if i slowed anymore id be in reverse.

It is a no proof, overall no win type situation. Levels of PCB's appear in basically everyone because of its ubiquitous presence in our daily lives. There is no level set to determine how much causes damage, its on an individual basis. Unless you are blood tested right after an exposure, the levels will drop off anyway either by elimination or storing in fat. There is nothing you can really do about it. Chelating or fasting may actually be harmful because of rapidly releasing the pcb's into the rest of the body from the fat that they are stored in. Much like one of the diseases it causes, peripheral neuropathy, pcb damage varies with the person. People can and have been in the same place as other people , had the same exposure, yet some have had no ill effects, some develop cancer, some develop nerve damage, some develop autoimmune diseases and some respiratory. The whole thing is very frustrating.
