(Expanded 1924-1925).
- Rennert was also asked whether he confirms in his opinion that exposure to large quantities of carcinogens creates a causal relationship. His answer:
The witness, Prof. Gad Rennert: I don't think I write that way. I don't remember the text. Exposure that creates a risk, once again, it all depends on the relative risk. Okay? There can be a carcinogen that if you take it, that is, let's talk about sun, high concentration of sunlight can cause melanoma. If you go to the beach every day at 12 o'clock without protection, and if you live in Scandinavia and have two days of sun a week then you won't get cancer from sun exposure. So there is a meaning here for frequency, concentration, all these things, it's just simple logic.
Adv. Mr. D. Or Chen: You know of evidence or an article that studies by a man named Christopher Christine, who says that 3 hours of exposure to air pollution from diesel causes changes in DNA, because it makes a change in the processes of methylation, binding of the DNA alloy.
The witness, Prof. Gad Rennert: I don't know, I don't know, but there's no reason, that is, if more than one researcher has seen this thing in different environments, I have no problem accepting it. Although you should remember that in diesel, these particles, part of their characterization, is that they settle inside the lungs and cause an inflammatory response, and the response is less cellular, it is more tissueal. And when it does inflammation, something like bronchitis, that's the trigger later on for lung cancer.

Adv. Mr. D. Or Chen: The argument is that you are actually ignoring unequivocal evidence that־IARC Iraq and other entities such as WHO The causal link of exposure to certain carcinogens from industry, and not from industry, to various cancers.
The witness, Prof. Gad Rennert: You didn't hear me say that. If the carcinogen is a carcinogen in the table IARCThis means that there is proof that he knows how to make cancer. This proof is given for specific cancers, In my mouth 2.5 they found it about lung cancer and they said there was a hint of a link with bladder cancer And there is no connection with any other party.
