Abstract

Heavy metals are shown to be a major indoor dusts pollutant. The health risk assessment of Heavy metal contents of dusts collected from classroom corners of some randomly selected public primary schools in Rivers state was carried out. Dust samples from Classroom corners of three (3) Public primary Schools in Obio/Akpor, Eleme, and Ikwerre Local Government Areas (LGAs) was collected and analyzed for Lead (Pb), Cadmium (Cd), Chromium (Cr), and Arsernic (As) using Atomic Absorption Spectrophotometer (AAS, GF, Flame HVG). The heavy metal concentrations obtained from the analysis revealed that mean maximum level for Pb and Cd were obtained from E at 25.39±0.09 and 3.52±0.23 mg kg-1 respectively, while that of Cr and As were obtained from H at 45.24±0.02 and 1.53±0.06 mg kg-1. The minimum levels were observed at E. The Average daily intake Dose (ADDingestion, dermal and inhalation) and corresponding Target Hazard Quotients obtained revealed oral ingestion as major exposure pathway, though with no evidence for non carcinogenic risk/Hazard index (HI), but with children population being more exposed to Life cancer Risks (TLCR) except at F. It is however recommended that same risk assessment be made on agricultural products harvested from Primary School Farms and Borehole water within these regions.

Abstract

The nutraceutical potential of Tetracarpidium conophorum and Buccholzia coriacea in diet-induced hyperlipidemia in male Wistar rats were investigated at the Plant Science and Biotechnology department, University of Port Harcourt, Nigeria in 2016. Diet-induced type II A hyperlipidemia in rat model was achieved by oral administration of egg yolk and groundnut oil formulations for 2 wk. Rats fed with normal diet and diet formulations constituted the negative control and test control in that order for comparison. The hyperlipidemic rats were subsequently treated with normal feed supplemented with 500 mgkg-1 and 1000 mgkg-1 of T. conophorum and B. coriacea for two weeks. In comparison to test control animals, administration of tried samples markedly lowered weight gain by experimental animals, total cholesterol, triglycerides, AST, ALT ALP, plasma contents of LDL, VLDL, Non-HDL and atherogenic indices in a dose- dependent fashion. Their administration also produced significantly higher (P<0.05) plasma HDL cholesterol levels indicating recovery. These findings underscore the nutraceutical potentials of T. conophorum and B. coriaceaand suggest their possible use in management of hyperlipidemia and other related diseases.
