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.

Two high speed ferries that began operation on the Great Lakes this year have shut down for the winter. The Great Lakes Radio Consortium’s Chuck Quirmbach reports that for each of the boats, the first season did not go according to plan:


The Lake Express Ferry that crossed Lake Michigan between Milwaukee and Muskegon exceeded predictions and carried more than 120-thousand passengers. But the boat cancelled its November and December schedule because of a low number of bookings. Lake Express President Kenneth Szallai insists the problem is not people being reluctant to cruise the lake in cold weather. He says the company just didn’t do enough to market the late-season service.


“People are used to the traditional ferries ending up in October… and because we didn’t do our part of it… they didn’t realize we’d be operating and so our sales were kind of flat for those two months.”


Szallai says the Lake Express will again carry passengers next spring. Another high speed ferry between Toronto and Rochester, New York abruptly shut down in early September. A Rochester newspaper reports problems include, quote, questionable business decisions, bad luck and lack of cash. It’s unclear when the boat will resume service.
