Book Cancer Risks Associated With Elevated Levels of Drinking Water Arsenic Exposure

Download or read book Cancer Risks Associated With Elevated Levels of Drinking Water Arsenic Exposure written by F. J. Frost and published by IWA Publishing. This book was released on 2005-07-31 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2000, the USEPA reduced the drinking water arsenic MCL from 50 ?g/L to 10 ?g/L, affecting many U.S. community water systems. This study was conducted because of the large number of systems involved, the costs of compliance with the new standard, and the increasingly uncertain scientific basis for the regulation. Two large, recently conducted studies of low-dose drinking water arsenic exposures do not support the need for the regulation. The objective of this project was to examine whether lung and bladder cancer mortality or incidence rates are elevated in U.S. populations consuming drinking water that exceeds the new USEPA MCL for arsenic of 10 ?g/L. This study took place in two phases. In the first phase, the research team estimated the mean drinking water arsenic level of most U.S. counties and identified counties with a mean arsenic level >10 ?g/L and >20 ?g/L. In the second phase, they evaluated the relationships between lung and bladder cancer mortality (1950?1999) and incidence (1973?1999) in these populations using multi-level, hierarchical statistical models (i.e., MLwiN statistical software). The research team employed three approaches: (1) combining all cancer deaths for all ages across the decades (1950?1990) for which data were available, (2) conducting a subanalysis limited to the population age 50 years and older, and (3) combining cancer deaths for those decades (1960?1999) for which comparable census variables were available. Arsenic in drinking water at levels >10 ?g/L was not associated with greater mortality from bladder or lung cancer, nor was a higher level of arsenic associated with greater incidence of bladder or lung cancer. There was considerable variation between counties in both lung and bladder cancer mortality. County lung and bladder cancer mortality rates were strongly related to neighboring county lung and bladder cancer mortality rates. This relation suggests that making an adjustment for neighboring county cancer mortality rates controls the unmeasured confounding factors. Higher mortality rates for bladder and lung cancer were observed in counties designated as metropolitan and, for males, counties with a high percentage of persons employed in manufacturing. Lower mortality rates were observed in counties with higher mean educational levels and counties with a larger mean household size. These same covariate relationships were not apparent in the incidence analysis. This study did not find evidence of increased risk for lung or bladder cancer mortality or incidence from exposure to arsenic in drinking water. The findings are consistent with other recent studies of the health effects of low dose arsenic exposure and are inconsistent with the USEPA predictions of excess cancer risk from low dose arsenic exposure. Multi-level hierarchical analysis is a highly appropriate method for determining if areas with elevated drinking water contaminants have elevated health risks. It makes optimal use of existing data in a cost-effective analysis that adjusts for many covariates. It is an approach that should be considered for addressing future drinking water health effects issues. In particular, this study adds to the literature on low dose arsenic health effects, providing the first summary of mortality and cancer incidence in U.S. populations exposed to elevated drinking water arsenic. It should provide some reassurance to customers of many drinking water utilities. Originally published by AwwaRF for its subscribers in 2004.

Book Exposure to Arsenic and Atrazine from Drinking Water and Risk of Cancer

Download or read book Exposure to Arsenic and Atrazine from Drinking Water and Risk of Cancer written by Taehyun Roh and published by . This book was released on 2016 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of analysis indicate that overall cancer incidence and mortality were lower in Iowa than the US, and different trends of major cancers were found between Iowa and the US. However, prostate cancer was the most frequent type of cancer in men in both Iowa and the US and I focused on prostate cancer for further study. Lastly, based on what I found from previous studies, I conducted an ecologic study to evaluate the association of prostate cancer and arsenic in drinking water in Iowa, where exposure levels are low, but duration of exposure can be long. Spatial Poisson regressions were conducted to estimate the risk ratios of prostate cancer by tertiles of arsenic level at a county level, adjusted for demographic and risk factors. The county averages of water arsenic levels varied from 1.08 to 18.59 ppb across the counties, with three counties above the 10 ppb limit. Based on the tertiles of their arsenic levels, counties were divided into three groups: low (1.08-2.06 ppb), medium (2.07-2.98 ppb), and high (2.99-18.59 ppb). Spatial Poisson regression model analysis showed that the risk ratios of prostate cancer were 1.16 (95% CI, 1.10-1.23) and 1.28 (95% CI, 1.21-1.34) in the medium and high groups (p-trend

Book Reducing Environmental Cancer Risk

Download or read book Reducing Environmental Cancer Risk written by Suzanne H. Reuben and published by DIANE Publishing. This book was released on 2010-10 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.

Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-12-26 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Book How Tobacco Smoke Causes Disease

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
