  • The Toxicity of Fumes from Diesel Engine under Four Different Running Conditions

    It has been suggested that fumes from diesel engines make an important contribution to atmospheric pollution. This is probably because they are sometimes highly irritant and sometimes very smoky. It is well known that, because of their comparatively low carbon monoxide content, these fumes arc much less lethal than those from petrol engines.
    The leading work on diesel fumes has been done by the U.S. Bureau of Mines. Holtz, Berger, Elliott, and Schrenk (1940) analysed the fumes from engines in proper mechanical conditions, plotting the carbon monoxide, nitrogen oxides, and aldehyde content against fuel-air ratio.
    The present work was directed to ascertaining what were the main toxic constituents of diesel fumes. In order to do this, animals were exposed to the fumes, and at the same time the concentration of various constituents of the fumes was determined; pathological investigations were subsequently carried out on the exposed animals.
    In this paper, nitric oxide is designated NO, and nitrogen dioxide NO2. For conversion of parts per million to mg/m³ factors valid at 20°C have been used.

  • Helicopters at Treblinka?

    Dear AnswerMan, Both the 1971 and the 1996 edition of Michael Elkins' book *Forged in Fury* include a passage that describes the aftermath of the Aug. 2, 1943 uprising at the Treblinka concentration camp in Poland. Both editions describe the hunt for the Treblinka escapees—its Jewish inmates—in these terms: “For four days, the Germans prowled…

  • Gassing, Burning and Burying

    Let’s say, hypothetically speaking, that someone wanted to design and implement a systematic process for mass-murdering hundreds of thousands of people, in a short period of time, using poisonous gas. How might one go about doing this? This is the question that must have been brought to bear on certain high-ranking individuals in the Nazi…

  • I Was Gassed!

    I have survived carbon-monoxide poisoning, more than once. My latest carbon-monoxide poisoning was caused by an improperly installed stove ventilation fan located next to a natural-gas hot-water heater. This latest CO poisoning was the most severe. From my experience of being “gassed,” I have several observations pertaining to “Holocaust gassing” claims. As we are t,…
