This study evaluates the essential trace element contents of some locally grown varieties of rice in Nigeria. Eighteen local variety from 14 rice producing states in Nigeria were obtained from popular markets. Samples were dried, homogenized and later digested using proportionate amount of HNO3/H,O2. The concentrations of the three elements (Cu, Mn, Fe) were determined using Atomic Absorption Spectrophotometer. The method used was validated using a certified reference. The result showed the following ranges of concentrations: Cu (1.00 ± 0.02-5.00 + 0.14), Fe (10.85 ± 0.50-38.40 ± 0.99), and Mn (1.95 ± 0.65-32. 10 + 0.24) mg/kg. The concentration of Cu, Fe and Mn in the studied local rice suggest their nutritional potentials as food for sourcing essential trace elements. The values of the essential trace elements were below the WHO permissible limit which indicates consumption safety. The rice from ldanre and Lafiagi have substantial content of Cu. Ofada and Ikirun rice are rich in Fe content. Substantial amount of Mn was found in Abakaliki and Efon-Alaaye rice. The studied local rice could play a beneficial role in management of mineral deficiency diseases. 2021-01-01T00:00:00Z http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/27811 Title: Physiochemical Properties and Heavy Metals Analysis of Effluent Water from Selected Tannery Sites in Kano and Zaria. Authors: Anyanwu, S.K; Andrew, A; Idika, P; Ndatmso, M.M Abstract: The study was aimed to determine the physiochemical properties and heavy metal of effluent water sourced from tannery sites within Kano and Zaria metropolis. Effluent samples were taken from four different tannery sites: Kano and Zaria. Each sample was collected in plastic containers that were carefully rinsed with deionized water after being previously cleaned with detergents and 10% HNO3 acid. All of the samples were brought to the laboratory for analysis using standard methodology. The Results revealed pH (3.55-9.35), Electrical Conductivity(EC)(21410-224µs/cm), Total Suspended Solids(TSS) (2150-3546.60 mg/L) and Total Dissolved Solids(TDS) (1468-8260 mg/L) across the sites. Parameters such as EC, TSS and TDS were not in conformity with the WHO Standard except pH (9.35±3.55) for site1 from Kano metropolis. Heavy metal such as Cr (3.52-4.93 mg/L), Pb (1.35-2.7 mg/L), and Cu (1.24-1.82 mg/L) were not in tandem with WHO standard across the sampling sites except for Fe (4.64-8.32 mg/L) that conformed. The studied effluent water showed significant deviation from WHO standard and as such monitoring to treat/determine the safety level should be promoted.

This study is aimed at evaluating the phytochemical, proximate and anti-nutritive components of senna obtusifolia leaves and seeds. Normal standards were used to attain the proximate and anti-nutritive components of the leaves and seeds respectively. The proximate composition in percentage of senna obtusifolia seeds are: moisture content 20.16, ash 23.75, crude fat 3.90, crude protein 28.00 and carbohydrate 24.19. high proximate composition was recorded in crude protein, carbohydrate and ash content. While for the leaves, moisture content 24.86, ash 19.34, crude fat 5.11, crude protein 38.5 and carbohydrate 12.19. high proximate composition was seen in crude protein, moisture content and ash. Some of the values were within the expected range according to FAO 2019. The anti-nutrient composition in Senna obtusifolia leaves and seeds reads 205.95 and 271.62 in phytate, 163.00 and 145.00 in Oxalate, 0.07 and 0.03 in cyanide, 849.54 and 655.09 in Saponins and same value of 928.57 in both leaves and seeds for Tannins respectively. Some of the values shown here too are in accordance with the FAO 2019. Hence the result if the analysis shows that both the leaves and seeds of senna obtusifolia could serve as a good laxative, medicinal and therapeutic values for man if further processes are done to remove the inherent toxicants in the leaves and seeds.

This study evaluate the quality of engine oil sold by some road-side vendors in Minna metropolis. Eight oil samples were randomly collected and analyzed for physicochemical parameters which include speciöc gravity, pour point, øash point, cloud point, kinematic viscosity, acid value, iodine value and saponiöcation value using standard methods. The results of the parameters analyzed were speciöc gravity (A1 (0.897), A2 (0.883), B1 (0.891), B2 (0.890), C1 (0.894), C2 (0.908), D1 (0.899) and D2 (0.896) ), pour point (A1 (-6.2 oC), A2 (-6.5 oC), B1 (-5.9 oC), B2 (-4.5 oC), C1 (-4.7 oC), C2 (-3.6 oC), D1 (-6.5 oC) and D2 (-6.9 oC) ), øash point (A1 (256.8 oC), A2 (239.4 oC), B1 (269.2 oC), B2 (165.5 oC), C1 (175.9 oC), C2 (144.2 oC), D1 (161.8 oC) and D2 (191.2 oC) ), cloud point (A1 (-9.9 oC), A2 ( -9.0 oC), B1 (-4.6 0C), B2 (-1.8 oC), C1 (-7.4 oC), C2 (-9.8 0C), D1 (-6.7 0C) and D2 (-4.8 oC), kinematic viscosity (A1 (43 mm2 /s), A2 (36 mm2 /s), B1 (35 mm2 /s), B2 (43 mm2 /s), C1 (34 mm2 /s), C2 (32 mm2 /s), D1 (42 mm2 /s) and D2 (41 mm2 /s) ), acid value (A1 (1.42 mgKOH/g), A2 (1.68 mgKOH/g), B1 (1.34 mgKOH/g), B2 (1.58 mgKOH/g), C1 (1.90 mgKOH/g), C2 (1.34 mgKOH/g), D1 (1.34 mgKOH/g) and D2 (1.34 mgKOH/g) ) , iodine value (A1 (13.1 mgI2 /g), A2 (9.7 mgI2 /g), B1 (10.2 mgI2 /g), B2 (13.3 mgI2 /g), C1 (13.11 mgI2 /g), C2 (10.8 mgI2 /g), D1 (20.1 mgI2 /g) and D2 (13.8 mgI2 /g) ) and saponiöcation value ( A1 (196.35 mgKOH/g), A2 (143.05 mgKOH/g), B1 (167.18 mgKOH/g), B2 (192.42 mgKOH/g), C1(173.23 mgKOH/g), C2 (143.00 mgKOH/g), D1 (147.54 mgKOH/g) and D2 (106.31 mgKOH/g). This study revealed that the two most important parameters of engine oil, kinematic viscosity and acid value were below and above the stipulated standards by the ASTM (48 mm2 /s and 0.02-0.8 mgKOH/g). These deviations from the standard values stipulated by ASTM might be due to adulteration of the engine oils. Therefore, Government agencies with mandate of monitoring engine oil quality should carry out periodic evaluation of the engine oils sold by the roadside vendors to check their sharp practices.
