Abstract: The effect of industrial effluent contaminated sewage water on the content of micro and potentially toxic elements in soils and potato plants was studied. The elemental composition of the sewage water changed due to the contamination from the tannery effluents. The increase in Cr was so dramatic. It increased from 2.7 mg/kg in the control soils to 14 mg/kg in soils irrigated with the contaminated water. The soils of the study area were generally light textured and there was a build up to 30 cm or lower depth. The release of wastewater into the environment polluted not only the irrigated soils but also plants growing in these irrigated soils such as potatoes and onion. Due to disposal of industrial effluents, the waste waters have higher contents of Cu by 42 times, Fe by 155, Mn by 98, Zn by 31, Al by 50, As by 4, Cr by1400 and Ni by 52 times over the tube well water We observed that the concentrations of the contaminating elements were higher in potato and onion the buildup of Cu and Zn was higher in soils than in the vegetables grown in the contaminated soils suggesting a decreased absorption by the plants. Contrary to Cu and Zn, the absorption of Cr and Ni by potato plants and its distribution in inedible non-edible parts was proportional to its build up in soil.

Abstract: This paper deals with the study of sugar in fruits jam of different brands available in the market of Bangladesh. Sugar is a biochemical parameter. The term sugar related to total sugar, reducing sugar and non reducing sugar. Amounts of reducing sugar, non-reducing sugar and total sugar of different fruit's jams available in Bangladesh were determined. The reducing sugar content of different jams ranges from 28.00 % to 60.30 %. The highest amount of reducing sugar (60.30%) was found in Nur mixed Jam and the lowest (28.00%) in Agrokomerc Pineapple Jam. The reducing sugar content of different jams ranges from 28.00 % to 60.30 %. The highest amount of reducing sugar (60.30%) was found in Nur mixed Jam and the lowest (28.00%) in Agrokomerc Pineapple Jam. The total sugar content of different jams ranges from 38.86% to 62.53%. The highest amount of total sugar (62.53%) was found in Nur Apple Jam and the lowest amount of total sugar (38.86%) was found in Agrokomerc Pineapple Jam. Non reducing sugar content of Jams was found in range of 05.33 % to 25.17 %. The highest amount of non reducing sugar (25.17 %) was found in Best Food Orange Marmalade Jam and the lowest (05.33 %) in Nur Apple Jam. The percentage of sugar was determined by using biochemical methods.

Abstract: This study was conducted to assess the extent of trace metals in Modjo tannery wastewater and their levels of contamination in the vicinity of Modjo river water and agricultural soil. Samples of tannery wastewater, river water and agricultural soils have been analyzed for Cd, Cu, Ni, Pb, Zn and Cr using atomic absorption spectrophotometry (AAS). The result showed that the concentration of Zn and Cr metals in Modjo tannery wastewater as well as Cd, Ni and Cr in the river water sample were above the standard values of FEPA and WHO. But Pb was found below the method detection limit for both wastewater and water samples. Results of one - way ANOVA shows that variations for all selected metals in both wastewater and water samples at different sampling points were statistically significant except Cd in the river water sample. For the agricultural soil sample levels of Cd, Ni, Zn and Cr were above NEQS standard limit value. The metal contamination factor (CF) also shows that the agricultural soil was highly contaminated (CF>6) with Cd and Cr, but moderately contaminated (1<CF<3) with Cu, Ni, Pb and Zn. Very high contamination factor for Cr and Cd was observed in the agricultural soil indicating that both tannery wastewater and river water affects the quality of the soil around the tannery factory.

Abstract: A green method was established for the mutual determination of the drug trifluoperazine hydrochloride (TFPH) and vanadium (V) in real samples by coupling the cloud point extraction with UV-Vis spectrophotometry. The method was based on the formation of the colored V (V)-TFPH complex in acidic medium followed the extraction of the complex by using the surfactant Triton X-114 as an extracting medium. The surfactant-rich phase extracted was dissolved in a small volume of solvent and both the drug TFPH and V (V) ions determined by spectrophotometry at maximum absorption wavelength of 476 nm. Most parameters which impact on the extraction efficiency and detection for both target analytes were optimized. Under the optimum conditions established, the preconcentration factor was found to be of 50 fold making Beer’s law obeyed in the concentration range of 2-80 μg mL-1 (r = 0.9999) for the determination of TFPH and 0.5-10 μg mL-1 (r = 0.9995) for vanadium (V), giving the detection limits of 1.21 and 0.113 μg mL-1 respectively. The mean recovery percentage of 98.94±2.19 % (in blood serum) and 99.43±1.40 (in tap water); the precision (RSD %) ranged between 0.48-3.40 % and 0.45-1.49 were obtained for TFPH and V (V) ions respectively. The proposed method was employed for the determination of TFPH in pharmaceuticals and the spiked serum samples, while a V (V) ion was determined in black pepper samples.
