed in this study is suggestive of potentials to pose significant health risks to the populace when consumed.

“…The headquarters is located in the town of Ipetumodu in the north of the area at latitudes 07°31.00′-07°51.66′N, and longitudes 004°7.00′-004°45.00′E. It has an area of 889 km 2 and a population of 153,694 at the 2006 census [17]. The study area lies within 7°31.133′N, 004°26.470′E and 07°32.359′N, 004°27.581′E.…”

“…Thus, 36 samples were collected for the 3 months in the dry seasons (December-February) and 36 samples collected for the 3 months in the wet seasons (May-July). Therefore, a total of seventy-two (72) groundwater samples were collected for both wet and dry seasons and the samples were collected in pre-treated bottles [17].…”

“…However, the study did not explore the specie form of the heavy metals which describes their composition, forms of association with the environment for uptake, ionic types, concentration in a given matrix, and consequent health risk to man. Also, a study on the level of polyaromatic hydrocarbons levels in the ground water within the local government have recently been reported [17].…”

This study determined the physicochemical parameters, microbial properties and heavy metal speciation of groundwater in major towns of Ife North Local Government, Area of Osun State, Nigeria, with a view to evaluating the safety of groundwater. Water samples were collected during the dry season (December, 2015 to February, 2016) and wet season (May to July, 2016). A total of 72 samples were collected for the 6 months. Physicochemical parameters were determined in situ while total coliform count was done by membrane filtration techniques. The sequential extraction procedure was used to fractionate the metals (As, Pb, Cd, Cr, Cu, Mn, Ni and Zn) in the water samples. The concentrations of the metals were quantitatively determined using Atomic Absorption Spectrophotometer (AAS, PG 990 Series). The results of the physicochemical parameters of water showed that the pH (6.22-9.93), electrical conductivity (126.02-606.65 µs cm −1), total dissolved solids (78.37-705.31 mg L −1), oxidation reduction potential (303.44-330.17 mV) and temperature (25.83-28.93 °C) were within the limit stipulated for drinking and domestic water. The bacterial flora identified includes Escherichia coli, Yersinra spp, Entrerbacter spp, Citrobacter spp, Seirantia spp, Klebsella spp and Rhebrella spp. The metal speciation revealed free metal ions had the highest concentration with the order free metal ions > suspended particles > bound to organic substances. The study concluded that the groundwaters of the studied area were polluted with microorganisms and the investigated heavy metal, require treatment and monitoring to safeguard human health.

“…Approximately 6-8 mL of the 15-mL total volume of Hex: Ace was separated into the upper layer. The isolation of PAHs was performed using a normal phase mode of solid-phase extraction (SPE) [13]. Activated silica gel was loaded into a glass-chromatographic column, which was followed by the addition of 1 g of Na 2 SO 4 .…”

Distribution and Health Hazards of Polycyclic Aromatic Hydrocarbons in Egyptian Milk and Dairy-Based Products

In a market-basket study conducted in Cairo, Egypt, the most commonly consumed milk products were sampled and the contents of 13 polycyclic aromatic hydrocarbons were analyzed using gas chromatography with a mass spectrometer detector. The obtained data showed that the total amount of 13 PAHs was within the range of 1.3–8.2 µg/g. The results proved that the, highest mean levels of polycyclic aromatic hydrocarbons were detected in powdered milk (8.2 μg/g) followed by ultra-heat treatment milk and milk beverages (6.07 μg/g). The lowest level was detected in unsmoked cheese and yogurt (1.3 μg/g). Estimated daily intake (EDI) was used to estimate the carcinogenic risk. The total mean estimated daily intake for children in different age categories (1–10 years) was calculated with respect to benzo[a]pyrene, which ranged from 0.058 to 0.31 mg/day. The total mean value of EDI for the sum of seven carcinogenic PAHs in terms of benzo[a]pyrene ranged from 0.61 to 1.22 mg/day in all age categories. These results were higher than the critical limit set by the European Food Safety Authority. Therefore, there should be concerns regarding the effects of the consumption of different milk products on the local population.
