So does PM2.5 actually kill that many people?

So does PM2.5 actually kill that many people?

Or really anyone at all? A new study just published in the journal Regulatory Toxicology and Pharmacologydrives a stake through the heart of EPA’s claims.

The study compared daily PM2.5 levels in California with daily death counts during the 13 years between 2000 to 2012. Over those 4,745 days, no association could be found between PM2.5 levels and the over two million deaths included in the analysis. EPA claims that elderly people are most vulnerable to the allegedly lethal effect of PM2.5. But the California study specifically examined this issue and found no association between PM2.5 and deaths among the elderly.

Without a doubt this is the largest and best-conducted epidemiologic study ever on PM2.5. Virtually every death in California was considered and the state is meticulous about its air-quality data. California has the ultimate range in air quality, from the best to the worst in the U.S. In comparison, previous EPA-funded studies have focused only on limited (read “cherry-picked”) urban areas, rely on guesstimated or assumed PM2.5 levels and often include deaths from accidents, homicides and other causes that can’t possibly be related to PM2.5.

What happened with Germany′s climate protection plan?  — Tallbloke’s Talkshop


The whole idea of a ‘climate protection plan’, as well as sounding like some sort of insurance racket, is loaded with suspect assumptions about supposed effects of human activities on the inherent natural variation of Earth’s ocean-atmosphere system. DW.COM reports on what’s seen by some as Germany’s Moroccan climate embarrassment, as some of its own […]

Claim: Air pollution linked to blood vessel damage in healthy young adults

Claim: Air pollution linked to blood vessel damage in healthy young adults

Uh… no.

First, in the actual study, the researchers only conclude the following (note highlighted text):screen-shot-2016-10-20-at-4-14-25-pm

So their actual conclusion is a lot smaller than their headline. But even that is an obvious false claim.

If the little bit of PM2.5 inhaled from outdoor/indoor air damaged the blood vessels of health young men, what would massive amounts of PM2.5 do to sick, old men?

Believe it or not, there are many oxygen users who smoke. Despite that each cigarette delivers PM2.5 at a rate anywhere from 10,000 to 40,000 times greater than breathing typical air, and that sick people are supposedly more vulnerable to the alleged effects of PM2.5 (according to EPA), smoking is not known to cause them any short-term harm.

The “results” of the new study just don’t jibe with the real world. That they don’t is not surprising considering that the lead researcher is C. Arden Pope, one of EPA’s main cheerleaders for the bogus notion that PM2.5 kills.

Fukushima and the Art of Knowing

Fukushima and the Art of Knowing

What prompts someone to move halfway across the world, to work in a hospital near Fukushima Daiichi Nuclear Power Plant? I can tell you.

It was first, because I didn’t know enough, and secondly, because I wanted to know more.

On March 11, 2011, Japan was struck by an earthquake and tsunami, which triggered a nuclear accident. Four years later and 9,000 kilometers away, it was February 2015, I was a master’s student at the University of Edinburgh, and a guest lecture was about to begin by Japanese researchers on their work in Fukushima.

I knew there had been a nuclear accident in Fukushima. I assumed this had led to dangerous radiation levels and increases in cancers. I had never entertained the thought of visiting.

What happens next could be described as a clash between what I thought I knew and reality.

The researchers gave a series of presentations. They showed us what they had found in Fukushima; there were overwhelmingly low levels of internal and external radiation in residents,1,2 and a mass screening of babies and children revealed that none had detectable levels of internal radiation contamination.3 Yet, other health problems were emerging; in contrast to low levels of radiation, an increased burden of diseases unrelated to radiation, such as diabetes, cardiovascular disease, hypertension and more, was being found.4,5 Particular health risks associated with evacuation were highlighted,5 including evidence that immediate evacuation of the elderly from nursing homes was associated with three times higher mortality risk that non-evacuation.6 It was presented to us that radiation may not be the biggest problem for Fukushima.

I was surprised. This appeared to be, in fact, the exact opposite of what one may think about Fukushima. This surely was not the Fukushima I had heard of or visualized, and my curiosity was piqued. I talked to the researchers and proposed an idea for further research. They, in turn, invited me to come to Fukushima to write my Master’s dissertation. I agreed.

In May 2015, I first arrived in Fukushima, and began research at Minamisoma Municipal General Hospital. I wrote my master’s dissertation, graduated, and then was offered a full-time job at the hospital, which is where I am today.

There are a lot of things I could write about, that I have learned from Fukushima. Yet one of the most unexpected parts of this experience has been the confrontation between what I thought I knew, and the reality which I found. There were few things in front of me in Fukushima that matched my original expectations, and I was struck by the feeling that I had been unaware of so much. Yet I also realized that the inaccurate ideas I previously held were surprisingly common. This has led me to think more than ever about what it means to ‘know’ something, in terms of both myself and others.

Because really, how do we know things? There’s not one answer.

Well there is one good answer. The abundance of fauna and flora around the exploded Chernobyl reactor. Teaming with wildlife, reproducing at an alarming rate, evidently no lasting harm caused by radiation.

The more effective the isolation of a building the more likely radon levels augment. Keeping things out is inversely related to keeping things in.

Residential radon exposure and risk of incident hematologic malignancies in the Cancer Prevention Study-II Nutrition Cohort

Dosimetric models show that radon, an established cause of lung cancer, delivers a non-negligible dose of alpha radiation to the bone marrow, as well as to lymphocytes in the tracheobronchial epithelium, and therefore could be related to risk of hematologic cancers. Studies of radon and hematologic cancer risk, however, have produced inconsistent results.

To date there is no published prospective, populationbased study of residential radon exposure and hematologic malignancy incidence.

We used data from the American Cancer Society Cancer Prevention Study-II Nutrition Cohort established in 1992, to examine the association between county-level residential radon exposure and risk of hematologic cancer.

The analytic cohort included 140,652 participants (66,572 men, 74,080 women) among which 3019 incident hematologic cancer cases (1711 men, 1308 women) were identified during 19 years of follow-up. Cox proportional hazard regression was used to calculate multivariable-adjusted hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for radon exposure and hematologic cancer risk.

Women living in counties with the highest mean radon concentrations (4148 Bq/m3 ) had a statistically significant higher risk of hematologic cancer compared to those living in counties with the lowest (o74 Bq/m3 ) radon levels (HR¼1.63, 95% CI:1.23–2.18), and there was evidence of a dose-response relationship (HRcontinuous¼1.38, 95% CI:1.15–1.65 per 100 Bq/m3 ; p-trend¼0.001).

There was no association between county-level radon and hematologic cancer risk among men. The findings of this large, prospective study suggest residential radon may be a risk factor for lymphoid malignancies among women. Further study is needed to confirm these findings.
