Assessment of Polycyclic Aromatic Hydrocarbons (PAHs) in Smoked Fish (Hydrocynus Forskahlii) from Tombia Community-Ekpetiama, Bayelsa State

Authors : Orodu V. E. ; Peri Samuel Sunny
The assessment of Polycyclic Aromatic Hydrocarbons (PAHs) was done in smoked fish (Hydrocynus forskahlii) gotten from Tombia Community-Ekpetiama, Bayelsa State. The smoked fish sample was oven dried and ground thereafter. 1g of the ground fish sample was weighed and digested using n-hexane. The solution was then filtered and the filtrate ran in Gas Chromatograph-flame ionization detector (GC-FID). The following results were obtained, naphthalene 20.36µg/kg, 2-methylnaphthalene 1.91µg/kg, acenaphthylene 1.90µg/kg, acenaphthene 0.34µg/kg, fluorene 0.33µg/kg, flouranthene 7.05µg/kg, pyrene 3.50µg/kg, chrysene 0.07µg/kg, benz (a)anthracene 0.09µg/kg, benzo(b)fluoranthene 2.56µg/kg, benzo(k) fluoranthrene 6.66µg/kg, benzo(a)pyrene 0.087µg/kg, indeno(1,2,3–cd)pyrene 0.27µg/kg, dibenz(a,h)anthracene 0.76µg/kg while two PAHs phenanthrene and anthracene were not detected. The total concentration of the PAH was 45.89µg/kg. The ratios of ([Fla/ (Fla + Py]) is 0.66µg/kg and ([FLa/Py] is 2.02µg/kg]) which indicate the PAHs detected is from the smoking process. The maximum permissible level of the sum of PAH4 (Chrysene, Benz(a)anthracene, Benzo(b) fluoranthene, Benzo(a)pyrene) in smoked fishery products is 0.03 mg/kg (European Union., 2014) and the sum of PAH4 in this research work is 0.0002822mg/kg which is below the Europian Union (EU) recommended standard. The concentration of benzo(a)pyrene is below the E.U recommended limit of 5µg/kg indicating that the fish is healthy for consumption and may not pose cancer and other health risk.

Ethnomedicinal Survey of Plants Used as Remedy for Alzheimer’s Disease in Ebonyi State, Nigeria

Authors : Nduche M. U.
In the inventory, an ethnobotanical survey was carried out to document the plant families, species and parts of plants used in the management of Alzheimer’s disease. The result revealed that a total of 45 plant species from 29 families mostly of the Fabaceae (17.24%), Graminae (13.79%), Amaryllidaceae (10.35%) and Laminaceae (10.35%). The commonest plant species identified include; Zingiber officinale Roscoe (ginger), Allium cepa L. (onion), Allium sativum L. (garlic), Telfaria occidentalis Hook F (fluted pumpkin), Manihot esculenta Crantz, (cassava), Zea mays L. (maize), Cymbopogon citratus (DC ex Nees) Stapf (lemon grass), Curcuma longa L.(turmeric) and Vitis vinifera L. (grape). All the plants identified in this inventory have been used by the herbal practitioners and adjudged to be effective. Despite the survey, more research is needed in the extraction and isolation of active chemical constituents in these plants for the formulation of drugs and other pharmaceutical purposes.
