| Field Measurement of Air Pollutants near Swine Confined-Animal Feeding Operations Using UV DOAS and FTIR |
| Secrest, Cary D., U.S. EPA. Water, Ground, and Air Pollution Monitoring and Remediation, 6-7 November 2000. Proceedings of SPIE--The International Society for Optical Engineering, Vol 4199, p 98-104, 2001 |
This paper reports the results of ammonia measurements near two confined-animal feeding operations (CAFOs) in September 1999 and March 2000. Measurements at the first site were conducted for 48 hours downwind using two open-path monitors: an ultra-violet differential optical absorption spectrometer (UV-DOAS), and a Fourier transform interferometer (FTIR). Measurements at the second CAFO were taken using only UV-DOAS. This paper describes the calibration of a UV-DOAS, compares UV-DOAS and FTIR measurements, describes the effects of wind and atmospheric stability on ambient ammonia concentration, and suggests potential applications for open-path monitors for assessing risks to public health. |
