What are the most significant air pollutants (e.g., dusts, volatile organic compounds and ammonia), their sources (including housing, storage ponds, lagoons, litter piles, and land application fields) and their emission rates from AFO operations? What metrics, methods, and models should we use in the future to quantify and monitor these emissions to better understand their relationship to atmospheric deposition and the formation of ground-level ozone and PM2.5? | |

| Session 3 - Pharmaceuticals and Pathogens | |
| 4. What specific analytic methods (and associated sampling, preservation and preparation techniques) should be used in an environmental setting for the veterinary pharmaceuticals and microorganisms most likely to be found in the environment and most likely to be linked to adverse human health effects, e.g., drugs such as tetracyclines, sulfonamides, and trenbolone; and pathogens such as Cryptosporidium parvum, Campylobacter spp., and E. coli O157:H7? | |
