Kuska reply: Please provide the references Henry Kuska, retired http://home.neo.rr.com/kuska/ Sure, no problem. Try: Williams GM, Kroes R, Munro IC. "Safety evaluation and risk assessment of the herbicide Roundup and its active ingredient, glyphosate, for humans." Regul Toxicol Pharmacol 2000 31:117-165. The danger of Roundup is so small that it is difficult to provide any study that will show any excess mortality. Attempts to do so have failed. However, it is possible to calculate the excess mortality of all pesticides/herbicides put together (of which Roundup is among the most safe). Thus, lumping Roundup in with known carcinogens and bad actors, you can get some data about the real environmental risk in terms of excess cancer mortality. On average, there are 20 excess deaths per year in the US due environmental exposure to all pesticides and herbicides combined, out of a total of around 560,000 total cancer deaths in 1999. In 1981, Doll and Peto's epidemiologic estimates of quatitative cancer risk found pesticide/herbicide exposure to be negligible (Doll R. Peto R. "The causes of cancer: quantitative estimates of avoidable risks of cancer in the United States today" J. Natl. Cancer Institute. 1981 1191-1308.). This study was confirmed in 1987 by the EPA (Gough, M. "Estimating cancer mortality: epidemiological and toxicological methods produce similar assessments." Environ Science and Technology 23:925-930). This was again confirmed in 1996 by the National Research Council of the National Academy of Sciences who found that "the great majority of individual naturaly-occuring and synthetic chemicals in the diet appear to be present at levels below which any significant adverse biologic effect is likely, and so low that they are unlikely to pose an appreciable cancer risk." (NRC, 1996 "Carcinogens and anticarcinogens in the human diet: A comparison of naturally occurring and synthetic substances. National Research Council. Washington, DC. National Academy Press. http://books.nap.edu/books/0309053919/html/index.html http://stills.nap.edu/html/diet/summary.html This was again confirmed in 1996 a consortium including the World Cancer Research Fund, American Institute of Cancer Research, World Health Organization, National Cancer Institute, and the International Agency for Research on Cancer. Their metanalysis revealed that food contamination with pesticides posed any significant cancer risk. In fact, they note that the use of pesticides may *reduce* the rate of cancer worldwide by making foods with cancer-preventative substances more available. In particular they note that "there is no direct evidence that herbicide residues, when regulated and monitored, significantly affect human cancer risk." (Chapter 7, Section 7.1.2 "Herbicides.") World Cancer Research Fund. "Food, Nutrition, and the Prevention of Cancer: A Global Perspective." New York: American Institute for Cancer Research. ISBN 1899533052 670 pp http://www.wcrf.org/report/ This was again confirmed in 1997 with the Canadian Cancer Society report on pesticides, which affirmed Doll and Peto's conclusion. "The Panel concluded that it was not aware of any definitive evidence to suggest that synthetic pesticides contribute significantly to overall cancer mortality." "8. The Panel did not find any exising evidence that crop protection chemicals and lawn and garden products are likely to be a major cause of cancer." (Ritter, L., Clark, H. Kaegi, E., Morrison, H., Sieber, S. "Report of a panel on the relationship between public exposure to pesticides and cancer." Cancer 80:2019-2033,1997) billo |
