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.

Abstract: Device for sampling air in proportion to respiration, particularly the collection of air pollutants in proportion to the actual respiration of the wearer. The device includes a pump supported adjacent the thoracic cavity and activated by the expansion and contraction of the thoracic cavity during respiration, so as to draw air through an air sampling monitor.
