Emission Factor - Valley Air

An emission factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant.

11.24 Metallic Minerals Processing - US EPA

Emission factors are provided in Tables 11.24-1 and 11.24-2 for two types of dry grinding operations: those that involve air conveying and/or air classification of material and those that involve screening of material without air conveying.

Profiling Mild Steel Welding Processes to Reduce Fume Emissions

Results indicate a wide range of fume emission factors for the process variations studied. Fume emission rates per gram of electrode consumed were highest for SMAW (~13mg fume g −1 electrode) and lowest for GMAW processes such as pulsed spray (~1.5mg g −1 ) and CMT (~1mg g −1 ).
