Enstrom’s Expose of Air Pollution Epidemiology Problems
نویسنده
چکیده
Dr James Enstrom’s article in the January-March 2017 issue of Dose Response titled “Fine Particulate Matter and Total Mortality in Cancer Prevention Study Cohort Reanalysis” exposes United States Environmental Protection Agency (EPA)-sponsored air pollution epidemiological research misconduct, characterized by a history of using small associations observational epidemiology to project grand claims of hundreds of thousands of deaths from fine particle air pollution. For more than 2 decades, the EPA and its sponsored epidemiologists have used this deplorable method and ignored the rule that dominates the Bradford Hill Rules of proof of causation—the importance of a robust effect as expressed in relative risks (RR) that are at least 2.0 (100% effect) or more. Enstrom exposes the perfidy. The rules on strength of association (relative risk) are discussed in depth in the chapter on epidemiology of the Federal Judicial Center’s Reference Manual on Scientific Evidence, (National Academy of Sciences Press, 3rd Edition, 2011). The authors of the epidemiology chapter include Leon Gordis, MD, MPH, DrPH, an iconic figure in epidemiology and long-time Chair of Epidemiology at Johns Hopkins University Bloomberg School of Public Health. Dr Robert Devlin, senior scientist for the EPA human experiments project of the past 3 decades, admitted in a sworn affidavit filed in a lawsuit in the Eastern District of Virginia that the EPA sponsored human exposure air pollution experiments because the epidemiological research claiming deaths from air pollution sponsored by the EPA was not proof of causation. In his sworn affidavit, excerpted here below, Dr Devlin said:

Enstrom’s article based on data from the American Cancer Society’s Second Cancer Prevention Study (CPS-II) is an important contribution to the literature on long-term relationships between mortality and air pollution exposure. It focuses on exposure uncertainties and regional differences. Neither topic has been explored in the many previous articles or critiques of CPS-II, and Enstrom’s article...

Background and aims: Air pollution is one of the health problems worldwide. Previous epidemiological studies have investigated the impacts of air pollution on respiratory and cardiovascular diseases. The aim of this study was to determine the associations between air pollution levels and different health indicators among world countries. Methods: This eco...
متن کاملFine Particulate Air Pollution and Mortality: Response to Enstrom’s Reanalysis of the American Cancer Society Cancer Prevention Study II Cohort
The first analysis of long-term exposures to air pollution and risk of mortality using the American Cancer Society Cancer Prevention Study II (ACS CPS-II) cohort was published in 1995. Subsequently, extensive independent reanalysis and multiple extended analyses were conducted. These studies have consistently demonstrated that exposure to fine particulate matter air pollution (PM2.5) is associa...
متن کاملCommentary: Linking particulate matter and sulphur concentrations to air pollution annoyance: problems of measurement, scale and control.
Jacquemin et al. address an important topic in the field of epidemiology and public health by increasing understanding of the triggers of air pollution annoyance across 25 population centres in 14 countries in Europe. No study, however commendable, is without its limitations and this one is no exception. We offer a commentary of their article ‘Annoyance Due to Air Pollution in Europe’ as a mean...
