Summary appears to be once again nothing particularly conclusive.
> No significant association between occupational exposure to RF/MW-EMF and brain tumors was found.
> For glioma, the adjusted odds ratio for highly exposed persons compared with persons not highly exposed was 1.21 (95% confidence interval: 0.69, 2.13); for meningioma, it was 1.34 (95% confidence interval: 0.64, 2.81).
They found a very small dose-response relationship for gliomas and meningiomas and think it merits further investigation.
> However, the slight increase in risk observed with increasing duration of exposure merits further research with larger sample sizes.
This continues to feel like aspartame.
- postmodest 3y agoEvery ham I know has huffed so much vaporized lead and rosin in their day that I wouldn't blame their cancers on RF.
- iraqmtpizza 3y agoDose-response is a big deal. But it could easily be p-hacking or something.
- henearkr 3y agoIf the cancer is in the brain, it is less likely caused by rosin and more likely caused by radiations emitted near their head (if any). I would more naturally link rosin to respiratory system cancers, for example.
- korse 3y agoIs huffing rosin vapor during soldering carcinogenic? I understand the lead is problematic but I never considered the flux.
- leetbulb 3y agoI don't know about carcinogenic, some sources say yes, but I think in general, rosins vapors and its pyrolysis products are not great to inhale as it can contain some pretty nasty chemicals. Lead on the other hand vaporizes well above soldering temperatures... Can / does rosin vapor can carry lead?
- NikkiA 3y agoThe boiling point of lead is too high (1700 deg C) for it to be vapourised during soldering. Rosin has a complex molecular structure that is too big to cross the blood-brain barrier. It is a lung irritant and has an associated lung disease risk of the form of adult-onset asthma but it cannot cause brain cancer; there is no known link between rosin and any form lung cancer. Most of us don't use rosin anymore, as it's an absolutely awful flux, synthetic fluxes are more effective and don't have the same risks - although it's probably too early to say on carcinogenic risks, but needless to say with many of us gen Xers having spent our lives using synthetic flux, we'd have expected to see cancer clusters by now.
- Doxin 3y ago> The boiling point of lead is too high (1700 deg C) for it to be vapourised during soldering. You will definitely be getting lead dust on your hands when working with lead solder though. Hopefully most people are smart enough to wash their hands after soldering, regardless of lead content, but I wouldn't be surprised if a lot of hobbyists were eating lead without noticing.
- NikkiA 3y agoSoldering is best done with nitrite gloves anyway, so you don't get corrosive finger oils on everything.
- zug_zug 3y agoLet me clarify what a confidence interval is. When they say odds ratio was "1.21 (95% confidence interval: 0.69, 2.13);" they aren't saying "It's slightly higher." They are saying "We have no idea what the odds are, radio could LOWER your odds down to 69% or raise them up to 213%." Scientists treat this as a non-result, try the study again with more data. A confidence interval that IS statistically significant will have an upper-bound below one, or a lower bound above one i.e. (95% confidence interval 1.10, 3.31) meaning we can be 95% sure that this increases your odds by 10% or more [up to 331%]
