Assessment of in-plant particulate matter and its toxic metals contents of sponge iron industry in Goa, India.
The present study attempted to assess toxic metal contents (Arsenic, Cadmium, Copper, Cobalt, Chromium, Iron, Manganese, Nickel, Lead and Zinc) in Total Suspended Particulate (TSP) and Particulate Matter less than ten micron (PM₁₀) in three sponge iron industries in Goa (India), one of the famous tourist place on the World map. TSP and PM(10) average concentration in all three sponge iron industries were found to be in the range 401-485 μg/m³ and 135-270 μg/m³ respectively. Amongst all the metals, concentration of iron was the highest in TSP as well as in PM₁₀. Statistical results indicate that proportion of specific metals were found higher in PM₁₀ as compared to the ratio of PM₁₀/TSP ratio. Value of correlation coefficient was found to be significant for Cr-Pb indicating coal burning was the major source contributor.
