1. Cylindrical method of quantifying fugitive emission rates from pollution sources comprising:
- A. driving a pollutant sensor in a peripheral arc surrounding a pollution source;
B. gauging wind velocity and direction at an index point downwind of the pollution source;
C. advancing said pollutant sensor to said index point;
D. outlining at said index point an arcuate pollution detection plane, said plane being oriented transversely and vertically with respect to the wind;
E. sensing pollutant concentration at a series of height intervals within the vertical and lateral confines of said arcuate pollution detection plane, so as to obtain integrated products of cross wind concentration and wind speed; and
F. displaying said products as a vertical profile of total mass flux of pollutant through said detection plane.

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.
