Your extensive negative history here on Wikipedia speaks for itself.  I am far from the only one who believes that you have, and continue to, make loaded contributions to articles that are oftentimes alarmist in nature.  I, for one, do not even think PCBs are significant enough in the grand scheme of things to be mentioned in the leading paragraph of the article.  Mentioning them under the "Pollution" heading is more than sufficient.  But again, you have enough time to hijack this article and essentially write whatever you please because editors such as myself don't really have the time to stop you.  So write whatever you want, SageRad... you win.
