Oh that. Bloody useless as I understand it.

Apparently according to something I also read the amount of carcinogen you are exposed to on a 18 minute walk next to a low but noticeable traffic (I remember it saying 20ish cars per minute) is orders of magnitude stronger in regards to cancer causing factors in daily life.

I’m not 100% certain about equating carcinogenic effects to causing cancer but I don’t know any other reason to talk about carcinogens.

Sorry to bother you, this was all a nothing burger. Sorry I asked and wasted your time, and mine too
