but no one knows what any given level of PCBs in <br />aboh,hlood or fat means. Also, these tests are <br />and are not always accurate. Akhougis <br />eCBs can affect the levels in your blood of certain <br />enzymes made by your UM, there is no reliable <br />way to relate these levels to PCB exposure. tyfany <br />other chemicals, especially alcohol, affect lives <br />enzyme levels much more than PCBs do. There- <br />forc, none of these tests is recommended as a test <br />for PCB effects. <br />. <br />Is there any treatment for PCB <br />exposure? <br />No. Once PCBs enter your body, there is no <br />way to remove them. They will naturally be slowly <br />eliminated from your body. Thi is no evidence <br />that weight -loss programs or saunas can speed up <br />their elimination - <br />Compared to other <br />cancer-causinagents, how <br />toxic are PCBs`? <br />In terms of their ability to cause cancer in <br />animals, PCBs are in the middle range. That is, <br />doses don't have any detectable effect, but <br />very large doses clearly cause an increase in animal <br />cancer rates. We don't know whether PCBs can <br />cause cancer in humane. Some workers have been <br />heavily exposed to PCBs, because for many years <br />PCBs were believed to be among the safest of <br />industrial°chemicals. Victims of yusho disease <br />were exposed to even greater amounts. Studies of <br />these groups of heavily exposed people have given <br />limited evidence of an increased cancer risk. It <br />seems dear that an occasional exposure to PCBs <br />will not substantially increase Your chane of <br />getting cancer during Your lifetime. However, it is <br />sensible to avoid exposure whenever possible. <br />Do PCBs have any other <br />health effects? <br />Years ago, many workers were frequently ex- <br />posed to PCBs without proper protection* Some of <br />them developed chloracne, a painful and persistent <br />form of acne. other than the possible increase in <br />cancer rates, this is the only health effect that has <br />been found in people who work with PCB1 <br />Some people have reported skin and eye <br />irritation, headaches, or nausea These effects are <br />usually ted with PCB fires, where other <br />chemicals are involved <br />A varietY of other symptoms were seen in <br />yusb. victims, but these people had eaten <br />substant'al amounts of PCBs and other more toric <br />such as dioxim Now that most PCB <br />91 <br />atorvkh a combined dus <br />`vapor fitter image -Your u <br />not warn.you thatPCBp; <br />
