Description
Summary:Total particulate matter (PM) emission factors for steel grit used in dry abrasive blasting were examined. Regression equations expressing total PM emissions as function of blast pressure and abrasive feed rate were developed to estimate uncontrolled total PM emissions. The results were helpful in controlling emissions, developing emission inventories, developing best management practices, and selecting process parameters corresponding to minimum emissions for steel shot and grit. The equations presented would help industries in optimizing the process conditions and selecting blast pressure and feed rate settings corresponding to lowest total PM emissions. High correlation coefficient obtained indicated the closeness of the filled data with the predicted values. The results concluded that the emission equations would also be useful in computing the public health risks when particle size and metal speciation becomes available.
