Please read further don't just stop were you concluded, the ban of PCB in 2004 didn't eliminate it completely. Between in present day most electronics still have it in them. I did read the whole thing and yes many devices built before 2004 may have PCB's but miners did not exist until around 2010 so I stand by my statement. I've been involved in the design of electronic devices from initial concept through their production since the early 1970's and remember very well the transition to replacing PCB's in components. Unlike some restricted/banned materials such as lead there are no edge cases (usually military and aerospace applications) that allow their use. In the USA the last edge cases were stopped around 1985. I can safely assure you that NO electronics built anywhere in the world after 2004 have any at all. As for them still being in the environment - of course they are and it will take at least several more decades before they are greatly reduced. Thing is, that has nothing to do with this case. You are right, I've gone through different research and understood that PCB due to its toxicity didn't make it to recent day electronics some nations banned it even before 2004, USA stopped implementing it much earlier in 1979 than other nations, also it was banned in Stockholm in 2001, basically, the member from the other thread where I knew of this acronym meant 'Printed Circuit Board', no I don't think so, because similar work like I shared above was also posted under the thread, hence the confusion to why they thought that polychlorinated biphenyls exists in miners as of 2014, is that the symptoms to what happened to him and Op of this thread is similar to what PCB could cause, like I pointed out in my first response. But with your analysis, and experience in the electronic building niche backed with other research which I've done on this subject, it's of no essence doubting what you've said. Cheers.
