Detecting mercury exposure
Once absorbed and circulating, mercury becomes bound to numerous proteins, including keratin. The concentration of mercury in hair correlates with the severity of clinical symptoms. If the hair can be segregated by length, such an exercise can be useful in identifying the time of exposure.
0-15 years: not established
> or =16 years: 0.0-0.9 mcg/g of hair
Normally, hair contains <1 mcg/g mercury; any amount more than this indicates that exposure to more than normal amounts of mercury has occurred.
