Trace element emissions from some cement plants in Turkey

Air pollution regulation of Turkey deals with the problem of trace element pollution by categorizing inorganic material in two groups and three different classes each and by issuing different emission limits for each class. In the present study, dust samples obtained from main stacks of three cement plants located in three different geographical areas are analyzed for their trace elements including Be, Cd, Cr, Pb, Ni, Se, Te, Tl, V, Sb, Ba, Zn, Co, Sr, Cu, Bi, Ca, Mg and Mo. Sequential plasma type AtomScan 25 inductively coupled plasma spectrophotometer of Thermo Jarrell Ash Corporation has been used in the final analysis of the elements. The samples have been prepared by the modified TJA Portland cement analytical method.
