PCBs cause autism-like condition in newborn rats

From the Los Angeles Times:

Traces of a chemical banned 30 years ago cause brain abnormalities in newborn lab animals that are similar to defects in children with autism, according to a new study by University of California scientists.


Many scientists say that an array of chemicals in the environment are scrambling brain development and could play a role in children's learning disorders.

The new study adds to the evidence by showing that PCBs, polychlorinated biphenyls, disrupt the auditory cortex, a part of the brain that is impaired in autistic children....The new research shows brain development is skewed when animals are exposed to amounts of PCBs in the same range as some highly exposed people. It will be published in this week's online Proceedings of the National Academy of Sciences.

...Last year, two internationally known environmental scientists reported in a medical journal that industrial chemicals may be causing a "silent pandemic" of learning disorders. Dr. Philippe Grandjean of Harvard School of Public Health and Dr. Philip J. Landrigan of Mount Sinai School of Medicine identified 202 chemicals — including PCBs and mercury — that could be contributing to autism, attention deficit disorders and other neurological disorders, and they urged more human studies.

Notes:

PCBs are the stuff GE (good old Jack Welch) was dumping into the Hudson River and refusing to clean up: http://www.riverkeeper.org/campaign.php/ge_pcbs/the_facts/44

GE also purposely put waste PCBs in sand that it gave away to people to use as fillers for building and play sand for children: http://users.nac.net/chasstamm/hrfanjorg/gereport.htm

Farmed salmon is a huge source of PCBs. Our buddies at the Environmental Working Group say some supermarket salmon tested SO HIGH they recommended NEVER EAT MORE THAN ONCE. Don't eat, period, please! Fish farming is also horrible for the environment.

Horrifying! And I was hoping to move to the Hudson River Valley someday. I have understood for quite some time that pharmeaceutics and various industries have no problem experimenting on the human body. This is a very disturbing study - and I wonder how the cleanup of these toxins are going. How is my Hudson now? I will have to find out.

And thanks for the info on farmed salmon. Salmon is always one of those things I order off of restaurant menus when I don't know what else to order as I am very picky with the types of dairy or meats and oils that I eat. And I imagine that a lot of restaurant salmon is farmed. Thanks for the info as I certainly do not want to put this into my body and longer.

Hey Ali,

yeah, and farmed salmon has *0* EFAs and prrobably fed GMO corn PLUS dyes because the meat gets so sickly looking when you feed (poor) fish corn.

I dunno WHAT to suggest for you to eat, but I can tell you what NOT to eat :)
