ABSTRACT:
Cylindrical method of quantifying fugitive emission rates from pollution sources, such as those emanating from ore mines, factories, office buildings, and the like.
The method is characterized by its ability to quantify airborne fugitive emissions by defining an arcuate profile of pollutant flux, while driving a pollutant sensor in a peripheral arc surrounding the pollution source. According to wind changes, the pollutant sensor may be advanced peripherally of the pollution source to an arcuate detection plane downwind, so as to quantify fugitive emission rates, regardless of source emission characteristics or wind direction.
