PM10 based Emissions from Abrasive Blasting of Mild Steel by Steel Grit or Steel Shot

Use this spreadsheet when the emissions are from an Abrasive Blasting of Mild Steel# by Steel Grit or Steel Shot and the PM10 rates are known Entries required in yellow areas, output

in grey.

PM10 Rate Emissions are calculated by the multiplication of the PM10 Rates and Weight Fractions.

Emission Factor Sand PM10

Weight Fraction #

Mild Steel Baseline %

Enter the % of the metal in the steel as a number and not as a decimal equivalent. Do not enter a value for Hexavalent Chromium. The new emission factor will include addition of the original weight fraction where appropriate.

*The emission factors are from Table 5 (pg. 24) of the December 2005 study, Residual Risk from Abrasive Blasting Emissions:Particle Size and Metal Speciation conducted by Advanced Technology Institute. http://www.nsrp.org/Project_Information/panel_projects/deliverables/environmental/airborne_particle_size_metals.pdf Study used mild steel painted panels and speciated PM10 for metals

There is indication in the Abrasive Blasting studies that were reviewed that the concentration of metals in the PM10 is greater than the concentration in the constituents (abrasive material and abraded surface)

# For other metals use the approximation of (7.28 e-06 * (% of new metal -% of mild steel) + Abrasive) Based on Manganese uptake as PM10 during Sand Blasting of mild steel. Enter the values for the emission factor calculator. This is an approximation and does not replace more robust methods, such as a source test. If % is less than baseline it will default to the Abrasive emission factor or if the metal is not present the mild steel sand abrasive emission factor.
