Can you tell me about this hype about trace heavy metals, in small glass jars, contaminating their ozonated oil contents?

Not really, but... I may know more about ozonated oils than any Dr. here but have not heard any hype about trace heavy metals contaminating it and can't find any info online,so would like to know where you heard the hype. Some articles say ozonated oils made with a corona vs. cold plasma generator may cause contamination of the oil, but don't know what contaminants or any documentation.See http://tinyurl.com/zaz5eou.
