Epidemiologist accuses prominent EPA-funded researchers of ‘deliberate misrepresentation’ on key air pollution studies

Retired (but still active) UCLA epidemiologist Jim Enstrom challenges the notorious C. Arden Pope III and Dan Krewski to be honest.

Enstrom’s new study is described here.

His letter to Pope and Krewski is below.

Dear Professors Pope and Krewski,

I am writing you because I have strong evidence that the 1995 Pope AJRCCM article, the 2000 Krewski HEI Reanalysis Report, and the 2009 Krewski HEI Research Report 140 deliberately misrepresented and exaggerated the relationship between fine particulate matter (PM2.5) and total mortality in the ACS Cancer Prevention Study (CPS II) cohort. My evidence is described in my March 23, 2017 ICCC-12 talk and PPT “PM2.5 Does Not Cause Premature Deaths” and in my March 28, 2017 Dose-Response article “Fine Particulate Matter and Total Mortality in Cancer Prevention Study Cohort Reanalysis,” particularly Tables 2 and 3 and References 26 and 27.

My March 10, 2017 email message requested that HEI staff evaluate my evidence. My April 3, 2017 email message notified the HEI Board of Directors, HEI Research Committee, and the
HEI Review Committee of my request. HEI has not evaluated my evidence and apparently has not asked for your assistance. Thus, I make the following request directly to you as lead authors:

“In order to test the validity of my evidence, I request that you conduct a sensitivity analysis that produces tables similar to the California tables presented with your September 7, 2010 letter to CARB. Specifically, please produce tables which describe the PM2.5 and mortality relationship in the CSP II cohort for the Ohio Valley states (Indiana, Kentucky, Ohio, Pennsylvania, and West Virginia) and for the remainder of the Continental United States.” This can be done with minor modifications of the SAS Program that was used to produce the 2010 California tables.

Please complete this analysis as soon as possible and email me the results in the 2010 format so that they can be compared with the results in my Tables 2 and 3. Until you produce unequivocal results to the contrary, I will make the case that my NULL CPS II PM2.5-mortality findings are correct and support other findings that “The EPA Lied—Nobody Died.” All this new evidence reinforces the need for the HONEST Act to be passed by the U.S. Senate and signed into law.

Thank you very much for your cooperation regarding this extremely important request, which is a direct challenge to the scientific and public health validity of the EPA PM2.5 NAAQS.

Sincerely yours,

James E. Enstrom, Ph.D., M.P.H.

  1. The EPA is one of the most corrupt agencies in DC. Rhere people are huge liars, just like their old boss, Obama.

  2. I am sure that excessive particulate matter has caused my psoriasis, excessive tooth decay and ED. I have decided to start every morning buy gargling with Air Wick. I’m sure this will be an improvement in my everyday life……
