CAFO Odor Studies
The below links were compiled by Kathy Martin, PE. CAFO proponents are fond of saying "there's no study showing any impact from CAFOs". This is patently and blatantly untrue - repetition of a lie doesn't make it true. The next time this is stated, throw a few of these studies in the speaker's face.

1. Thermal imaging of exhaust from hog barns (http://www.iihr.uiowa.edu/projects/pigbarn)
2. Animal health effects from chemicals in barns (http://www.public-health.uiowa.edu/ehsrc/CAFOstudy/CAFO_6-2.pdf)
3. Difference between treated and untreated swine waste..........ammonia, nitrates, pathogens. good graphics. (http://ari.calstate.edu/research/pdf/01-5-031/FinalReport-01-5-031.pdf)
4. A pretty technical article on how olfactory receptors interact with chemicals and the relationship between binding sites and odor recognition. this is a good one to slap on the folks that say there is no science in odor research. there is. it is just not in the land grant universities. (http://chemse.oxfordjournals.org/cgi/reprint/29/4/269)
5. Good article relating feed composition to malodorous compounds. it experiments with chicory. but i think the basic info in the article is a good foundation to understanding that odor can be manipulated by feed (http://jas.fass.org/cgi/reprint/82/6/1678)
6. Research from Austria. good graphics showing odor intensity differences in time of day and season/wind (http://www.geruch.at/Publikationen/2005/OD_Episodes_ISB05.pdf)
7. 2005 reprint of 2003 Susan Schiffman odor study on human health -- headaches, etc. (http://www.ehponline.org/members/2005/6814/6814.pdf)
8. Schiffman study on odor versus waste treatment technologies (http://www.cals.ncsu.edu/waste_mgt/05wastesymposium/PDFS/Schiffman.pdf)
9. An oldy but goody --- late 1990's study by region vi on cafo odors. has it really been more than a decade? (http://www.epa.gov/earth1r6/6en/xp/odor.pdf)
10. A USGS report on characterization of organic matter in swine lagoons. (http://pubs.usgs.gov/sir/2004/5217/pdf/sir2004-5217.pdf)
11. Short report on odor study using GC.........p-cresols and other volatile organic compounds. actually a bit alarming. (http://www.p2pays.org/ref/32/31218/VOC.pdf)
12. 1998 Schiffman report on odors and health effects (http://jas.fass.org/cgi/reprint/76/5/1343)
13. I really like this one........relates odor to the feed (http://mark.asci.ncsu.edu/SwineReports/2003/vankempen2.htm)
14. 2004 Schiffman and Williams article on odor and health (http://jeq.scijournals.org/cgi/content/full/34/1/129#TBL1)
15. Heber article on measuring odor from hog barns (http://pasture.ecn.purdue.edu/~odor/cd/September05/journal%20articles/heber%202001%20emission%20measurement%20methods%20-%20trans%20asae.pdf)
16. This document talks about the combination of urine and feces is what causes the odor compounds to develop. if kept separately........not the same chemical and biological reactions. this article looks at lowering the pH of urine in order to prolong the generation of odor causing chemicals.....as is dictated by the buffering capacity of the feces. good stuff. (http://jas.fass.org/cgi/reprint/79/9/2412.pdf)
17. This study shows hydrogen sulfide increases over time as microbial community thrives. deep pit (http://www.ddgs.umn.edu/articles-swine/1999-Nicolai-%20Deep%20pit%20simulator--.pdf)
18. This series of abstracts presented at north carolina air workshop. (http://www.ncsu.edu/airworkshop/Agricultural_Emissions.pdf)

Health impacts from CAFOs - Germs in Manure.
Compiled by Kathy Martin, PE. These may be used to counter those idjits who claim "There's no study that documents health impacts". There are, in fact, many such studies - below is a sampling.

1. Amy Chapin of Johns Hopkins - Airborne multi-drug resistant bacteria from cafos (http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1277855)
2. Pathogens in tomatoes - lab study (http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=126780)
3. E. coli in drained and undrained fields after manure application - european study (http://jeq.scijournals.org/cgi/reprint/34/3/918.pdf)
4. California report.......around page 4 or so they start talking about e coli contamination of leafy vegetables due to untreated manure....... (http://www.rcdmonterey.org/pdf/Food_Safety_Environmental_Protection_2006.pdf)
5. I think this is similar to #3........stormwater runoff of bacteria from grazing fields with manure application. (http://www.ucd.ie/dipcon/docs/theme03/theme03_07.PDF)

17. This is where i learned a new word "internalization" in this case E. coli in bean sprouts. it sounds so nice but it really isn't. (http://www.blackwell-synergy.com/doi/pdf/10.1046/j.1365-2672.2003.02037.x?cookieSet=1)
18. Just the abstract (I didn't buy the article) but it talks about using ZnO as an indicator of e coli transport through soils because of similar size. again, if the pigboys say there is no research they are totally full of shit. there is just gobs of stuff in the literature. (http://www.blackwell-synergy.com/doi/abs/10.1111/j.1475-2743.2000.tb00177.x?prevSearch=keywordsfield%3A%28%22Escherichia+coli%22%29++or+keywordsfield%3A%28%22internalization%22%29)
