The key objective of this work is to measure total concentration of metals like Zn, Cu, Fe, and Mn in the industrial dust particles settled outside the processing site of brass foundries by using different analytical techniques; such as DTPA extraction, acid digestion methods and analysis of metals using Atomic Absorption Spectrophotometer.Industrial dust particles from brass foundries contains large amount of Zinc and Copper. This contains too the considerable amount of Iron and Manganese. Analyzing these dust particles help us to understand the need of managing them in proper way, which...
