Skip to comments.Mongooses near U.S. bases have high PCB levels (Japan)

Japanese researchers have detected high levels of toxic polychlorinated biphenyls in mongooses found near two U.S. military bases in Okinawa in a recent study.
The team of researchers from Ehime University and Okinawas Meio University told Kyodo News the source of the pollution was probably transformers or other equipment containing PCBs, and said further studies are necessary, given that nearby residents and other animals could be contaminated as well.
The discovery points to the need for a thorough investigation into how equipment containing PCBs has been and is currently used. U.S. bases in Okinawa are said to have a lot of equipment that still contains PCBs.
The team studied seven mongooses that were either killed on roads or captured for studies on their habitats near U.S. Marine Corps Air Station Futenma and the Makiminato Service Area (Camp Kinser), both on Okinawa Island, in August and September 2008. Their carcasses were preserved for further study.
The researchers found up to 890 nanograms of mono-ortho PCBs, a specific type of PCB with a high toxicity similar to dioxin, per gram of liver fat, and an average of 310 nanograms, both higher than levels reported in mongooses in other parts of Okinawa or in cats, wild boars and raccoons elsewhere in Japan.

Let's burn some lead
Dead mongooses versus Fukushima. Hmm. Let me think, which do I care about more?
I vote for “dead mongooses.”
You should have put up a picture of Don ‘The Snake’ Prudhomme’s car too..........Just saying :)
Wouldn’t it be mongeese?
Wouldn’t it be mongeese?
It could be mongeese. So I’m voting for “dead mongeese” as most important Asia-Pacific news item for today. However, my Freeper posting on “zombie pigeons” a few days ago should never be forgotten either.
PCBs are harmless. The pond where I swam as a boy later tested 200,000 ppm for PCBs in the mud, and I am chugging along just fine. This is all treehugger scare tactics.
Michael Fumento agrees:
The most comprehensive study of long-term health effects of PCB exposure involved more than 7,000 General Electric workers with an average of 31 years on the job. Chiefly authored by Renate Kimbrough, the March 1999 Journal of Occupational and Environmental Medicine report found that PCB-exposed workers had a lower rate of cancer deaths than the national average despite sometimes massive levels of the chemical in their blood.
Ironically, it was Kimbrough's own rat study decades earlier that kick-started the PCB scare.
In August, a review of all published occupational exposure studies in the European Journal of Cancer Prevention reported that PCB workers "do not show any excess in all cancer mortality, or in mortality for specific cancer sites of interest."
Yet it was concluded too early to include the five-year follow-up of the Kimbrough group, which again found no abnormalities.
But the EPA won't reevaluate the chemical. After all, why consider human exposures when there's such fine rodent data? Yet even extrapolating from rodent studies, PCBs are practically pikers. In order to establish a priority rating system for rodent carcinogens Berkeley biologist Lois Gold maintains a HERP (human exposure dose/rodent potency dose) index. This rates the degree of carcinogenesis of various chemicals based on the degree to which they have caused tumors in lab animals and the amount humans absorb.
As she notes in her recent co-authored book, "Misconceptions about the Causes of Cancer," "The HERP value for PCB (is) toward the bottom of the ranking, and far below many values for naturally occurring chemicals in common foods." In fact, it has exactly the same ranking as the consumption of toast.
