Abstract :

The Particle Induced X-ray Emission (PIXE) Technique under Powerful Ion beam Analytical (IBA) Technique has been turned to account for the determination of the concentrations of soil elements of different manufacturing garment areas at Savar, Dhaka. The study area was classified into three sub-regions of Savar, Dhaka consisting of (1) Fountain Manufacturing Garment area, (2) Vadail Bazar, and (3) Gonokbari area. The neoteric machineries available in the accelerator Laboratory of Atomic Energy Centre, Dhaka (AECD) have been used for the research works, from sample preparation to data analysis. The proton beam energy 2.2 MeV and the current range 10-15 nA are used in this research. Microbalance, pellet maker etc. have been used for sample preparation. A [Si (Li)] detector associated with other equipments such as amplifier, PC and Smartphones are used for data procurement. The energy of the emitted X-rays indicates the identity of the soil elements and the intensity of the X-rays gives the measurements of the concentrations of the elements existed in the samples. DAN-32 software was used to analyze the collected spectrum data. The detected elements in soil samples and their concentration are Aluminium (3322 to 7299 µg/g), Si (177 to 521 µg/g), Chlorine (87 to 423 µg/g), Potassium (5009 to 7617 µg/g), Calcium (2366 to 5390 µg/g), Scandium (71 to 134 µg/g), Titanium (145 to 3148 µg/g), Vanadium (45 to 135 µg/g), Chromium (48 to 96 µg/g), Manganese (237 to 508 µg/g), Iron (8620 to 14655 µg/g), Nickel (07 to 556 µg/g), Copper (8 to 40 µg/g), Zinc (22 to 90 µg/g), Germanium (7 to 10 µg/g), Selenium (2 to 8 µg/g), Rubidium (84 to 856 µg/g), Strontium (92 to 139 µg/g), Yttrium (5 to 43 µg/g) and Zirconium (287 to 407 µg/g). It is shown that the concentration of Iron is about 34.83% of the total extent comparing to all elements present in the soil samples. This is a horrific signal both for soil and environment. Moreover the presence of Chromium and Titanium, though their concentrations are low, are very detrimental for crops.
