Health officials are experimenting with another way to gauge the level of mercury in people who eat a lot of fish. The only test sample needed is… hair. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Doctors can already test your blood and urine for mercury. Now, as a less invasive technique, some health officials can test the hair near your scalp for the toxic chemical. There’s some debate over the quality of the tests, the lab analyses, and over what a high test reading means. The federal health warning for mercury in hair is one part per million. But that’s for susceptible populations like an unborn fetus.


Jack Spengler is a professor of environmental health at Harvard University. he recently ate a lot of fish and says his hair tested out at 3 parts per million of mercury.


“But I’m not going apoplectic about it because I know if I just watch my consumption, I can moderate that over time… and there’s that safety margin…that I suspect I’d have to be much higher for much longer to really have symptoms. ”

Prolonged high levels of the most toxic form of mercury, methyl mercury can trigger various health problems in adults such as memory loss and cardiovascular damage.

A new study finds that eating contaminated fish from the Great Lakes might have adverse effects on more people than once thought. The Great Lakes Radio Consortium’s Lester Graham reports.


For a long time health experts have recognized that small children and women of childbearing age should limit the amount of Great Lakes fish they eat. Fish contaminated with PCB’s, Polychoilnated Biphenyls, could cause developmental problems for children. This new study finds that men should also reduce their exposure to the contaminants. Susan Chantz is a researcher at the University of Illinois and the principal author of the study.


“We are seeing some impact of PCB exposure from Great Lakes fish on memory functions of adults.”


The decade long study found people who eat a lot of fish from the Great Lakes, a couple of pounds a month, generally had lower scores on memory and learning tests than those who ate less fish. For the Great Lakes Radio Consortium, this is Lester Graham.
