The article reports on the first national study of air pollutants from dairy cow, swine and poultry farms launched by the U.S. Environmental Protection Agency. Researchers will measure emissions of hydrogen sulfide, ammonia and other gases from livestock farms in nine states across the country. The agency will then create a model to enable individual operations to check whether they need a permit. However, some environmentalists opposes the study because for them it is not comprehensive and may underestimate emissions.
