Abstract: This research investigates the concentrations of some trace metals present in waste ashes collected from five different sections of a major incineration ground at Maikunkele, Minna, Niger State, Nigeria. Waste ash samples from the sites were collected and prepared using standard analytical procedures and analytical grade reagents were used for digestion. An atomic absorption spectrophotometer (AAS) was used for the analysis of the trace metal (Zn, Cu, Pb, Cd and Ni) content of the samples. The mean concentrations of trace metal in the ash samples differed significantly amongst sites which ranged from 34.1-104.4µg/g (Pb), 2.9-7.9µg/g (Cd), 94.6-206.7µg/g (Cu), 49.7-87.0µg/g (Ni) and 590.1-2622.0µg/g (Zn). These mean concentrations were found to exceed critical level for agricultural use at site 1 (Cd and Zn), site 2 (Cd and Zn), site 3 (Ni and Zn), site 4 (Cd, Cu, Ni and Zn) and site 5 (Cd, Cu, Ni and Zn). Further research is thus required to determine the plant-availability of these metals in the ash and to assess the wider environmental and health implications of open burning of waste as a means of producing ash for agricultural purposes.

Abstract: This paper deals with the study of protein in Jams, Jellies and Juices of different brands available in the market of Bangladesh. Fruits and fruits products are occupying a larger proportion of daily food item of modern civilized nation certainly due to their great food values. Jams, Jellies and Juices also have good food values as these are made from fruit water and sugar. The present study shows that the investigated result of Protein was found in a range of 0.04%-0.79% in jams. The highest protein content (0.79%) was found in Best food orange marmalade Jam and the lowest (0.04%) was found in Nur Apple Jam. Most of the Jellies contain small amount of protein. Protein was found in a range of 0.02% -0.06% in the present investigated Jellies. Protein is absent in Pran Apple Jelly. Protein content of juices was found in a range of 0.0% to 0.03%. The highest protein content (0.03%) was found in Pran Premium mango Juice and the lowest (0.01%) was found in Acme Premium mango Juice and Starship (Mango) Juice. Protein is absent in other four brands. Most of the people like fruits very much but in some cases a few of them don't like that of unknown cause. In that case Jam, Jelly and Juice are only the alternative source of protein in lieu of fruits. In this paper percentage of protein was determined by using biochemical methods.
