Despite the huge nutritional values and availability of local seasonings such as Parkia biglobosa, knorr chicken as food seasonings, some developing countries like Nigeria require more information on the needs for increasing their utilization. Analysis was done using standard analytical methods, to compare the nutritional and heavy metal composition of P. biglobosa seed and bouillon cubes (Knorr chicken, magi star and Tasty cubes). The specific focus was to find out the proximate analysis (carbohydrate, fat, protein and vitamin), heavy metals, Minerals and phytochemicals composition of P. biglobosa and bouillon cubes. Atomic absorption spectrometry was used in the determination of the levels of (Ca, Mg, K, Na, Mn, Fe, Cu and Zn). Phytochemicals, including phytic acid, tannins, carotenoids, phenols, saponins and hydrocyanic acid were also determined using method of Ola and Oboh [19]. The result shows that the seeds of P. biglobosa had significantly higher (p<0.05) Moisture (17.530±3.686) crude protein (25.722±3.524%), crude fat (27.536±2.273%) and Crude fiber (6.540±1.795%) contents compared to the bouillon cubes (Knorr chicken, Maggi Star, tasty cubes). The bouillon cubes had significantly higher (p>0.05) contents of ash (22.188±0.950, 24.092±0.911, 22.880±0.736) which is found to be low in P. biglobosa seed. Carbohydrate level in bouillon cubes were also found to have higher means values of (28.87±1.581, 46.785±2.243, 38.035±12.574). The minerals content of the analyzed samples shows that the P. biglobosa seeds have higher means value in Ca (126.285±16.393), Na (150.820±25.075), and K (1454.432±199.575) and bouillon  cubes were also found to be high in  (Ca, Na , K , Fe), respectively. While the values of (Mn, Zn, Cr  Cb, Pb  pH) were found to have low mean value which were higher than WHO permissible limits. For the ANFs,  P. biglobosa seeds recorded higher levels of  Phytic acid (31.171±8.369 mg/100g), saponins (15.767±4.663 mg/100g) and tannins (55.772±6.655 mg/100g), Total carotenoids (41.561±2.632), Total phenols (65.689±14.439), Hydrocyanic acid (7.618±1.922mg/100g) and Ascorbic acid (101.025±11.670 mg/100g) while it was not detected (ND) in bouillon cubes on analysis. T he heavy metal contents in P. biglobosa was found to be high in copper with mean value of (2.478±2.077) while it was found to be insignificant in (Cr, Cb, and pb)  and are not within the recommended value by WHO. The overall results are suggestive of higher nutritional quality of the Parkia biglobosa seeds than the bouillon cubes. It was therefore recommended that information concerning the use of local seasonings should be made available through public awareness campaign.

Coal fly ash was used to synthesize X-type zeolite by alkali fusion followed by hydrothermal treatment. Characteristics of the various Fly ash samples were carried out. Coal proximate analysis was done. Batch experiment was carried out for the adsorption of some heavy metal ions on to synthesized Zeolite. The cost of synthesized zeolite was estimated to be almost one-fifth of that of commercial 13X zeolite available in the market.

This study developed an effective and economical physical pretreatment of OPEFB to be used as biosorbent for the removal of heavy metal ions such as Cu+2, Zn+2and Pb2+. The effects of fibres sizes, metal ions concentration (100-1000 ppm), initial pH (4-10) and contact time (20-150 min) were investigated in batch system. Samples were characterized with Atomic Absorption Spectrometry (AAS), Transmission Electron Microscopy (TEM) and Fourier Transmission Infra-red Spectroscopy (FTIR). Results showed pH-dependence adsorption efficiency and increased adsorption with initial metal concentrations where more than 92% adsorption efficiency achieved. We have successfully developed an eco-friendly, low cost adsorbent without any chemical modification or excessive energy disposal.

Physical characterization of a soymilk powder was carried out by electron microscopy. Chemical characterization was analyzed by proximate analysis, mineral composition by atomic absorption spectrometry, fatty acid composition by gas chromatography and protein composition by electrophoresis. The powder consists of large granules of 60—80 μm, which may be hollow, with smaller granules of 10—20 μm attached to them. Powder particles are covered by a layer of fat. During storage at 25 °C fat is spreading over the surface, while at —12 °C the fat is contracting. This change affected chemical stability, resulting in high level of fat oxidation when stored at 4 °C or 25 °C as well as a decrease in unsaturated fatty acids. Storage also affected the chemical properties of the re-constituted soymilk; the pH of a 12% soy powder suspension increased from 6.68±0.05 to 7.06±0.08 after 12 months of storage. Storage temperature did not affect the pH of the suspension and this change could also not be ascribed to protein aggregation.

AbstractIn the year 2016, passive biomonitoring studies were conducted in the forest areas of southern and north-eastern Poland: the Karkonosze Mountains (Kark), the Beskidy Mountains (Beskid), Borecka Forest (P. Bor), Knyszynska Forest (P. Kny), and Białowieza Forest (P. Bia). This study used bark from the tree, Betula pendula Roth. Samples were collected in spring (Sp), summer (Su), and autumn (Au). Concentrations of Mn, Fe, Ni, Cu, Zn, Cd, and Pb were determined for the samples using the atomic absorption spectrometry method with flame excitation (F-AAS). Based on the obtained results, the studied areas were ranked according to level of heavy-metal deposition: forests of southern Poland > forests of north-eastern Poland. Some seasonal changes in the concentrations of metals accumulated in bark were also indicated, which is directly related to their changing concentrations in the air during the calendar year, for instance, the winter heating season produces higher concentrations of heavy metals in the bark samples taken in spring. When deciding to do biomonitoring studies using bark, but also other biological materials, it is necessary to take into account the period in which the conducted research is done and the time when the samples are taken for analysis, because this will have a significant impact on the obtained results.
