title: Urine level of trace elements in some adults in Bangladesh under a workplace environment.
abstract: The urine level of trace elements has been investigated in some normal adults under different workplace environments in Bangladesh. The samples were collected from 58 subjects, randomly selected from about 500 adults working in 10 different workshops and factories located in Dhaka city. Samples were analyzed by the external beam PIXE method. Proton beams of 2.5 MeV energy and 20 nA intensity were used for sample irradiations. For 40 microC irradiations, the concentration of 14 elements in total (K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Rb, Sr and Mo) in different groups were measured by comparison with a calibration curve obtained from the NBS Orchard Leaf standard (SRM 1571). The results from different workplaces are reported in terms of amount of excretion per unit volume of the sample collected. They, however, do not reflect the total daily excretion level of different subject groups.
