Eating whale may add mercury to your hair

Kyodo News has reported on a study that examined the relationship between whale meat consumption and mercury levels found in human hair:
Mercury levels averaged 21.6 ppm among the men and 11.9 ppm among the women, both of which are about 10 times the national average, it said.
The three people whose hair mercury levels exceeded 50 ppm were all men, the team said. The three men ate whale meat more than once a month.
The study found that mercury levels were halved in about two months if the test subjects stopped eating whale meat.
According to the researchers, those with mercury levels measuring 50 parts per million were at risk of developing neurological symptoms, and it was advised that they cut down on the amount of whale they eat.
