Air Quality Concerns
Toxic gases, vapors, and particles are emitted from CAFOs (Concentrated Animal Feeding Operation) into the general environment. These include ammonia, hydrogen sulfide, carbon dioxide, noxious vapors, and particles contaminated with a wide range of microorganisms. Not only do the facilities themselves pollute the air, the smell of the liquid manure (when it's spread on the fields) can travel for miles, depending on wind speed and air temperature and humidity.
- Extensive occupational health studies since 1977 have documented acute and chronic respiratory diseases among CAFO workers, especially swine and poultry workers. CAFO workers commonly complain of sinusitis, acute and chronic bronchitis,inflamed mucus membranes and irritation of the nose and throat, headaches, muscle aches and pains.CAFO workers also experience asthma and acute and progressive decline in lung function. (Cole D, Todd L, Wing S, Concentrated swine feeding operations and public health: a review of occupational and community health effects, Environ Health Perspect 108:685-699 (2000))
- Particulate matter associated with CAFOs is composed of fecal matter, feed materials, skin cells, and the products of microbial action on feces and feed. (http://www.public-health.uiowa.edu/ehsrc/CAFOstudy/CAFO_finalChap_3.pdf)
- Bioaerosols are a major component of the particulate matter from CAFOs. Bioaerosols are simply particles of biological origin that are suspended in air. These include bacteria, fungi, fungal and bacterial spores, viruses, mammalian cell debris, products of microorganisms, pollens, and aeroallergens (Table 3-1). Bacterial and fungal bioaerosols may be of infectious or non-infectious species. Bacterial products or components exist as bioaerosols and include endotoxins, exotoxins, peptidoglycans, lipoteichoic acids, and bacterial DNA bearing CpG motifs. (http://www.public-health.uiowa.edu/ehsrc/CAFOstudy/CAFO_finalChap_3.pdf)
- Health effects associated with inhalation of toxins and bioaerosols are manifold. Medical problems commonly associated with inhaled agents include respiratory diseases (asthma, hypersensitivity pneumonitis, industrial bronchitis), cardiovascular events (sudden death associated with particulate air pollution), and neuropsychiatric conditions (due to odor as well as delayed effects of toxic inhalations). (http://www.public-health.uiowa.edu/ehsrc/CAFOstudy/CAFO_6-3.pdf)
- The anaerobic reaction that occurs when manure is stored in pits or lagoons for long amounts of time is the primary cause of the smells. Odors from waste are carried away from farm areas on dust and other air particles. (http://www.cdc.gov/nceh/ehs/docs/understanding_cafos_nalboh.pdf)
- A group of eight organizations, including the Humane Society of the United States, Center for Food Safety and the Sierra Club, filed two lawsuits in January 2015 against the EPA for not doing enough to control emissions from CAFOs. One lawsuit deals with ammonia pollution, and the other addresses methane and other air pollutants. (http://thinkprogress.org/climate/2015/01/30/3617172/epa-cafos-lawsuit/)

Nearly 1100 Hogs Killed by Hydrogen Sulfide Gas in Tracy, Taken to Nearby Landfill to be Buried

As you can see if the fans stop the pigs die. These gases are vented outside the barns and into the neighborhood every day?? What about the down wind people being constantly exposed to varying levels of these poisons? (See wind rose at top of page.)

A slideshow by Bob Watson and Larry Stone
The slideshow below (click the arrows to view) was used in a presentation Bob Watson, from Decorah Iowa, gave at the Washburn Library on September 23, 2015. Bob described what Iowa is like for those people who live or go to school near CAFOs. He explained what happens to the environment and to human health as a result of confinement waste and gases—a glimpse of what our future will be like if the Badgerwood CAFO goes forward.
Bob has put together a "460 study packet for boards of health". The packet, which includes the Jillian Fry Johns Hopkins study (a seminal paper on air quality issues), shows the gap between "known public health threats" from industrial ag, and what officialdom is doing to protect the public from those threats.
The packet contains 177 of the 192 studies on hydrogen-sulfide and ammonia that were included in Bob's 2012 EPA lawsuit. These studies were not disputed by the Washington DC Federal District Court. The lawsuit asks that the EPA put hydrogen-sulfide and ammonia on the regulated list (they are currently only on the toxic list), and asks that confinements be designated stationary sources of those gases.
Bob's additional confinement information and studies can be seen at www.civandinc.net appendix E.
